1. An apparatus, comprising:

  • a spatially diverse antenna array of M antennas, where M is greater than or equal to two;

    at least one multiple-input and multiple-output/orthogonal frequency division multiplexing-capable transceiver in communication with the spatially diverse antenna array of M antennas;

    encoding circuitry capable of causing first data to be encoded;

    decoding circuitry capable of causing second data to be decoded; and

    processing circuitry in communication with the at least one multiple-input and multiple-output/orthogonal frequency division multiplexing-capable transceiver, the encoding circuitry, and the decoding circuitry, the processing circuitry capable of causing the apparatus to;

    link to a plurality of multiple input-capable nodes including a first multiple input-capable node and a second multiple input-capable node, by;

    linking to the first multiple input-capable node utilizing a first diversity channel at a particular time and utilizing a particular frequency resource, using a space-division multiple access protocol, andlinking to the second multiple input-capable node utilizing a second diversity channel at the particular time and utilizing the particular frequency resource, simultaneously with the linking to the first multiple input-capable node utilizing the first diversity channel, using the space-division multiple access protocol;

    receive information from at least one of the plurality of multiple input-capable nodes, the information including weight-related information, the information further including channel-related information that is based on a signal to interference and noise ratio;

    determine weights;

    apply the weights to transmit data;

    add a cyclic prefix to the transmit data; and

    multiplex the transmit data with at least one pilot signal;

    wherein the apparatus is configured such that the at least one multiple-input and multiple-output/orthogonal frequency division multiplexing-capable transceiver is capable of causing transmission of at least one transmit signal including at least a portion of the transmit data and at least a portion of the at least one pilot signal to at least one of the plurality of multiple input-capable nodes, such that at least one aspect of the at least one transmit signal is based on at least a portion of the information, and the at least portion of the transmit data is transmitted with a specific frequency resource to the at least one multiple input-capable node utilizing a plurality of different diversity channels;

    wherein the apparatus is configured so as to dynamically change a transmit channel to another channel different from a previous channel utilized in connection with the at least one multiple input-capable node;

    wherein the apparatus is further configured so as to dynamically route via another route different from a previous route, utilizing another node and a different link;

    wherein the apparatus is further configured such that the dynamically routing utilizing the another node includes routing as a function of an interference associated with at least one link associated with the apparatus.
