1 Introduction

1.1 BackgroundThe Queensland Government Wireless Network (GWN) is a shared Project 25 (P25) Phase 2 trunked radiocommunication network comprising of digital voice and narrowband data that services multiple State Beneficiaries. These State Beneficiaries are distributed over a pre-defined Queensland geographical footprint. The GWN is for use by State Beneficiaries, and it is expected that the number of State Beneficiaries will increase by on-boarding of additional State Beneficiaries.

To ensure that the GWN Facility and Operational Services can be provided to all State Beneficiaries of the GWN, State Beneficiaries are required to meet certain conditions that regulate how and when they use the GWN Facility and Operational Services. Adherence is integral to meeting the business and operational requirements of all State Beneficiaries of the GWN.

1.2 PurposeThese guidelines do not form the mandatory component of the policy and are for information only. While some information communicates other mandatory obligations which may be relevant in the context of the policy (e.g. legislation), departments are strongly recommended to further investigate these obligations in light of their own business requirements, and seek legal/expert advice where necessary.

The Reasonable and Appropriate Use Guide (the guide) sets out a number of obligations that State Beneficiaries of the GWN are required to comply with. It establishes the reasonable and appropriate use conditions of the GWN Facility and Operational Services that apply to State Beneficiaries.

The guide details: responsibilities of State Beneficiaries, and specific conditions that apply to the

Planning, Operating and Reviewing phases of GWN use. general conditions that State Beneficiary personnel are required to comply with, as well

as highlighting the permitted and prohibited uses of the GWN. the concept of shared radio network, and how one State Beneficiary’s actions impact

other GWN radio users, be that intentionally or unintentionally. procedures to be followed if considering any changes, or plans to change

configurations, operations or connections to the GWN Facility. State Beneficiary requirements to monitor and periodically review their radio users

GWN operations. State Beneficiary Representatives engagement and participation obligations.

1.3 ObjectivesThe objectives of the guide are to: ensure that State Beneficiaries have effective and efficient access to and use of the

GWN provide guidance to State Beneficiaries about reasonable and appropriate use of the

GWN



ensure that State Beneficiaries understand that compliance with this guide will ensure that their operations will not impact, or be affected by other State Beneficiaries

ensure State Beneficiaries understand their obligations and responsibilities in relation to this Guide.

1.4 Intended audienceThe intended audience of this guide is State Beneficiary Representatives, State Beneficiary Radiocommunications Technical personnel, State Beneficiary Procedure and Policy writers, and similar personnel from potential On-Boarding State Beneficiaries. It is assumed that these personnel will have the required experience and knowledge of Land Mobile Radio Networks and the radiocommunications services they provide to interpret and apply this guide within their organisation.

This guide is not intended to be provided to end radio users / State Beneficiary personnel, but be incorporated in applicable training programs, policies, processes, procedures, reviews and reporting.

1.5 Related documentsThe guide is supported by the following GWN documents: GWN Partnering Agreement GWN Statement of Understanding GWN On-Boarding Induction Guide GWN Services Agreement GWN Contract Directorate Operating Charter GWN On-Boarding Requirements Template GWN Traffic Mitigation Interim Policy GWN External Agency Policy

All readers of this guide should read the above documents, as this guide assumes the reader is familiar with the content of these documents. Some information is duplicated in this guide and some information is referenced in this guide. Figure 1 below maps out the structure of the GWN documents.

Please contact the GWN Contract Directorate for copies of any documents referenced in this guide or to be included in the distribution list for future releases of documents.

1.6 Guide formatThis guide is set out in the following sections: general guidelines network planning network services network operational management

2 General guidelines

2.1 ApplicationThe conditions, requirements, obligations, guidance, and directives that make up this Guide are to be followed strictly and apply to all State Beneficiaries of the GWN*. State Beneficiaries are to ensure that they are compliant, as it is their obligation to ensure their organisation is compliant with this Guide, as State Beneficiaries are accountable for the actions of their personnel and authorised third parties.

State Beneficiaries should endeavour to ensure that their organisation’s procedures align with this Guide to enable their compliance. Elements of this guide should be considered for incorporation into: Operational Communication Plans, Concept of Operations Plans



relevant training Standard Operating and Incident Management Procedures, and any other relevant

operational documentation Business/Operational Continuity Plans and Disaster Recovery Plans

If State Beneficiaries have any concerns about any part of this Guide, they should contact the GWN Contract Directorate and ask for clarification. It is the State Beneficiary’s responsibility to ensure that the intent and purpose of this Guide are understood and agreed by their organisation.

* Unless exception is provided by the GWN Technical Authority Group.

2.2 Reporting of malpractices, inappropriate and unacceptable useState Beneficiaries should immediately self-report any inappropriate use of the GWN Facility to the GWN Contract Directorate and, if applicable, the GWN Contractor. By reporting any suspected inappropriate use, the potential impact to State Beneficiary operations can be minimised. This applies to use of the GWN Facility in any form and extends beyond the terms in this Guide. State Beneficiaries should design processes and provide training to personnel to ensure self-reporting occurs.

Failure to self-report known inappropriate use by a State Beneficiary may be referred to the GWN Executive Steering Committee.

If a State Beneficiary becomes aware of non-conformance to this Guide by another State Beneficiary they should contact the GWN Contract Directorate as soon as practicable via their State Beneficiary Representatives.

Refer to GWN Statement of Understanding sections Liability and Issue Resolution Process for further details.

2.3 Guide variationsThis guide will be, at a minimum, reviewed annually and updated if required. This guide may only be varied by the GWN Contract Directorate, but change suggestions or feedback from the State Beneficiaries is welcome and encouraged.

Major incidents or breaches of this Guide may trigger updates to this guide.

Draft revisions of this guide will be distributed to State Beneficiaries for review before being approved to final.

The GWN Contract Directorate will advise State Beneficiaries in writing of any approved variations via the GWN Technical Authority Group. It is the State Beneficiary’s obligation distribute the updated guide to appropriate representatives within their organisation and ensure relevant subsequent changes are made to their processes, procedures, and/or training.

2.4 ConfidentialityThis guide has the security classification of GWN-In-Confidence. This classification means that the guide can be only distributed to State Beneficiaries, potential State Beneficiaries, DHPW, or GWN Contractor personnel for explicit purpose of GWN related activities. Distribution to other entities or third parties requires GWN Contract Director approval.

Please refer to GWN Statement of Understanding, sections Intellectual Property, Confidentiality and Privacy and Right to Information for further details.



