An example of such a card is the AirCard 300 from Sierra Wireless, Inc. , with a transfer rate of 19.2Kbps. This allows anytime, anywhere data connection using the Mobile Phone data networks and frees an employee from the hardwire connection. Although a 19.2 Kbps transfer rate is not going to set your laptop on fire, it is fast enough to run a really Thin application like Flagship Accounting software. Other providers of CDPD modems are Inet, Motorola, Novatel Wirless and Uniden. Most of these cards are just under 3 inches long and have removable antenna, that plug into the outward facing surface of the card.
Some cards come bundled with utilities to ease installation and monitor connectivity.
These utilities enable you to do things like watch your signal strength and service connection while moving. Vendors like Flagship have Thin Client enabled their software so that users do not suffer software performance problems even when connecting to the Internet with a 19.2Kbps modem. Thin Client technology means that using a software application running over the Internet is as fast as using the software right there on your own network.
