Evolve toward Brodband and IP

    Tetrapol network modernization

    Evolve towards broadband and IP

    After the revolutionary change from analogue to digital technology, PMR network operators and owners are experiencing the evolution to broadband communications and migration to IP technology.

    Tetrapol networks continue to give valuable service for another 15-20 years. Now is the time to modernize these networks, because network modernization

    • Ensures that the networks continue to bring value
    • Can save money in operations and maintenance
    • Further improves the network’s reliability
    • Makes it possible to offer new services to the users
    • Can evolve the network into a hybrid network
    • Migrate to an open IP architecture

    Network modernization is best implemented as a series of maintenance steps, not as a single large investment.


    What’s a hybrid network?

    In a hybrid network, public safety organizations will use Tetrapol services for mission-critical voice and data and get mobile broadband services step-by-step.

    The operator can offer the broadband services based on

    • A dedicated broadband network
    • Commercial services with the Secure Mobile Virtual Network Operator model
    • A combination of these two approaches

    Learn more from the white paper "The bridge to broadband - The best way to build a hybrid Tetrapol and LTE network".  The paper discusses the evolution of mission critical communications and the options there are for mission critical mobile broadband. It also explains how the transition to broadband can best be managed.


    Why modernize ?

    Tetrapol network modernization is a good idea when:

    • You want to offer your customers at least some of the same capabilities that people have on their smartphones
    • While you want to make sure your customers can enjoy mission-critical push-to-talk communication
    • And your customers want to be certain that they can continue to use Tetrapol communications at least for 15 more years
    • In addition, you want lower maintenance costs
    • And better reliability by replacing older equipment
    • Maybe your network is due for a mid-life upgrade as they are once in every 10-15 years.




    Tetrapol networks will continue

    The existing broadband networks, as they are today, cannot replace Tetrapol networks in mission critical communications because there are many unsolved issues. For example:

    • Standardization is not complete
    • Necessary group communication features are not available
    • Broadband networks’ availability and resiliency need to be further developed.


    It would not make sense to replace an existing well-serving public safety network with an alternative that does not meet the critical requirements.

    Tetrapol network modernization includes migration from TDM to IP transmission. This is the first step towards mission-critical broadband.

    Key components of Tetrapol network modernization

    IP migration

    Moving from TDM networks to Tetrapol IP. This is the first step on the path to mission critical broadband. IP migration is also necessary to ensure long term support for Tetrapol services.

    Tetrapol MBS

    Tetrapol MBS is the PMR-broadband integrated base station. The MBS is the smoothest way to introduce broadband services to complement the Tetrapol mission-critical voice.


    The path to hardware independence. New Control Node and Gateways are to run in a virtual environment.

    Tetrapol networks migrating to IP

    IP migration is underway in three nationwide Tetrapol networks:

    • RUBIS, nationwide network for the French Gendarmerie
    • Network for Federal Police in Brazil
    • INPT, nationwide public safety network in France
    • POLYCOM, nationwide public safety network in Switzerland
    • SIRDEE, nationwide public safety network in Spain
    • IRIS, nation public safety in Mexico

    IP migration is underway in several regional networks, such as:

    • Tetrapol network on Corsica, France
    • 30 shelters of the German Army
    • Bundesautobahn Rheinland motorways in Germany
    • Hamburger Hochbahn, public transportation in Hamburg, Germany
