Devices for coexistence of transmitters and receivers operating based on different wireless protocols
A device including a transmitter, a receiver and an arbiter. The transmitter transmits a first signal. The first signal has a fundamental frequency in a first frequency band of a first wireless protocol. The receiver receives a second signal. The second signal has a fundamental frequency in a second frequency band of a second wireless protocol. The first frequency band is adjacent to or at least partially overlaps the second frequency band. The arbiter allows the transmitter to transmit the first signal in the first frequency band while the receiver receives the second signal in the second frequency band. The arbiter also, if a power level of the first signal is less than a first threshold, changes: a modulation and coding scheme of the transmitter for the first signal; a modulation and coding scheme of the receiver for the second signal; or a multiple input and multiple output rank.
