Executive summary

This engineering report accompanies, and is intended to read with, documentation related to the draft Television Licence Area Plan (TLAP) for the Adelaide TV1 Licence Area. It provides background explanations for the proposed channel block identifications and channel allotments for broadcast sites and other relevant types of sites such as retransmission sites within the Adelaide TV1 Licence Area.

The proposed channel allotments are discussed in detail in section 2 of the report, and are summarised in the table following this executive summary. The proposed block identifications and channel allotments follow the restack principles unless specifically noted.

Section 3 of the report discusses implementation sequencing constraints that may need to be captured as events or circumstances in the draft TLAP or as licence conditions. However, the determination of restack ‘timing windows’ is not covered in this report. It is considered separately in the discussion paper for metropolitan licence area draft TLAPs that is being released together with this engineering report.

Note: Revision 1 of this Engineering Report corrects an error in section 2.2.1 were the proposed interim channel for CTS was incorrectly indicated as channel 28 (it is correctly shown as channel 33 in other parts of the Report). In addition, a number of editorial/style corrections were also made.

Proposed channel allotmentsThe table below summarises the channel allotments proposed in this engineering report. These allotments will be included in the related draft TLAP instrument.

Sites shown in rows with grey shading have all retransmission services. These services are not expected to be included in the TLAP instrument. However, they have been taken into account in channel planning for the TLAP.

Channels that are allotted in the TLAP for currently operating services that will be restacked are identified by ( ).

1 Introduction1.1 ScopeThis report should be read in conjunction with the draft TLAP for Adelaide, the associated discussion/explanatory papers and the related planning documents. These contain the detailed transmitter specifications consistent with the parameters assumed in conducting predictions of signal levels as part of the planning process.

The legislative and regulatory background of the relevant TLAP is discussed in the metropolitan draft TLAP discussion paper.

The Adelaide TV1 licence area covers metropolitan Adelaide and surrounding areas including the Adelaide Hills and the Fleurieu Peninsula. The main high-power transmission site in this area is Mt Lofty.

The digital switchover timetable set the Adelaide licence area to switchover on 2 April 2013. Surrounding areas in the Spencer Gulf, Riverland and South East/Mt Gambier licence areas completed switchover on 15 December 2010. This engineering report provides supporting engineering information to explain the choice of channels at sites to be included in the Adelaide TLAP. To provide a complete view of the constraints influencing channel block selection, the scope of this engineering report also includes sites used to provide retransmission services (both those operated by TX Australia, and those operated by councils or other community organisations).

The report also analyses the constraints affecting the sequencing of the move to final restack channels but the determination of the timing window within which the transition to final digital channels must occur is covered in the discussion paper for metropolitan licence area draft TLAPs.

1.2 Channel planning principlesThe planning principles that underpin the identification of blocks and allotment of channels have been the subject of extensive consultation/discussion at the Restack Planning Advisory Group (RPAG) and then a formal public consultation. Feedback on the proposed restack objectives was broadly positive and supportive of the proposed planning objectives. In its analyses that led to the decision to incorporate the block planning approach in its Planning Principles, the ACMA undertook an extensive comparative analysis of two alternative planning approaches and eventually adopted the block approach over the alternative minimum moves approach.

The development of the overall restack channel plan followed a top-down approach. That is to say, high-power sites and other sites serving large populations were considered first and the most suitable channel blocks for those key sites were identified. After that, more detailed region-by-region analyses were performed to identify channel blocks for the repeater sites in each region.

acma | 3

1.3 Channel block identifications for the Adelaide licence area

The identified channel block for the high-power Adelaide services was fixed as Block A by the ministerial direction to the ACMA.

Within the RPAG a collaborative process was undertaken to develop an indicative channel plan for ‘key sites’ around Australia. That process concluded that the block identifications for major surrounding regional transmitter sites around Adelaide should be: Renmark/Loxton (Block B), South East (Block B) and Spencer Gulf North (Block D). In addition, in consultation with industry, channel blocks for lower-power sites in regional South Australia were identified. After public consultation, those channel allotments were codified in TLAPs for the Mount Gambier/South East, Spencer Gulf and Riverland licence areas.

