Abstract:
A device that dynamically selects between multiple antennas to provide a best antenna selection for a wireless link between the device and an access point. The device may have a switch connected to multiple antennas and may instruct the switch to select from the antennas in order to improve a signal quality of the wireless link regardless of orientation of the device or obstructions in proximity to the device. For example, the device may determine a first signal strength associated with the wireless link using a first antenna and a second signal strength associated with the wireless link using a second antenna and may select the first antenna or the second antenna based on the first signal strength and the second signal strength.
