Rohde & Schwarz and 7Layers have verified and validated the synchronized test approach to determine the Envelope Correlation Coefficient (ECC), a value characterizing the antenna subsystem of multiple-input and multiple-output (MIMO) LTE devices. The Synchronized ECC approach delivers significantly shorter test durations and repeatable results, ultimately resulting in reduced costs. Long term, this collaboration will also help product manufacturers develop devices that achieve greater data speeds over LTE by using highly optimized MIMO antenna configurations, the companies said. The Synchronized ECC approach involves over-the-air transfer of measured data between the test platform and a mobile device in a synchronized fashion. This method, proposed by a leading U.S. wireless carrier, does not require any overhead or user interaction to calculate the ECC, making it easier and faster to execute test versus other approaches. 7Layers test engineers used the Rohde & Schwarz TS8991 OTA Performance Test System and software option R&S AMS32-K30 as a test platform for validation. “”7Layers is excited to help bring an ecosystem of vendors together to advance testing of LTE enabled devices utilizing MIMO,”” commented Mahesh Kodukula, business development manager of 7Layers. “”As an accredited test laboratory, we provided a realistic test environment for our partners.”” “”We are pleased to enable this type of testing on our R&S TS8991 OTA test platform and to offer this functionality to a variety of customers that have been waiting for this feature,”” said Thorsten Hertel, OTA product specialist at Rohde & Schwarz. “”We strive to meet the industry needs of the leading edge development of LTE devices.”” Visit Rohde & Schwarz at CTIA 2013, May 21 – 23 at booth 4148 in the Sands Expo and Convention Center, Las Vegas, NV.