Any potential breaches are to be immediately reported to GWN Contract Directorate.

2.5 GWN facilityThe term GWN Facility is used regularly in all GWN documentation. In simple terms, the GWN Facility refers to all components of the GWN including subscriber equipment. To ensure there is no misinterpretation of the term the Contract definition is repeated below.

From the GWN Services Agreement Schedule 1:

Facility or GWN Facility means:

(a) prior to, in respect of a Service Area, the Date of Commercial Acceptance, the Project Works, the Temporary Works and the Subscriber Equipment to be supplied or supplied and installed for that Service Area; and

(b) on and after, in respect of a Service Area, the Date of Commercial Acceptance, the physical works, materials, plant and equipment that have been or are to be designed, supplied, constructed, installed, commissioned, operated and maintained by the Contractor pursuant to this Agreement in respect of the relevant Service Area, including Subscriber Equipment that has been or is to be supplied or supplied and installed for that Service Area,

whether on, above or below the relevant Sites (including delivered to or stored on the Sites).

2.6 GWN shared network conceptThe GWN is a shared P25 Phase 2 trunked radiocommunication network comprising of digital voice and narrowband data that services multiple State Beneficiaries. In effect, all State Beneficiaries share the network resources and therefore have a shared responsibility to use these resources efficiently.

The concepts relating to the efficient and appropriate use of a shared network cannot be over-emphasised, as these concepts are required to ensure all State Beneficiaries have equitable access to GWN resources. These concepts have resulted in this guide being developed to ensure all State Beneficiaries understand their responsibilities to the other State Beneficiaries and to ensure the greatest benefit for the State is derived from the GWN.

This guide provides guidance on the use of a shared network, like the GWN, to ensure State Beneficiaries are able to access the network when they require access.

To ensure equitable access to the GWN resources, State Beneficiaries need to consider other State Beneficiaries in any planning activities. Due to the potential impact on other State Beneficiaries, the GWN Contract Directorate must be consulted during planning activities, be this planned maintenance activities or planning changes to how your organisation utilises the GWN.

The GWN Facility and GWN Contractor performance is monitored and reviewed by the GWN Contract Directorate. This oversight should ensure that any inappropriate use of the GWN is identified before affecting other State Beneficiaries. The results of the monitoring and reviews will be communicated to State Beneficiaries at the GWN Contract Directorate’s monthly update to State Beneficiaries. The GWN Contract Directorate will discuss any identified issues with the State Beneficiary first to provide an opportunity to remedy.



As per the GWN Partnering Agreement, all State Beneficiaries are entitled to equal representation on GWN Governance forums, and active participation in these forums is encouraged to ensure the shared network concept is successfully managed.

At the conceptual level, any existing “exclusive use” infrastructure in the GWN will not be expanded upon and no additional “exclusive use” infrastructure is likely to be installed.

2.7 GWN traffic mitigation interim policyFurther to the shared network concept, and to ensure State Beneficiaries have sufficient network resources when they most require it, (eg. Responding to large scale incident) the GWN Traffic Mitigation Interim Policy has been developed by the three original State Beneficiaries with assistance from GWN Implementation Program and GWN Contract Directorate. The policy uses operational mitigation techniques rather than changes in network configuration to mitigate radio traffic.

State Beneficiaries must be familiar with the policy and ensure all their personnel are aware of how to respond when the policy is initiated and when Traffic Mitigation stages are changed.

Please refer to the GWN Traffic Mitigation Interim Policy at your earliest convenience.

It is expected that all GWN State Beneficiaries will participate and be active in the GWN Traffic Mitigation Committee, review of the interim policy and development of the permanent policy.

2.8 State beneficiary categorisationState Beneficiaries will be categorised as Tier 1, Tier 2 or Tier 3 users depending on their organisations nature and functions. The categorisation was developed by the National Coordinating Committee for Government Radiocommunications (NCCGR) and is used by Australian Communications and Media Authority (ACMA).

State Beneficiary Categorisation affects how a State Beneficiary will respond to Traffic Mitigation Stages under the GWN Traffic Mitigation Interim Policy.

For further information about categorisations refer to GWN Governance Board Terms of Reference, GWN Traffic Mitigation Interim Policy and ACMA document Frequency Assignment Practice Guideline No. 4 – assigning harmonised government spectrum in 400 MHz band.

2.9 GWN contract directorate engagementThe GWN Contract Directorate’s rights, responsibilities, obligations and services are described in the Operating Charter for the GWN Contract Directorate (the Operating Charter).

The GWN Contract Directorate’s services that are set out in the Operating Charter are funded by Treasury, including the provision of a GWN Customer Relationship Manager who acts as a single point of contact between the Contract Directorate and the State Beneficiary. State Beneficiaries are encouraged to engage the GWN Contract Directorate about planning and operational activities. GWN operational enquiries should be directed at GWN Service Desk as per following section.

If the State Beneficiary has any queries or concerns about this guide, they should engage the GWN Contract Directorate Customer Relationship Manager in the first instance. Refer to the Operating Charter for GWN Contract Directorate contact details.



2.10 GWN service desk and network operations communications centreUnder the GWN Services Agreement the GWN Contractor is required to provide a Service Desk and Network Operations Communication Centre (NOCC) on a 24 hours per day, 365 days per year basis.

State Beneficiaries need to ensure that all personnel are provided training in what services the GWN Service Desk and NOCC provide, how and when to contact, and when not to contact the GWN Service Desk, to ensure the service is utilised as intended.

The State Beneficiary, during on-boarding, will provide a list of authorised State Beneficiary Representatives that have appropriate delegations and authority for requests to the GWN Service Desk, as some request may incur a fee, while others may require an appropriate authorisation to proceed. Changes to authorisations and delegations should be reported to the GWN Service Desk.

Refer to GWN Service Management Handbook (Telstra document) which details how the GWN Service Desk operates and how State Beneficiaries can engage with GWN Service Desk, and refer to the GWN Service Request Catalogue which details all the standard service requests.

2.11 GWN governance forumsRefer to the GWN Participating Agency Partnering Agreement for details about the GWN Governance.

The GWN Technical Authority Group also performs a Change Advisory Board (CAB) function to assess and validate the technical designs, strategies and innovation in the GWN technologies or business processes prior to implementation of any solutions or changes that are proposed by the GWN Contractor or State Beneficiaries.

