SUNNYVALE, Calif. -- Spirent Communications, a leader in wireless networks, services and devices testing, today introduced its next-generation solution for testing MIMO-based wireless base stations and mobile devices. The VR5 HD Spatial Channel Emulator addresses the increased complexity of MIMO technologies such as LTE and LTE-Advanced, which rely on large numbers of antennas, higher bandwidth, and band aggregation to deliver high-speed data. The Spirent system embodies groundbreaking concepts in both hardware and software used for wireless testing.

"Testing cutting-edge MIMO receivers requires a large number of synchronized RF channels," said Stephane Teral, principal analyst, service provider mobile and FMC infrastructure at Infonetics Research. "The 8x4 TD-LTE research currently being performed in China is a great example. MIMO Over-the-Air (MIMO-OTA) testing is another. The ability to create these intricate RF test cases in a single bench-top unit can have a direct effect on the efficiency and cost of testing."

The VR5 HD Spatial Channel Emulator's software implements an innovative touchscreen interface, developed specifically for intuitive control of complex MIMO systems. With a few finger-strokes, test engineers can set up scenarios involving literally dozens of radio channels. The interface also provides step-by-step graphical feedback during setup and execution, so that any missteps are quickly caught and corrected.

"This unprecedented level of test integration demands a new way to control it, so the VR5's touchscreen GUI was built on a completely user-oriented design philosophy," said Rob VanBrunt, vice president of Spirent's Wireless group. "Now, even the least-experienced user can run complicated handover and bi-directional testing quickly and accurately while reproducing the realistic performance of a deployed system."
