ETS-Lindgren's AMS-5709 FR2 MIMO OTA Antenna Measurement System allows repeatable measurement of radiated performance of millimeter wave wireless devices and chipsets in a simulated multi-path environment in order to emulate real world conditions for debugging, and performance verification.


The system supports generation of spatial field structures similar to those seen in a wide variety 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, and device platform on device performance.


The system can be equipped with any combination of optional Test Packages to evaluate downlink FR2 MIMO performance, and FR2 MIMO antenna design.

Product Details
Product Features
Test Enclosure
The system acts as a mobile (on wheels) 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, and device platform impact on device performance. The simulated environment is suitable for evaluation of downlink MIMO performance as well as receive diversity performance for millimeter wave NR.

Antenna Array System
The multi-antenna array includes dual-polarized antennas mounted to the interior of the MIMO antenna structure via custom fixtures. The array is configured with RF-cables routed from the antennas back to the connector panel. RF-cables are also provided outside the chamber to connect each probe within the chamber to the frequency converters and communication test equipment through a radio channel emulator(s).

Via the channel emulator the antenna array transmits downlink signals from a range of Angles of Arrival (AoA), simulating the scattered reflections seen by a wireless device in normal operation. The channel emulator(s) uses specially-modified spatial channel models to feed each antenna in the array with a statistical sampling of the source signal(s) with appropriate doppler and delay spreads to emulate the scattering effect of fixed and moving objects within the simulated environment.

Positioning System
A dual axis positioning system allows the DUT to be rotated through the generated field structure to determine its relative performance in different orientations within the simulated environment.

EMQuest Data Acquisition Software
EMQuest FR2 MIMO OTA Test Option adds a suite of test capabilities to the EMQuest EMQ-100 Antenna Measurement Software. These include specialized tests for evaluating the throughput of a wireless device in the simulated environment, as well as R&D tests to allow evaluation of antenna correlation and system calibration and validation tests.