Requests received by the GWN Contract Directorate that are determined to have the potential to affect other State Beneficiaries will be referred to the GWN Technical Authority Group CAB for review and consideration.

2.12 Access to GWN facilityAs per the GWN Statement of Understanding, State Beneficiaries will grant nominated personnel of the GWN Contractor necessary and appropriate access to the State Beneficiary's facilities, infrastructure and systems as agreed with or directed by the GWN Contract Directorate.

As required under the Radiocommunications Act 1992 (Cth) Section 114 Licensees may authorise third party users; An Instrument of Authority has been drafted and signed by the Director General of DSITI which authorises other organisations to utilise DSITI radiocommunications licenses.

NB: At time of publication of this update, the Director General of DHPW has not signed the Instrument of Authority, but will in due course once the ACMA licenses have been changed into the name of DHPW.

Access to Australian Communications and Media Authority (ACMA) personnel, investigating interference, could be required under the Radiocommunications Act 1992 (Cth). State Beneficiaries should immediately notify the GWN Contract Directorate and GWN Contractor of this access request and / or interference investigation.



2.13 State beneficiaries personnelState Beneficiaries are to ensure that any staffing changes (recruitment, role changes, secondment, and termination) are managed according to best industry practice and to ensure that GWN privileges and accounts are included in State Beneficiary processes.

2.14 GWN contract directorate service reviewsThe services specified within this guide, but not limited to, will be periodically monitored and reviewed by the GWN Contract Directorate. State Beneficiaries are to be able to demonstrate they are performing internal periodic monitoring and reviews of services, especially services that could potentially impact other State Beneficiaries. State Beneficiaries are to co-operate and participate in GWN Contract Directorate reviews. Outcomes of such reviews may be submitted to the GWN Governance Forums. State Beneficiaries may be required to justify the operational use of these services and may be directed to reduce use or investigate alternatives. These directives will be for the benefit of all State Beneficiaries accessing the GWN.

The GWN Contract Directorate may engage third parties to perform reviews under the endorsement / approval of GWN Contract Director, and hence State Beneficiaries may be directed to engage with this third party.

3 Network planningThe following sections provide guidance and conditions on Network Planning considerations in planning to use the GWN or planning future changes in use. This is not an exhaustive list of all Network Planning considerations.

3.1 State beneficiary representativesState Beneficiaries need to understand their obligation to provide suitable representatives of their organisation to interface to the GWN, be that from an organisational change management, technical, operational, planning, training, vehicle fleet, subscriber fleet, communications centre, reporting, financial approval or governance perspective. Suitable and well trained representatives are required to ensure that all benefits of the GWN are realised for the State Beneficiary.

State Beneficiaries are required to provide State Beneficiary Representatives, and adequately resource these representatives to perform the role fully.

A State Beneficiary Representative is not required for every stream mentioned above, but the State Beneficiary Representative must know who and how to liaise with relevant internal stakeholders from those streams to ensure effective and efficient GWN operations.

State Beneficiaries need to ensure that their representatives have the correct level of authorisation, or well defined authorisation channels, to perform GWN related activities. State Beneficiaries should provide the GWN Contractor with a list of representatives and what authority these representatives have. The following examples will be helpful for State Beneficiaries to consider: who has authority to request deployment of Deployable Mobile Radio Transmission

Site? who has authority to request a Location Services report for the subscriber fleet? who has authority to request for radios to be inhibited or uninhibited? what GWN Service Requests need restricted authority?



who has financial delegation to approve Modification Price Requests?

State Beneficiaries are actively encouraged to participate in all facets of the efficient use and operation of the GWN.

Contact details of the relevant State Beneficiaries Representatives shall be provided, and periodically updated, to the GWN Contract Directorate and GWN Contractor.

State Beneficiary Representatives will be the State Beneficiary’s escalation point for any service issues. State Beneficiary Representatives will then, if required, escalate issues to the GWN Contract Directorate.

3.2 Fleetmap managementFleetmap Management, or Fleetmapping, is the process of configuring the features and programming parameters of a system to function according to the unique operational requirements of each State Beneficiary.

Fleetmapping can be thought of as: assigning talkgroups to the radios issued to personnel assigning talkgroups to the dispatcher control positions defining the feature subsets available to the personnel using the radios and dispatcher

control positions

A fleetmap determines how the radiocommunications for each user group of an organisation is controlled. Through controlling radiocommunications between different user groups and between individuals within a group, the radiocommunications system resources are used efficiently.

State Beneficiaries are required to fully participate in the development and periodic review of their organisations Fleetmap. State Beneficiaries need to understand that a thoroughly developed fleetmap will underpin successful transition to GWN operations and maximise the benefits that the GWN can provide.

Fleetmaps will be reviewed as part of, and may be considered in Capacity Management activities.

The GWN Contract Directorate reserves the right review a State Beneficiaries Fleetmap and make a determination about if the Fleetmap promotes efficient use of the GWN.

The GWN Contract Directorate will be responsible for the management of the GWN Master Fleetmap, as per the Operating Charter for GWN Contract Directorate, and any requested changes to the Fleetmap will be evaluated against available GWN Capacity. The GWN Contract Directorate may reject proposed Fleetmap changes on the basis of an unacceptable increase in capacity usage. The GWN Contract Directorate will refer any proposed fleetmap changes that could affect other State Beneficiaries to the GWN Technical Authority Group CAB.

Subscriber Equipment Radio Identification Numbering will align with the GWN Numbering Plan which is compliant with the draft NCCGR National Interoperability Framework Radio Standardisation Project - P25 Radio ID Format.

3.2.1 Talkgroup busy queue priorities

When a GWN site is in congestion, a busy queue will manage which radio users are given radio access next, as described in Section Error: Reference source not found above. Priority in this queue can be given to individual talkgroups. Hence, talkgroup calls in the busy queue with the highest priority are serviced first. A priority will be assigned to a



talkgroup from 1 to 10, with 1 the highest priority. This priority is called Talkgroup Busy Queue Priority or also known as Talkgroup Priority.

All current State Beneficiaries talkgroups have the same priority, thus this priority functionality is effectively nulled out or effectively not used. It is intended for all State Beneficiaries to have the same priority, but Tier 2 and Tier 3 State Beneficiaries may be directed to use lower talkgroup priorities.

The current Talkgroup Priority scheme is: Emergency Call talkgroups are given priority number 1, Training talkgroups are given priority number 5 and all other talkgroups are given priority number 4.

Any change to / review of the current talkgroup priority scheme will require GWN Technical Authority Group approval.

