5G MIMO OTA Testing FR1+FR2 DC&CC Proposal
Application of 'Close Measurement' Antenna Coupler: Proposal for 4x4 MIMO FR1+FR2 NR-DC&CC in a Desktop Compact OTA Testing Environment.
Morita Tech's 'Desktop-sized Compact OTA Testing Environment for Close Measurement' The terminal side features a desktop-sized compact OTA testing environment capable of testing: - FR1 + FR2 NR-DC (dual connectivity) - FR1 + FR2 NR-CA (carrier aggregation) On the FR1 side, it can accommodate either 4x4 MIMO FA-706S or 8x8 MIMO FR-906S. On the FR2 side, it can support V/H MIMO FA-629S (28GHz), FA-643S (43GHz), 4x4 MIMO FR-729S (28GHz), FA-743S (43GHz), or multiple linear polarized FA-597S (56-75GHz). For simplified testing, FR1 V/H MIMO + FR2 V/H MIMO can be handled with one FA-862S unit. These components are integrated into a compact shielded box FS-1905 for OTA testing.

basic information
The appeal lies in the easy setup that allows for maximum throughput. It eliminates the need for antenna alignment using lasers and the complex installation of antennas in large RF shielded enclosures.

"Nearby Measurement" Antenna Coupler A device for transmitting and receiving in close proximity (compact antenna). A product range that covers frequencies from 600MHz to 70GHz. 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" to maximize the performance of the antenna coupler, the "shield box" that fully demonstrates the capabilities of the antenna coupler (although a radio wave absorber is also used, there is almost no influence from the box walls on the measurements). (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 polarized MIMO, etc.
