Case Study

Seamless High-Speed Handover in Circuit Racing with Private 5G


Background

In a demonstration conducted on January 30–31, 2025 at a racing circuit, Hytec Inter partnered with IIJ Group, Japan Circuit, MoSRA, M-TEC, and others to deploy Hytec’s portable private 5G network over sections of the track. The aim was to verify real-time transmission of onboard video and telemetry from a test vehicle traveling at speeds above 150 km/h.

Objectives

  • To evaluate low-latency transmission of onboard video and telemetry at high speeds (150–200 km/h)
  • To demonstrate mobility support through cell-to-cell handover during vehicle operation
  • To verify that a portable, closed-loop Hytec’s private 5G network can function independently of public infrastructure

System Overview

  • Used Hytec Inter’s O‑RAN compliant portable private 5G platform, configured for Intra‑gNB DU handover at speeds over 150 km/h—the first instance in Japan
  • The platform was rack-mounted for swift deployment and supported various outdoor sector antennas optimised for circuit topography
  • Equipped the test “Civic Type R” vehicle with onboard video/telemetry systems to feed data over Hytec’s private 5G network

Key Results

Real-Time Data at High Speed

The system successfully transmitted high-resolution video and telemetry from the car traveling at speeds up to 200 km/h, with low latency and stable connectivity, proving the platform’s ability to support real-time, high-speed mobile applications.

Verified High-Speed Cell Handover

The demonstration achieved Intra-gNB DU handover—that is, transitioning communication between base stations during vehicle movement—within a Sub-6GHz private 5G setup. This marked the first successful test of its kind in Japan.

Portable, Self-Contained 5G Infrastructure

The network was fully self-contained, deployable in a compact rack-mounted system. This makes it ideal for temporary or remote deployment scenarios, such as live events, motorsport testing, or field operations with no pre-existing network.

Conclusion

This demonstration proves that Hytec’s private 5G can support high-speed, mobile use cases such as motorsports telemetry and vehicle R&D. With low latency, verified handover performance, and a portable architecture, the solution offers new potential for real-time mobility applications where public networks fall short.
