The RayZone-2800 from General Test Systems is a MIMO OTA Test System for wireless and cellular applications from 400 MHz to 6 GHz. It supports 2G/3G/4G/4.5G/5G Wi-Fi, GPS, and NB-IoT/eMTC standards. This chamber/system measures 3 x 3 x 2.9 meters and can be used to conduct true 3D MIMO OTA testing for both 2×2 and 4×4 configurations. It can measure various antenna parameters such as: gain, directivity, beamwidth, cross-polar level, sidelobe level, efficiency, etc. The chamber provides over 90 dB of shielding. The RayZone-2800 is easy to install/reassemble/relocate and requires an AC source of 220V/110V.
