1. A processing switch configured to receive a first baseband data packet comprising a header including a destination identifier for identifying a destination for the first baseband data packet and a data payload including a baseband input, generate a symbol data packet comprising data symbols by performing at least one orthogonal frequency division multiplexing operation on the baseband input, output the generated symbol data packet from terminals of the processing switch for processing the data symbols in the generated symbol data packet, receive a first set of channel data packets at terminals of the processing switch in response to outputting the generated symbol data packet, each channel data packet of the first set of channel data packets associated with at least one communication channel and comprising at least one processed data symbol, and output the first set of channel data packets.