The block allocations for sites in regional South Australia licence areas strongly influence the block identifications of several of the repeater sites in the Adelaide licence area. Further details of the block identification and channel allotment for all sites in the Adelaide licence area are discussed in section 2.

Section 3 uses those proposed block identifications, and knowledge of interference compatibility constraints to determine limitations or conditions that could apply to the sequence in which the restack is implemented.

Appendix A1 provides the ACMA’s planning principles.

Appendix A2 provides a channel chart that summarises the proposed channel allotments as well as current analog (where applicable) and digital channels at each site.

Appendix A3 provides colour-coded maps that illustrate the channel block identified for each transmitter site together with an indication of its expected coverage.

Appendix A4 provides a service-by-service listing of constraints on restacking each service.

1.4 Consultation The ACMA distributed a draft of this engineering report prior to the RPAG Working Group meeting on 30 May 2012 and discussed the channel planning proposals contained in the draft at that meeting.

1.5 TerminologyBlock identification and channel allotmentsTo align with terminology being adopted in TLAP instruments, this report uses the terms ‘identify’ or identification’ when referring to the proposed block of channels to be used to serve a particular area. The channels of the identified channel block are specified in the TLAP. The term ‘allotment’ is used in the TLAP and in this engineering report in relation to which channel is to be used by which broadcaster. Some channels will remain unallotted in the TLAP and may be available for future allotment to a new service or be made available for retransmission services operated by third parties.

Call sign for ABC servicesThe ABC has traditionally been given a unique call sign for services from main sites and off-air fed translators and a generic state-based call sign for the main metropolitan service and satellite fed services. For example, the ABC service at Adelaide has the call sign ABS. This convention has not been rigorously applied over the years and this can lead to confusion. For the purposes of consistency, in this engineering report and draft TLAP documents, the call sign ABC has been used for all ABC services.

1.6 Transmitter specificationsDetailed transmitter specifications for each service at each site are included in separate planning data. The planning data will become a ‘living document’ that should quite closely reflect the actual operating conditions of all services within the planning area covered by the TLAP. It is intended that the planning data will be revised from time to time as better information, or changes to transmitter specifications, are advised to the ACMA. Generally those specifications follow existing DCP technical specifications (except for channel changes). 2

2 Block identification and channel allotment proposals

2.1 BackgroundThis section of the engineering report describes how the proposed channel blocks were identified for each area and explains the proposed channel allotments within each identified block. In addition to the normal consideration of avoiding or minimising predicted interference between services, channel allotments have been made in accordance with the ACMA’s planning principles unless specifically noted in the discussion in this section. The planning principles are reproduced in Appendix A1.

Selection of channel blocks and channel allotments has been done in accordance with Principles 4 and 5 in all cases. In the selection of channel blocks the ACMA has been guided by the need to avoid interference between services and by Principle 7. Discussion on the rationale for particular block selections is included on a site-by-site basis in sections 2.2 and 2.3. Similarly the channel allotments within each identified block generally follow Principle 6, but individual issues are discussed in sections 2.2 to 2.3.

In addition to the site-by-site discussion in this section, the channel allocation proposals have also been summarised in a consolidated channel chart (that also shows current analog and digital channels) in Appendix A2.

2.2 High-power sites2.2.1 Adelaide (Mt Lofty) Block AAdelaide (Mt Lofty) is the main high-power transmission site serving the Adelaide Switchover Area. At Mt Lofty three transmission sites may transmit digital services; however, those sites are considered to be effectively co-sited.

The identified channel block for the high-power metropolitan services in Adelaide is Block A. Proposed channel allotments for Adelaide follow Principle 6 and are shown in Table 2.1.

The Adelaide CTS30 service currently operates under a trial licence and is licensed until 30 June 2013. Arrangements beyond that date are subject to future government decisions. However, continued operation of CTS on channel 30 will directly delay the restack of Renmark/Loxton. In turn Renmark/Loxton constrains the restack of a further 6 sites including Underbool and Robinvale in the Mildura/Sunraysia TV1 Licence Area. To allow these potential delays to be avoided, an option to move the CTS trial service to channel 33 after the Adelaide SBS33 digital service vacates channel 33 has been provided.

