Abstract: There is described a lighting control system of a building environment comprising a control device and a lighting device. The control device is capable of detecting an activation of a configuration mode of the lighting control system and controlling illumination for the building environment in response to command inputs received at a user interface. The lighting device is capable of receiving a message indicating that the activation of the configuration mode has been detected by the control device and receiving a directional signal from a directional device subsequent to receiving the message. A membership status of the lighting device in a device group is changed in response to receiving the directional signal.

Abstract: A transmitter including a plurality of transmitting antennas and a processor operably coupled to the plurality of transmitting antennas. The processor is configured to select a first antenna from the plurality of transmitting antennas for transmission of a frame of data, determine if the frame is successfully received by a receiver, and select a second antenna different than the first antenna from the plurality of transmitting antennas for retransmission of the frame if it is determined that the frame was not successfully received by the receiver. The processor is configured to select a different antenna than a previous antenna for retransmission of the frame each time it is determined that the frame was not successfully received by the receiver. The processor is configured to discard the frame from further transmission if it is determined that the frame was not successfully received by the receiver after a number of transmission attempts.

Abstract: In a wireless local area network which includes access point having variable transmitter power levels, transmitter power data is sent from the access points to the mobile units and used by the mobile units in order to provide a corresponding variation in the transmitter power of the mobile unit.
