Patent ID: 7733981

Claim:
A transceiver, comprising: a transceiver port comprising an antenna for receiving and transmitting wireless communication signals at radio frequency; a receive path coupled to receive ingoing radio frequency (RF) signals from the transceiver port and coupled to produce ingoing digital signals to a transceiver processor; down conversion circuitry disposed within the receive path and coupled to receive the ingoing RF signals wherein the down conversion circuitry produces down-converted communication signals based on the received ingoing RF signals; automatic frequency control circuit that comprises: an RF signal processing portion that supports down converting ingoing signals from RF and up-converting outgoing signals to RF; a first frequency oscillation block generates a local oscillation based upon a frequency specified in a received pilot signal; a first mixing element that mixes a divided oscillation based upon the local oscillation and an oscillation correction signal; a frequency correction block that generates the oscillation correction signal having an oscillating signal form for adjusting a frequency of the divided local oscillation, wherein the oscillation correction signal is based on a difference between a center frequency of the ingoing RF signals and an expected center frequency of the ingoing RF signals; a plurality of amplifiers operably disposed within the receive path including a low noise amplifier operably disposed in the receive path between the transceiver port and the down conversion circuitry; received signal strength indication circuitry for measuring signal and interference power levels from a first node and for measuring signal power levels from a second node; and wherein the transceiver: determines a ratio of the signal power level in relation to the signal and interference power level; and reciprocally adjusts a low noise amplifier gain setting and a gain setting of at least one other amplifier of the plurality of amplifiers operably disposed within the receive path to maintain a constant total gain in the receive path based upon the determined ratio.
