WLAN MIMO Device Performance Evaluation Using Improved RTS Measurement

This work demonstrates a measurement-based method to evaluate the throughput performance of wireless local area network (WLAN) devices. The implementation is mainly based on an improved radiated two-stage (RTS) method independent of the request of reception. In this method, the antenna patterns are achieved using the reciprocal channel transmitting and receiving property, while the normal reception information for throughput evaluation is obtained by the amplitude comparison algorithm. Compared with the traditional RTS method and the test method in real scene, the whole throughput measurement can be realized without the special reception request from user equipment, while the channel models simulating the working circumstance can still be applied in constructing comparable test circumstance to save cost. The experimental demonstration proves, for WLAN multiple-input–multiple-output (MIMO) device, that the proposed test method can achieve a comparable test performance with the traditional test method under real scene, while the test time is shortened and the test cost is reduced.
