Optical Wireless Communication System

State-of-the-Art Communication System Without Radio Waves:
LED Backhaul®

System Features

POINT1

Stable Communication

Since it does not use radio waves, stable communication is possible without interference.

POINT2

High Speed and Low Latency

As it is not radio equipment that uses radio waves, obtaining a license is not required for operation. It can be used freely anywhere in the country.

POINT3

No License Required

As it is not radio equipment that uses radio waves, obtaining a license is not required for operation. It can be used freely anywhere in the country.

POINT4

Product Development Designed for Outdoor Use

Waterproofing allows for outdoor use. Communication remains uninterrupted even in the rain.

POINT5

Easy Installation

It can be easily installed without specialized skills. It is ideal for use as a transmission path for surveillance camera footage at event venues where repeated setup and removal are required.

Diverse Applications of LED Backhaul®

Scenario01

Networking Private Areas

By combining Wi-Fi 6 and LED Backhaul, wireless networks can be constructed using entirely unlicensed bands.

Enables private area networking in combination with Local 5G or Wi-Fi 6.

Scenario02

Remote Operation of Equipment

Using LED optical wireless communication ensures stable communication even in high-noise environments such as factories and warehouses.

Used as a 5G backhaul for the remote operation of heavy construction machinery equipped with 5G terminals.

Capable of transmitting camera footage required for remote operation without latency!

Scenario03

Backup Lines for Events

LED optical communication provides peace of mind even if wireless devices become unusable due to unexpected radio interference or cable damage during an event!

As a video transmission system for large displays used in short-term events lasting only three days.

As a communication system for constructing network environments for events.

Scenario04

As an Alternative to Wi-Fi Access Points and Wired LAN

Ideal for extending networks between buildings separated by public roads or rivers where wired LAN is difficult to install!

Connecting a Wi-Fi access point allows for the creation of a Wi-Fi environment in a distant building.

Case Studies Applying Optical Communication

Applying LED Communication Technology to Inter-vehicle Communication Systems

Participated in the National Project: "Truck Platooning"

In the "Demonstration for Social Implementation of Truck Platooning" project promoted by METI and MLIT, an experiment for unmanned platooning of following trucks equipped with SANGIKYO's LED communication technology was successful. We are contributing to technical validation for social implementation.

What is the "Demonstration for Social Implementation of Truck Platooning" Project?

This is an R&D and demonstration project started in 2016 aiming at realizing unmanned platooning for following trucks to solve challenges in the logistics industry, such as serious driver shortage and fuel efficiency improvement. Toyota Tsusho Corporation was commissioned for this project by the Ministry of Economy, Trade and Industry (METI) and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), and SANGIKYO has been in charge of inter-vehicle optical communication devices since 2017. By continuously improving upon the optical wireless communication technology of our product, LED Backhaul®, we provide it as an inter-vehicle communication system.

Case Study

Demonstration Experiment Conducted on a Section of the Shin-Tomei Expressway

Three large trucks travelled at 80km/h while maintaining a 9-meter following distance. Only the lead vehicle had a driver in the driver's seat, while the following vehicles were driverless in the driver's seat and had safety personnel seated in the front passenger seat.