2.3 Adelaide licence area repeater sitesTable 2.1 shows the proposed block identifications and channel allotments for repeater sites in the Adelaide switchover region.

Block identifications have not been made for the following sites: Cudlee Creek, Golden Grove, Hallett Cove, Kingscote, Peterhead and Truro Grove. If channels for these sites are required in future, they should fit within the framework provided in Table 2.1.

2.3.1 Overview discussionThe configuration shown in Table 2.1 evolved from discussions between the ACMA and regional and metropolitan broadcasters that developed a broad framework for regional SA and Adelaide metropolitan repeater block allotments. That initial framework was refined following detailed compatibility studies performed by the ACMA.

In general the repeater block identifications for sites in the northern parts of Adelaide licence area did not use Block D in order to avoid incompatibility with Spencer Gulf North high-power services. Similarly repeater block identifications for sites on eastern side of the Adelaide licence area did not use Block B so that incompatibility with Renmark/Loxton high-power services was avoided. Additionally, detailed investigations were required to find a compatible channel block for the proposed Maitland repeater, and resulted in some adjustments to the initial framework.

2.3.2 Maitland Block EMaitland services need to avoid Spencer Gulf North services on Block D, Cowell services on Block C and should desirably avoid Tumby Bay services on Block B. It is also desirable, if practical, for Maitland services to avoid co-channelling with Angaston, Myponga and Normanville services. Therefore, Block E is the identified channel block for use at Maitland.

Detailed compatibility studies indicated that careful engineering is required to ensure compatibility between Maitland and several other sites that may use Block E. The outcome of those studies was that the polarisation of Maitland has been set to be vertical, the antenna pattern HRP was optimised to minimise interference to Port Lincoln, and channel block selections at sites in the Normanville/Carrickalinga/ Yankalilla group have been chosen to minimise predicted interference to and from Maitland.

The proposed channel allotments for Maitland are SAS46, NWS47, ADS48, UA49, SBS50 and ABC51. This allows the NWS, SBS and ABC services to commence on the post-restack channels. The proposed channel allotment order has been set by the pre-restack channels preferred by TX Australia (which will hold the licences of all these services).

2.3.3 Craigmore/Hillbank Block CThe Craigmore/Hillbank services have been planned on the basis of protection of locations where the Craigmore/Hillbank services provide a greater margin above threshold than other Adelaide licence area services and where the received field strength exceeds the ‘suburban’ level.

Craigmore/Hillbank services need to avoid Spencer Gulf North services on Block D, and should not be operated co-channel with Elizabeth South services (unless operated in an SFN). It is also desirable, but arguably not essential, that co-channel operation with Maitland services (proposed for Block E) is avoided since some minor interference is predicted to the fringe of the Craigmore/Hillbank coverage even after masking out areas that have alternative coverage from other Adelaide licence area services. Studies also indicated that a small part of the Craigmore/Hillbank coverage may be subject to interference from Adelaide Foothills, so it may be desirable (though perhaps not essential) to operate Craigmore/Hillbank and Adelaide Foothills in an SFN.

Given that all five currently operating Craigmore/Hillbank services are in Block C, it is proposed that Block C be retained to avoid changes to operating services.

8 | acma

The proposed channel allotments for Craigmore/Hillbank follow Principle 6 and maintain the currently operating channel allotments and are SBS34, SAS35, NWS36, ADS37, UA38 and ABC39.

2.3.4 Elizabeth South Block BThe Elizabeth South broadcast site currently only provides ABC and SBS services. Commercial broadcasters have not indicated any interest in establishing services at this site. Since the Craigmore/Hillbank site (which overlaps much of the Elizabeth South coverage) has been established it is unclear if the Elizabeth South services need to continue. National broadcasters are invited to review whether any viewers rely on these services before proposing to implement the restack channels proposed in this report.

The Elizabeth South services have been planned on the basis of protection of locations where the Elizabeth South services provide a greater margin above threshold than other Adelaide licence area services and where the received field strength exceeds the ‘suburban’ level.

