I believe there might have been a thread earlier on it. Looks like the jails are going NXDN.

If so that's a pretty good contract for Kenwood. I wonder why they went with NXDN over MotoTRBO since TRBO doubles your available channels. Plus, from what I've heard 3rd hand... NXDN doesn't sound all that great.

Unknown why they went NXDN - probably someone bought dinner for the right person. The system is said to be encrypted - unknown if it is. If so, waste of money as no one wants to hear "Open door 637" all day long...... I'll bet money they aren't capable of inter agency operation with Toronto Fire/Police/EMS which in case of emergency/riot will be a great problem......

Encryption is a standard feature on the NXDN radios, so no additional costs.

NXDN sounds just fine if the person setting up the radio knows what they are doing, it uses the same vocoder as Trbo and P25.

Trbo does provide two time slots per repeater, but then you have both "channels" in one box. One failure means you've lost two channels.

Of course there is the brand loyalty to Motorola, thats one thing that's hard to overcome.

As for interoperability, the NXDN radios do analog just fine.

Bad advice. Correctional facilities whether provincial or federal are not in TAFL.

They're considered protected.

I would be going P25, what happens 7-10 years from now if Motorola or Kenwood come out with something more updated and discontinue support for TRBO/NXDN? P25 let's you choose multiple vendors for hardware down the road. These other formats might be great but is there a guarantee of support for at least 20 years? Then again I am sure they will one day stop making P25 Phase 1 hardware.

This will always be a risk. There are a lot of NexEdge/NXDN users in this area. Most of the shops that run LTR networks are migrating to NXDN, some of them are large (30+ site) networks. With that sort of demand for NXDN, not to mention Trbo, the support will be around for a while. Most non-public safety users can't afford P25 gear, and analog only equipment is not as popular as it was 5 years ago. I don't think NXDN/Trbo is going to disappear anytime soon.

P25 is great, but the cost is too high for most smaller agencies. Interoperability is good, but it doesn't necessarily need to be digital. Trbo, NXDN and P25 radios all do Analog, so there is a common ground. Of course coverage, band, proper programming, etc all come into play, too.
