Espoo, Finland - Nokia and KDDI have successfully
demonstrated the use of LTE in Japan to deliver cost-efficient,
low-latency connectivity for vehicles. The trials are the first in
the world to use LTE broadcast, implementing the evolved Multimedia
Broadcast Multicast Service standard in two connected car
applications, and 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:
- Vehicle-to-network-to-vehicle (V2N2V) - in which cars
maintained constant contact with the MEC system, sending real-time
location, direction and speed data to roadside sensors. In an
emergency situation, the driver can alert the application, with
information distributed to other vehicles using eMBMS.
- Network Real-Time Kinematic (network RTK) -trial of LTE to
enhance fully automated in-vehicle navigation. It showed how eMBMS
could more cost-efficiently use existing geo-location systems to
communicate to many vehicles in real-time and ensure accurate
navigation.
The trials were conducted by Nokia and KDDI at a rural location
on the Japanese island of Hokkaido.
Mr. Munefumi Tsurusawa, Ph.D, General Manager, Connected
Vehicle Technology Department, Technical Planning Division at KDDI
Corporation, said: "We are pleased to work with Nokia to
demonstrate our leadership in the delivery of mobile networks for
IoT and connected car communications. This is an important trial
showing how the automotive industry can leverage cellular
technology to enhance safety of connect vehicles on the roads."
Uwe Puetzschler, head of Car2X at Nokia, said: "Nokia has
a comprehensive solution package for V2X based on its MEC platform
and eMBMS hotspot solution aiming to cost-effectively accelerate
the adoption of vehicle-to-everything communication. While manual
intervention was used in the proof-of-concept trials, a clear
evolution path to 5G will enable operators such as KDDI to support
the widespread adoption of automated vehicles."
