ADJUSTMENT OF RADIATION PATTERNS UTILIZING A POSITION SENSOR

摘要

A device for a wireless RF link to a remote receiving device can radiate at different radiation patterns in response to detecting a change in the device position. As the device is moved, displaced, or re-positioned, a position sensor in the device detects the change in position and provides position information to a processor. The processor receives the position information from the position sensor, selects an antenna configuration and physical data rate based on the position information, and provides an RF signal associated with the selected antenna configuration through the antenna elements of the selected antenna configuration.

主权项

1. A method for processing feedback at a wireless device, the method comprising:
computing a respective transmission success ratio based on attempted transmissions of a data packet to a remote receiving node for a plurality of antenna configurations of a wireless device in a first position, wherein each of the plurality of antenna configurations is associated with a different radiation pattern; ranking the plurality of antenna configurations of the wireless device in the first position based on the respective computed transmission success ratios; determining a respective user data rate for each physical data rate of each of the plurality of antenna configurations of the wireless device in the first position; ranking each physical data rate of each of the plurality of antenna configurations of the wireless device in the first position based on the determined respective user data rates; selecting an antenna configuration from the plurality of antenna configurations based on the rankings of the plurality of antenna configurations for the wireless device in the first position; and selecting a physical data rate based on the physical data rate rankings and the selected antenna configuration of the wireless device in the first position.
