CHANDLER, Ariz., Feb. 13,
2025 /PRNewswire/ -- VIAVI Solutions Inc. (VIAVI)
(NASDAQ: VIAV) today announced that its NITRO® Wireless
test portfolio has validated the over-the-air (OTA) performance of
the Nokia Massive MIMO radio operating in the upper 6 GHz frequency
range, a band that will add crucial capacity to existing cell sites
to support 5G-Advanced and 6G networks.
As 5G applications push the currently allocated spectrum to its
limits, a key focus for future generations of wireless technology
is to enable use of new frequency bands with the requisite
capacity, coverage, performance and efficiency. According to Nokia,
operators will need to increase their TDD mid-band spectrum
holdings during the second half of the decade. The allocation of
the upper 6 GHz spectrum for mobile services, which means a
possible 200 MHz of mid-band TDD spectrum per operator, was agreed
upon at the World Radio Conference 2023.
To test performance of the AirScale platform in the upper 6 GHz
band in replicated real-world scenarios, Nokia and VIAVI
established a proof of concept at Nokia's Otava lab in Oulu,
Finland. The Nokia system under
test included a 128TRX Massive MIMO radio based on the Nokia
AirScale Habrok platform, configured at the upper part of n104 band
(6425–7125 MHz).
The NITRO Wireless test solution provided by VIAVI included:
- TM500 Network Tester, the flagship platform used by network
equipment manufacturers worldwide for early functional, system
integration, capacity, performance, and regression testing of base
stations.
- OneAdvisor 800 spectrum and signal analyzer, to verify signals
transmitted in the downlink for conformance testing and analysis of
the 5G channels, including RF characterization, beamforming, timing
and synchronization over the air and overall radio base station
transmission performance.
The following test cases validated upper 6 GHz OTA
performance:
- Spectrum analysis and peak throughput validation of one
Component Carrier (1CC), and two Component Carriers (2CC)
with downlink and uplink Carrier Aggregation (CA)
- Performance and capacity validation with hundreds of emulated
User Equipment (UEs) and real-world data traffic applications.
This proof of concept built on previous lab and field trials
conducted by Nokia, focusing on OTA performance of the Nokia
Massive MIMO radio in the upper 6 GHz band under real-world
conditions, and further validating its capability to support
development and deployment of 5G-Advanced and 6G networks.
"VIAVI is honored to have been selected for such a
groundbreaking milestone in wireless technology," said Manuel Mato, Regional Vice President, Europe
Middle East and Africa, VIAVI. "As
the industry continues to transition from 4G to 5G, and on to 5G-A
and 6G, VIAVI is ready to partner with network equipment
manufacturers and operators at every stage."
