EMITE Ing, in co-operation with AT4 wireless, will be the first company to run MIMO OTA throughput tests over the five available LTE terminals worldwide using an E400 mode-stirred reverberation chamber and a recently released E2010 LTE-enabled Base Station Emulator. These tests will be undertaken by the end of the year, and will provide an insight into the behavior of the novel LTE handsets and dongles under a variety of circumstances.

EMITE Ing has developed a technique for the evaluation of diverse MIMO OTA figures of merit including throughput based on a mode-stirred multicavity reverberation chamber, which is a candidate methodology for 3GPP MIMO OTA tests. The co-operation between EMITE Ing and AT4 wireless has generated a high caliber synergy that has allowed the possibility of performing MIMO OTA tests for LTE terminals in an integrated and commercially available solution which conforms to existing 3GPP requirements.

EMITE Ing and AT4 wireless have been engaged to perform a large set of experimental and realistic throughput tests and to provide a proposal for a single and fast figure or merit, based upon throughput, which could clearly distinguish a good 4G MIMO device from a bad one. EMITE’s E400 MIMO Analyzer, in connection with the E2010 Wireless Test Set LTE Base Station Emulator by AT4 wireless, offer a unique integrated solution for LTE MIMO OTA tests.

“The great effort that EMITE has undertaken in the last few years is now paying off. We have received different petitions from different companies worldwide, including a top 5 handset manufacturer, and tests have not even yet started,” said David A. Sanchez-Hernandez, CEO and co-founder of EMITE Ing. “I want to thank all EMITE engineers for their continuous efforts and to AT4 wireless for being able to react rapidly and foresee the possibilities of EMITE in the MIMO OTA testing arena.”
