Abstract
Radio devices having separate transmission and reception reflectors for transmitting and receiving wireless signals that detect interference in a transmission channel and may be automatically or manually switch duplexing schemes when reflections, radar or other interference is detected. These devices typically include both a transmission antenna reflector and a receiving transmitter reflector, which may be connected or formed of a single housing, that are operatively coupled to radio circuitry for transmission and reception of wireless signals. Interference, and particularly reflected signals between the transmitter and receiver, are avoided by including a detector coupled to either (or both) reflectors that monitors the transmitting frequency channel; reflections and/or radar signals may be detected and may trigger switching (manual or automatic switching) to a different duplexing modes such as frequency-division duplexing (FDD), time-division duplexing (TDD), etc.
