Coaxial RF dual-polarized waveguide filter and method

A device for transmission of wireless signals that performs continuous dynamic frequency selection (DFS), the device comprising:

• radio circuitry configured to transmit radio-frequency signals in a frequency channel from a transmitting reflector and to receive radio-frequency signals from a receiving reflector, wherein the radio circuitry comprises a plurality of transmitters and a plurality of receivers, further wherein the plurality of transmitters are coupled to the transmitting reflector and the plurality of receivers are coupled to the receiving reflector;
• and
• a detector configured to operate concurrently with transmission by the radio circuitry, the detector coupled to either the transmitting reflector or the receiving reflector,
• wherein the device is configured to switch the frequency channel that the radio circuitry transmits on when a radar signal is detected,
• wherein the detector comprises a correlator configured to correlate a received signal with a known radar signal to detect the radar signal.

A device for transmission of wireless signals that continuously monitors a transmitted frequency channel to avoid interference, the device comprising:

• radio circuitry configured to transmit a radio-frequency signal in a frequency channel from a parabolic transmitting reflector and to receive a radio-frequency signal from a parabolic receiving reflector, further wherein the radio circuitry comprises a transmitter and a receiver, wherein the transmitter is coupled to the parabolic transmitting reflector and the receiver is coupled to the parabolic receiving reflector;
• and
• a detector configured to operate concurrently with transmission by the radio circuitry, the detector coupled to either the parabolic transmitting reflector or the parabolic receiving reflector, wherein the detector is configured to continuously monitor the same frequency channel as the radio-frequency signal transmitted by the radio circuitry to detect interference including a reflection of the transmitted radio-frequency signal and a radar signal,
• wherein the device is configured to switch duplexing schemes for the device when the reflection is detected and to switch the frequency channel that the radio circuitry transmits on when a radar signal is detected,
• wherein the detector comprises a correlator configured to correlate a signal received by the detector with the radio-frequency signal transmitted by the radio circuitry to detect the reflection of the transmitted radio-frequency signal.
