Abstract. According to the recently published IEEE standard 802.15.3d (2017), THz links operating at 300 GHz are viable to achieve more than 100 Gbit s−1 of data rate. This feature can support a transition of the future backhaul connectivity from the underground fibre connection to the wireless, where fibre links are not available or too costly to install. The EU-Japan Horizon 2020 project “ThoR” is working towards the demonstration of such links. A detailed investigation on the influence of weather conditions will help to derive planning guidelines of 300 GHz backhaul links for forthcoming applications. This paper focuses on the dependency of the THz link on the general weather by using ray-tracing simulation. Simulation is conducted combining ITU-R propagation models for atmospheric attenuation (water vapour and oxygen content of air, droplets of rains, liquid content of clouds or fog), a wind-depending swaying model for the antenna poles, and historical measured climate data for the deployment scenarios considered in the ThoR project. As a result, this research will show the feasibility of THz link in outdoor applications under general weather conditions, defines weather-dependent outage probabilities, and allows us to derive planning guidelines of THz links at a frequency of 300 GHz.

“…Parts of the approaches described in chapter 3 have been applied to SiMoNe [9] and the channel calculations have been applied to both system and link level simulations [18]. Figure 7 shows the signal vector constellations diagram using SiMoNe's link level simulator for a QPSK modulation and an assumed Signal-to-noise-ratio (SNR) of 20 dB applied to the scenario depicted in Figure 2.…”

“…For channel and propagation prediction, ray tracing is used as the basic tool [7] in two implementations: An in-house developed ray tracer available in TUBS' Simulator for Mobile Networks (SiMoNe) [9] and a commercial ray tracer available at CIT [10]. These tools have been enhanced by the models and features described in the following three sections.…”

The need for high data rates of several Gbit/s in 5G and beyond wireless networks will require capacities of 100 Gbit/s in the backhaul and fronthaul links. 300 GHz wireless links are promising candidates to provide these links. The paper describes the ongoing activities in the EU-Japan project ThoR towards suitable propagation and channel models applicable for the simulation and planning of such links. The corresponding modelling activities are based on ray tracing models, which are enhanced by taking into account atmospheric propagation effects, measured characteristic of building materials and the effect of wind to the poles, where the antennas are mounted. First results applied to realistic simulation scenarios are presented.

“…The system-level simulation is accomplished with the help of an in-house developed simulator for mobile networks (Si-MoNe) [6]. It has been originally developed for simulating realistic cellular networks with hundreds of radio cells and thousands of mobile subscribers.…”

In the future, the base stations are expected to be deployed with higher density. To save cost and man forces, wireless links operating at 300 GHz can replace conventional cable-based backhaul connections. One of the goal of Horizon 2020 EU-Japan project ThoR is to design automatic planning tools for 300 GHz wireless backhaul network. To accomplish this task, a novel planning tool has been developed to plan backhaul links with the usage of a ring topology. To evaluate the proposed tool's functionality, system-level simulations are conducted with an in-house developed mobile network simulator. In this paper, the algorithm of the new planning tool for 300 GHz wireless backhaul network is introduced and the SINR characteristics of the planned THz links are evaluated using 3D ray optical path loss predictions. For that, a realistic scenario of an ultra-dense cellular network in Hanover, Germany, is used with the diverse tropospheric climate conditions.
