Abstract

A adapter for wireless networking provides for reconfigerable media access control and data packet formats. The flexible adapter comprises a modem interface for controlling an RF modem for transmitting data signals to and receiving data signals from another RF modem; a media access control circuit; and a computer system interface circuit. The computer system interface circuit provides an interface between a host computer system, the modem interface circuit and the media access control circuit.
