Anite (News - Alert), a company that provides wireless equipment testing technology, recently announced that its Propsim channel emulator (Propsim) has been selected by SGS, an inspection, verification, testing and certification company, for its new anechoic MIMO Over-The-Air (OTA) test laboratory in Taiwan. Enhancing SGS’s MIMO OTA testing capacity, the solution will verify the true performance of MIMO and diversity capable mobile devices. It will also help SGS to effectively support the growing demand for LTE (News - Alert) MIMO device testing.
In OTA performance testing, a wireless device is tested without any cables connected to it, thereby incorporating the complete performance of the device, including the antenna RF front end and baseband. By accurately replicating the field propagation conditions of a live network, Propsim creates a realistic RF environment that can be presented to a device within an anechoic or reverb chamber for standardised testing. Propsim is compliant to all draft MIMO OTA testing specifications (related to any planned LTE transmission modes in anechoic chamber system installations) including those published by CTIA (News - Alert), 3GPP and CCSA.
“'SGS's selection of Anite's Propsim demonstrates industry recognition for our leading MIMO OTA testing technology established since 2009,” said Paul Beaver, products director at Anite. “Anite is the only vendor that offers an integrated solution - approved by all major systems integrators - enabling LTE and LTE-Advanced testing of up to 32 channels in a single box.”
In related news, Anite recently announced its Nemo CEM Observer software which seeks to detect the root cause of a customer's dissatisfaction with his or her mobile device by analyzing network parameters that operate at or below layer 3. According to the company's official product announcement, applications may appear to function correctly when parties look only at levels above layer 3. However, such applications may continue to provide users problems due to errors that operate below those levels.
