The Building Blocks of a Massive MIMO Test Environment
The cornerstone of a massive MIMO test setup is a channel emulator. The test solution connects a base station with 32 antenna ports to four user equipment (UE) devices, each having two antenna ports. This process requires a PROPSIM F64 channel emulator equipped with 64 RF channels and 512 logical links between the base station and the UE devices when connected bidirectionally.
With a PROPSIM F64-based setup, it is possible to test with commercial devices for both base stations and UEs. The test setup uses test and measurement equipment, such as signal and spectrum analyzers, to monitor system behavior and performance. Combining multiple channels into a single port enhances the capacity of the channel emulator. (See “Introducing Partial Sampling in a Massive MIMO Test Environment,” which describes how to set up a test with combiners.)
