Abstract

A network device communicates with one or another set of antennas depending on an orientation of the network device. The network device includes a first set of one or more antennas, a second set of one or more antennas, a processor, and memory having stored thereon instructions executable by the processor to cause the device to perform functions. The functions include (1) determining that an orientation of the network device is one of a first orientation and a second orientation; (2) if the determined orientation is the first orientation, then causing the network device to communicate using the first set of one or more antennas; and (3) if the determined the orientation is the second orientation, then causing the network device to communicate using the second set of one or more antennas.
