Statewide government trunked radio systems in Australia

Add links
From Wikipedia, the free encyclopedia

The Government Radio Network (GRN) is a network of various systems in place across Australia that enable statewide trunked radio communication. The network operates through inter-linked sites for government and public services such as police, ambulance, fire, or roads authorities which require such a system to function properly. The main aim of the GRN is to consolidate all resources into one network, ensuring greater coverage and reliability than if each department had its own independent communication system. The existence of the GRN also reduces the amount of government money and resources needed to maintain communication between units of emergency and public service branches. Last, it allows effective intercommunication among these services in times of national or state emergency for coordination of wide-scale actions.

Australian Capital Territory Radio Network (TRN)[edit]

The Australian Capital Territory Radio Network (commonly referred to as the TRN) is a trunked radio system operating in the Australian Capital Territory, Australia. The network was introduced in 2004, and provides 100% coverage of the ACT.[1] The network is used by ACT Emergency Services Agencies (ESA) and other ACT Government agencies including ACTION buses, TAMS (Territory and Municipal Services), ACT Health and Roads ACT.[1]

The network is part of the NSW GRN, and is controlled and maintained as part of that network. It is managed separately by the ACT Government.

New South Wales Public Safety Network (NSW PSN)[edit]

Overview[edit]

The New South Wales Public Safety Network (previously referred to as the New South Wales Government Radio Network or NSW GRN) is a trunked radio system operating in the state of New South Wales, Australia.[2] Established in 1993, the network was the first government trunked radio network in Australia and is one of the largest in the world.[3] The NSW GRN covers more than 80% of New South Wales and approximately 96% of the urban population.[4] The network is owned by the NSW Government through the NSW Telco Authority and the network's operations are managed under contract.[5]

Network Users[edit]

The network is used by all NSW and ACT emergency services in varying capacities, along with other agencies, departments, services, and non-government organisations, including:[6]

The network is also used by other government departments and discrete law enforcement agencies.

Network Information[edit]

South Australia Government Radio Network (SAGRN)[edit]

Overview[edit]

The SA Government Radio Network (referred to as the SAGRN) is a trunked radio system operating in the state of South Australia, Australia

The SAGRN is one of the largest and most comprehensive public safety networks in the world, covering over 265,000 square kilometres and providing coverage to more than 99.5% of South Australia’s population including 20km offshore coverage along the State's coast.

The SAGRN includes a statewide Paging network that is used for the dispatch of Ambulance, MFS, CFS and SES resources. The Paging network is integrated with the Computer Aided Dispatch system used at the Triple Zero Emergency Operations Centres.

Telstra originally constructed the SAGRN in the early 2000's,[13] the network replaced 28 separate systems. Telstra supported the network until 2010.

In 2010, Motorola entered into a contract with the South Australian Government to support the SAGRN.[14]

In 2015, Motorola entered into contracts to upgrade the SAGRN and operate it. [15]

Network Users[edit]

The SAGRN is used by over 25 government and non-government agencies including

The network is also used by other government departments and law enforcement agencies.

Network Information[edit]

The SAGRN Voice Network is a digital Project 25 (known as P25 or APCO-25) Phase 1 trunked radio system operating in the Harmonised Government Spectrum [16] in the UHF band.

The SAGRN Voice network is built on Motorola Astro-25 network equipment.

P25 Voice terminal equipment is supplied via a panel of suppliers of compatible P25 radios.

Tasmanian Government Radio Network (TasGRN)[edit]

The Tasmanian Government Radio Network (TasGRN) is a project to establish a single digital communications network for a number of Tasmanian government organisations.[17]

Victorian Government Radio Networks[edit]

Melbourne Metropolitan Radio (MMR)[edit]

The Metropolitan Mobile Radio (MMR) service is a Project 25 (APCO-25) Phase 1 radio voice communications system. It provides communications over the Greater Metropolitan area supporting Victoria Police, Ambulance Victoria and the Metropolitan Fire and Emergency Services Board.[18]

The current users are limited to Emergency Services which are:

All digital scanning receivers are able to decode the unencrypted conventional P25 channels. End user equipment is supplied by Motorola, primarily XTS5000 portables and XTL5000 mobiles.

Regional Mobile Radio (RMR)[edit]

The Regional Mobile Radio (RMR) network is a digital VHF P25 (Phase I & II) trunking network managed by Telstra Corporation.[19] The RMR was initially designed as the Regional Radio Dispatch Service (RRDS) Project for the Country Fire Authority (CFA).

Towards the end of June 2013 the first two trunking sites were switched on for the RMR with all CFA bridges transitioned by August 2014 to the RMR that will become the primary communications system for contacting fire dispatchers used by the CFA. Augmenting its older Analogue VHF Network the RMR network is being used for incident dispatching and emergency communications with statewide fire dispatchers with the older analogue VHF network being slowly decommissioned or repurposed and analogue simplex radio communications being used for local and fire ground radio communications.

In 2016, it was announced that regional Victoria Police would transition to the network with encryption. The transition was successfully completed to encrypted communications on the morning of 20 November 2018. The Victoria State Emergency Services, Life Saving Victoria and Corrections Victoria will also transition.[20]

The current users of the network are:

The current end user equipment used by the CFA is supplied by Tait Communications and consists of custom CFA branded TM9100s and TP9100s.

The current end user equipment used by the State Emergency Service is supplied by Motorola Solutions and Telstra and consists of Motorola APX 7500 VHF/UHF Mobile and Motorola APX 6000XE Portable radios.

The current end user equipment used by Rural Police is supplied by Motorola Solutions and Telstra and consists of Motorola APX 8500 Mobile and APX 8000H Portable radios.

Victorian StateNet Mobile Radio Network (SMR)[edit]
