1. A mobile device comprising:

  • a sensing circuitry portion configured to operate at a first power level wherein the sensing circuitry portion includes at least one configurable searcher that is operable to sense signals of one or more of a plurality of wireless access technologies supported by the mobile device, where the signals for each of the plurality of wireless access technologies are receivable via a respective wireless chain of a plurality of wireless chains and a baseband processor that are within the sensing circuitry portion and are operable at the first power level; and

    a processing circuitry portion including a primary transceiver and configured to demodulate and decode at least one sensed signal of the one or more of the plurality of wireless access technologies, the processing circuitry portion including the primary transceiver operable at a second power level higher than the first power level of the sensing circuitry portion in the mobile device and the primary transceiver operable for demodulating and decoding the at least one sensed signal.
