According to Statista, connected car penetration will be around 18% in 2018 and exceed 44% by 2022.

However, for some of the more advanced connected car applications such as self-drive to be possible, or even for in-car entertainment to deliver the user experience consumers have come to expect in their homes, connectivity needs to be better than current mobile services can achieve. 5G promises the requisite speed and latency capabilities but needs to prove it is capable of delivering on the move, at speed. To this end, KDDI and Samsung Electronics completed a comprehensive set of 5G tests that demonstrate the viability and performance of 5G millimeter wave mobility solutions at speeds over an impressive 190 km per hour.

The demonstration took place at 'Everland SPEEDWAY' in Korea, involved a battery of individual tests to examine the performance of Samsung’s end-to- end 5G mmWave technology. Specifically, as a vehicle accelerated from 0 to 205 km per hour on the race track between multiple 5G base stations, the test measured and evaluated a variety of metrics, including handover interruption time, uplink
and downlink throughput stability, and latency stability (or ‘jitter’).

In addition, KDDI and Samsung also demonstrated a successful handover scenario, with Samsung's 5G device attaching to the 5G base station as it approached the service area, where it was successfully handed over to the target cell at a speed of 192 km per hour (GPS speed).

These tests represent the next step up in speed, following on from a previous successful demonstration of 5G handover capability in an urban city environment at speeds of up to 60 km/h on public roads.

Woojune Kim, Senior Vice President and Head of Next Generation Strategy in Networks Business at Samsung Electronics, said, “It is becoming increasingly important that we accelerate our focus on 5G’s ability to meet a growing number of performance metrics. Until now, peak bandwidth has been the common refrain, and certainly a big component of the future of 5G. However, the test we conducted with KDDI will help us build a more diverse portfolio of future 5G use cases.”

The trial successfully showcased stable performance under high-speed mobility conditions which will dramatically increase the service experience of users in vehicles. We will continue our joint efforts with Samsung to test next generation technology to unprecedented levels and discover new service cases.
