Claim Text:
1. A method comprising: receiving a radio frequency (RF) signal; and based, at least in part, on a wireless environment parameter, selectively frequency down-converting said received RF signal to a first intermediate frequency (IF) signal having a first center frequency, and selectively frequency down-converting said received RF signal to a second IF signal having a second center frequency and wherein said second center frequency is greater than said first center frequency; wherein said wireless environment parameter includes a time measurement since a wireless signaling was last detected; and wherein selectively frequency down-converting said received RF signal further comprises: frequency down-converting said received RF signal to said second IF signal when said wireless environment parameter is equal to or greater than a threshold parameter, wherein said threshold parameter includes a maximum wireless signaling time period; frequency down-converting said received RF signal to said corresponding first IF signal when said wireless environment parameter is less than said threshold parameter; switching from the first IF signal to the second IF signal upon detecting occurrence of the wireless signaling; and switching from the second IF signal to the first IF signal upon detecting non-occurrence of the wireless signaling.
