Abstract
An inexpensive, PCMCIA-based radio transceiver is provided that interfaces to a separate baseband modem, which may itself be PCMCIA-based or may be an internal modem of a notebook computer. Together, the PCMCIA-based radio transceiver and the baseband modem realize a wireless modem. In order to miminize cost and increase versatility of the resulting wireless modem, the radio transceiver is a relatively unintelligent, protocol-agnostic, slave device that is controlled by commands issued by the baseband modem. The baseband modem may be a hardware modem or a software modem. In either case, the character of the baseband modem may be changed by downloading new software. The radio transceiver may also be exchanged for another within a family of radio transceivers, each of which customized for a particular radio standard. The result is an extremely flexible, extremely low-cost wireless modem solution.
