      Starting in May of 2001 I used CDPD with Omnisky on both Palm and PocketPC. The PocketPC setup was a Sierra Wireless AirCard 300 CDPD PC Card for Handhelds with an iPAQ 3670 (must pause to inhale... OK :-) in the Washington, DC metro area. It was the Omnisky network (which runs on Verizon on the Boston/NYC/Philly/Balt/Wash corridor) With a strong signal, it works pretty well... response times are spiffy, while content loads...er... eventually. Much better suited for IM than for browsing. All you need is one slight interruption of signal for the thing to get confused. At those times, I would usually need to stop whatever I was doing (browsing or IM), disconnect and reconnect the modem connection and start over. Sometimes, if the signal drop was very brief, it would be OK. When the signal was strong, though, I could IM and browse at the same time without it being very obvious that I was using a slow connection (to the other IM user, I mean). Another thing I disliked was the removable antenna on the AirCard... that thing was just waiting to be bent or lost. Also while the modem is on the batteries get sucked dry within couple of hours of constant use... and that's with the external battery contained in the iPAQ PC Card sled!


      The Palm setup was a Vx with the Novatel Wireless sled. This, of course, was a bit less bulky than the iPAQ with the PC Card sled, and I liked the retractable antenna. However, unlike the iPAQ where you could charge both batteries simultaneously, you have to charge the Palm and the sled separately. Also it seemed like the Palm combo was just as vulnerable to network holes and spottiness.


      I stopped using both accounts because of the inconveniences caused apparantly by the hardware's inability to hold on to a signal. What was gained in convenience by the small form factor was more than washed out by those problems. I would rather wait for a GSM+GPRS-based solution (only because I perceive GPRS to be both faster and less spotty, not because I have empirical data comparing the two).

      Has anyone here had any CDPD experience?

      Sure, I used the Omnisky service for a couple of years. My take in brief: CDPD sucks.

      They claim 19.2kbps; I rarely saw a quarter of that. But worse than that is the fact that you lose service if you're moving around very much ... e.g. in a car or on a train. Coverage is poor, too, even in major urban areas (e.g. Boston and New York City).

      I had hoped to use the service to expand the capabilities of the palmtop device by allowing remote access to deep datastores (the web, of course, but also mail archives and personal files). The reality was that it was too slow and unreliable to use for anything but short data bursts ala AvantGo. I could only use it for e-mail in emergency situations, and it was next to worthless for the web both because of performance and display limitations.

      The 2.5G network Verizon is rolling out may have a better shot at it. With much higher data rates and presumably better handling of cell migration it might just be good enough. Until then I'm using 802.11 despite its short range. CDPD is a bust.

    CDPD - Cellular Digital Packet Data.

    The CDPD system involves sending short, relatively low speed data bursts over a voice channel of standard North American Analog Phone Service (AMPS). This allows a standard AMPS system to carry CDPD with little retrofitting of the cell towers, whereas GPRS requires a whole new system. Given that your average cell site runs about US$1M, that adds up very quickly.

    CDPD is a CS/A TDMA system (Collision Sense/Collision Avoidance Time Domain Multiple Access) system - Multiple users transmit on the same frequency at different times, much like Ethernet.

    CDPD is in common use for vending machines, electric meters, and other systems that need to report relatively little information.
