How does tetra radio work

It has many features for safety and emergency use. Its scalable architecture allows deployment in networks ranging from single-site local area to multiple-site wide area national coverage.

TETRA provides an open standard technology. It features a dedicated control post to monitor communication along the line. The TETRA network allows users to create dedicated workgroups and dynamic groups, which are managed by the control post in case of any event or crisis situation. Equipment redundancy and radio coverage redundancy in the TETRA network ensures system availability while communicating with all stations and tunnels and links them with the command post.

This mode allows switching between speech and data transmissions, and can even carry both by using different slots in the same channel.

Full duplex is supported with base station and mobile radio unit frequencies normally being offset by about 10 MHz to reduce interference levels between the transmitter and receiver in the station to an acceptable level. DMO is used for direct communication between two mobile units and supports both voice and data; however, full duplex is not supported in this mode. For example, video footage from drones, video from CCTV cameras, social media feed analysis and data in a variety of databases can be used to complement the information that people on site provide in their communications.

This makes it easier for those in command to make the right decisions. They can also anticipate and prepare for what may happen next. Field users will be better aware of possible risks as well. Smartphone users. Some of the people involved in operations may not be carrying a radio.

But a proper hybrid solution makes it possible for radio users and their smartphone-carrying colleagues to communicate seamlessly. This allows situations to be managed effectively. Examples include contacting a medical expert to provide a rapid diagnosis or a city official to warn citizens about a dangerous situation. Professional apps. Giving people in the field access to critical information in databases or being able to validate a passport using either a radio or a smartphone are examples of professional applications that can help public safety organizations fulfil their obligations every day.

New data services. Traditional radio networks such as Tetrapol and TETRA offer data services, but a hybrid network can offer completely new types of apps based on broadband data: real-time multimedia information with mission-critical priority and security, for example. Visual information for better decision-making. A broadband connection lets users share multimedia with colleagues or dispatchers. Smartphone users everywhere have learned to use photos and videos taken on their phones for all kinds of purposes, from pictures and video for evidence or for making video calls with colleagues.

Multimedia is increasingly used with automatic video analytics to detect and identify people through facial recognition and to identify vehicles by their type, color or registration plate. Cameras have already opened great new possibilities for public safety professionals, and in a hybrid environment, storing and sharing photos and videos can be controlled by the user or performed remotely or even automatically.

Video, online sharing or evidence for reporting. A video can be a personnel safety issue — for example when the dispatcher or field commander, with help of artificial intelligence, can observe a situation via a live feed from a video camera and send back up when needed.

Videos can be analyzed automatically and, when necessary, share the essential aspects of a current situation to all teams involved in the incident, with the same video used as evidence in reporting. Going hybrid. Popular solutions. TB4 hybrid base station. They are ideal for hybrid solutions. One of its many uses is for implementing specific applications, such as positioning solutions or telemetry systems. Tactilon Management. Reliable with excellent coverage.

The network is reliable every day but also also in exceptional circumstances Your users will appreciate the excellent radio coverage without black spots They will see and hear a clear indication if their radio should lose its connection.

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 -. 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.