3.2.2 Interoperability between GWN beneficiaries

All State Beneficiaries will have interoperability talkgroups in their Fleetmaps to allow for interoperability between State Beneficiaries and potentially Interstate Agencies, as outlined in GWN Interoperability Talkgroups Strategy. The Strategy outlines the minimum list of interoperability talkgroups required in every radio. All State Beneficiaries will be required to have unencrypted general interoperability talkgroups to facilitate interoperability with any future Agency that does not have encryption.

3.3 Change managementJust as there is a requirement on the GWN Contractor, there is a requirement on the State Beneficiary to follow industry standard Change Management processes. If a State Beneficiary is to make a change to equipment connected to the GWN Facility or using shared infrastructure (eg. mains or UPS power), GWN Change Management Processes must be followed.

The State Beneficiary will ensure all Building / Facility Managers, where GWN equipment is housed, are aware of the obligations to provide details of scheduled maintenance or planned changes to GWN Contract Directorate and the GWN Contractor with sufficient time for processing.

Please refer to GWN Contract Directorate Operating Charter section GWN Change Management and GWN Statement of Understanding section Change Management for further details and engage the GWN Contract Directorate for further clarification.

3.4 Planned eventsA Planned Event is any pre-planned event that a State Beneficiary could require or utilise additional GWN resources. These resources could be additional subscriber equipment, additional coverage, additional capacity, additional GWN Contractor support, etc. If an event could generate more than average GWN radio traffic, it can be considered a Planned Event.

Examples of Planned Events are: Riverfire large scale or multi agency training exercises dignitary protection activities large permitted fire back burning activities severe or Catastrophic Fire Danger days



Commonwealth Games Gold Coast V8 Supercars

State Beneficiaries should create a 12 month forecast of events, and provide this forecast to the Traffic Mitigation Committee, as per the GWN Traffic Mitigation Interim Policy.

Unplanned Events will be discussed below in section 5.2.

Please engage the GWN Contract Directorate to discuss any Planned Event requirements

3.5 Special event nominationUnder the GWN Services Agreement, section 11. Special Events, a Special Event can be nominated. The State can nominate Special Events, where during the period of this Special Event, the GWN Contractor cannot make any changes to the GWN that could cause or contribute to any degradation to or interruption of GWN Services. The Special Event nomination effectively creates a Network Change Embargo for the period of the event.

The Special Event Nomination can be discussed during Planned Events planning. Engage with the GWN Contract Directorate to discuss how a Special Event Nomination can be made.

3.6 TrainingAs per the GWN Statement of Understanding, State Beneficiaries are required to ensure their personnel, who are users of the GWN, are suitably trained in all facets of the GWN including terms, conditions and guidance provided in this guide. This includes periodic re-training, incorporating learnings from use of the GWN, and upskilling of State Beneficiaries Representatives. State Beneficiaries must ensure their State Beneficiary Representatives are suitably trained for the role and maintain a minimum level of skill and knowledge to adequately discharge their obligations.

3.6.1 Traffic dragging

In almost all major inquiries into Public Safety Agencies response to natural disasters, it is reported that radio users, who were not operationally involved, listened to the dispatch / incident channels / talkgroups, thus consuming radio resources and causing radio network congestion. This congestion causes radio users that operationally require use of the radio network to get busies. This scenario is called Traffic Dragging.

Note: Talkgroup Patching can also be a cause of Traffic Dragging, as stated in South Australian 2015 Pinery Bushfire report. In this instance, SAPOL communications from outside of bushfire region were rebroadcast into the bushfire region due to practise of talkgroup patching. Refer to section 5.18.

State Beneficiaries are required to train their personnel so they understand that they are not to listen in on dispatch / incident talkgroups during an emergent situation. State Beneficiaries personnel need to completely understand what Traffic Dragging is, what the cause is, what the network effect is, so personnel understand the reasoning behind this guidance. State Beneficiary personnel are made explicitly aware that dragging of traffic is not to occur and considered inappropriate use. State Beneficiaries self-report any instances of Traffic Dragging and the remediation that was performed to ensure no reoccurrence in the future.

State Beneficiary personnel who require the capability to listen to dispatch / incident talkgroups from outside of the area, should consider procuring Remote Radio Only Dispatch Consoles, as per section 4.5.1.



3.7 Encryption managementAll Tier 1 State Beneficiaries are required to use encryption for all voice radiocommunications. Non Tier 1 State Beneficiaries can elect not to use encryption for their radiocommunications.

By default, encryption on the GWN is managed by QPS on behalf of all GWN State Beneficiaries. A State Beneficiary Encryption Liaison Officer is required to liaise with the QPS Encryption Manager.

All GWN interoperability talkgroups are encrypted. Although a non Tier 1 State Beneficiary may elect not to utilise encryption, all subscriber equipment is required to be equipped with encryption to allow radiocommunications on the interoperability talkgroups.

If a State Beneficiary would like to manage their own encryption this can be arranged. Contact the GWN Contract Directorate to discuss encryption management requirements.

3.8 Capacity managementEach State Beneficiary may be requested to participate in Capacity Management activities with the GWN Contract Directorate, the GWN Contractor and other parties approved by the GWN Contract Directorate to document, monitor and model the capacity being sought by the State Beneficiary.

3.9 State beneficiary led initiativesState Beneficiaries are encouraged to maximise the benefits that the GWN can provide their organisation. State Beneficiaries may initiate programs of work to investigate solutions to integrate software and/or hardware systems into the GWN, innovative uses of the GWN and interoperability with other non-GWN organisations. Current solutions that are integrated into the GWN are Computer Aided Dispatch (CAD) systems and there are currently projects underway to provide Mobile Data Terminals (MDTs) in vehicles. These initiatives, although State Beneficiary led, are required to be endorsed by the GWN Technical Authority Group (TAG) before they proceed. State Beneficiary Representatives should initiate the endorsement via the GWN Contract Directorate and provide updates on the results and outcomes.

The GWN Contract Directorate and GWN Contractor are to be considered as informational stakeholders. Nominees will be provided, to ensure developments are communicated. The GWN Contractor can request updates on initiatives directly.

State Beneficiaries can engage consultants to manage all, or parts of their initiative, but engagement of all consultants requires GWN Contract Director approval and may be subject to further conditions.

4 Network servicesThe following sections provide guidance and conditions on use of GWN Network Services or have corresponding sections in the Network Operations Management section. This is not an exhaustive list of all services that the GWN provides.

