Highlights of PTTconnect

Unlimited possibilities for your radio coverage

By using public UMTS and LTE™ networks or even WLAN, you are able to communicate with your colleagues way beyond the range of your TETRA radio network. 

All you need is a broadband data connection between your smartphone with the app installed and the Hytera connect server, which connects the TETRA radio system to public networks.

User-friendly and easy to operate

The Hytera connect server is administered via a browser-based web interface. The app is easy to use and has a particularly user-friendly design. PTTconnect can be used on Android devices and ensures seamless integration into your mission-critical work environment.

Secure communication

Both PTTconnect and the gateway to the TETRA radio system are interception-proof. Secure communication between subscribers in both mobile radio worlds is therefore ensured.

Immediate, direct communication

When you communicate with TETRA radio subscribers, PTTconnect establishes a direct connection to the services of the TETRA system. Features with which you are familiar from your TETRA radio system are supported by the app and therefore available on you smartphone, for example:

  • Individual calls
  • Group calls
  • Priorities
  • Emergency calls
