VIAVI Solutions Validates Nokia's Massive MIMO for 6G Networks
Validation of Nokia's Massive MIMO Radio Technology
VIAVI Solutions Inc. (NASDAQ: VIAV) has successfully validated the over-the-air (OTA) performance of Nokia's Massive MIMO radio that operates in the upper 6 GHz frequency band. This validation is pivotal for enhancing the capacity at existing cell sites as the industry transitions to advanced 5G and upcoming 6G networks. With the increasing demand for wireless connectivity, this development marks a significant step in meeting future wireless communication needs.
Importance of Upper 6 GHz Band in Wireless Technology
As current 5G applications consume the allocated spectrum, exploring new frequency bands becomes essential. Nokia has shared insights indicating that operators will have to expand their TDD mid-band spectrum holdings in the latter half of the decade. The World Radio Conference 2023 agreed on allocating the upper 6 GHz spectrum for mobile services, which provides a potential 200 MHz of mid-band TDD spectrum designated for each operator.
Proof of Concept Established in Collaboration with Nokia
Nokia and VIAVI set up a proof of concept at Nokia's Otava lab in Finland to thoroughly test the AirScale platform within practical conditions at the upper part of the n104 band, specifically in the range of 6425–7125 MHz. This rigorous testing is essential to validate the system's capacity and to ensure its readiness for real-world operations.
Highlighted Testing Instruments by VIAVI
The testing involved the advanced NITRO Wireless testing solution from VIAVI, which incorporates cutting-edge tools, such as:
- The TM500 Network Tester, renowned among network equipment manufacturers for conducting comprehensive performance assessments of base stations.
- The OneAdvisor 800, a sophisticated spectrum and signal analyzer, crucial for verifying transmitted signals in the downlink and conducting in-depth assessments across 5G channels.
Test Cases Validating OTA Performance
Through this collaborative effort, several test cases affirmed the upper 6 GHz OTA performance, including:
- Peak throughput validation for one and two Component Carriers (1CC and 2CC) alongside downlink and uplink Carrier Aggregation (CA).
- System capacity validation with hundreds of emulated User Equipment (UEs) to mimic real-world data traffic applications.
The Path Forward for 5G and 6G Technologies
This proof of concept is not isolated; it builds upon previous lab configurations and field trials established by Nokia, which centered around validating the OTA performance of the Massive MIMO radio in challenging real-world environments. The results obtained enhance confidence in the technology, paving the way for the development and deployment of future 5G-Advanced and 6G networks.
Industry Perspectives on the Validation
Manuel Mato, Regional Vice President for VIAVI in Europe, the Middle East, and Africa, expressed pride in being part of this significant milestone in wireless technology. The ongoing shift from 4G to 5G and the eventual transition to 5G-Advanced and 6G creates a demand for collaborative efforts among network equipment manufacturers and operators, and VIAVI is committed to aiding this transition.
