t Bluetooth will be a major connection method. An ideal solution involves inexpensive, low-power, easy-to-use components. PANs can and should have a relatively short operating range and don't need high bandwidth. Bluetooth's design objectives fit the profile of an ideal PAN, but today the advantages of using Bluetooth devices are complicated by configuration, interface, and other problems, and they still cost too much. If you go beyond integrated devices and phone combinations, there is alot of two-device solutions that connect PDAs and digital cell phones. You can use serial cables, CF cards with cables for specific phone models, infrared data modems in cell phones, and slide-in accessories such as the Visor Phone(1 Fact Sheet, www.solveit.com). None of these solutions are easy, and none are cheap, like for us College ISOM students its practically impossible. One of the greatest roadblocks to the wireless dream, unlike Europe is the stupid providers of networks and carriers in the U.S, they absolutely stink, in addition to always charging more than you use. Maintaining continuous and reliable coverage is also a big problem; remember all those dropped phone calls. Carriers continue to build out their networks, and are ignoring the real problem of increased bandwidth, while balancing the continued delays of third-generation cell phone networks(2, White Paper, www.broadcloud.com). "When 3G first rolls out in early to mid-2002 (in two major versions, WCDMA and the ironically named CDMA 2000), the outlook for combined devices should improve."(PC MAGAZINE) Until then you'll have to be satisfied with existing two-device solutions.
             There are many different communication providers that provide Satellite like Skycell; with various dispatch, data, voice and facsimile services. Hybrid Networks (satellite/terrestrial) are plenty abound for example ARDIS which supports remote office staff, fleet dispatch, maritime, and public sa...
