A wireless access system having a subscriber subsystem gateway ( 20 ) and a wireless router ( 30 ) in communication with the gateway via a two-way radio channel ( 25 ) according to a communication protocol. The communication protocol has a medium access control (MAC) layer ( 602, 603, 604, 605 ) capable of supporting several different network layer frame types ( 610 - 612 and 613 - 615 ) and includes a MAC layer header ( 800 ) having a frame type indicator ( 801 ), so that multiple frames of differing frame types are communicated contiguously over the radio channel separated by MAC layer headers.
