Abstract
Full-duplex wireless communication enables concurrent transmission and reception over the same radio channel. It thus achieves higher efficiency in spectrum utilization compared with its half-duplex counterpart. In recent years, researchers have built several platforms for full-duplex wireless communications. However, none of these platforms provides full support for full-duplex WiFi, arguably the most popular wireless local-area networking technology. In this paper, we present GRT-duplex, a novel full-duplex wireless platform for the WiFi family, which possesses both flexibility and real-time features. We have also prototyped a full-duplex WiFi instance on this platform, which delivered throughput up to 92.45Mbps, and the frame interaction intervals can be as small as 9.85us.