4.1 GWN service areaThe GWN Service Area provides coverage to South East Queensland, including Toowoomba. The following Local Government Areas are covered:



Brisbane Redland Logan Ipswich Somerset Moreton Bay Sunshine Coast Lockyer Valley Scenic Rim Toowoomba Gold Coast

Figure 2: GWN SEQ Service Area

GWN Coverage maps are available via the GWN Web Portal and GWN Dashboard.

State Beneficiaries need to ensure their personnel are aware of the boundaries of the GWN Service Area.

4.2 GWN coverage typesThe GWN provides multiple types of coverage services. Each of the coverage areas has specific End User Receive Levels. The coverage areas have been drive tested, measured, passed and independently certified against P25 Standard TSB-88 Wireless Communications Systems Performance in Noise and Interference-limited Situations.

The GWN provides the following types of coverage or covered areas: outdoor mobile outdoor portable dwelling indoor portable building indoor portable enhanced indoor portable aircraft mobile maritime mobile



tunnels portable

Please contact the GWN Contract Directorate if you would like information about the specific coverage areas and / or end user receive levels for each coverage type.

4.3 GWN tunnel coverageAll major car and bus tunnels such as Clem 7, Airportlink, Legacy Way and the North and South East Busways have GWN coverage.

GWN Tunnel Coverage is not provided under the GWN Services Contract but standard Incident Management processes are still to be followed. Tunnels coverage faults are still to be reported to the GWN Service Desk. Further details can be obtained by contacting the GWN Contract Directorate.

4.4 Text messagingThe GWN provides two forms of text messaging functionality. The first form is Status Messaging, which sends pre-written short messages or canned messages. These pre-written messages are specified as part of the Fleetmap. Status Messaging is a standard service of the P25 Standard.

The second form of text messaging is Advanced Messaging Solution (AMS) which will provide enabled users the ability to send and receive text messages of up to 200 displayable characters to and from their radio terminals and dispatch consoles.

The use of text messaging is encouraged to reduce unnecessary voice traffic and GWN Governance Forums may direct the State Beneficiary to investigate use of text messaging with the intent of reducing State Beneficiary voice traffic where possible. Note that text messaging has secondary priority to voice traffic and therefore can experience inherent delays during heavy voice transmission periods.

4.5 Dispatch consolesDispatch Consoles are effectively IP connected radios that have the ability to monitor and communicate on multiple talkgroups, including the ability to patch talkgroup calls.

The Console requires a Profile which is developed as part of Fleetmapping.

Dispatch Consoles are alarmed. Shutting down the Consoles generates an alarm and resultant Failure Event in the GWN NOCC. Users must not restart Consoles without first contacting the GWN Service Desk.

State Beneficiaries are to implement training, processes and procedures to ensure Dispatch Consoles are used as intended and do not cause unintentional Failure Events. Any identified usage issues need to be communicated to Console users.

State Beneficiaries are to self-report any user errors that result in unintended radio use and unintentional Failure Events.

4.5.1 Remote radio only dispatch consoles

Remote Radio Only Dispatch Consoles, also known as IP Consoles, are laptops that can connect into the GWN Facility via Public Safety Network (PSN) or via Telstra 4G. These IP Consoles provide limited functionality but provide the ability to listen and communicate to talkgroups without using any GWN radio site capacity. Being a laptop they need to be secured, and in the instance of loss or theft, should be reported to GWN Service Desk immediately.



4.6 Voice and data loggingAll voice and data communications on the GWN Facility are logged for the life of the GWN Contract.* State Beneficiaries can retrieve and listen to voice recordings for operational purposes via a Nice Inform Replay Station. State Beneficiaries can only access their own organisations recordings. State Beneficiary personnel who have authority to access these logs are reviewed periodically.

State Beneficiary personnel should be made aware that all radiocommunications are recorded and can be retrieved.

* Note – By exception, State Beneficiaries can request voice traffic not to be recorded.

4.7 GWN narrowband dataThe GWN provides narrowband data. The use of narrowband data will be strictly controlled to ensure satisfactory performance of existing services that utilise narrowband data. If not captured during on-boarding business requirements gathering, a request should be made to the GWN Contract Directorate to initiate a narrowband data trial.

Note that being a State Beneficiary does not automatically allow your organisation to utilise narrowband data, and would require GWN Technical Authority Group approval.

Engage the GWN Contract Directorate to discuss any potential narrowband data requirements.

4.8 Deployable mobile radio transmission siteThe Deployable Mobile Radio Transmission Site (DMRTS) is a portable and fully self-contained vehicle trailer mounted GWN Radio Site equipped with 23 metre pneumatic telescopic mast. The DMRTS can be deployed anywhere in the State and provide radiocommunications to all other GWN radio users and console operators.

DMRTS provide the full functionality and equivalent coverage, for equivalent antenna height, of an existing GWN site. The DMRTS can be powered by mains power or by on board generator. Backhaul transmission connectivity can be provided by optic fibre or satellite.

Final determination of type of backhaul connectivity, terrestrial or satellite, to be used will be determined by availability of suitable carrier services.

State Beneficiaries can request DMRTS deployments via the GWN Service Desk for unplanned events, as per GWN DMRTS Policy and Procedures. State Beneficiaries Representatives have the authority to request unplanned DMRTS deployments. The GWN Service Desk will assume the State Beneficiaries Representatives have financial delegation for this deployment. The list of State Beneficiary Representatives that have unplanned deployment authority should be reviewed periodically.

Refer to GWN DMRTS Policy and Procedures document for further information.

Contact the GWN Contract Directorate for GWN DMRTS Deployment Request Template.

4.9 Aircraft operationsThe GWN Facility consists of four aero sites to provide GWN Aircraft Coverage. The Aircraft Mobile Coverage Area provides coverage beyond the GWN Service Area. Refer to Figure 3 below.



Aircraft operating on the GWN notionally utilise dedicated Aeronautical talkgroups above 1000m, and can operate on Terrestrial talkgroups below that 1000m.

Special requirements gathering will be required to determine if Aircraft Coverage is suitable for your applications.

Inappropriate use of radios in aircraft has the potential to cause mass interference to terrestrial GWN sites and could result in many “illegal carrier” alarms occurring, which result in Failure Events being generated by the GWN NOCC.

