    Their "high-speed wireless link", is that like WiFi, as in they can access web sites -albeit intranet sites - but a special cop version of WiFi ?
    Generally, the PD and Public Service data stuff is handles in one of a couple of ways. The "Modem" is interfaced either with a dedicated DATA radio, which operates on a seperate channel (Although I am sure there are systems where the data is carried on the voice channel somewhere. It does depend on the load of the data and voice on the channel), OR, they interface to a Cellular Data service, such as CDMA. I Have yet to see a Public Service rely on 802.11. 802.1 is severly limited in range as compared to the coverage provided by a cellular service with lots of real estate coverage, or with a DATA radio that operates in the spectrum that has much greater real estate coverage. Plus, 802.11 is pretty new, and most of the DATA systems have been around since before 802.11, and at a time that they were setting up thier radio systems. It is easier and cheaper to cover a city with ten 800mhz radio sites, then 100 802.11 sites.

    The Data system is generally used for several things for PD. Dispatch, they get the job information over the screen. They can indicate thier status, such as on the way to the scene, on scene, available, at meal, blah blahblah. They can also send messages between each other. THey can look up license and registration informaion. Often times, they can fill out and file reports and the like. THEY CAN NOT ACCESS THE INTERNET

    I don't, however, recognize the radios they are using there. They look a little like GE (Certainly not motorola). Can you tell me what they are using?

    A very brief visual inspecition of the modem pic would indicate they use the Nextel network. Nextel utilizes the iDEN protocol, which allows enhanced data as well as voice (including ptt, but they wouldnt need that)...

    Thats what iden is anyways.. I noticed the modem has several iDEN leds... (spelled with a capital DEN and lowercase I....like motorola/nextel's iDEN)

    I wonder how good their PSU is... and how expensive... I suppose it would be more reliable than an opus or something...and I wonder how strong it is... probably under 200w, as the most they provide is something round a PM1.6ghz

    Actually, IDEN is a protocal. Not necessarily Nextel. Motorola has several trunking formats, and one of them is IDEN. I doubt it is nextel. They are probably using a trunked 800 simulcast system, with several channels for voice, and Data. Hence the IDEN.

    Well, the fastest DATA network I have heard of in Public Service is like 9600k. They don't really transfer graphics. IT is generally just text.

    I think some graphics are important. I hear in beverly hills they pull up the driver's picture.

    it probably isnt larger than 10 or 15kb... the quality isnt that good.... have you seen how long they take when they go check their computers in their cars when you get pulled over? it seems like 20 minutes each time... maybe they are just waiting!
