Pilots use of LTE in European train control
Nokia has tested voice and data calls over the world’s first 4.9G/LTE private wireless network. It plans to use the technology to support European Train Control System (ETCS) Level 2 signalling. By successfully proving it works for it has completed phase 1 of the National Capital Region Transport Corporation’s (NCRTC’s) Regional Rapid Transit System.
The pilot project covers an 82 km, 25 station rail route between Delhi and Meerut in India and the system will be implemented in four stages. Nokia is partnering with Alstom to install the private network which is due to be completed by 2025. “The initiative will significantly transform the region,” said Thameem Kamaldeen, Signalling Director at Alstom India.
The advantage offered by the 4.9G/LTE combination is that it can support advanced broadband applications. This makes it the medium of choice to support voice signalling which is a critical technique in this system. Nokia says is the first time anyone in the world has used an LTE network in conjunction with ETCS Level 2 signalling to provide a high-speed, ultra-dependale commuter service.
The system lets trains report their precise location to the millisecond, which helps them alert commuters to their exact location and cuts the waiting time on station platforms and concourses, making journeys less stressful by avoiding congestion and eliminating the uncertainty.
As part of the agreement, Nokia will provide Nokia Evolved Packet Core (EPC), Compact Mobile Unit (CMU), NetAct, Network Services Platform (NSP), installation and commissioning services and integration services. Nokia will also run an Operation Control Center and Back-up Control Center.
“We have worked closely with major railway operators to bring the benefits of private LTE connectivity and pave the way for the adoption and deployment of Future Railway Mobile Communication System,” said Kamal Ballout, Nokia’s Head of Enterprise Solutions for China, India, Middle East and Africa.
