Design and Prototyping of 60 GHz Mesh Networks

We present a new design of a 60 GHz mesh networks based on IEEE 802.11ad. By using an edge/vertex-coloring algorithm to carefully allocate the channels in the mesh network, the co-channel interference of the mesh network, particularly intra-node interference, can be significantly reduced. In our prototype, we found that with 90° angle separation, there is negligible intra-node interference and rate loss. Furthermore, our indoor demonstrations with multi-hop transmissions showed that end-to-end throughput as high as 1.7 Gbps can be achieved.
