Nokia, KDDI successfully trial 4G LTE connected vehicle applications in Japan
NEW DELHI: 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.
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.”

NEW DELHI: The Union Cabinet chaired by the Prime Minister Narendra Modi has approved a Universal Service Obligation Fund (USOF) project for upgrading 2G mobile services to 4G at security sites in Left Wing Extremism (LWE) areas
The Project envisages upgrading2,343 left Wing Extremism Phase-I sites from 2G to 4G mobile services at an estimated cost of Rs.1,884.59 crore (Excluding taxes and levies). This includes O&M for five years. However, BSNL will maintain the sites for another five years at its own cost. The work will be awarded to BSNL because these sites belong to BSNL.
The Cabinet also approved funding of operations and maintenance cost of LWE Phase-I 2G sites by BSNL for an extended period beyond the contractual period of five years at an estimated cost of Rs.541.80 crore. The extension will be up to 12 months from the date of approval by the Cabinet or commissioning of 4G sites, whichever is earlier.
Government chose BSNL for a prestigious project to indigenous 4G telecom equipment so as to achieve self-reliance in the telecom gear segment to fulfil domestic market needs apart from exporting to other markets. This 4G equipment will be deployed in this project also.
The upgradation will enable better internet and data services in these LSW areas. It meets the requirements of Ministry of Home Affairs and the state governments. It shall also fulfil the communication needs of the security personnel deployed in these areas. The proposal is in line with the goal of providing mobile connectivity in rural areas. In addition, delivery of various e-governance services, banking services, tele-medicine; tele-education etc. through mobile broadband shall be possible in these areas.
NEW DELHI: Reliance Jio Infocomm Ltd. (Jio), India’s leading 4G and mobile broadband digital service provider, is constructing the largest international submarine cable system centered on India. Jio, in conjunction with several key global partners and world-class submarine cable supplier SubCom, is currently deploying two next generation cables to support the extraordinary growth in data demand across the region.
The India-Asia-Xpress (IAX) system connects India eastbound to Singapore and beyond, while the India-Europe-Xpress (IEX) system connects India westbound to the Middle East and Europe. The systems will seamlessly interconnect as well as connect to the world’s top interexchange points and content hubs for extension of service globally. IAX and IEX will enhance the ability for consumer and enterprise users to access content and cloud services in and out of India.
For the first time in the history of fiber optic submarine telecommunications, these systems place India at the center of the international network map, recognizing India’s increased importance, staggering growth, and the quantum shift in data use since the launch of Jio services in 2016.
These high capacity and high-speed systems will provide more than 200Tbps of capacity spanning over 16,000 kilometers. Employing open system technology and the latest wavelength switched RoADM/branching units ensures rapid upgrade deployment and the ultimate flexibility to add/drop waves across multiple locations.
“Jio is at the forefront of India’s explosive growth in digital services and data consumption. To meet the demands of Streaming Video, Remote Workforce, 5G, IoT, and beyond, Jio is taking a leadership role in the construction of the first of its kind, India-centric IAX and IEX subsea systems,” said Mathew Oommen, President, Reliance Jio.
“Implementing these critical initiatives in the shadow of a global pandemic is a challenge, but the ongoing pandemic has only accelerated the digital transformation and the necessity of high-performance global connectivity for the delivery of a richer experience to enterprises and consumers,” he added.
The IAX system connects India, the world’s fastest growing economy, to Asia Pacific markets with express connectivity from Mumbai and Chennai to Thailand, Malaysia, and Singapore. The IEX system extends India’s connectivity to Italy, landing in Savona, and additional landings in the Middle East and North Africa.
Apart from the seamless connection of the IAX and IEX sub-sea systems, the two systems are also connected to the Reliance Jio Global Fiber Network beyond Asia Pacific and Europe, connecting to both the east and west coast of the USA. IAX is expected to be ready for service mid-2023, while IEX will be ready for service in early 2024.