Portable radios with aero codeplugs can only be used by suitably trained personnel from within aircraft. Portable radios with non aero codeplugs must not be used inside of aircraft without prior approval from GWN Technical Authority Group. Use of portable radios with non aero codeplugs could will generate interference across the GWN.

State Beneficiary personnel, that will utilise Aircraft Coverage, should be provided with additional training to understand the idiosyncrasies of use of Aircraft Coverage.

Figure 3: GWN Aircraft Mobile Coverage Area (blue) and GWN Service Area (yellow).

4.10 Over the air programmingOver The Air Programming (OTAP) functionality allows radios to be re-programmed via the GWN radio network and hence removing the need for the radio to be physically re-touched. OTAP functionality is designed for small changes on batches of radios or singular full reprograms. OTAP is not intended or designed to be a function that allows full



reprogramming of subscriber equipment fleets. The radio user is required to physically initiate the reprogram on the radio and makes the radio unusable while reprogramming.

OTAP reprograms will be limited to the Bulk OTAP Limit which is currently set at 50.

The OTAP queue will be kept to less than the OTAP Queue Limit, which is currently set at 100, to allow efficient OTAP usage.

If the State Beneficiary is to provide resources to visit locations to ensure radios are reprogrammed successfully, an exemption to the Bulk OTAP Limit / OTAP Queue Limit may be approved by the GWN Technical Authority Group.

Engage the GWN Contract Directorate to discuss requirements, and obtain current Bulk OTAP Limit and OTAP Queue Limit values.

Many State Beneficiaries have subscriber equipment caches. If these radios are to be reprogrammed, the cache should be delivered to Motorola Service Centre to be reprogrammed. OTAP is not to be used for reprogramming subscriber equipment caches.

4.11 ATIA dataAir Traffic Information Access (ATIA) data is a record of all signalling information on the GWN. This data contains information like talkgroup and site affiliation and de-affiliation information for each radio user, but does not contain voice traffic recordings or narrowband data traffic records. The ATIA data can be considered the official record and single point of truth for post analysis. The GWN reporting solutions use the ATIA data as their primary data source.

The ATIA data can be sourced via the GWN Contractor, upon approval from the GWN Contract Director, to perform network traffic analysis.

Contact the GWN Contract Directorate to discuss ATIA data requirements. ATIA data is not to be distributed to third parties without the written approval of the GWN Contract Director. Requests for ATIA data may be referred to GWN Governance Forums.

5 Network operations managementThe following sections discuss the operational management of GWN Facility services, guidance and conditions associated with the acceptable use and post monitoring of these services.

5.1 Incident managementAs per the GWN Statement of Understanding, the GWN Contract Directorate provides oversight to the Incident Management function that is provided by the GWN Service Desk, to ensure quality of the service is maintained and improves over time. State Beneficiaries should escalate any Incident Management issues or process failures to the GWN Contract Directorate.

The GWN Incident Management capability focuses on restoration of GWN services to the State Beneficiaries as quickly as possible, minimising impact on their operations and ensuring the best levels of service quality and availability are maintained. Incident Management scope includes network infrastructure, subscriber equipment, GWN Service Desk and any supporting infrastructure.



State Beneficiaries must ensure their personnel are familiar with Incident Management processes. For example; how do users report faulty subscriber equipment? How do users report poor network performance?

State Beneficiaries need to determine which personnel in their organisation are authorised or are required to receive Incident Management email notifications. This list of personnel needs to be periodically reviewed. Updates to email distribution lists can be done via Service Request to the GWN Service Desk.

Any Incident Management issues should be reported / escalated to the GWN Contract Directorate via State Beneficiary Representatives.

5.2 Unplanned eventsAn unplanned event is any unforeseen incident that a State Beneficiary could require or utilise additional GWN resources. These resources could be additional subscriber equipment, additional coverage, additional capacity, additional GWN Contractor support, etc. If an event could generate more than average GWN radio traffic, it can be considered an Unplanned Event.

Examples of unplanned events are: hostage situation school bus accident apartment building fire (eg. flammable cladding) industrial liquid spill

State Beneficiary Representatives should consider invoking the GWN Traffic Mitigation Interim Policy in these scenarios.

5.3 Network management workstationThe Network Management Workstation (NMWS) provides the ability for the GWN Contractor to provide on-site monitoring and GWN configuration changes. The NMWS also provides the ability for State Beneficiaries to view Near Real Time Reporting via the Genesis software suite.

Physically the NMWS is actually two computers, one to provide GWN Contractor access to make configuration changes, and the other for GWN Contractors or State Beneficiaries to access Near Real Time Reporting functionality.

Only authorised and trained State Beneficiaries Representatives and personnel are able to access the NMWS for the purposes of Near Real Time Reporting.

As the NMWS is not connected to the internet, the only way to transfer files is by USB flash drive.

5.4 GWN web portalThe GWN Web Portal is accessible via the Internet and provides the following functionality: geographical view (GWN coverage) site status post event reporting incident management interface service requests scheduled / periodic reporting



The functionality is provided via User Profiles, therefore access to functionality can be assigned to different roles within the State Beneficiaries organisation.

All information contained on the GWN Web Portal is GWN-In-Confidence as per section Error: Reference source not found.

5.5 Post event and near real time network usage reportingThe GWN Network Event Logging allows the GWN Facility to provide reporting functionality. This functionality is presented as Post Event Reporting and Near Real Time Reporting. This reporting functionality allows State Beneficiaries to review the usage of the radiocommunications operations.

Post Event Reporting allows State Beneficiaries to run reports on a multitude of parameters over specified periods and export to a spreadsheet for further analysis. As mentioned in section 5.4 above, Post Event Reporting is accessed via the GWN Web Portal.

Near Real Time Network Usage Reporting allows State Beneficiaries to view the network performance of the GWN is near real time. Near Real Time Reporting is accessed via the Network Management Workstation as described in section 5.3 above.

Only authorised and suitably trained State Beneficiary GWN Representatives will be provided access to reporting functionality.

All information provided via reporting functionality is GWN-In-Confidence as per section Error: Reference source not found.

5.6 Emergency servicesEmergency Alarm, Emergency Call and Remote Monitor services are categorised under the generic term Emergency Services. Emergency call usage is closely monitored, and is intended to be only used for authorised purposes relating to personnel safety scenarios.

The use of Emergency Services should be closely monitored by State Beneficiaries and reviewed. It is an obligation of the State Beneficiary to ensure no unauthorised or unacceptable use of these services occur by their personnel and that periodic reviews of use by personnel will be performed. The outcomes of these reviews should be acted upon to ensure personnel use the Emergency Services appropriately.

