The Taiwan National Chiao Tung University (NCTU), with a dedicated 4G LTE Broadband Mobile Lab, has selected Anite’s Propsim radio channel emulator for its MIMO Over-The-Air (OTA) testing system.

MIMO, a key feature of LTE, introduces complex radio conditions leading to new challenges within development, testing and performance optimisation of mobile devices. In order to achieve accurate results, performance testing of MIMO enabled mobile devices needs to be conducted under realistic, repeatable and controllable radio channel conditions. Anite’s Propsim channel emulator enables NCTU to simultaneously and reliably test all parts of the TD-LTE mobile device that impact the end-user experience (antennas, RF front end and baseband processing).

The Propsim®radio channel emulators are designed to replicate wireless environments and isolate performance issues in order to ensure the reliable functionality of any broadband wireless technology, such as TD-LTE.

“The Propsim radio channel emulator is a core part of our MIMO OTA testing system.” said I-Wei Chen, Executive Director of Broadband Mobile Lab at NCTU. “One of our key goals is to set up a very close-to-reality lab environment for testing LTE devices in order to reveal the true performance experienced by the end-user. Anite’s Propsim channel emulator perfectly matches our requirements by providing accurate and repeatable fading channel emulations.”

“We are delighted to see leading laboratories such as NCTU carry out true MIMO OTA testing of TD-LTE devices through the use of our Propsim channel emulators,” said Paul Beaver, Anite’s Product Director. “TD-LTE device manufacturers in Taiwan can now perform pre-testing domestically, which will greatly help to speed up development of new TD-LTE capable mobile devices.”
