Patent ID: 7839805

Claim:
A wireless node, comprising: an antenna; a radio frequency (“RF”) module in communication with the antenna and configured to alternate between down conversion of an incoming signal received by the antenna on a first radio frequency to an intermediate frequency and up conversion of an outgoing signal to a second radio frequency; a first switch coupled to the RF module and configured to select between output of the incoming signal from the RF module and input of the outgoing signal to the RF module; an intermediate frequency (“IF”) module coupled to the first switch and configured to alternate between down conversion of the incoming signal from the intermediate frequency to a base band frequency and up conversion of the outgoing signal from the base band frequency to the intermediate frequency; a second switch coupled to the IF module and configured to select between output of the incoming signal from the IF module and input of the outgoing signal to the IF module; and a modem in communication with the second switch and configured to alternate between demodulation of the incoming signal at the base band frequency and modulation of the outgoing signal at the base band frequency.
