Wireless Communications FAQ
Wireless communications provides easy access to information wherever you are. It is designed to work where landlines don't go. This article focuses on Ardis, BellSouth Wireless Data (formerly RAM Mobile Data), CDPD (Cellular Digital Packet Data), Cellular (AMPS, GSM, CDMA, GPRS, 1xRTT), and Ricochet Microcellular Data Network. One of the most important issues with wireless communications is where is it available. I recommend that you review each provider before deciding which service to select.
Also for internet connectivity, you will need another service provider. Examples of providers include Go America, Omnisky, Ricochet, etc. They normally partner with specific service providers to offer a complete package of hardware and services. Some providers such as Go America offer both PDA and desktop support with the same peripheral to connect to the internet.
At this time Windows CE does not include in rom initialization settings for Cellular communications. You will need to contact your modem vendor for assistance in configuring the extra settings for the modem. I recommend that you have 2 dialup connections - one for landlines and another for cellular.
You can transfer contacts to your SMS phone via HandPhone. It also allows you to send and receive SMS messages as well!
Campus Wireless LANs
There are 2 standards for campus wireless LANs - OpenAir and 802.11. They both operate at 2.4 to 2.485 ghz. 802.11 operates at 1mb or 2mb(optional). Right now 802.11b product are interoperable and tested by WiFi. OpenAir products operate at 1.6 mb are tested interoperable and test by the WLIF. Both OpenAir and 802.11 products do not require an FCC license. Some of the vendors offer encryption of data as well. For OpenAir users none of the vendors offer encryption however frequency hopping would be very difficult to decode.
