  1. US GSM coverage by glassesmonkey · · Score: 2, Informative · on How (and how well) do Wireless "Worldphones" Work?
    Ok I meant half of the US cities instead of most. I don't think GPRS phones work in Europe.
    CDMA networks (like Sprint and Verizon)
    GSM/GPRS networks (like T-Mobile and Cingular)
    Nort America Coverage Map
    Typical US markets are a mix of the following: (800=800 MHz; 1900=1900 MHz)

    800 AMPS

    800 TDMA

    800 CDMA (verizon)

    800 iDen (nextel)

    1900 CDMA (sprint pcs)

    1900 GSM (at&t, cingular, t-mobile)

    1900 TDMA (at&t)

  2. Re:GSM = cheap? by ces · · Score: 1 · on Delays and Problems for India's New CDMA Network

    I found a nifty map of CDMA vs. GSM at http://www.gsmcoverage.co.uk/maps/europe/gsm_cdma_ map.jpg.

    It looks like South America has gone CDMA as well.

    Of the areas with both CDMA and GSM I would suspect GSM has the most market share in Europe and Asia while CDMA has the most in North and South America.

    > GSM? WHICH GSM? Africa, US or European frequency?

    Dual Band 800/1900 as in Syria, Turkey, Saudi Arabia, Iran, Kuwait.. Meaning all the neighbours. Or as you call it, "European".

  7. Re:Bluetooth - necessary in 802.11 world? by Simon+Brooke · · Score: 2 · on Bluetooth Bombs
    The incompatibilities are because of the usual crap between countries and companies. Part of the same reason that we have competing incompatible regional cellular networks. Hopefully it'll get fixed to the point where it's "good enough".

    America has competing incompatible regional cellular networks. Japan has iMode (arguably the best). The rest of the world has GSM. I can take my phone to anywhere from Albania to Zimbabwe, and it will work.
