PROBLEM TO BE SOLVED: To provide an apparatus and methods for low power sensing of wireless access technologies.SOLUTION: A mobile wireless device, such as an access terminal, utilizes a lower power circuitry portion that operates at a lower power than active circuitry, such as a primary transceiver. The lower power circuitry portion includes a searcher that senses if signals of one or more various wireless access technologies are present. When the wireless device utilizes sleep or idle modes for power savings, use of the lower power sensing circuitry to sense the presence of wireless access technologies, rather than using an awoken higher power primary transceiver, affords increased power savings. Putting the lower power circuitry into sleep or idles modes achieves even greater power savings. |
