Rail communications have not been immune from the information technology revolution, but any new rail solutions need to be rock-solid since safety is on the line. Rail communications failure is just not an option.
Moving from separate network services to a converged IP/MPLS multi-service network is helping railway operations make a step-change in flexibility and efficiency while reducing total cost of ownership.
IP convergence--and IP/MPLS in particular—bring safety-related train control communications under a single unified architecture while delivering new railway communications flexibility.
One railway operations pioneer, Portugal’s REFER Telecom (the telecommunications subsidiary of Portuguese railway infrastructure manager, REFER E.P.E), has been using a fixed IP communications network since 2004. Since 2008 it has been running on IP/MPLS technology provided by Alcatel-Lucent.

In the face of global threats and terrorist acts, collaboration and sharing best practices can help railway operators optimize their security capabilities. In addition, improving rail security by upgrading communications capabilities allows railroad providers a single, high-capacity network that can support multiple applications. In fact, such new applications improve the transportation experience for customers and enable railroads to keep existing riders and attract new ones.
A recent Alcatel-Lucent article in its TrackTalk e-zine for railways communications enttitled, “Partnerships are the key to a secure railway,” looked at how the rail industry is responding to the security challenges of the 21st century with solutions such as IP MPLS broadband networks and CCTV systems.

Ever-increasing energy consumption, skyrocketing operating costs and pressure from regulatory bodies to help create a greener world have forced power utilities to reassess their delivery management methods.
The need for change – along with the recent influx of innovative network technologies – has led many utilities and distribution and system operators (TDSOs) to embrace the smart grid, a concept aimed at leveraging the power of next-generation networks to improve the efficiency and reliability of energy delivery and usage. The visibility and control provided by the smart grid enables utilities to match supply and demand, optimize delivery, cut operating costs and reduce carbon emissions.
In addition, a smart grid opens up a two-way communication system between utilities and customers, thus creating additional upsell opportunities and the ability for consumers to take a hands-on approach to energy conservation. Smart grid customers have access to their own webpage that details their energy consumption and the associated costs.
Deploying a smart energy grid is vital for utilities to thrive in the current environment, but it doesn't come without complications. TDSOs need to chose the appropriate technologies, understand their network requirements and make major decisions like if they should build their own communications infrastructure or lease it from a service provider.
Many of these questions can be answered by Alcatel-Lucent, whose Integrated Communications for Power Utilities solution is a proven way to take utilities into the 21st century of energy delivery and efficiency.
With its experience designing and deploying IP and LTE broadband wireless access networks, Alcatel-Lucent has a unique perspective on what is needed to get a smart grid initiative up and running.
