A Nokia and ENGIE Solutions consortium is to implement a private LTE wireless network for the new automated lines 15, 16 and 17 of the Grand Paris Express metro on behalf of client, the Société du Grand Paris (SGP).

The project will cover over 200km of new lines, 68 new metro stations and all of the metro trains running on the Paris metro. The scheme will provide critical, high-speed wireless connectivity services, designed to meet all future Grand Paris Express operational and maintenance requirements, as well as its transportation network emergency and security needs.

The decision to deploy a private LTE wireless network is part of a new approach by the Société du Grand Paris, as it replaces conventional technologies traditionally used in metro transport with a broadband technology solution.

The private mobile LTE radio solution will be used for operational communications and indoor/outdoor connectivity across all Grand Paris Express stations, lines and depots. These include voice, data (file transfer and multimedia support) and video services (transmission, on-board video surveillance).

The role of ENGIE Solutions is to provide its expertise in design and construction of rail transport infrastructure (tram, metro, conventional or high-speed rail lines). ENGIE Solutions will be responsible for steering the project value chain including overseeing study, purchasing, construction, and testing until global commissioning of the transport service.

ENGIE Solutions will rely on a team specialising in strategic support for the management of complex railway projects and the integration of systems, including requirements, interfaces, risks, safety and performance.

Matthieu Bourguignon, vice president for Europe, Nokia Enterprise, said, “Creation of the new Grand Paris metro is an ambitious project and we are delighted to collaborate with ENGIE Solutions as part of this project. Our selection by the Société du Grand Paris confirms Nokia's place as a telecom leader in the transport marketplace and in particular on critical network solutions such as GSM-R, 4.9G/LTE, 5G, IP/MPLS, cybersecurity and IoT analytics.”

Jean-Luc Figuereo, director of the transport infrastructure market at ENGIE Solutions, said, "This project is not just a transport project, it is also a big digital transformation project. We are thus helping to create the cities, neighbourhoods and infrastructure of tomorrow that are more resilient and connected to their ecosystems.”

The Grand Paris Express is an automated transit network designed to provide a new metro system for the Île-de-France region. Grand Paris Express consists of a ring route around Paris (line 15) and lines connecting developing neighbourhoods (lines 16, 17 and 18). It includes 68 new stations and 200km of additional tracks.

The Grand Paris Express project also involves the extension of existing metro lines. Its four new lines circle the capital and provide connections with Paris’ three airports, business districts and research clusters. It will service 165,000 companies and transport two million commuters on a daily basis.

Nokia said it now has over 130 large enterprise customers using 4.9G/LTE and 5G private wireless networks around the world.