Elizabeth South services need to avoid Spencer Gulf North services on Block D and should not be operated co-channel with Maitland services which has been proposed to operate on Block E. Also, Elizabeth South uses a 2-sided PVP panel array transmitting antenna which may need to be replaced if Block B is adopted and the restack of Elizabeth South services proceeds.

Craigmore/Hillbank services should desirably not be operated co-channel with Elizabeth South services (unless operated in an SFN). Studies found that Elizabeth South services would not receive co-channel interference from Adelaide Foothills services, but in the reverse direction co-channel interference is predicted unless the services at both sites are operated in an SFN.

After weighing these somewhat competing considerations, although the use of Block B may require transmitting antenna changes, Block B is proposed because it may avoid the need for SFNs for all services between Adelaide Foothills and Craigmore/Hillbank and because it will certainly avoid the need for a three site SFN for national services.

The proposed channel allotments at Elizabeth South are SBS29 and ABC32 as these are the only currently available unconstrained Block B channels.

2.3.5 Adelaide Foothills Block CThe Adelaide Foothills services have been planned on the basis of protection of locations where the Adelaide Foothills services provide a greater margin above threshold than other Adelaide licence area services and where the received field strength exceeds the ‘suburban’ level.

Adelaide Foothills services need to avoid Spencer Gulf North services on Block D. Adelaide Foothills services are not compatible with co-channel Maitland services that have been proposed for Block E. (Adelaide Foothills analog services are also not compatible with Maitland digital services). Block B should also be avoided since current Adelaide Foothills viewer antennas may not have Band IV capability. Therefore, the identified channel block for Adelaide Foothills is Block C. This places both Adelaide Foothills and Craigmore/Hillbank on Block C; however, prediction studies indicate that potential co-channel interference between Craigmore/Hillbank and Adelaide Foothills is limited to locations that are predicted to receive stronger signals from Mt Lofty.

acma | 9

The proposed channel allotments for Adelaide Foothills have been aligned with the channel order of the operating Craigmore/Hillbank Block C services. The proposed channel allotments at Adelaide Foothills are SBS34, SAS35, NSW36, ADS37, UA38 and ABC39.

2.3.6 Lyndoch Block CThe Lyndoch services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Lyndoch services need to avoid Renmark/Loxton on Block B and Spencer Gulf North services on Block D. It is desirable that Lyndoch services not be operated co-channel with Maitland services (proposed for Block E) due to some minor potential interference to areas of weak signal within the Lyndoch suburban coverage contour. Therefore, it is proposed that Lyndoch should operate on Block C.

The proposed channel allotments for Lyndoch have been aligned with the channel order of the operating Craigmore/Hillbank Block C services. The proposed channel allotments at Lyndoch are SBS34, SAS35, NSW36, ADS37, UA38 and ABC39.

2.3.7 Gumeracha Block EThe Gumeracha services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Gumeracha services need to avoid Renmark/Loxton on Block B and Spencer Gulf North services on Block D. Blocks C and E are potentially available. However, Block C is not preferred because the currently operating Renmark/Loxton RTS35 and ABC39 services would prevent Gumeracha digital services commencing on final channels. Therefore, it is proposed that Block E should be identified for use at Gumeracha.

The proposed channel allotments for Gumeracha are SAS46, NWS47, ADS48, ABC49, SBS50 and UA51. This follows the channel allotment order requested by TX Australia (which will hold the licences of all these services).

Note: After analysis of a proposal from metropolitan commercial broadcasters it has been concluded to increase the ERP of the proposed digital services at this site from 5W ERP to 50W ERP. Note that the digital services will be implemented at a slightly different site with an increased antenna height than that which is used for the currently operating analog services.

2.3.8 Angaston Block CThe Angaston services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Angaston services need to avoid Renmark/Loxton on Block B and Spencer Gulf North services on Block D. It is desirable that Angaston services not be operated co-channel with Maitland services due to some potential interference to fringes of the Angaston coverage. Since it is proposed that Block E should be used at Maitland, it is proposed that Angaston should operate on Block C.

The proposed channel allotments for Angaston have been aligned with the channel order of the operating Craigmore/Hillbank Block C services. The proposed channel allotments at Angaston are SBS34, SAS35, NSW36, ADS37, UA38 and ABC39.

