ABSTRACT:
A system and method comprise a spectrum selector, an unlicensed transceiver, and a licensed transceiver. The spectrum selector determines whether communications will be transmitted over unlicensed spectrum or licensed spectrum. Based upon the determination, the spectrum selector transmits the communications to the unlicensed transceiver or the licensed transceiver. In addition, the spectrum selector may transmit a first portion of the communications to die unlicensed transceiver and a second portion of the communications to the licensed transceiver. On the receiving side, the spectrum selector monitors the unlicensed transceiver and the licensed transceiver, receives the communications from the licensed transceiver and/or the unlicensed transceiver, and transmits the communications to an access device. The unlicensed transceiver transmits and/or receives communications over unlicensed spectrum. The licensed transceiver transmits and/or receives communications over licensed spectrum.
