UWB 2D communication tiles

This paper proposes “2D communication (2DC) tiles” for practical implementation of UWB 2D communication. Each tile is a 50-cm square which is the standard size of carpet tiles. The tiles can be easily connected and the covered area is extendable freely. If the surfaces of the desks, walls and floors have 2DC tiles, wide-band connection to the network is established everywhere in a room. As the most fundamental problem of this system, we examine the physical connection property between the standing waves produced in the tile and a coupler put near the surface. The results in the simulations and the experiments show stable UWB communication based on OFDM is achieved with the proposed system.
