50 powerful reasons for adopting hybrid solutions

What is TETRA radio system?

What is the true meaning of TETRA?

TETRA is an abbreviation of Terrestrial Trunked Radio. It is a standard by ETSI, European Telecommunications Standards Institute, which defines a digital system for professional mobile radio communication.

TETRA radio communication networks have many advantages over the first, analogue generation of wireless communications. TETRA networks are designed not only for voice, but also for narrowband data, and group communication functionality is built into the core system. They are safe from eavesdropping and Direct Mode Operation (DMO) makes it possible for devices to communicate between devices (radios) without a network.

Airbus provides TETRA radio communication systems based on this proven TETRA standard.

Did you know? A system may be standard, but systems by different manufacturers can do different things. Choose a TETRA system from Airbus and get the best benefits.

TETRA communication is easy for the users:

  • They press the PTT key on the radio to talk to a group of people
  • One click, and the dispatcher can talk to everyone
  • Background noise is filtered out
  • There is the red key for personal emergency
  • … and many more

And there's more -

  • Communication security: organizations in the system stay secure and private from each other
  • The security features will meet your requirements
  • Data communications do not require a different device
  • If you are keen to get your money’s worth, Airbus has designed its TETRA systems to be economical to operate. This is a clear advantage when you consider that operational costs can be up to 80 % of the total lifetime cost of the system.

Plus, TETRA offers a smooth evolution to broadband

You won't have to replace your well-serving TETRA system to bring broadband into use. Instead, you can evolve your current network into a hybrid TETRA and LTE network.

FAQ - Frequently Asked Questions

Who uses TETRA radio communications?

TETRA is the world’s most used digital PMR standard, deployed in approximately 130 countries. User groups vary from nationwide public safety agencies and utility companies to industry plant installations with just one or two base stations.

TETRA technology is extremely practical for organizations in public safety, transportation, healthcare and medical teams, enterprises, and various industries. They all need to communicate within teams and between them, and they need these solutions to be mission-critical: available, reliable, and secure.

These are just a few examples of Airbus TETRA System customers:

Airbus is committed to maintaining these systems for years to come. This guarantees that the TETRA system develops for a long time. Take a look at more customer stories:

How good is TETRA coverage?

Coverage depends mostly on the frequency used and the transmission power. Receiver sensitivity is also important. As TETRA is an open standard, competing vendors have continuously brought innovation to TETRA’s development so that today, using the same frequency band with similar output power, TETRA coverage is outstanding.

Did you know?

  • The TB3-series base stations are the most popular in the world. For example, the coverage for the world's largest TETRA network (BOS network in Germany) is built with TB3 TETRA base stations.
  • The hybrid base station TB4 is ready for broadband. It can handle both 4G/5G and TETRA technology.

Can a TETRA network be connected with other technologies?

Airbus TETRA systems connect analogue and digital group call services using the Generic Four Wire interface. There is an interface for one-to-one calls for connecting to an organisation's PABX, to PSTN or cellular networks, as well as interfaces for connecting SDS (the “TETRA text messages”) with cellular networks and IP data traffic with data networks.

Typically, all legacy network services can be interconnected.

What's more, you can adopt smartphones and other broadband solutions and connect them very effectively to Airbus TETRA systems. Such hybrid solutions are a smooth way to mission critical broadband.

Who have adopted hybrid solutions?

Many organizations around the world use hybrid solutions from Airbus to complement their narrowband TETRA with broadband 4G/5G. These are just a few examples:

What does TETRA over broadband mean?

Is 'TETRA over broadband' even a thing?

There is an ever-growing trend with professional organizations using smartphones in their work. They want to take advantage of broadband and multimedia communications.

TETRA over broadband makes it possible for the radio user to have a group call also with team members who carry a smartphone. Learn more in this blog post: “What does ‘TETRA over LTE’ mean?” 

What about TETRA and smartphones?

The smartphone trend also means that one person may have to use a TETRA radio AND a smartphone for work. Two different devices means different procedures and different functions. Carrying two devices is not ideal.

So, could TETRA features be brought into a smartphone?

There are apps that put a PTT button on the smartphone screen. Some smartphone models may also have a physical button that could be dedicated to the PTT function. This is great for many users, especially when the push-to-talk application is designed for professional use.

Take a look: This blog post explains how to recognize a professional push-to-talk application.

Let’s say your organization has decided to adopt broadband and apps for professional use. How do traditional radios and radio communication fit in? How does TETRA fit with smartphones? Learn more in this blog post: “How to use TETRA and smartphones in a hybrid way”.

TETRA in a smartphone?

The natural way to use a device in push-to-talk communications is to hold the device in one hand and operate the PTT key with one finger of that same hand. The button in an app is not as comfortable to operate in this way.

A good solution is to choose suitable accessories (gadgets) for the smartphone. Another solution is to adopt a hybrid device – TETRA in a smartphone, in a way.

The best choice for your secure push-to-talk and push-to-x communications is the professional Agnet app.


Hybrid device

Tactilon Dabat is a TETRA radio AND a smartphone. It is a hybrid TETRA+LTE device, designed for professional, every day, all-the-time use. It has a touch-screen to use apps, but is also designed to allow voice communication without touching the screen. It is comfortable to use also while wearing gloves.


Does your company use TETRA for secure communications? Make your system future-ready by adopting the Agnet TETRA push-to-x smartphone app. It works seamlessly with Airbus TETRA systems, and you will not have to change existing talk groups, processes and systems.
