NTT trials low-latency private 5G video transmission in motorsports

NTT Com, Alps Alpine and Sojitz Tech Innovation have established a private 5G experimental environment at Mobility Resort Motegi to enable high-quality wireless communication across the entire circuit course. In this trial, the companies will verify whether high-definition, low-latency video can be transmitted from a fast-moving vehicles within the established private 5G environment, aiming to enhance customer experience at the circuit.

The operator has been actively using ICT in the motorsports sector. Currently, wireless communication at circuits is used for various purposes, including the transmission of sensor data from vehicles and equipment, the use of transceivers, cashless payments at shops, and video transmission from onboard cameras. In recent years, there has been growing demand for real-time onboard footage of race cars to enhance the immersive experience of race spectators.

To ensure reliable wireless communication across the circuit, three key initiatives have been implemented. A private 5G network, operating on a separate frequency from carrier 5G, has been deployed to maintain stable connectivity during high-traffic events, preventing network congestion from affecting circuit operations. Additionally, private 5G base stations have been strategically installed and optimised to cover areas with weak signals caused by obstacles like buildings and tunnels.

Adjustments to handover parameters have also been made to support seamless communication for high-speed movement. Finally, the demonstration explores using a millimetre-wave wireless system to connect base stations to the 5G core, providing a solution for locations where physical cable connections are impractical.

Based on the results of this trial, the companies will continue to develop private 5G systems for high-definition, low-latency onboard video transmission and stable payment communication at the venue to enhance race-goers’ experience. Further, they will continue practical testing of millimetre-wave wireless systems for private 5G networks. Additionally, the feasibility of using real-time video data from high-speed vehicles and drones for applications such as surveillance, security, and inspections will be explored.
