The new emergency services communication network is already in the<br>
planning stages, it has been mentioned here previously.<br>
Ambos and Fire will be on the network which is all digital-based, but word<br>
is they will not be encrypted. There really is no need for them to be.<br>
There's actually no need for Police to be encrypted either, but that's a<br>
whole other argument.<br>

Encryption itself isn't expensive at all.? You use the same radios, in <br>
fact a lot of St John radios are already TP9400 and TM9400s, new builds <br>
are all getting the new radios.? They will need to purchase a trunking <br>
key per radio to use the new network, but that can be added later on <br>
when the new codeplug is uploaded to the radio.<br>
<br>
I haven't done encryption on any Tx9400s, but for TM/TP93 and MotoTRBO <br>
radios, to encrypt is literally about 5 more seconds of work for the <br>
programmer.? Now if they use fancy high end encryption, then you use a <br>
keyloader which is a hardware device.<br>
<br>
Fire will potentially have a harder time, due to the way the vehicle <br>
wiring is installed... The story I was told is that it's cheaper for <br>
them to repair the T2000 based equipment than to swap each vehicle over <br>
to TM8200s (changing from an 8200 to a 9400 is straightforward as you <br>
only need to replace the head and the body - the remote cable in between <br>
is the same)<br>
<br>
Reports I've read is that NGCC will be RF, Cellular and satellite based, <br>
however will need to be compatible with the existing P25 network in use <br>
in Auckland, Wellington and Christchurch.<br>

This new system has been spoken about for some time, its will be worked<br>
from the spark cellular network starting with police with the long term<br>
plan is to include the other services. There is a document out there that<br>
explains the roll out. Cant remember the name of it.<br>

So is the data and satellite function going to work off cell towers and<br>
radio comms off dedicated repeaters or are they all off the cell towers?<br>
With the assumption of P25 for all I'm guessing radio will not be off cell<br>
towers?<br>
England have terrestrial trunked radio which is more cellular than anything.<br>
