AT4 Wireless Selects Anite’s Channel Emulation Solution for its First Anechoic MIMO OTA Test Laboratory

Anites Propsim F32 Channel Emulators help leading test house perform device testing compliant with upcoming CTIA and PTCRB certification requirements

Anite, a global leader in wireless equipment testing technology, announced today that its Propsim F32 Channel Emulator has been selected by AT4 wireless for its first anechoic MIMO[1] Over-the-Air (OTA) test laboratory in Spain. The laboratory has been set up to perform device testing compliant with CTIA certification requirements prior to market introduction.

AT4 wireless, a leading test house that works with major mobile operators and device manufacturers around the globe, selected Anite’s Propsim F32 for its unique ability to support LTE and LTE-Advanced device testing of up to 32 channels in a single unit, thereby simplifying set-up and reducing cost. Independent test laboratories like AT4 wireless also benefit from Propsim’s superior emulation accuracy and its quicker test execution compared to other solutions available on the market, leading to more reliable test results and quicker device assessment.

The need for MIMO OTA performance testing is expected to increase with the rise of LTE devices containing multiple antennas, which enable mobile device users to access higher data rate services. OTA testing incorporates the device antenna performance by testing a wireless device without any connected cables. Anite’s portfolio of channel emulators is endorsed by all major systems integrators and enables users to comprehensively and quickly verify that mobile devices with multiple antennas meet expected industry requirements in an OTA test set-up.

AT4 wireless has collaborated with Anite since the early 2000s when it started using its protocol signalling device test solutions including SAS (Anite’s interoperability test solution) and Conformance Toolset.

Paul Beaver, Products Director at Anite’s Device & Infrastructure Testing business comments: “AT4 wireless’ selection of Anite for its first anechoic MIMO OTA test laboratory demonstrates our recognised expertise and technology leadership in the field of radio channel modelling.” He continues, “Users benefit from the Propsim F32’s ability to test Carrier Aggregation and MIMO capable devices with large form factors. This combined with the fact that it offers more than twice the emulation capacity compared to other products makes it highly future-proof and suitable for any MIMO OTA application.”

“AT4 wireless is pleased to be working with Anite and to be using its state-of-the-art Propsim F32 in our highly experienced OTA test laboratory, enabling us to fully address the demand for MIMO OTA testing. AT4 wireless continuously invests in test infrastructure to offer our customers leading ‘one stop shop’ services in our EMEA, APAC, North America and Latin American laboratories”, comments Fernando E. Hardasmal, Deputy General Director at AT4 wireless.

¹MIMO (Multiple Input Multiple Output) technology uses antenna configurations where both the base station and the device are equipped with multiple transmit/receive antennas.
