Mission-Critical Transmission Networks for Railways

Nokia offers highly available mission-critical communications infrastructures for the rail industry.

Multi-services communication networks able to support both mission-critical applications and new passenger services require state of the art transmission products based on Microwave, Optical and IP technologies.

The Microwave Packet Radio (MPR) range of products are optimised to provide point-to-point or point-to-multipoint wireless IP transmissions to backhaul all equipment placed along the tracks, such as GSM-R base stations. This is a cost-effective solution, especially in hilly relief. Our 9500 MPR product is natively integrated with our IP/MPLS routers, reducing the installation, management and maintenance costs.

The WDM (Wavelength Division Multiplexing) optical switches open the possibility to introduce new bandwidth-hungry applications to the wired network or to resell bandwidth capacity to generate new revenues. They can help railways operators smoothly migrate their existing SDH legacy optical infrastructure to a final converged IP/MPLS and Optical network.

The IP/MPLS switches and routers is a comprehensive suite of products designed to build multi-services and mission-critical communication networks providing resiliency, security, traffic segregation and high quality of services. They allow a smooth migration to IP without the need to remove or replace legacy applications or services. They are managed by our unified management platform; 5620 SAM such as the MPR and PSS products.
