Polarization Planning for Wireless Networks

International audiencePolarization diversity enables frequency reuse in a telecommunication network. The most widely considered solution is to use two orthogonal polarizations on the same link, which enables to double the available bandwidth. In this paper, we study the possibility to connect the nodes of a ring topology network with one single channel for all the links, with the condition that the polarization of any link is orthogonal to the polarization of the two adjacent links. The solution proposed in this paper can improve spectrum efficiency by up to 50% in comparison with the widespread polarization multiplexing solution. Furthermore, it has implications on network topology and channel allocation
