1. A wireless radio frequency (RF) modem constructed to cooperatively operate with a host computing device having a memory, a central processing unit (“
- CPU”
) for executing a protocol stack software program stored in the memory, and a baseband processing unit, the RF modem comprising;
an interface configured to physically couple the RF modem to the host computing device, the interface further configured during a receive mode to feed a modulated baseband signal generated by the RF modem to the host computing device, such that the baseband processing unit in the host computing device is enabled to covert the modulated baseband signal into a plurality of bits of data including protocol data and true data, and the CPU in the host computing device operating under the control of the protocol stack software program is enabled to separate the protocol data from the true data, the interface further configured during a transmit mode to feed a modulated baseband signal generated by the host computing device to the RF modem.

Abstract
The present invention provides for a wireless radio frequency (“RF”) modem that plugs into a host computer and shares a central processing unit and memory with the host computer, wherein principal modem functions are distributed between the modem and the host computer. In one embodiment, the modem performs RF conversion, and the host computer performs baseband processing and protocol stack control. In another embodiment, the modem performs RF conversion and baseband processing, and the host computer performs protocol stack control.
