Abstract: A transceiver card for a personal computer includes a single circuit board that plugs into the personal computer and that is coupled to exchange data via an industry-standard bus in the personal computer. Radio frequency modulation circuitry on the circuit board receives the data and transmits radio frequency signals responsive thereto. Receiver circuitry receives radio frequency signals and converts the received signals to data for transfer via the bus. In an alternative configuration, the transceiver includes two circuit boards coupled to a USB bus within an external box. Data is exchanged with the computer through a USB port in the computer.
