In one illustrative scanning and decoding method, a signal strength level
of an RF signal on an RF channel is measured for a plurality of RF
channels of an RF band. The act of measuring a signal strength level is
repeated at least one time to obtain at least one other signal strength
level of the RF signal. Subsequently, an averaging function is completed
with use of the signal strength level and the at least one other signal
strength level for identifying an averaged signal strength level of the
RF signal. At least one optimal RF signal is then identified based on the
averaged signal strength levels of the RF signals on the RF channels. In
between the repeated acts of measuring signal strength levels of the RF
signals, and prior to identifying the averaged signal strength levels,
control information is decoded on at least one of the RF channels and
stored in memory. A wireless communication network is selected for
communication with use of the control information stored in the memory
which corresponds to one of the at least one optimal RF signal. In this
manner, the mobile station expeditiously obtains the control information
for network selection or other purposes prior to completing the averaging
of the signal strength levels.
