Automatic Planning of 300-GHz-Band Wireless Backhaul Link Deployment in Metropolitan Area

This paper proposes an algorithm for automatic planning of 300-GHz-band wireless backhaul link deployment. The algorithm consists of two steps; Selecting the pair of adjacent cells that can get a line of sight, and Deployment of base stations. We succeeded in the automatic planning of 300-GHz-band backhaul link in Shinjuku, Japan by using this algorithm. We conducted radio wave propagation simulation of the wireless backhaul links, and showed that SNR of 99.5 % of the wireless backhaul links deployed by using this algorithm exceeds the standard demand SNR for 100-Gbit/s data transmission even when the rain rate is 100 mm/hr.
