Abstract:
1. A radio frequency (RF) transceiver for Multiple Input Multiple Output (MIMO) communications comprises: a baseband processing module coupled to: convert outbound data into a plurality of outbound symbol streams, wherein each of the plurality of outbound symbol streams is outputted as one or more frames, wherein a frame of the one or more frames includes a setup portion and a data portion, wherein the setup portion includes at least one training sequence field and a signal field, and wherein the setup portion is formatted in accordance with one of a plurality of wireless communication protocols and the data portion is formatted in accordance with another of the plurality of wireless communication protocols; and convert a plurality of inbound symbol streams into inbound data; a transmitter section coupled to convert the plurality of the outbound symbol streams into a plurality of outbound RF signals; and a receiver section coupled to convert the plurality of outbound symbol streams into a plurality of inbound symbol streams, wherein the processing module further functions to: determine the one of the plurality of wireless communication protocols and the another of the plurality of wireless communication protocols based on protocol ordering and protocol utilized by each wireless communication device proximal to the RF transceiver, wherein the protocol ordering includes at least one legacy protocol and at least one more current protocol.
