1. A method of switching radio connections in a communication system, comprising:

  • providing a peripheral node comprising a first set of radios for transmitting and receiving signals, wherein the first set of radios of comprises a plurality of radios having complementary characteristics and different structures;

    providing a base node comprising (1) a second set of radios for transmitting and receiving signals, wherein the second set of radios comprises a plurality of radios having complementary characteristics and different structures, wherein the peripheral node and the base node are constructed and arranged to wirelessly connect via both the first set of radios and the second set of radios, and (2) a controller configured to assess a quality of a wireless connection and send commands to the plurality of radios in the first set of radios and the second set of radios to activate or deactivate in real time based on the quality assessment;

    activating the wireless connection between the base node and the peripheral node by selecting a first radio from the first set of radios and a first radio from the second set of radios to form a forward radio connection that transmits data from the peripheral node to the base node;

    forming a reverse radio connection that transmits data from the base node to the peripheral node using a selected radio from the first set of radios and a selected radio from the second set of radios; and

    switching to a second radio from the first set of radios and a second radio from the second set of radios to maintain the forward radio connection during the wireless connection, in response to the commands from the controller provided through the reverse radio connection.
