When it comes to OTA testing for 5G/local 5G, it's Morita Tech.
We have prepared "presentation materials" that propose detailed OTA testing methods. Please feel free to download the presentation materials, catalogs, etc.
Various wireless devices, such as 5G, are shifting from traditional coaxial cable connection testing methods to OTA (Over The Air) testing. - Space-saving OTA testing - OTA testing on the manufacturing line - Testing various frequencies in a single shielded box, such as 700MHz, 3.7GHz, 4.5GHz, and 28GHz - Conducting "interoperability testing" with multiple vendors - Performing handover testing - Conducting carrier aggregation testing - Performing MIMO testing with 4x4 or more Antenna couplers and their application products (compact OTA testing environments) are solving these challenges.
basic information
The "near-field measurement" antenna coupler is a near-distance transmission and reception device developed by Morita Tech, which has obtained international patents. - It can be installed in close proximity to the object being measured (wireless terminal). - It features a flat frequency characteristic (S21/S11) across a wide bandwidth. - The antenna coupler can be installed near the device. - OTA testing can be conducted within a small shielded box, eliminating the need for large facilities like a large anechoic chamber using horn antennas or pyramid-shaped wave absorbers. - The "OTA testing environment" using the antenna coupler has also obtained international patents. - In 5G, it can operate LTE, Sub6GHz, and millimeter wave (28GHz) in a single OTA environment (shielded box). - MU-MIMO (Multi-User MIMO) testing can also be conducted in a single OTA environment. - Interconnectivity tests and other evaluations can be performed in a compact environment (for telecommunications carriers).