Unauthorised or inappropriate use can occur in times of congestion. Due to the high priority of an Emergency Call, radio users can incorrectly use the Emergency Call functionality to make a talkgroup call. The high priority call will disconnect another call in progress with no regard to the importance of that call.

The GWN Contract Directorate may periodically review use of these services and request State Beneficiaries to participate in such reviews.

State Beneficiaries are to implement training, processes, and procedures to ensure Emergency Services are used as intended.

The GWN Contractor produces a monthly R19 Scheduled Periodic Monthly Report that contains report of all emergency activity for the previous month. This report is available on the GWN Web Portal 10 business days after the start of the new month.

5.6.1 Remote monitor

The Remote Monitor functionality could be used to listen in on conversations without the knowledge of the persons making the conversation, and as the Remote Monitor



functionality uses a telecommunication system, its use for purposes other than to respond to a request for emergency assistance could be considered illegal.

Under the Telecommunications (Interception and Access) Act 1979 (Cth) Part 2-1 Section 6, it is illegal to listen in on conversation via telecommunication system without the knowledge of the person making the communication, unless it to respond to a request for emergency assistance.

Due to the potential misuse of the Remote Monitor functionality, Trigger Reports are generated when the Remote Monitor function is used. The Remote Monitor Trigger Report provides the Dispatch Console ID and Alias. State Beneficiaries will be required to ensure that the Trigger Reports are sent to correct managerial personnel to ensure that oversight of the legal use of the Remote Monitor function is occurring. State Beneficiaries will also be required to review usage of Remote Monitor monthly.

The Invasion of Privacy Act 1971 (Qld) Section 43 Prohibition on use of listening devices has been updated to state the prohibition does not apply to public safety operational scenarios. Refer to Section 43, subsection 2e for further specific details.

The GWN Contract Directorate may periodically review use of these services and request State Beneficiaries to participate in such reviews.

5.7 Individual callsThere are two types of individual calls available to GWN radio users: private calls (direct calls between two radios, or between a radio and a console

operator) telephone Interconnect calls (direct calls between a radio subscriber and a telephone

user)

Due to individual calls using dedicated network capacity, the use of these types of calls need to be restricted to authorised users and the use periodically reviewed. Use of this functionality by personnel should be restricted via Fleetmapping. That is, only personnel who require the functionality will have the functionality programmed into their radios.

The GWN Contract Directorate will monitor usage periodically and report abnormal usage.

5.8 Location servicesCurrently all GWN Certified Subscriber Equipment support Location Services. GWN Location Services provide Global Positioning Service (GPS) updates, including speed and direction, of subscriber equipment.

The rate at which subscriber equipment provides location updates is known as cadence. The cadence rates for different types of subscriber equipment will be developed during Fleetmapping.

The cadence rates are proportional to the amount of network capacity used. As a result of Capacity Management reviews, cadence rates may need to be changed.

A cooperative approach will be used to review cadence rates, but GWN Governance Forums may direct the GWN Contractor to reduce cadence rates to reduce data channel network usage due to congestion.

Locations Services use GPS to provide location. GPS has inherent limitations, such as 15m nominal accuracy, low accuracy when the sky is shadowed, reflections from buildings and GPS wobble. Also, when a radio is indoors or underground, the subscriber equipment transmits its last known GPS location. In rare occasions, radios have been turned off a long



distance away, and then turned on indoors. The radio can continue to update its last known location which could be many kilometres away.

Location updates are recorded and stored for the life of the Contract by the GWN Contractor. State Beneficiaries may request reports of their personnel’s location update records via the GWN Service Desk.

State Beneficiaries personnel access to location data will be controlled via GWN Web Portal User Profiles. User Profiles should be periodically reviewed.

A black list of radio identification numbers can be provided to the GWN Service Desk. For example, QPS have a black list of their secret operations radios that they do not want other QPS personnel to have access to.

5.9 Radio network busiesDuring times of very high traffic, if a P25 trunked radio site runs out of capacity, a busy queue is created. The radio user who PTTs when the site has run out of capacity will receive a busy tone, which indicates that their call has been placed in the busy queue. When capacity becomes available they will be assigned a channel and receive the channel grant tone. This scenario is generically referred to as a busy, or busies.

State Beneficiaries should ensure that personnel are well trained in the concept of busies, including ingress and egress busies and fast start / late entry conditions. Personnel should understand that busies are a normal part of the operation of a P25 trunked radio networks, like the GWN, and not a sign of failure in the network.

Personnel should report any unusual or extended busies to their State Beneficiary Representatives, and Representatives should pass these reports to GWN Contract Directorate via the Contract Directorate and State Beneficiary monthly meetings.

The GWN Contract Directorate will review busies monthly and investigate any abnormal trends.

5.10 Connecting unapproved devicesState Beneficiaries and their personnel are not to connect any unapproved devices to the GWN Facility in any fashion. This includes, but not limited to, the following: provisioning of jumpering on MDF / Krone Strips connecting devices to any GWN Facility network port connecting devices via the 4 wire interface of a Mobile Radio connecting any rebroadcasting device connecting devices to Conventional Channel Gateway (CCGW) connecting approved devices but in a not as intended fashion

Only approved devices, being used as approved, are to be connected to the GWN Facility.

State Beneficiaries are to self-report any instances of connecting unapproved devices and the remediation that was performed to ensure no reoccurrence in the future.

5.10.1 Rebroadcasting of GWN radiocommunications

Before the Queensland Public Safety Agencies (PSAs) became State Beneficiaries of the GWN, their legacy radio channels could be listened to via the Internet. Due to legacy radio networks not being encrypted, members of the public could rebroadcast the radio channel via the Internet with minimal expense or expertise. Some PSAs report listening to their



legacy radio channels via a third party application on their smart phones for operational awareness.

As all GWN traffic is currently encrypted, members of the public are not be able to listen in to GWN radiocommunications and hence not be able to rebroadcast GWN traffic.

There is a potential risk that State Beneficiary personnel, with GWN subscriber equipment, could create an extension of GWN voice circuits to rebroadcast via the Internet. Eg. Radio over IP.

If a State Beneficiary has an operational need to rebroadcast their radio talkgroups via an IP network, there are solutions that can be implemented that provide secure communications. That is, these solutions only allow authorised users to listen while still maintaining security.

Contact the GWN Contract Directorate for more information if required.

