Nokia, KDDI flag successful trial of 4G LTE connected vehicle apps in Japan

Nokia and KDDI have announced the successful demonstration of the use of LTE in Japan to deliver cost-efficient, low-latency connectivity for vehicles.

1Nokia billed the trials as the first in the world to use LTE broadcast. having implemented its evolved Multimedia Broadcast Multicast Service standard in two connected car applications, demonstrating the potential of cellular technology to enable fully automated driving in the future. 

Vehicle-to-Everything (V2X) technology is designed to connect vehicles to each other, to communications network infrastructure, and to roadside sensors, including connectivity to traffic lights, radar and other functions.

For the proof-of-concept trials in Japan, Nokia and KDDI focused on vehicle to network usecase and used non-integrated systems in cars interacting with sensors via the Nokia Multi-access Edge Computing (MEC) platform, which enables significantly reduced network latency.

 

The Nokia evolved Multimedia Broadcast Multicast service (eMBMS) hotspot solution, allows data to be sent once to many users simultaneously. Used in the trial it allowed real-time information to be shared with multiple vehicles to cost-effectively enable awareness and road safety. The companies compared the efficiency of using LTE broadcast to the one-to-one communication enabled by LTE unicast, in two connected car applications:
