A DISTRIBUTED RADIOHEAD SYSTEM

Various aspects provide a radiohead circuit and a communication device including the radiohead circuit. In an example, the radiohead circuit includes an antenna interface, a radio frequency front end configured to receive a channel scan information including an information related to a target communication channel to be scanned from a communication device processor, perform an energy scan for detecting an activity of the target communication channel based on the channel scan information, generate an activity information including an information as to whether there is the activity on the target communication channel, and provide the activity information to a communication interface; the communication interface configured to couple the processor to a radiohead circuit-external processor external to the radiohead circuit.
