ANTENNA SELECTION BASED ON ORIENTATION, AND RELATED APPARATUSES, ANTENNA UNITS, METHODS, AND DISTRIBUTED ANTENNA SYSTEMS

摘要

Antenna apparatuses and related antenna units that include antenna selection based on orientation are disclosed. Related methods and distributed antenna systems are also disclosed. Antenna selection is provided between two or more antennas disposed in different polarization orientations according to orientation of the antenna unit in which the antennas are included. The antenna(s) oriented most closely to perpendicular to the ground in one embodiment may be selected for use in wireless communications with wireless client devices. In this manner, the antenna(s) employed in wireless communications is likely to be the closest in polarization to the polarization of wireless client device antennas. Otherwise, an unacceptable reduction in communications link quality with the wireless client devices may occur.
