1. A method of communication, comprising the steps of:

  • selecting a first carrier frequency within a first frequency band associated with a first multiple access network;

    transmitting a first spread spectrum signal modulated onto the first carrier frequency from a mobile transceiver to the first multiple access network;

    receiving a second spread spectrum signal modulated onto the first carrier frequency at the mobile transceiver from the first multiple access network;

    selecting a second carrier frequency within a second frequency band different from the first frequency band and associated with a second multiple access network;

    transmitting a third spread spectrum signal modulated onto the second carrier frequency from the mobile transceiver to the second multiple access network; and

    receiving a fourth spread spectrum signal modulated onto the second carrier frequency at the mobile transceiver from the second multiple access network.
