摘要： A system for pairing wireless nodes includes a plurality of device nodes, such as lamp nodes, a plurality of sensor nodes, such as light switch nodes, and a context manager node. Each of the device nodes, the sensor nodes and the context manager node includes a first communication channel having radio frequency signals and a diverse second communication channel including wireless non-radio frequency signals. Some of the device nodes and the sensor nodes are adapted to collect context information of a corresponding communication environment and to transfer the collected context information to the context manager node. The context manager node is adapted to employ the collected context information and enable automated distributed pairing of a first node of the device nodes and sensor nodes with another second node of the device nodes and sensor nodes.

摘要： A system for assessing wireless communication performance includes a first master wireless node and a number of second wireless nodes. A first schedule of the first node defines transmission and reception of a first set of test packets. A second schedule of the second nodes defines transmission and reception of a second set of the test packets. After start up, each of the second nodes is initialized, and waits to receive a number of the second set of test packets before being synchronized with the second schedule and beginning to receive and transmit the second set of test packets according to the second schedule. First and second processors store data from the first and second sets of test packets, respectively.

摘要： A system includes first and second wireless nodes having a clock with plural times, a wireless transceiver, and a processor cooperating with the transceiver to transmit and receive packets. The second node transceivers wirelessly communicate with the first or other second node transceivers. The second nodes include a Kalman filter with an output, plural filter gains, and an input representing the difference between: about the time of the clock when a received packet should have ideally been received, and a time when the received packet was actually received as measured by the clock. A circuit provides dynamic adjustment of the filter gains. The Kalman filter output estimates the difference between the time of the receiving node clock and a corresponding one of the times of the transmitting node clock. The second processor cooperates with the Kalman filter output to adjust the times of the receiving node clock.

摘要： A commissioning tool includes a laser pointer structured to reflect light from a wireless lighting ballast, a directive antenna, a ranging module structured to determine distance to the ballast, and a housing. The pointer, antenna and ranging module are each mounted in the same common orientation with respect to the housing. A 3D gyroscope determines azimuth angle and elevation angle of the same common orientation. A GPS and dead reckoning system determines the global position of the tool. A wireless transceiver cooperates with the antenna. A processor cooperates with the transceiver to receive a unique device identifier from the ballast. The processor receives the distance, the azimuth and elevation angles, and the global position of the tool, and controls the light source. The processor may output the distance, the azimuth and elevation angles, the global position of the tool and the unique device identifier to another processor.
