A new over-the-air (OTA) metric called “spherical coverage” is being discussed in 3GPP. The concept is to test the ability of a device to reliably form beams in any direction, offering connectivity in any orientation and polarization. In this paper, we analyze the effectiveness of various test environments for testing spherical coverage at millimeter-wave frequencies for 5G devices.
