Telecom Infrastructure Project






SIRADEL is a member of the TIP since 2016 and has been involved in the first Terragraph deployment in San Jose, California. Ever since, SIRADEL has been actively working inside the TIP eco system. Using its experience in channel sounder measurement data collection and comparison to simulations, SIRADEL strongly contributes to the mmWave Networks Project Group, which aims at collectively solving the new challenges faced by the telecom infrastructures at 60 GHz.

An ambitious measurement campaign was organized by the TIP mmWave Project Group to investigate the mmWave channel properties in various kinds of environment based on a Facebook innovative sounder equipment. SIRADEL has participated in the outdoor scenarios study, in particular for campus, canyon and residential situations. SIRADEL demonstrated the ray-tracing capability to complement the measurement-based analysis and emulate the radio multi-paths, when associated to accurate LiDAR data.

Find below an extract of the “Analysis of 60-GHz In-street Backhaul Channel Measurements and LiDAR Ray-based Simulationspaper written in collaboration with Deutsche Telekom presenting our contribution to the mmW Channel Modeling Group:

“The large gains provided by millimeter-wave (mmWave) frequencies in terms of available bandwidth have made them a popular choice to be included in different standards like the 5G-NR and IEEE 802.11ay. Although mmWave frequencies offer an opportunity for large capacities, they face many challenges related to the propagation channel such as strong blockage or attenuation losses. In this paper, 60 GHz in-street backhaul propagation channel is measured and evaluated along with ray-based simulations in two different scenarios; urban canyoning and residential. The channel sounder allows for bi-directional path-loss measurements with highly-directive beamforming at both sides. And the simulator takes benefit from highly accurate LiDAR point cloud data in order to identify the obstacles and compute losses along the direct and indirect paths. Both the measurements and simulations show strong channel sparsity when antennas are located at 3 meters above the ground, caused by the many instreet obstacles.”
