摘要： An antenna orientation adjustment device (200) include a camera (210), nut runners (220 and 230), and a motion controller (400). The nut runners (220 and 230) can be mounted on an azimuth adjustment bolt (160) and an elevation adjustment bolt (180), respectively. The nut runners (220 and 230) change the orientation of an antenna unit by applying motor power to the azimuth adjustment bolt (160) and the elevation adjustment bolt (180). The motion controller (400) calculates an angle position of the antenna unit (110) where a reception strength is maximum based on an image taken by the camera (210) and a reception strength of radio waves received by the antenna unit (110), and then adjusts the antenna unit (110) to the angle position where the reception strength is maximum by supplying a drive signal to the azimuth adjustment bolt (160) and the elevation adjustment bolt (180). Any worker can thereby quickly and accurately install the antenna device.

摘要： An electronic device modifies a schedule of communication frequencies (such as an orthogonal frequency division multiplexing access schedule) by changing the times when subcarriers are used for communication with a set of electronic devices in order to cluster subsets of the set of electronic devices. This clustering may leave the throughput associated with the communication at least approximately unchanged. Then, the electronic device selects, for the subsets, transmit antenna radiation patterns and receive antenna radiation patterns in order to increase the throughputs during transmission and/or receiving.
