Abstract:
Embodiments include methods of testing wireless devices for beam forming performance. Various aspects may include determining measurements of communication performance of the wireless device at each of a number of different angular orientations of the wireless device with respect to an antenna within a test chamber, and determining whether the wireless device satisfies beam forming performance requirements by comparing the measurements of communication performance to pass/fail criteria. Further embodiments may include a wireless device testing apparatus configured to perform testing wireless devices for beam forming performance. In some embodiments, a wireless device testing apparatus may include a test chamber, an antenna within the test chamber, a rotatable positioning system within the test chamber configured to hold a wireless device and rotate the wireless device within a range of orientations with respect to the antenna, and a computing device coupled to the antenna and the rotatable positioning system.
