APPARATUSES AND METHODS FOR DISTRIBUTED RATE ALLOWANCE AND COLLISION DETECTION IN WIRELESS NETWORKS

摘要

A hybrid cellular and non-cellular multi-hop communication device, including a hand-held wireless device having one or more antennas, a cellular wireless interface connected to at least some of the one or more antennas, and a non-cellular wireless interface connected to at least some of the one or more antennas. The non-cellular wireless interface may include a rate allocator configured to select a physical-layer rate of transmission of data from the non- cellular wireless interface based on a queue length of data to be transmitted from the hand¬ held cellular device and a transmitter configured to wirelessly transmit data from the queue and adjust physical-layer transmission parameters based on a physical-layer rate selected by the rate allocator.
