Japan Cabinet to consider plan to put 5G base stations on traffic lights

The idea was included in the government’s IT strategy as a route to accelerating the roll-out and reducing the cost of 5G deployment.

The plan covers around 200,000 traffic signals which are controlled by  local governments.

Local authorities are being encouraged to give permission for the installations by the prospect of using the base stations for emergency and C2V communications for  autonomous driving.


Testing of 5G base stations installations on traffic lights is to begin next year and run through 2021.

A nationwide 5G network, requiring several hundred thousand base stations,  is planned for 2023.

The shorter range of 5G signals compared to 4G signals requires telcos to find many new base station sites.
