The first step to the future communication that makes full use of light.Possibility of communication spread by successful testing experiments of "tracking optical radio communication technology"

On March 18, 2021, SoftBank Co., Ltd. and Nikon, Co., Ltd. held a press briefing on new technologies for Hikari Radio Communications.We gave an overview of the joint demonstration of "Tracking Hikari Radio Communication Technology", which succeeded in demonstration for the first time in the world, and a demonstration of new technology.

"Light" was focused on new communication technology

The current wireless communication is provided using radio waves in the frequency band assigned to each company.However, while radio bands are limited, more and more large -capacity communication is required in the future.

"In anticipation of the 6G era, R & D of communication technology using submirial wave and infrared light is progressing in anticipation of the 6G era, but more sustainable and higher value communication.As a result of exploring new areas to provide, we focused on light. It does not mean that light is replaced by radio waves, but a future that can respond to various needs while complementing each other complementing each other."Showed me the idea.

In addition, he emphasizes the possibility that the Hikari Radio Communications has hidden, saying, "In the world of light radio communication, the common sense that has been performed in radio communication has been overturned, and it will be a completely new world."Since the secure is low in latency (delay) and large -capacity communication can be expected, it can be used for various purposes that require stable communication, such as autonomous driving, drones, and delivery robots.There is also the possibility that it can be used underwater and underground.

光無線通信の特徴

Radio waves interfere with other frequency bands, causing noise, but the nature of light is different from radio waves, so they can coexist without interfering with each other.However, another nature of "straightness" light has become a barrier that greatly expands the range of use.