10 | acma

Eudunda Block CThe Eudunda services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Eudunda services need to avoid Renmark/Loxton on Block B, Spencer Gulf North services on Block D and Waikerie services on Block E. Therefore, it is proposed that Eudunda should operate on Block C.

The proposed channel allotments for Eudunda have been aligned with the channel order of the operating Craigmore/Hillbank Block C services. The proposed channel allotments at Eudunda are SBS34, SAS35, NSW36, ADS37, UA38 and ABC39.

2.3.9 Carrickalinga Block EThe Carrickalinga services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Carrickalinga services need to avoid Spencer Gulf North services on Block D, and should not be operated co-channel with Normanville services (unless in an SFN). Current Carrickalinga analog channels are above channel 52, so use of Block B is not recommended. Therefore, Block E is proposed at Carrickalinga.

The proposed Carrickalinga channel allotments are SAS46, NWS47, ADS48, ABC49, SBS50 and UA51. This follows the channel allotment order requested by TX Australia (which will hold the licences of all these services).

2.3.10 Normanville Block CThe Normanville services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Normanville services should desirably avoid Renmark/Loxton services on Block B. Normanville services should not be operated co-channel with Carrickalinga or Yankalilla services. It is also desirable, if practical, to avoid Spencer Gulf North (Block D) and Maitland (Block E) due to minor interference to the fringes of the Normanville coverage. Therefore, Block C is the preferred block identification for Normanville.

The proposed channel allotments for Normanville follow those of other Block C sites in the Adelaide licence area with the exception that, because the currently operating ABC38 Spencer Gulf service is not a constraint at this site, channel 34 can be avoided. (Although not essential, it is desirable to avoid using channel 34 for the SBS service so that an adjacent channel off-air input with the currently operating Adelaide SBS33 digital service is avoided). However, a simple swap between SBS34 and SBS38 is not possible since that would create an N+5 input feed issue. The proposed channel allotments at Normanville are UA34, SAS35, NSW36, ADS37, ABC38 and SBS39.

Note: After analysis of a proposal from metropolitan commercial broadcasters it has been concluded to increase the ERP of the proposed digital services at this site from 10 W ERP to 40 W ERP.

2.3.11 Yankalilla Block DThe Yankalilla services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

acma | 11

Yankalilla services must not operate co-channel with Normanville services (unless operated in an SFN). No other incompatibilities with other Adelaide licence area repeaters or surrounding regional area services have been identified. However, studies show minor interference from Maitland (Block E) and Spencer Gulf North (Block D). The minor predicted interference from Spencer Gulf North is predicted to affect areas of weak signal to the south of Yankalilla that may in fact be better served by Normanville.

Current Yankalilla analog channels are above channel 52, so use of Block B is not recommended. On balance it is proposed to operate Yankalilla on Block D.The proposed channel allotments for all Adelaide licence area Block D sites follow a common arrangement that avoids Renmark/Loxton SBS40. The proposed channel allotments at Yankalilla are UA40, SBS41, ABC42, SAS43, NWS44 and ADS45.

Note: After analysis of a proposal from metropolitan commercial broadcasters it has been concluded to increase the ERP of the proposed digital services at this site from 5 W ERP to 20 W ERP.

2.3.12 Myponga Block DThe Myponga services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

No incompatibilities with other Adelaide licence area repeater or surrounding regional area services have been identified, however, if practical it may be desirable not to co-channel with Maitland services on Block E (though the potentially affected area is expected to be better served from Mt Lofty). It is also desirable to avoid Block B due to potential frequency limitations of the PVP panel transmitting antenna and viewer receiving antennas.

The proposed channel allotments for all Adelaide licence area Block D sites follow a common arrangement that avoids Renmark/Loxton SBS40. The proposed channel allotments at Myponga are UA40, SBS41, ABC42, SAS43, NWS44 and ADS45.

2.3.13 Cape Jervis Block DThe Cape Jervis services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

No incompatibilities with other Adelaide licence area repeater or surrounding regional area services have been identified. It is also desirable to avoid Block B due to potential frequency limitations of the PVP panel transmitting antenna and viewer receiving antennas.

