Patent ID: 7212586

Claim:
A transceiver, comprising: a transceiver port for receiving and transmitting high data rate communication signals at radio frequency; automatic frequency control circuitry for adjusting a local oscillation frequency based upon a detected difference between an actual frequency of the received communication signals and an expected frequency of the received communication signals wherein the automatic frequency control circuitry produces an adjusted local oscillation; down conversion circuitry to receive the adjusted local oscillation from the automatic frequency control circuitry and further coupled to receive the communication signals at radio frequency wherein the down conversion circuitry is operable to produce base band frequency communication signals based upon the adjusted local oscillation and upon the received communication signals at radio frequency; low pass filtering circuitry coupled to receive the base band frequency signals from the down conversion circuitry, the low pass filtering circuitry for removing a DC offset and low frequency interference to produce low-pass filtered communication signals; high pass filtering circuitry coupled to receive the low-pass filtered communication signals, the high pass filtering circuitry for filtering interference signals that are at a frequency range that is higher than a specified frequency channel of a down converted base band channel; first received signal strength indication circuit for measuring power levels of signal and interference from a node disposed up-stream of the low pass filtering circuitry; and second received signal strength indication circuit for measuring signal power levels from a node disposed down-stream of the low pass filtering circuitry.
