Houston: a mobile app to replace a radio communication system

Bring your company radio system to the 21st century using VoIP and mobile applications to improve communication quality while reducing costs.

With the project Houston, we took the challenge of replacing the old radio network of the Transports Publics Fribourgeois (TPF), a swiss public transportation company by a system using existing data network and running on mobile applications. This solution solved the problem of maintaining a dedicated radio network. It also improved both the global quality of the communication and the availability of the system.

Initial situation: communication based on radio system

Since decades, employees of the Transports Publics Fribourgeois (TPF) have been using standard radio to communicate between them. The radio system is meant to cover the needs of the users. It is spread over more than 200 busses, 30 team leaders and the operation center). There are three types of users, with specific needs:

  • The operators – working in the operation center – use the radio to speak to a specific bus driver, or to broadcast messages to all or part of the running busses.
  • The team leaders are dispatched at different locations. They use the radio to manage daily events – such as the replacement of a driver – or to inform many drivers of a change in the network – for example in case of an accident.
  • The bus drivers use the bus radio as the main means of communication while driving. They can call other busses, the team leaders or the operation center.
