TASMANIAN GRN

[cartman]

As many of you are aware the Tasmania Government put out a request for tender on 24 November 2018 for a single P25-compliant Tasmanian Government Radio Network (TasGRN) to provide enhanced communication and facilitate interoperability between Tasmania Police, Tasmania Fire Service, Ambulance Tasmania, State Emergency Service, Parks and Wildlife Service, Sustainable Timber Tasmania, TasNetworks and Hydro Tasmania.

Subsequent to that, no information on the outcome of that tender has been forthcoming.

However as the folk on the Tasmania scanning forum have noted, it is starting to look like Telstra is going to get the nod and perhaps the TasGRN set up to link in with the Victorian MMR/RMR systems (similar to the way the ACT run their system off the NSWGRN)

Interesting developments

VHF and UHF - hopefully it won’t be a mash-up like in VIC and they will settle on one band.

Looks more like testing signal performance perhaps.
VHF would probably perform better in the mountainous terrain

[Radio_Australia]

VHF would definitely be the good choice due to terrain , but UHF is better for building penetration

[Scotty]

UHF would have to be the better all round choice for many reasons, including better interoperability with (essentially) all other states GRN networks.

And with the current EDACS network down there in the 800MHz band there would likely be little real world change if they were to go UHF.

It’s nothing a Interoperability Gateway can’t fix

Telstra Fleetcoms (now on its way out) has VHF and UHF sites. Often they are collocated. They feed in to the same switch and radios can converse with each other from either band, via private call or talkgroup call. Nothing new here.

So with such a radio network, you could hypothetically make say suburban / city areas UHF and country / mountainous areas VHF, and have complete interoperability. If you had appropriate dual band radios, you would never be out of coverage despite the site's frequency band.

Alternatively:

UHF Mobile & VHF Portable, for normally city / suburban vehicles.
VHF Mobiles & UHF Portable, for normally country vehicles.

Split frequency may well be complimentary, but certainly a bit more engineering involved.

But as stated just UHF would be better than 800 MHz

Telstra to build Tasmania's Govt radio network

Tender Information
The Tasmanian Government Radio Network (TasGRN) has taken a significant step forward with the commencement of contract negotiations with Telstra Corporation in partnership with Motorola Solutions Australia.

After an extensive tender process during 2018 and 2019 Telstra Corporation were identified as the preferred tenderer. Telstra and Motorola jointly implemented the Queensland Government Wireless Network and are uniquely positioned to design a contemporary system suited to the Tasmanian context.

The Minister of Police, Fire and Emergency Management issued a media release on 9 August 2020.

"Telstra has been awarded a contract to build a government radio network for the Tasmanian Government to modernise the state’s emergency services and agency communications capabilities.
Called the Tasmanian Government Radio Network (TasGRN), the network would replace five existing, separate radio networks to create a unified and interoperable radio network.
The network would be used initially by eight Government organisations, including Tasmania Police, Tasmania Fire Service, Ambulance Tasmania, State Emergency Service, Sustainable Timber Tasmania, Department of Primary Industries, Parks, Water and Environment, TasNetworks and Hydro Tasmania.
Tasmanian Government minister for police, fire and emergency management Mark Shelton said TasGRN would allow the agencies better serve the Tasmanian community and keep Tasmanians safe.
“Recent events both here, and in other Australian jurisdictions, have shown us how important it is to have fast and secure communications to respond to bushfires, floods, natural disasters, and other emergencies,” Shelton said.
“The new TasGRN will give our emergency services and key government agencies an integrated radio network that is purpose-built for the needs of Tasmania. This delivers on past review recommendations, including the 2013 Tasmanian Bushfires Inquiry into the Dunalley bushfires.”
Shelton added the network is expected to create up to 50 jobs during the three-year construction phase, with additional positions to help run and oversee the network once it is up and running.
Telstra enterprise group executive Michael Ebeid said the TasGRN would be the telco’s largest single project carried out in Tasmania.
“This will be a brand new government public safety grade radio network that will be fit-for-purpose, meeting the demands of a modern Tasmania and the more than 10,000 employees and volunteers who’ll use it,” Ebeid said."

[Bigfella237]

It's a P25 system (same as all the other states) with a WACN ID of BEE00-5E3

There are a few people on the Unitrunker forum monitoring it's rollout, apparently there's at least one site running already at Mt Rumney but I haven't looked any further.

Does anyone happen to know what ACMA client ID all the freqs are licenced under?
