VIAVI Solutions Inc. announced on February 13, 2025, that its NITRO Wireless test portfolio successfully validated the over-the-air (OTA) performance of the Nokia Massive MIMO radio. This validation was conducted for the radio operating in the upper 6 GHz frequency range, a band crucial for adding capacity to existing cell sites to support 5G-Advanced and 6G networks. The test was a proof of concept established at Nokia's Otava lab in Oulu, Finland.
As 5G applications push current spectrum limits, future wireless technology generations require new frequency bands with requisite capacity, coverage, performance, and efficiency. The allocation of the upper 6 GHz spectrum for mobile services, potentially offering 200 MHz of mid-band TDD spectrum per operator, was agreed upon at the World Radio Conference 2023. Nokia expects operators to increase their TDD mid-band spectrum holdings in the second half of the decade.
The Nokia system under test included a 128TRX Massive MIMO radio based on the Nokia AirScale Habrok platform, configured at the upper part of the n104 band. VIAVI's NITRO Wireless test solution, including the TM500 Network Tester and TeraVM RIC Test, validated upper 6 GHz OTA performance through various test cases. This collaboration reinforces VIAVI's readiness to partner with network equipment manufacturers and operators at every stage of wireless technology evolution.
