Simulation and Automatic Planning of NLoS Backhaul Links at 300 GHz using Ring Topology

In 5G and beyond cell deployment is expected to be ultra-dense to provide the possibility of high data rate transmission to the users. Providing fibre backhaul links to all the new cell sites is costly, time-consuming, and not available everywhere. THz links operating at 300 GHz can be a fair compromise to replace fibre backhaul links enabling the provision of more than 100 Gbps data rate based on IEEE Std 802.15.3d. In a recent hardware demonstration within the Horizon 2020 EU-Japan project ThoR, the potential of high data transmission via a wireless link has been verified while completing the world's first bi-directional wireless data transmission over 160 m at 300 GHz with real data. In the same project, several algorithms for the automatic planning of 300 GHz backhaul links have been developed taking into account various network topologies. In this paper, a novel algorithm taking into account NLoS links in a ring topology will be presented. The performance of this algorithm has been analyzed and compared with the previously introduced algorithm using an in-house developed simulation tool.