The proposed channel allotments for all Adelaide licence area Block D sites follow a common arrangement that avoids Renmark/Loxton SBS40. The proposed channel allotments at Cape Jervis are UA40, SBS41, ABC42, SAS43, NWS44 and ADS45.

2.3.14 Strathalbyn Block DThe Strathalbyn services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Strathalbyn services need to avoid Renmark/Loxton on Block B. It is also desirable that Strathalbyn services avoid Victor Harbor services on Block C. So, Blocks D and E are potentially available. Block D is preferred since it is lower in frequency.

12 | acma

The proposed channel allotments for all Adelaide licence area Block D sites follow a common arrangement that avoids Renmark/Loxton SBS40. The proposed channel allotments at Strathalbyn are UA40, SBS41, ABC42, SAS43, NWS44 and ADS45.

2.3.15 Victor Harbor Block CThe Victor Harbor services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Victor Harbor services should desirably avoid Renmark/Loxton services on Block B. No incompatibilities with other Adelaide licence area repeaters have been identified. The current antenna is understood to comprise PVP panels and should not constrain choice of channel blocks. Blocks C, D or E are potentially available. Block C is preferred since it is lower in frequency.

Studies found that co-channel Block C operation at Victor Harbor is compatible with Adelaide Foothills and Craigmore/Hillbank.

The proposed channel allotments at Victor Harbor have been aligned with other Block C sites in the Adelaide licence area and are: SBS34, SAS35, NSW36, ADS37, UA38 and ABC39.

2.3.16 Mannum Block DThe Mannum services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Mannum services need to avoid Renmark/Loxton services on Block B. No other constraints due to Adelaide licence area repeater sites have been identified. The current transmitting antenna is an RFS PHP panel. So, Blocks C, D or E are potentially available. However, Block C is not preferred since the currently operating Renmark/Loxton RTS35 and ABC39 services would prevent commencement of Mannum digital services on final channels. Of the remaining blocks, Block D is proposed since it is lower in frequency.

The proposed channel allotments for all Adelaide licence area Block D sites follow a common arrangement that avoids Renmark/Loxton SBS40. The proposed channel allotments at Mannum are UA40, SBS41, ABC42, SAS43, NWS44 and ADS45.

2.3.17 Swan Reach Block CThe Swan Reach services have been planned on the basis of protection of locations where the received field strength exceeds the ‘suburban’ level.

Swan Reach services need to avoid Renmark/Loxton on Block B and should desirably avoid Spencer Gulf North services on Block D. It would also be desirable to avoid Waikerie on Block E. Therefore, it is proposed to identify Block C for use at Swan Reach.

The proposed channel allotments for Swan Reach have been aligned with the channel order of the operating Craigmore/Hillbank Block C services. The proposed channel allotments at Swan Reach are SBS34, SAS35, NSW36, ADS37, UA38 and ABC39.

3 Implementation/sequencing considerations

This section of the report introduces the concept of TLAP timing windows and discusses implementation sequencing constraints that may need to be captured as events or circumstances in the draft TLAP or as licence conditions. The determination of restack ‘timing windows’ is not covered in this report. It is discussed separately in the discussion paper for metropolitan licence area TLAPs that is being released with this engineering report.

3.1 TLAP timing windowsThe TLAP instrument for Adelaide will specify the period for which each channel is allotted. For a service that must restack, the TLAP would show two entries—one for the current channel allotment and a second for the final (post-restack) channel allotment. By overlapping the periods during which the current and final (or post-restack) channels are allotted, a ‘timing window’ is created within which broadcasters can schedule the actual date for the restack of each site. For services not restacking, only one channel allotment is shown in the TLAP because the pre- and post-restack channels will be the same.

The timing window concept is being used as it is not practical to define precise restack dates in the TLAP. This is because any slippage due to equipment delivery or delays due to weather events, or opportunistic advancement of some work when other work is delayed, would require the TLAP to be varied. Broadcasters and the restack Program Implementation Manager will need to make adequate contingency allowances in their project planning to ensure that any applicable planning permits are obtained, and site works, equipment deliveries and the actual restack for each site occurs before the end of the timing window.

