Description

ETS-Lindgren's MIMO OTA Test Systems offer repeatable measurement of radiated performance of wireless devices in a simulated multi-path environment. The system acts as an RF environment simulator that can generate spatial field structures similar to those seen in a wide range of real-world scenarios. Standard conducted channel models can be adapted to equivalent radiated spatial channel models for evaluation of the entire device signal chain, including antennas, device platform, and near field phantom (head, hands, etc.) impact on device performance. The simulated environment is suitable for evaluation of downlink MIMO performance for wireless technologies such as LTE and 802.11n Wi-Fi as well as receive diversity performance of existing wireless technologies per CTIA Test Plan for 2x2 Downlink MIMO and transmit Diversity Over-the-Air Performance Version 1.0.

The system consists of a dual polarized antenna array in an absorber lined fully-anechoic chamber connected to technology specific communication test equipment through a spatial channel emulator. The anechoic chamber provides isolation from interference and reflections in the real-world environment and eliminates unwanted reflections within the test environment.
