Dynamic adaptive and non-adaptive mode switching

1. A method of operating a transceiver, the method comprising:

operating in an adaptive mode in which transmissions from the transceiver are halted after detection of interference;

as a result of the CCA, detecting energy from an interferer above a predetermined threshold;

in response to the detection, switching operation to a non-adaptive mode in which the transceiver is configured to alternate transmission periods and idle periods according to a duty cycle;

subsequent to switching operation to the non-adaptive mode, performing an energy detect;

as a result of the energy detect, subsequently detecting the energy from the interferer below the predetermined threshold; and

in response to the subsequent detection, switching operation to the adaptive mode.
