Bridging the Gap between MIMO Lab and Field Test Results

As the wireless industry works to introduce 4G LTE and WiMAX products and solutions, field testing will be particularly important. The MIMO technology used to enhance system performance and achieve the high data rates expected will cause product performance to vary substantially depending on the RF environment.

Evaluating 4G Performance with New MIMO OTA Test

by John Griesing

A new solution for MIMO OTA testing combines a channel emulator with a reverberation chamber to create a shielded environment for testing EMC and other EM investigations that achieves MIMO throughput performance testing and enables accurate good/bad wireless MIMO device performance prediction.
