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.
