Small OTA testing environment for interoperability testing in O-RAN multi-vendor scenarios.
In local 5G, multi-vendor base stations by the O-RAN Alliance are becoming mainstream. They are suitable for interoperability testing and operational testing.
Morita Tech's "Desktop-sized Compact OTA Testing Environment for 'Measuring Nearby'" is just right for hardware and software engineers working with 5G and local 5G! It allows for verification, tuning, and software modifications in OTA testing using real radio waves, all in a space-saving manner. We already have numerous adoption records with telecommunications carriers, local 5G operators, manufacturers, etc. (interconnection testing labs, open labs, app bearer verification departments, etc.) - KDDI / NTT Docomo / Softbank / Rakuten - NTT East Japan / NTT West Japan - The University of Tokyo - Numerous base station and terminal manufacturers In local 5G, customization of base stations to accommodate a wide variety of devices that differ with each implementation project is essential. OTA testing to verify the implementation of "network slicing" and "QoS" using real radio waves is unavoidable. Our solution eliminates the need for testing in radio anechoic chambers or large radio test boxes, and allows for testing items that are difficult to conduct in such facilities. By "measuring nearby," we propose a "compact OTA testing environment" that significantly reduces development costs, shortens development periods, and saves space.

basic information
In 5G/local 5G, the multi-vendorization of RU/DU/CU through O-RAN (OpenRAN) is rapidly progressing. The importance of interoperability testing with various combinations is increasing. This document proposes a "compact OTA testing environment" using an antenna coupler that allows for space-saving and compact equipment testing in an OTA environment.

Detailed information
-
"Nearby Measurement" Antenna Coupler A device for transmitting and receiving at close range (compact antenna) A product range covering frequencies from 600 MHz to 70 GHz. The small antenna couplers with 1, 2, 4, and 8 ports are essential devices for conducting MIMO tests within a compact shielded box. This is an internationally patented product.

"Measuring nearby" maximizes the performance of the antenna coupler, utilizing a "shield box" that fully demonstrates the capabilities of the antenna coupler (although a radio wave absorber is also used, the influence from the box walls is almost negligible. This product has obtained an international patent as a compact OTA testing environment using an antenna coupler). - Interconnectivity testing - Beamforming testing (FR2 millimeter wave) - Testing with MU-MIMO, SU-MIMO, and polarization MIMO, etc.
