Modeling and Characteristics Analysis of Indoor Wireless Channel at 11 GHz with Pedestrian Influence
To study the channel propagation characteristics of high frequency broadband short range wireless communication, the wireless propagation characteristics of different indoor scenarios at 11 GHz are measured.Based on a large amount of data, a path loss ( PL ) model with pedestrian factors is established, and the statistical characteristic of root mean square delay is presented.In addition, the influences of pedestrian factors on channel propagation characteristics in corridor, classroom and large conference room are compared and analyzed.The research results show that when the pedestrian moves between the transmitter and receiver, the PL caused by pedestrian blocking factors has a quadratic function relationship with the distance between the pedestrian and transmitter.When the pedestrian is stationary, the PL caused by passer-by is an exponential function of their distance from the receiving end.Moreover, the impact of pedestrian on path loss varies in different scenarios, and the pedestrian factors also enhance the multipath effects.The above research results can provide theoretical and practical basis for the application of high-frequency indoor short-distance wireless communication in the future.
