Trial used vehicle-to-network-to-vehicle connectivity and network real-time kinematic for location awareness and accurate navigation
Nokia and Japanese telecommunications operator KDDI have demonstrated the use of LTE to deliver connectivity for vehicles.
The trials used LTE broadcast, implementing evolved multimedia broadcast multicast service standard in two connected car applications in Japan, demonstrating the potential of cellular technology to enable fully automated driving in the future, said Nokia.
For the proof-of-concept trials, the companies focused on vehicle to network, and used non-integrated systems in cars interacting with sensors via Nokia’s multi-access edge computing (MEC) platform.
“We are pleased to work with Nokia to demonstrate our leadership in the delivery of mobile networks for IoT and connected car communications,” said Munefumi Tsurusawa, general manager, connected vehicle technology department, technical planning division at KDDI Corporation.
“This is an important trial showing how the automotive industry can leverage cellular technology to enhance safety of connect vehicles on the roads.”
Nokia’s 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 which were:
“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,” added Uwe Puetzschler, head of Car2X at Nokia.
“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.”
The trials were conducted by Nokia and KDDI at a rural location on the Japanese island of Hokkaido.
