Abstract:
1. A radio LSI (large scale integration) device comprising: an RF (radio frequency) transceiver unit having a plurality of radio channels; an RF control unit for selecting one of said plurality of radio channels to set the selected channel as a current transmit/receive channel of said RF transceiver unit; and an interfering wave detecting circuit for detecting an interfering wave, using an RSSI (received signal strength indication) signal of said current transmit/receive channel from said RF transceiver unit, wherein said interfering wave detecting circuit includes wherein said interfering wave detecting circuit further comprises a field intensity threshold value register for storing said threshold value such that said threshold value is externally settable, and a duration comparative value register for storing said duration comparative value such that said duration comparative value is externally settable, and wherein said duration comparative value is a time corresponding to twice a packet length of a radio signal transmitted/received over said radio channel.
