Anritsu and EMITE have used the Anritsu MT8820C radio communication tester in combination with the EMITE E500 reverberation chamber and the Anite Propsim FS8 channel emulator to test LTE carrier aggregation, using 2x2 MIMO and more realistic isotropic urban-macro (UMA) fading profiles. The tests were performed for a leading US 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 co-founder 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 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 standardised fading profiles using the patented Sample Selection technique, something unheard of in the wireless arena until now.