State Beneficiaries are to ensure personnel do not use subscriber equipment for purposes other than their intended use.

5.11 Lost, misplaced or stolen subscriber equipmentIn the event of lost, stolen or damaged subscriber equipment, personnel should immediately notify the GWN Service Desk to inhibit the radio and arrange replacement equipment. Even in the scenario where a radio is genuinely misplaced and not lost, the radio should be immediately inhibited by contacting the GWN Service Desk, as it can quickly be uninhibited if necessary.

The term subscriber equipment includes all accessories provided with the radio. For example, QPS and QAS Digital Portable Radio Pack includes a remote speaker microphone, a receive only earpiece and a carry case. In the case of mobile radios installed in vehicles, the antenna is considered an accessory. If any of the accessories are misplaced, contact the GWN Service Desk to arrange replacement.

The GWN Contractor has Service Level Agreements (SLA) on the timeframes to provide replacement subscriber equipment as part of Incident Management processes. For further details refer to Schedule 3B of the GWN Services Agreement.

Refer to the GWN Lost, Stolen or Damaged Subscriber Process and GWN Portable and Consumable Replacement Process for further details on the Contractual and financial implications.

State Beneficiaries are to ensure personnel are aware of how to respond and who to contact when subscriber equipment, including accessories, are lost, misplaced or stolen. State Beneficiary Representatives are to escalate any issues relating to lost or stolen equipment to the GWN Contract Directorate if unsure of what to do.

5.12 Damaged or faulty subscriber equipmentUnder the GWN Services Agreement, subscriber equipment is owned and maintained by the GWN Contractor.

In the event of damaged or faulty subscriber equipment, personnel should immediately notify the GWN Service Desk to arrange for replacement equipment.

As mentioned previously, the term subscriber equipment includes all accessories provided with the radio. Some accessories are considered consumables, including vehicle antennas, under the GWN Contract.



Refer to the GWN Lost, Stolen or Damaged Subscriber Process and Consumable Replacement Process for further details on the Contractual and financial implications.

State Beneficiaries are to ensure personnel are aware of how to respond and who to contact when subscriber equipment, including accessories, are damaged or faulty. State Beneficiary Representatives are to escalate any issues relating to damaged or faulty equipment to the GWN Contract Directorate if unsure of what to do.

5.13 Subscriber equipment transport or maintenanceWhen subscriber equipment is not in the possession of State Beneficiary personnel or a third party who is authorised to use the subscriber equipment for official use, the subscriber equipment should be inhibited.

For example, when a GWN equipped vehicle is sent for a mechanical service, the radio should be inhibited before being sent for service to ensure there is no opportunity for eaves dropping or misuse. A similar example is if a cache of portable radios being transported by a courier service.

Note: There have been instances of radios being transported and accidentally being turned on and dragging busy dispatch talkgroup traffic.

State Beneficiaries should develop their internal processes to identify situations where radios should be inhibited, and which personnel have authorisation to request a radio inhibit or uninhibit.

5.14 Identifying subscriber equipment usersState Beneficiaries decide how they should assign subscriber equipment to their personnel. The State Beneficiary should ensure that at all times it can be determined which personnel has which radio from a radio ID or radio alias. If a query is received with a radio ID and time, the State Beneficiary must be able to identify the personnel in possession of that radio at that time.

For the purposes of this Guide, dispatch consoles are considered subscriber equipment and hence the identification of users also extends to users of consoles in State Beneficiaries Communication Centres.

State Beneficiaries are to implement training, processes and to ensure users of all subscriber equipment can be identified at all times.

5.15 High usage subscribersState Beneficiaries should review high usage subscriber equipment to ensure no inappropriate use is occurring.

The GWN Contract Directorate may periodically review the numbers of high usage subscribers and request State Beneficiaries to participate in such reviews.

The GWN Contractor produces a monthly R19 Scheduled Periodic Monthly Report which contains the Agency Terminal Usage Summary report which can be easily used by State Beneficiaries to review high usage subscribers. This report is available on the GWN Web Portal 10 business days after the start of the new month.



5.16 Subscriber equipment cachesIf a State Beneficiary has subscriber equipment caches, they need to periodically turn on these radios. This is to ensure they are functional, allow for any over the air updates like codeplugs or encryption keys.

As per section 4.10, if caches radios are to be reprogrammed, the cache should be delivered to Service Centre to be reprogrammed. OTAP is not to be used for reprogramming subscriber equipment Caches.

5.17 Third party subscriber equipment usageState Beneficiaries may decide that for operational reasons to provide subscriber equipment to third party organisations on a temporary basis for reasons of interoperability.

The third party radio users effectively become personnel of the State Beneficiary for the purposes of this Guide. The State Beneficiary will be held accountable for the actions of third parties relating to the use of the GWN.

Refer to GWN External Agency Terminal Policy for further details.

5.18 Console talkgroup patchingDispatch Consoles provide Patching functionality which effectively combines or patches two or more talkgroups into one. Patching can also be used to patch unencrypted legacy network channels to encrypted GWN talkgroups. The patching of encrypted and unencrypted channels / talkgroups allows encrypted GWN traffic to be rebroadcasted unencrypted over a legacy network, effectively removing the encryption.

State Beneficiaries can decide if they will allow patching of encrypted and unencrypted traffic, but it is not recommended.

Currently State Beneficiaries use a ‘supervisor’ dispatch console position to perform permanent or long term patching.

5.19 Subscriber equipment asset identificationEach subscriber equipment item included in GWN Subscriber Equipment packs will have a GWN asset identification (ID) tag or sticker. There are some exceptions with items that are too small, for example, Bluetooth earpieces.

These asset ID’s are not to be tampered with. If an asset ID has become loose, lost, illegible or damaged please contact the GWN Service Desk and raise a Service Request to get the asset ID replaced.

5.20 Radiocommunications in communication centresRadios should not be used within Communications Centres. All radiocommunications inside of Communication Centres should be done via Dispatch Consoles. This is for the reasons of avoiding unnecessary radio traffic and the poor performance of radios in vicinity of a plethora of electrical and electronic equipment.

5.21 CallsignsAs per ACMA Guidelines for Land Mobile Licenses, “Callsigns should be used for all on-air communications”. Due to the GWN Facility being a digital private network, formal callsigns are not required.



All State Beneficiaries should create their own radio identification naming conventions. These naming conventions are only required to be understandable by radio users within their organisation, and State Beneficiaries train their personnel on when to transmit this identification.
