Learn how MU-MIMO (Multi-User, Multiple input, Multiple output) can be achieved in a relatively small anechoic chamber and why spatial separation is key to testing. While OFDMA increases the channel access efficiency for a large number of clients, MU-MIMO creates separate spatial channels for each client and boosts aggregated network throughput. The mathematics behind MU-MIMO is complicated and often difficult to understand. This whitepaper uses a simple audio analogy to help the reader visualize what is happening in MU-MIMO channels without reverting to matrices and equations. This understanding helps the reader appreciate the meaning of spatial diversity and helps in the interpretation of results from a real life MU-MIMO test run where we successively connect a number of clients and observe the increases in throughput.

In this 5G tutorial, organized by CN Rood, we discuss essential new test methods for 5G and mmWave.
