Private 5G on test track speeds up development cycle for at automotive

At an automotive proving ground where every test produces terabytes of data, the fastest vehicle is not the only measure of speed. The automotive enterprise needed to move autonomous vehicle test data from a track more than 10 km long into a global development workflow without waiting for cars to return and connect by cable.
NTT DATA deployed a managed private 5G environment integrated with AWS and dedicated access lines. The solution enables real-time data sharing, allowing software improvements to be made on the same day and significantly shortening the development cycle.

From Every Lap to Faster Engineering Decisions

Each lap can now feed the next engineering decision. Real-time sharing replaces the previous cable-dependent handoff, allowing development partners to begin analysis sooner and software teams to act within the same day.

From post-drive uploads to a live global development loop.
目的
the automotive enterprise set out to create continuous high-speed wireless coverage across a proving ground extending more than 10 km, where each autonomous vehicle test generates terabytes of data. The network needed to move that data quickly into an AWS-connected environment, make it available to development partners worldwide and remove the delay created by cable-based uploads after each drive. Just as important, The automotive enterprise wanted the network operated as a managed service so its teams could keep their attention on vehicle development rather than day-to-day network operations.
機会
With real-time test data available beyond the track, the development process can move from sequential handoffs to faster collaboration between test teams, software engineers and global partners. The automotive enterprise plans to extend private 5G to other test tracks and is also considering its use in production factories. These next steps remain future plans. Their scope, timing and results have not yet been confirmed.
A proving ground built for motion, a data flow built around waiting

The automotive enterprise’s autonomous vehicle program needed connectivity that could span the track, carry very large test datasets, connect securely to cloud resources and operate without drawing development teams into day-to-day network management.

解決策
One managed pathway from vehicle to cloud

NTT DATA combined private 5G, cloud connectivity and managed operations in a one-stop service covering network design, construction and operation.

チェックアイコン
Private 5G across the proving ground

A high-quality private 5G system was designed and built to provide wide-area wireless connectivity across the test environment.

チェックアイコン
High-speed vehicle data upload

The solution delivered upload speeds exceeding 400 Mbps and included private 5G CPE to connect test vehicles to the network.

チェックアイコン
Secure AWS integration

AWS and dedicated access lines were securely connected to create an end-to-end route for test data and support global development collaboration.

チェックアイコン
Managed network operations

NTT DATA took responsibility for network design, construction and operation through its Managed Private 5G service.

影響
Same-day learning from every test run

Before the deployment, vehicles had to be connected to data servers by cable after each drive. Development partners could not begin analysis until the next day. With real-time data sharing over private 5G, software improvements can now be made on the same day, significantly shortening The automotive enterprise’s development cycle.

Four business units, one technology roadmap after the merger
After an acquisition, a retail group ran four business units on four technology stacks. NTT DATA mapped processes, applications, ERP, CRM and infrastructure across all of them and designed a low-risk transition roadmap. The group now works from a prioritized portfolio of initiatives, with synergies identified for each unit.
