Abstract

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.

Claims

1. A method of operation of a wireless access system having a subscriber subsystem gateway and a wireless router in communication with the subscriber subsystem gateway via a two-way radio channel according to a communication protocol, the method comprising the steps of:

measuring an instantaneous error characteristic of the channel; and

selectively fragmenting packets to be sent from the wireless router to the subscriber subsystem gateway to a degree of fragmentation dependent on the instantaneous error characteristic of the channel.
