Abstract
In order to better manage VoIP transmissions between an AP and multiple voice client devices, methods are described that use synchronization techniques combined with packet concatenation to greatly reduce latency and jitter while enabling a much larger number of simultaneous conversations than would otherwise be possible. A TDMA-style methodology is superimposed over the standard CSMA/CA mechanism of 802.11 to provide the benefits of both mechanisms while remaining fully compatible with an industry standard protocol. The synchronization/concatenation mechanism may be optionally used in conjunction with a wireless mesh network to provide enhanced roaming as well as the ability for concatenated VoIP packets to be distributed over a wider area, and in much greater quantity, through the mesh.
