Patent ID: 6928301

Claim:
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 said memory, and a baseband processing unit, said RF modem comprising: an antenna; an RF head coupled to said antenna and configured during a receive mode to receive an electromagnetic RF signal through said antenna and to convert said RF signal into a modulated baseband signal for baseband processing in said host computing device, said RF head further configured during a transmit mode to receive a modulated baseband signal generated by said host computing device and to convert said modulated baseband signal into an electromagnetic RF signal to feed to said antenna; and an interface coupled to said RF head and configured to physically couple said RF modem to said host computing device, said interface further configured during said receive mode to feed said modulated baseband signal generated by said RF head to said host computing device, such that said baseband processing unit in said host computing device is enabled to convert said modulated baseband signal into a plurality of bits of data including protocol data and true data, and said CPU in said host computing device operating under the control of said protocol stack software program is enabled to separate said protocol data from said true data, said interface further configured during said transmit mode to feed said modulated baseband signal generated by said host computing device to said RF head.
