Smart antenna system using orientation sensors

摘要

A wireless device comprising an antenna subsystem having a selectable polarization, at least one sensor configured to provide at least one orientation measurement of the wireless device, and a processor unit coupled to the at least one sensor and configured to receive the at least one orientation measurement, select a polarization of the antenna subsystem based on the at least one orientation measurement, and set the polarization to achieve the selected polarization.

1. A wireless device comprising:
an antenna subsystem having a selectable polarization; at least one sensor configured to provide at least one orientation measurement of the wireless device and provide an indication of an environment of the wireless device; a memory configured to store polarization information for different states of the antenna subsystem; and a processor unit coupled to the memory and configured to:
receive the at least one orientation measurement;select a polarization of the antenna subsystem based on the at least one orientation measurement and the polarization information for the different states of the antenna subsystem from the memory when the indication of the environment comprises the wireless device being in an outdoor environment;select the polarization of the antenna subsystem based on a received signal strength when the indication of the environment comprises the wireless device being in an indoor environment, wherein the received signal strength is measured using different antenna subsystem configurations; andset the polarization of the antenna subsystem to achieve the selected polarization.
