Multiple-Input-Multiple Output (MIMO) technology is the foundation of the new generation of mobile WiMAX products. By leveraging multiple transmit and receive antennas to employ spatial multiplexing, adaptive antenna processing, and space time coding, MIMO products deliver greater wireless throughput and range enabling ubiquitous high-speed voice, video and data services. WiMAX technology being embedded in cellular phones, personal media players, PDAs and laptops as well as service provider networks comes with an expectation of robust testing to ensure the end user’s Quality of Service for real time applications such as voice and video. Furthermore, certification of WiMAX devices requires extensive interoperability and conformance testing.
Robust testing of WiMAX devices includes functionality, performance, conformance, and interoperability testing in conditions that emulate real world scenarios. Comprehensive characterization of a multipath environment is achieved using channel emulation. In-lab controlled channel emulation is required to accurately characterize the effect of multi-channel RF interactions on the conformance, performance and interoperability of WiMAX systems.