Additionally, the restack at each site will need to be coordinated between broadcasters to avoid (or minimise) any need for viewers to retune their television(s) multiple times during a restack timing window.

3.2 Constraints on the restacking of sitesAn analysis showing which sites need to be restacked or switched off before other sites can be restacked has been performed. The results of that analysis are summarised in Table A4.1 in Appendix A4, where current constraints (if any) are shown for each service at each site.

To provide a complete understanding of opportunities for the restack of Adelaide area sites ahead of the Adelaide switchover, analog constraints for Adelaide area sites have been included.

Of the 18 sites considered in this report, 12 can operate on final post-restack channels at any time within the restack timing window for the Adelaide licence area.3 These are summarised in Table 3.1. Table 3.1 shows two categories of sites that will not impose constraints on the timing and sequencing of the restack.

3.3 Implementation considerations

As shown in Table 3.2 the restack of several Adelaide licence area services is constrained by surrounding regional licence area services. In fact, as explained in the following sub-sections, some of these are actually chains of constraints. So a key observation is that the planning the sequencing of Adelaide licence area restack work needs to be integrated with planning for the sequencing of the surrounding Renmark/Loxton and Spencer Gulf areas.

3.3.1 Constraints due to Renmark/LoxtonSome of the Renmark/Loxton constraints noted above are in turn constrained by Adelaide licence area services. The earlier regional South Australia engineering report identified some interrelated constraints between Adelaide and Renmark/Loxton services.

The Renmark/Loxton RTS35 service cannot restack to its final RTS30 channel until the Adelaide CTS30 digital service vacates channel 30.

3.3.2 Spencer Gulf region constraintsThe earlier regional South Australia engineering report identified an interrelated chain of constraints between a number of Adelaide and Spencer Gulf licence area services.

The Spencer Gulf North ABC38 digital service cannot restack to its final ABC43 channel until the Adelaide Foothills SBS43 analog service vacates channel 43 (at Adelaide ASO in 2 April 2013) and until Tumby Bay SBS43 digital service vacates channel 43. This in turn depends on Tumby Bay SBS43 moving to channel 28 which cannot occur until Adelaide SBS28 analog switches off (at Adelaide ASO in 2 April 2013).

Cowell GTS48 cannot move to its final GTS34 channel until Tumby Bay GTS34 restacks to channel 33. But this is constrained by the operating Adelaide SBS33 digital service which cannot switch-off until the completion of any Adelaide SBS digital-digital simulcast period. (Note: Cowell and Tumby Bay are within the second timing window for Spencer Gulf sites which was determined as 1 January 2014 to 30 September 2014; however, it is now proposed to be varied to 3 April 2013 to 30 September 2014).

Note: In earlier studies described in the regional South Australia engineering report the Wudinna IMP39 analog service was identified as a potential constraint on the restack of the Cowell SBS61 digital service to channel 39. However, more detailed studies have found that this is not a constraint.

Appendix A1—Planning principlesNote: the wording of principles below has been adjusted to align with the terminology adopted for TLAPs.

Principle 1: Replan digital television services to use VHF channels 6–12 and UHF channels 28–51.

Principle 2: Create a digital radio sub-band, comprising VHF television channels 9 and 9A, that is clear of digital television in metropolitan and regional licence areas. Where practicable, also avoid planning new services on these channels in remote licence areas.

Principle 3: Plan for six digital channels at each transmission site, except fori)  licence area overlaps where two sets of three commercial services will require channels (a total of nine channels)ii)  where broadcasters operate from different sites but cover the same area.

Principles 4–6 define the essential elements of the block planning approach.

Principle 4: Plan channels so that viewers in metropolitan and regional licence areas can receive all services using a single band antenna (i.e., plan all channels in either the VHF or UHF band). Consider the benefit of single band operation in other areas on a case-by-case basis. The current polarisation of the existing transmissions in a particular band at each transmission site is to be maintained.

Principle 5: Plan all six services on channels within defined blocks of channels as follows:

Block A: 6, 7, 8, 10, 11 and 12*Block B: 28, 29, 30, 31, 32 and 33Block C: 34, 35, 36, 37, 38 and 39Block D: 40, 41, 42, 43, 44 and 45Block E: 46, 47, 48, 49, 50, and 51.* Channels 9 and 9A may be used for digital TV in some remote areas.

