Agile Optical Network and Microwave Packet Radio for Rail

A WDM (Wavelength Division Multiplexing) optical communication network opens the gates to increased flexibility to introduce new bandwidth hungry applications and services, while reducing cost of operations and still maintaining safety and security.

Transportation operators recognize the benefits of an additional WDM layer, and equally appreciate the benefits that WDM provides during the transition from their existing SDH legacy optical infrastructure towards the final converged IP/MPLS infrastructure. Nokia WDM optical networks support a temporary hybrid communications platform allowing the various subsystems to migrate at their own speed. There is no need to rip and replace existing legacy networks or applications. This enables a smooth migration path to the future.

Microwave Packet Radio (MPR) is also an optimized solution to provide a wireless backhauling networking function to build high-bandwidth, mission-critical transmission networks.

High bandwidth services run on the same network and systems

  • Greater network capacity and performance able to support high-bandwidth applications, such as driverless trains and networked CCTV
  • Safety systems, including emergency contact points, mobile radio and alarm systems, work together for greater trackside and onboard security
  • Large amounts of data -- for example, station and train CCTV feeds.

How can Nokia help?

  • Nokia drives the evolution and convergence of today’s WANs with new optical and microwave standards. The company is an expert in mission-critical communications projects, providing services to design, install, and maintain the solution. With our optics, microwave, IP/MPLS and LTE portfolio, rail-industry experience in mission-critical IP and ultra-broadband Infrastructure, Nokia has all the elements that rail operators need to simplify their network transformation and reduce OPEX while increasing competitiveness and achieving greater control over their business.
