The performance requirements of new mobile terminals will continue to increase dramatically due to the growing demand for higher data-rate applications. To meet this increased end-user performance requirement, new mobile terminals are being developed using the recent advances in the multiantenna Multiple Input-Multiple-Output (MIMO ) technique. In testing of such MIMO mobile terminals, including the antenna effects is crucial to ensure end-user quality of service.

MIMO Over-the-Air (OTA) testing is a new testing method that provides the possibility to test the true mobile-terminal performance without using artificial cabling in the test setup. All testing is done over the air with the final product components untouched. MIMO OTA testing is the only way to truly evaluate the end-user experience of the final product, such as data throughput, against realistic radio channel conditions. This White Paper discusses this new opportunity and introduces the MIMO OTA testing method for MIMO mobile terminal testing.

We are presenting this White Paper as a pdf document (no registration required) in three parts:

  • Part 1: Abstract, Table of Contents, and Introduction, click here.
  • Part 2: From SISO Conductive testing to MIMO OTA testing; MIMO OTA Testing Method, click here.
  • Part 3: Summary, EB OTA MIMO Concept, and References, will be posted February 1, 2010.
