Anritsu and EMITE announced that the Anritsu MT8820C radio communication tester has been successfully used in combination with the EMITE E500 reverberation chamber and Anite Propsim FS8 channel emulator to test LTE carrier aggregation, using 2×2 MIMO and more realistic isotropic Urban-Macro (UMA) fading profiles. The tests were performed for a leading U.S. carrier.
“We are very happy to have Anritsu’s excellent MT8820C base station emulators integrated in our MIMO OTA Carrier Aggregation RC+CE test platform, as this will certainly add value to our customers,” said David Sanchez-Hernandez, CEO and cofounder of EMITE. “Being able to test LTE CA + MIMO + UMA with a variety of auxiliary equipment units is a novelty worldwide, and brings MIMO OTA testing to a higher level of realism and applicability worldwide.”
The MT8820C LTE one-box tester is a multi-format 2G, 3G, and LTE tester with capability for UE calibration, RF parametric testing, and functional testing, including call processing or no-call-based testing. Supported formats include LTE-A, LTE, W-CDMA/HSPA CDMA2K up to 1xEV-DO rel. A, TD-SCDMA/HSPA, and GSM/GPRS/EGPRS. The MT8820C provides the most stable and most widely proven implementation of cellular standards for base station emulation and “call box” testing.
EMITE’s unique multicavity mode-stirred source-stirred reverberation chamber solutions (MSRC) provide for a variety of fading scenarios at a fraction of the cost of alternative anechoic chamber-based test solutions. Along with conventional uniform, isotropic Rayleigh and more complex SCME-based fading profiles for MIMO OTA testing, the EMITE solutions are the only ones also offering other standardized fading profiles using the patented Sample Selection technique.
EMITE is a spin-out of the Technical University of Cartagena (Spain), awarded with the Spanish Emprendedor XXI Award and Certified by Spanish ANCES as Innovative High-Tech Company (EiBT), with headquarters at the Fuente Alamo High Tech Park in the Region of Murcia (Spain). EMITE designs, develops, manufacturers, and commercializes MIMO analyzers as mode-stirred source-stirred reverberation chambers for the compliance testing of diverse 3G and 4G standards and pre-standards worldwide, including LTE, Wi-Fi a b g n ac, WiMAX, and HSPA+, and has distribution offices in the U.S., Canada, Israel, South Korea, China, Taiwan R.O.C., Singapore, and Japan. EMITE’s MIMO OTA mode-stirred source-stirred reverberation chamber solutions were selected by 3GPP and CTIA as candidate methodology for standardized LTE MIMO OTA compliance testing.
