Patent ID: 8874041

Claim:
A method for using an electronic device that has a plurality of antennas to perform system acquisition operations to establish a wireless communications link with a wireless network, comprising: using only a selected one of the antennas to measure received power at each of a plurality of frequencies; identifying which of the frequencies is associated with a largest of the measured received powers; using the identified frequency and the selected antenna to perform system acquisition operations to attempt to establish the wireless communications link with the wireless network; determining whether the system acquisition operations with the selected antenna were successful at establishing the wireless communications link; in response to determining that the system acquisition operations with the selected antenna were unsuccessful at establishing the wireless communications link, switching an additional one of the antennas into use to measure received power in each of the plurality of frequencies; and in response to determining that the system acquisition operations with the selected antenna were successful at establishing the wireless communications link, performing wireless communications over the wireless communications link.
