Anite has announced today that its Propsim F32 Channel Emulator has been selected by AT4 wireless for its first anechoic MIMO 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 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. MIMO technology uses antenna configurations where both the base station and the device are equipped with multiple transmit/receive antennas.
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.
