A full characterization of the wireless communications channel is critical for defining system performance limits when developing a new technology and creating test metrics for throughput testing of an existing technology.

The development and deployment of next generation devices greatly depends on the ability to test and analyze the devices under realistic conditions. Using MIMO-OTA channels, a small anechoic chamber and with proper placement of probe antennas, testing can be conducted in a more cost-effective way for the ever emerging Wi-Fi and LTE standards developed by the 3rd Generation Partnership Project (3GPP).

This whitepaper provides an overview of the characterization of a near-field MIMO communications channel and propagation between the transmitter and receiver and how this is accomplished by the use of probe antennas.
