Document Type and Number:
Japanese Patent JP2007116258
Kind Code:
A
Abstract:

To provide a radio communication system for avoiding radio wave interference whereby the PLC is used to reduce interference on each radio system and to keep a radio wave environment excellently, and wasteful power consumption of its own terminal can be suppressed, and to provide electronic equipment.

When a user uses a digital cordless system 100 to start a speech, a digital cordless master unit 100a uses the PLC to inform other systems that its own system starts communication or is during communication. When a wireless LAN system 101 receiving the notice is in standby, a WLAN 101a being an access point of a wireless LAN suppresses an output level of a radio wave to a degree capable of maintaining the link as its control, when the wireless LAN system 101 is during communication, the wireless LAN system 101 informs a laptop PC 101b that the radio output level is decreased, and executes selection processing whereby near distance communication is urged to the user, the communication is interrupted to be in standby, or the communication is completely stopped independently of the situation.
