Cobham Wireless has delivered its Massive MIMO (Multiple-In-Multiple-Out) test solution to China Mobile Research Institute, to enable the operator to benefit from the capacity and performance gains of digital Massive MIMO technology.
The concept of digital Massive MIMO has been introduced in 4.5G technology, vastly improving network capacity and energy efficiency by increasing the number of data signals that can be sent and received. The technology can improve end-user experience by directing signal to areas where there is high-bandwidth demand, and away from areas where less energy is required. However, testing the performance of multiple signals remains a big challenge for the industry.
To address this, Cobham Wireless has worked together with China Mobile Research Institute and developed a scalable, multi-beam Massive MIMO performance test solution. It offers a cost effective and efficient way to validate Massive MIMO core technologies and system functions. It involves testing the technology in a virtualised environment that can simulate hundreds of real world conditions and different beam-based capacity performance scenarios. The solution sets the benchmark for 5G Massive MIMO lab testing, which until now has consisted of simple capacity or limited-scale performance scenarios. The innovative approach to test the Massive MIMO will facilitate to shorten the time to market of 5G NR products for field trial and the later commercial launch.