Principle 6: Allot channels within a block as follows:

VHF: Existing VHF services to retain current channels unless they have to move to clear channels 9 and 9A under principle 2. New or changed channel allotments do not need to follow any particular order, except in all metropolitan areas where SBS should move to channel 7. Where it is possible without moving existing services, channel 10 should be the unallotted channel to align with the metropolitan area unallotted channel.

UHF: Channel allotments should be made after considering and balancing a number of objectives including: avoiding off-air input issues (adjacent channel and N+5) avoiding changes to existing services within the block using the unallotted channel to remove restack timing constraints and manage

band edge interference potential.

If none of the above issues apply, UHF channels should be allotted in the following order: SBS, ABC, Seven (or affiliate), Nine (or affiliate), Ten (or affiliate), unallotted.

Principle 7: In selecting the channel block for a transmission site:

18 | acma

Consider the channels used by existing digital services and any information available on the operating frequency range of broadcaster transmission equipment.

Avoid use of a block outside the likely bandwidth of viewer antennas. In particular, avoid Block B where there is no current or past use of UHF Band IV channels. Where this cannot be avoided, minimise the total population affected.

Wherever sites utilise UHF channel blocks, attempt to place high-power services on lower UHF channel blocks.

Principle 8: Break up wide area single frequency networks (SFNs) known to have associated reception problems and minimise use of new SFNs where possible.

Principle 9: Plan on the basis of broadcasters using the DVB-T standard with transmission parameters of 8k, 64QAM, 2/3 forward error correction (FEC) and 1/16 guard interval.

The co-channel protection ratio used for planning will be: 20 dB

The minimum median field strengths used for planning will be:

Minimum median field strengths for digital television planning (dBµV/m)

VHF (Block A)(174–230 MHz)

UHF (Blocks B and C)(526–610 MHz)

UHF (Blocks D and E)(610–694 MHz)

Rural Suburban Urban Rural Suburban Urban Rural Suburban Urban

Minimum median field strength (dBuV/m)

44 57 66 50 63 71 54 67 74

Consistent with the reconfirmation of the existing technical planning parameters, the assumed transmission parameters include an FEC of 2/3. Also consistent with the reconfirmation of the current minimum median field strengths and 2/3 FEC, a co-channel protection ratio of 20 dB will also continue to be used.

However, recognising the proposal to break up wide area SFNs in principle 8, a 1/16 guard interval has been adopted.

Principle 10: Equalise transmissions across all broadcasters as far as practicable through planning on the basis of equal ERP levels, identical antenna patterns, closely sited transmitters and all broadcasters having the same SFN arrangement.

Principle 11: Determine the timing constraints on channel availability and specify a minimum window of six months, where practicable, when both the current digital and the final digital channels are available. When all sites and timing windows are considered together, they should result in the digital dividend channels (52–69) being cleared as soon as practicable, and by the end of 2014 at the latest.

Appendix A3—MapsNote well: the following maps provide a general indication of the areas that may be covered by each transmitter, but several important disclaimers should be noted:1. The presentation does not take account of predicted interference between

services.2. The presentation has used the CRCpredict diffraction-based coverage prediction

model. The predictions use best available information about nominal ERP levels and antenna patterns.

3. The presentation does not include an allowance for clutter losses.4. Figure A3.1 provides a simple ‘max server’ presentation which, in the case of

locations in areas of overlap between two coverages, will ascribe coverage to the transmitter that provides the highest ‘Band V equivalent’ field strength at the point in question. (Note: This max server presentation is based purely on field strength comparisons it does not consider whether the received field strengths are interference-free, nor does it consider viewer preferences for one site over another).

5. Figure A3.2 provides an indication of potential ‘suburban’ coverage contour of each of the Adelaide area repeater sites with the Mt Lofty services excluded.

These maps SHOULD NOT BE USED to provide advice about the coverage of particular transmitters. For that purpose readers should refer to the MySwitch web site at: http://myswitch.digitalready.gov.au/
