Keeps smart cities on the move

Communication solutions for metro lines, railways, transportation companies

Convenient and safe public transportation is used by billions of people every day. Communication and collaboration is not just an important, but a vital service that transportation companies need to fulfill the high expectations of their customers.

Passengers value flexibility, reliability and low cost when choosing transportation. These same criteria are important when selecting the radio communication system.

Ready for the broadband future

Choose a TETRA radio communication system and keep your transportation network running smoothly.

Complement it with broadband and adopt a hybrid network: use the TETRA network for critical voice and data and introduce mobile broadband services step-by-step.

3 vital requirements

1 - Keeping in touch.

Drivers are on the move and change cells frequently. They may work on a different vehicle or train every day and even switch them during a shift.

TETRA systems from Airbus can meet all these needs.

2 - Excellent coverage.

For metros in particular, radio coverage is also needed in tunnels, which limit the propagation of radio waves.

What's your best option for indoor radio coverage? There are three options to set up radio coverage indoors.

3 - Reliable contact.

Whether operating on the ground or underground (or both), safety demands instant, reliable, two-way communication between drivers and dispatchers, stations and security personnel.

Number one secret technique

What is the number one secret technique for improving communications in a transportation company?

Lionel Marciano from Airbus gives a valuable tip for a transportation company.

He shows how a metro company or a railway company could improve the communications and collaboration among and between work teams.

How TETRA is used in railway and metro

Railway and metro operations are very similar, the main difference being the tunnels through which metro trains travel and where radio coverage needs careful planning. In some cases, the same company operates both, like RATP of Paris. RATP can be both efficient and secure with the help of its integrated TETRA network from Airbus.

A typical railway and metro line includes

  • an Operations Control Centre (OCC),
  • base stations in each metro station,
  • radios in each train and
  • passenger communication.

Each of these elements is linked through the TETRA system, connecting security guards to conductors via radio, for example, even when the train is deep in a tunnel; or allowing operations managers to simultaneously alert passengers and metro station workers to an emergency.

For example, in Dubai, the metro trains operate without drivers, so it’s imperative that the OCC can make announcements directly to the passengers.

A fine example of TETRA success in Asia is the Shenzhen Metro 800 MHz TETRA network delivered by Airbus. The largest metro integrated TETRA network in the world, it covers five metro lines running throughout Shenzhen city, with an average daily passenger flow of around two million.

The same reliable TETRA network can be used for different purposes, from train scheduling to security notifications and passenger information.

Special applications

Special applications are effective at streamlining dispatching. For example:

  • Semi-conference group call. Group members can hear the dispatcher, but only the dispatcher can hear group members. This special feature is available in Airbus TETRA systems. 

  • Location-based group call. It is very useful to be able to define communication groups by location - for a certain train station or metro station, for example. This is also a special feature unique to Airbus TETRA systems.

    A location-based group call starts when the user pushes the PTT button. The system automatically checks her/his location and sets up any group calls to other members in the same place. In other words, the user always “sees” and uses the same group, but the system gathers together the correct users each time they make a group call.

  • Integration. It is possible to integrate the radio network with the trains' onboard computer systems, allowing downloading of route plans and other data.

    It is also a benefit to be able to use the same, reliable TETRA network for different purposes, from scheduling a train’s arrival at a station, to security notifications and passenger information, all of which can be accomplished with one system.
