Abstract
Systems and methods for design and testing of RF components are described. One or more RF isolation chambers are used to house MU-MIMO capable devices under test, including wireless access points and client devices. Spatial and angular positioning of the antennas within a chamber and controlled power of the signals into each antenna via RF combiners and RF attenuators to achieve a controllable apparent/virtual angular spread among the respective client device signals is described.
