Abstract :
Advanced infrared (AIR) is a new standard of the Infrared Data Association (IRDA) to create wireless ad-hoc networks using a time division multiple access protocol (TDMA). The use of TDMA requires a physical layer providing approximate infrared channel symmetry and extended access-signaling range to reach all potentially interfering stations. We describe the underlying physical layer for AIR and derive transceiver parity conditions for achieving channel symmetry. In addition, we investigate the effects of channel asymmetry on the effectiveness of the access protocol
