Hmm... I was wondering how long till that became public knowledge?

I especially like Table C.1 which lists all current GRN users and those expected to migrate from PMR by 2015.

I have never heard Surf Lifesaving on GRN, however it is listed in the document

Its a good document and shows some real and factual reasons behind the history of the GRN, rather than the slanted crap you usually hear.

eg - NSW Police's justification for not going GRN appears totally valid from that document and that the agencies are working closely together to figure out a solution. Makes me feel like our tax dollars aren't being wasted as badly as I thought

I was thinking the same thing.

When you look at the cost structures I find it hard to believe the police (therefore NSW Govt and the NSW people) would be in a better financial position if they were to switch to the GRN. Seems like, at this stage anyway, the cost (and benefits) of remaining on their own PMR system far outweigh any benefit of the GRN.

This paragraph especially stood out: "...the GRN was originally designed for in-vehicle radios but the NSW Police Force
requires signal penetration into buildings. This means that sites need to be relatively close to each other. However the GRN’s 30 sites in the Sydney metropolitan area compares unfavourably to the 110 in the NSWPF network"

From the above, how can the GRN ever possibly compare?

I like the Vic MMR solution - reuse and add some of the 468Mhz allocations to the GRN to cover areas that are needed.

I would say that's what they'll do? Does anyone know if the NSWPF's radio fleet are UHF1 (403-470MHz) or UHF2 (450-520MHz) radios? If they are the latter then it would be a foregone conclusion that the GRN will have to recycle their 468MHz gear otherwise the PF would have to replace their entire radio fleet!

EDIT: I just realised that the PF radios would still need access to the low-band GRN site control channels anyway so their radios would have to be range 1?

I'd say they are referring to the Westpac Rescue choppers which are on the GRN already (which is why Careflight and Childflight are also on the list) however, SLS do have their own PMR network so who knows, maybe their beach patrols etc. will also be moved across when the time comes?

I can already see capacity problems with the way they've divided up RID blocks, there will either be a bit of re-farming needed or there will be quite a few agencies sharing RID allocations?

I believe (just my feeling) that most of NSWPF are range 1 with the exception of special ops units that need access to things above 470MHz..

With the NSWPF going onto the GRN they would have to replace a lot of the handheld radios, which are XTS3000's. These are not able to do P25 9600. All these radios would have to be replaced.

already budgeted. they are already getting replaced with xts2500,5000, xtl etc
