FIELD: physics, communications.SUBSTANCE: invention relates to selecting and controlling devices based on wireless communication technology. The wireless controller sends a test message to one or more devices; each device receives the test message, obtains information relating the location thereof relative to the wireless controller, determines the response time according to a first predefined rule based on the relative location information thereof; detects response signals from other devices until the response time expires; decides whether or not to send its response signal according to a second predefined rule and procedure for detecting response signals from other devices; the wireless controller receives response signals sent by devices after comparing information on the location of each device relative to the wireless controller and selects the target device from said devices.EFFECT: reduced complexity, delay and power consumption when selecting wireless devices which are especially applicable for wireless illumination systems.11 cl, 6 dwg |
