Demands for Radio Network
• The network has to be operational all the time 24/7/365
• The coverage should be adequate all the working area (including indoors)
21st May 2013

Länsi-Uudenmaan pelastuslaitos | Västra Nylands räddningsverk | Länsi-Uusimaa Department for Rescue Services
Indoor Coverage
• First the coverage should be assured without active extra installations
• Secondarily there may be need for active TMO repeaters or base stations (TBS)– big building complexes (for example malls)– underground spaces
21st May 2013

Länsi-Uudenmaan pelastuslaitos | Västra Nylands räddningsverk | Länsi-Uusimaa Department for Rescue Services
Why Active Repeaters?• Traditionally fire fighters communicated
from terminal to terminal without connection to base station– TETRA DMO
• But if we want to have full advantage from TETRA network, the terminal needs the base station connection– TBS– Fixed repeaters– DMO Gateway terminals

Rule for Securing the VIRVE-services in Buildings
• The State Security Networks rule for planners and contractors
• Technology and process, when there is need for built-in active solutions (repeaters)

Three Ways for Indoor Coverage solution:
1. Authority specification for building license (new building)
2. Authority specification afterwards (existing building), Rescue Act
3. Owner specification (user demand, security level of building)

Rescue Act 109 §: Special requirements concerning the operability of the public
authority network“If the operability of the public authority network referred to in section of the Communications Market Act (393/2003) in a building or structure with an unusually high risk to the safety of persons is obstructed as a result of a structural reason arising from the building or the structure, and if the operability of the public authority network is not sufficient for carrying out the rescue operations in an appropriate manner, regional rescue authorities may order the owner of the building or structure to purchase the necessary equipment for ensuring the operability of the public authority network and to keep the equipment in working order.”

The Process
Länsi-Uudenmaan pelastuslaitos | Västra Nylands räddningsverk | Länsi-Uusimaa Department for Rescue Services
The Evaluation for Needs
• Planner fills special form with Rescue Authority (similar as used with Fire Alarm Systems)
• The form will be attached to building license documents
• The evaluation is needed for– Major gathering- and business premises– Underground spaces (not for ordinary basements)– When there is need for Automatic Fire Extinguishing or
Alarm system
21st May 2013

Länsi-Uudenmaan pelastuslaitos | Västra Nylands räddningsverk | Länsi-Uusimaa Department for Rescue Services
The Evaluation for Needs
• The form is attached to Rescue Services Rule– Like the documentation of Fire Alarm System
• Probably there is no need for special repeater solution• If the repeater solution is needed
– National Emergency Supply Agency covers the cost of the repeater– Owner covers the cost of wiring and other installations (power supply)– The State Security Networks owns and maintains the repeater
• The State Security Networks ltd trains and maintain the valid list of planners and contractors trained by them– actually there is no validation method for the planners and contractors
21st May 2013

Procurement of the Repeater
• The State Security Networks ltd. defines the specifications for the repeater
• The State Security Networks ltd. runs the public tender process for the repeaters (app. every 3rd year) and makes general agreement with distributors
• Other active repeater installations are not allowed in the VIRVE-network
21st May 2013
19
Länsi-Uudenmaan pelastuslaitos | Västra Nylands räddningsverk | Länsi-Uusimaa Department for Rescue Services
Indoor Coverage
• Entire building (field strength ≥-86 dBm at 90 % probability)– Especially covered
• Escape and rescue routes• Technical rooms for safety and security (i.e. control rooms,
sprinkler centrals)
• Specially defined areas (marked to attached blueprints)– User needs i.e. hospitals and security premises– Underground spaces

Approval
• The contractor send the installation folder to the State Security Networks
• The subscriber makes the visual inspection that all of the installation are correct
• The contractor or the planner shows for the owner of the building (subscriber) that the need for indoor coverage is correctly secured
• After the installations and the needs of coverage seems to be correct, the subscriber accepts installation and informs the State Security Networks ltd that the indoor solution is ready for final inspection

Länsi-Uudenmaan pelastuslaitos | Västra Nylands räddningsverk | Länsi-Uusimaa Department for Rescue Services
Final Inspection• Is done by the State Security Networks ltd
– The inspection and frequency license are subscribed from the State Security Networks
– The State Security Networks inspects the installations, rf-details, network service availability and that the indoor solution does not make any interference to outside of building or to other installations
• The contractor shows all the installation documents• In the form is given mark of approval
– The contractor confirms that all the installation has done as planned and documented
– The State Security Networks ltd has approved the repeater to be connected to VIRVE-network

Initialization
• After the final inspection the State Security Networks gives the permit to use the repeater
• During the initialization process the repeater is connected to the monitoring system of the State Security Networks and the repeater is officially in use– For the stability of the network and frequency utilization it is necessary, that
the operator controls the active repeaters!
• The State Security Networks informs the subscriber (owner of building) that the repeater is in use

Finally• The TETRA-technology is not the problem• What about the conditions that the system should
tolerate – Buildings and tunnels under construction– Fire and flooding (how to protect the installations?)– Lack of electricity (how long the indoor coverage is available without external
power?)– Building Collapse– Criminal acts– Exceptional circumstances– How does the rescue units know that there is built-in solution?
21st May 2013

Länsi-Uudenmaan pelastuslaitos | Västra Nylands räddningsverk | Länsi-Uusimaa Department for Rescue Services
How to secure the indoor coverage
• Duplicate the system– Douple repeaters feeding same leaky cable– Double repeaters, cables and antennas RF planning
• Back-up system– DMO gateways and repeaters– Fixed or portable telephone lines (field phone)
