摘要： A programmable transmitter generates a frame preamble to train a receiver with respect to a communication link format that corresponds to a transmission mode wherein the transmission mode may comprise transmitting the communication link over one or more antennas. Generally, the invention includes generating a preamble with an arrangement that depends upon whether a Greenfield (high data rate) or mixed mode transmission is to occur and that depends upon a number of spatial streams that are to be generated. One format for high data rate transmission includes a short training sequence, a long training sequence and a signal field. The mixed mode transmission further includes a legacy prefix.

摘要： A method for configuring a multiple input multiple output (MIMO) wireless communication begins by generating a plurality of preambles for a plurality of transmit antennas. Each of the plurality of preambles includes a carrier detection sequence at a legacy transmit rate, a first channel sounding at the legacy transmit rate, a signal field at the legacy transmit rate, and Z−1 channel soundings at a MIMO transmit rate, where L corresponds to a number of channel soundings. The method continues by simultaneously transmitting the plurality of preambles via the plurality of transmit antennas.

摘要： Protocol adaptation layer for wireless communications. Communication devices that include one or more radio modules operable in accordance with multiple communication protocols establish communications using one communication protocol and then switch to another communication protocol. This switching to another communication protocol may be performed based on a variety of factors including effectuating communications of higher throughput, supporting uni-directional communications vs. bi-directional communications, or any other desired factor. In some embodiments, various communication devices include two radio modules that are each implemented to operate in accordance with one particular communication protocol. Alternatively, a multi-protocol capable radio module may support and operate in accordance with more than one communication protocol. Examples of possible communication protocols include those compliant with Bluetooth, IEEE 802.11, and/or 802.15.3c.
