Well I figured the new system would be P25 The current system has talk groups that are in analog as well as digital. The Bell FleetNet system is analog as well as digital and can be encrypted. EMS TGs being analog voice and OPP digital voice. What I was hoping is that the new system will be this way and keep analog interop talk groups available. I have an analog mobile and a P25 digital portable so I should be all good using my portable when I am in the Toronto region after this upcoming switch over. I must say though, I don't see EMS going digital because they would have to set up a new hospital patch system, and they can't really interrupt hospital patching just to install a new system and many fire services refuse to use digital voice systems because of distortion by the IMBE vocoder. Certain equipment and apparatus really mess up or distort transmissions when this type of sytem is used because the audio is a digital interpretation and transmission. I would hope if ALL public safety (including fire and EMS) migrates to this new system it will be dual mode and only the TPS talk groups digital. Otherwise keep EMS and fire on the analog Moto system. I'm curious to see the new systems structure when it is finally posted though to see who all will be affected.

I dont get much time to listen to Toronto EMS but they dont really do patches, I guess the dispatcher will call the hospital on CTS 1 & 2 calls. There used to be the odd Hospital patch (I forget the t/g 25936?) when they had to pronounce a patient or to give morphine and stuff like that.

Hopefully thet stay P25 digital and not encrypted. To this point most of us in the GTA can listen to pretty much everything but if they are going to switch there aint anything we can do about it,

They still patch into SOCPC Base Hospital if they need a physician consult for such things as STEMI patients, pronounciations, etc... This happens on MEDCON 1.

They don't patch to individual hospitals anymore. They tried this for a short while, but found that more often than not, the EOR was too busy to answer the radio and/or the ambulance was arriving before any useful information could be communicated.

They'll still pass along updates for serious patients however...but this is done on the regular quadrant channel via the dispatcher.

I’m sure this is Irrelevant to the course this thread is taking BUT where I live the OPP are digital. However! The digital coverage is so spotty that they require an Analog beet repeater just to maintain comms with the Com center. I know for a fact that the "new radio system" that they implemented in every new cruiser does not have the encryption feature built in. The only ones that do are the ERT and Drug units. They use voice inversion and they complain on a daily basis that’s it doesn’t work in the remote areas (mountain or rural areas). The portables that they carry are only good within 200 FT of the cruisers repeater in digital mode. There just isn’t enough tower coverage based on where the dispatch (Orillia) tower is located. As it stand there at times is an 8 to 10 second delay between the beat repeater and the digital coverage. Most just wish they would have stayed with analog.

You don't say where you are but I'm going to assume Orillia?

The digital coverage is so spotty that they require an Analog beet repeater just to maintain comms with the Com center.

The Fleetnet system was never designed to support portables. In Orillia and other towns where the OPP do foot patrols, they've installed BEAT repeaters (they call it the URBAN repeater in Orillia) to support the foot patrols. Since the regular officers only carry analog portables, there's no way they could use digital anyways.

The only ones that do are the ERT and Drug units.

ERT units do not have encryption as they are regular patrol units that have some specialized training. You're confusing them with the TRU team units who are dedicated to TRU work. You've also left out a whole pile of other units which have encryption: Crime, K9, Intelligence, TSB, VIP, etc, etc.

They use voice inversion and they complain on a daily basis that’s it doesn’t work in the remote areas (mountain or rural areas).

I wasn't aware that we've got any mountain ranges in Ontario and they definitely don't use speech inversion. There's no encryption on the analog channels at all and the digital talkgroups and conventional channels use DES-OFB encryption.

The portables that they carry are only good within 200 FT of the cruisers repeater in digital mode.

Yes, the system is designed that way so units in close proximity don't interfere with each other. The portables and repeaters are also analog only, no digital.

There just isn’t enough tower coverage based on where the dispatch (Orillia) tower is located. As it stand there at times is an 8 to 10 second delay between the beat repeater and the digital coverage. Most just wish they would have stayed with analog.

I listen to the URBAN repeater in Orillia on a regular basis and the most delay I've ever heard is 1 second and it seems to cover the Orillia downtown area fairly well. Where they do run into problems is when a mobile unit tries to use his portable in his vehicle while outside of the downtown area.

And further to what Mike said...the system was NEVER designed with portable level coverage in mind. It was designed for mobile level coverage, which it provides. Infact, there's nearly not a single place in Ontario you can go that doesn't have at least SOME mobile coverage. Sure, some areas aren't all that great, but that is going to happen no matter where you go. Coverage on Fleetnet is FAR better than the old NOR system. And while we're on that topic, NOR wasn't designed for portable coverage either (infact, they never made a portable that would even work on the NOR system).

You're mistaking "spotty coverage" with how the system was designed. Sure, they could have designed portable level coverage province wide but there'd be (at least) 3 times as many tower sites as there are now.

Bottom line is that Fleetnet provides better coverage and more flexibility than any other system the OPP/MOH/MTO/etc... has ever used.
