Providing a 60 GHz millimeter-wave communication link for autonomous driving support demonstration experiments in Shiojiri City

Fujikura participated in an autonomous driving support demonstration in Shiojiri City, Nagano Prefecture in December 2021. In this demonstration, a 60 GHz millimeter-wave communication link was provided for remote sensor information monitoring using smart poles^*1. This communication link is used in the driving support of autonomous vehicles.
Using Fujikura’s 60 GHz millimeter-wave communication link, remote monitoring of sensor information from a smart pole could be performed without any delay, thus confirming the practicality of 60 GHz millimeter-wave communication. It was also confirmed that the communication quality was stable and that the equipment was easy to install using beamforming technology. Overall, Fujikura’s 60 GHz millimeter-wave wireless communications module combines low-delay, large-capacity communication with millimeter waves, while also offering stable communication with low interference thanks to sharp beam characteristics with directivity, as well as ease of installation.

Explanation of terms

*1 Smart pole:
This is a post that combines various communication devices, sensors, displays, and functions such as those for external connection. It is currently implemented for practical use. Figure 1 shows a schematic diagram of a smart pole.
*2 ITS Connect:
ITS Connect is a representative vehicle-to-everything (V2X) service. It is a system that supports safe and secure driving by notifying drivers with the information obtained via wireless communication between the infrastructure equipment installed on the roadside, and vehicles (road-to-vehicle communication, V2I). This system also allows direct communication between vehicles (vehicle-to-vehicle communication, V2V) at intersections, including cases with poor visibility.
