Low-Cost, Stable MIMO Test Environment

At evaluation of MIMO communications, reproducibility becomes a problem without control of the over-the-air (OTA) propagation environment, while evaluation using direct cable connections is very different from the actual usage environment. The STACSIM ACC-290/STACSIM-WB ACC-339 with built-in Butler Matrix Module provide an easy, low-cost implementation for the 4x4 MIMO propagation environment.

Spider SPI-100 series

Spider™ is an automated Static Channel Emulator featured modular, scalable, and cost-effective. The Spider™ provide controllable 4x4 MIMO links in a variety of topologies (Standalone, Star 2/3 node, Mesh) with complete RF isolation for a test under End-to-end connections between multiple devices. Typical application will be for LTE unlicensed, IoT (e.g. Drone), and 802.11ac with use cases such as mobility, handover, radio coexistence testing. In addition, users can create their own solutions using the Spider platform and the modules available in the Director-II test executive.
