Abstract: A wireless device comprises a plurality of diverse antennas, an accelerometer configured to determine an orientation of the wireless device, and a processor. The processor is configured to initially select a primary link configuration based on the determined orientation of the wireless device. The primary link configuration designates one or more of the plurality of diverse antennas and one or more diverse antennas of another wireless device configured to transmit the payload messages. The processor is further configured to receive payload messages using the primary link configuration, record a received signal strength indication (RSSI) value for the received payload messages, and periodically test RSSI for alternative link configurations. The processor compares RSSI between the primary link configuration and the alternative link configuration, and revises the primary link configuration if the comparison indicates that the alternative link configuration RSSI is greater than primary link configuration RSSI.

Abstract translation: 无线设备包括多个不同的天线，被配置为确定无线设备的方向的加速度计和处理器。 处理器被配置为基于所确定的无线设备的方向来初始选择主链路配置。 所述主链路配置指定所述多个不同天线中的一个或多个以及被配置为发送所述有效载荷消息的另一无线设备的一个或多个不同天线。 处理器还被配置为使用主链路配置接收有效载荷消息，记录所接收的有效载荷消息的接收信号强度指示（RSSI）值，并且周期性地测试用于替代链路配置的RSSI。 处理器比较主链路配置和替代链路配置之间的RSSI，如果比较指示备用链路配置RSSI大于主链路配置RSSI，则修改主链路配置。
