Spirent and ETS-Lindgren Collaborate to Advance Mobile Device RF Testing
Mar 23, 2011
New Alliance Streamlines MIMO Over-the-Air Testing
Sunnyvale, Calif. and Cedar Park, Texas – March 23, 2010 — Spirent Communications, a leader in testing wireless networks, services and devices, and ETS-Lindgren, a leading supplier of test systems, services and anechoic chambers, today announced their collaboration to advance Over-The-Air (OTA) test methods for mobile devices.
The collaboration brings together ETS-Lindgren’s anechoic chamber expertise with Spirent’s unique capabilities in the area of wireless RF channel modeling, integrating Spirent’s MIMO-OTA Environment Builder and Spirent’s channel emulation capabilities with ETS-Lindgren’s AMS-8700 and AMS-8900 series Multiple-In Multiple-Out (MIMO) OTA Environment Simulation Systems.
MIMO antenna techniques are used in wireless technologies such as LTE. The purpose of such an approach is to extend data speed capabilities without requiring additional wireless spectrum. MIMO-OTA testing uses channel emulation equipment and anechoic chambers to create live RF environments that enable testing under controlled over-the-air conditions, allowing designers to maximize the data performance of MIMO-equipped mobile devices.
“The collaboration with ETS-Lindgren makes use of our MIMO-OTA Environment Builder, which brings an important new capability to both our SR5500 Wireless Channel Emulator and our new VR5 HD Spatial Channel Emulator,” said Rob VanBrunt, vice president, Wireless group at Spirent. “In fact, a key goal of the VR5 HD development was to create a single bench-top unit that could easily and accurately manage the most demanding MIMO-OTA test cases. The Environment Builder uses a graphical interface that makes set up of these test cases easy, in contrast to earlier approaches which were extremely complicated.”
“Spirent’s contributions to the development of MIMO-OTA testing have been invaluable to the industry,” said Bryan Sayler, a senior vice president ETS-Lindgren. “We’re very pleased to be working with them, and we’re excited about the capabilities offered by their MIMO-OTA Environment Builder.”
Spirent and ETS-Lindgren experts will also be taking part in a key panel discussion - Understanding MIMO OTA Testing - at the International CTIA Wireless 2011 event in Orlando on March 24. For more information visit: http://www.ctiawireless.com/events/eventdetails.cfm/1256.
