YT- Communication Offers Popular TETRA Radio System For Secure Data and Voice Transmissions

YT- Communication offers the Terrestrial Trunked Radio (Tetra) mobile radio to professional users so that data and voice transmissions are secure. Tetra is regarded as the worldwide standard for digital trunked radio, and has an array of features that promise to adapt to the needs of the user.

YT- Communication is often seen as one of the best TETRA radio system manufacturers available. After all, they offer an array of products and services that includes TETRA portable and mobile radios.

The European Telecommunications Standards Institute came up with the TETRA standard, and is for the digital mobile radio. The TETRA mobile radio networks work under international standards so that professional users – authorities, energy suppliers and more – can have the reliable radio communication.

Why are they so popular? It’s because they are available and can handle challenges that applications present it with, which also include mission-important situations. Therefore, TETRA radio network can deal with and handle potential infrastructure component failures. They can also work on their own without public mobile radio network that are used for daily communications with mobile phones.

If the network is faced with an overload (think an emergency or catastrophe), the TETRA radio network is available for emergency responders and other services to use for communications.

What Kinds Of Services Do TETRA Radio Systems Have To Offer

There are all kinds of services offered by TETRA radio systems, including providing an array of voice and information services that are well-ahead any analogue radio technologies and orthodox GSM telephony can offer.

  • Group Call – This allows a certain group of subscribers to talk to one another at the same time.
  • Pre-Emptive Calls, Emergency Calls and Call Priorities – This allows TETRA subscribers to call other subscribers on the network, even with their different priorities. If a radio subscriber’s call has been cut off, it’s then given to the highest priority within that network resources. Low propriety calls are set up into queues.
  • Security and Encryption – TETRA radio solutions provide support to numerous security apparatuses to ensure in-depth radio communication protection and to reduce the chance for outside interception of the data.

A Look At The Data Transfer

TETRA standard radio systems offer the amalgamation in services for mobile data transfer and trunked radio. What does that mean? Simply put, the information is transferrable in conjunction with voice communication. The standard ensures the transmission of packet data right from the start with the Packet Data Service. For instance, status information is exchangeable from the TETRA radio equipment to the control systems.

In order to attain a high data transfer speed, the TEDS (TETRA Enhanced Data Services) considerably boosts the maximum potential transfer rate. Therefore, it ensures that an array of applications can send high-resolution pictures or stream videos via the TETRA network.

TETRA’s Future: Where Does TETRA Go From Here

In the past, TETRA was extremely slow in its data transfer, but has become a wideband data known as TEDS. TEDS offers higher data rates that can extend well into several hundred kilobytes and fits into the existing PMR frequency backdrop.

This standard carries out an array of important mission critical communications necessities. It deal with Public Safety organizations, but still offers private organizations a radio systems that includes data and voice capabilities.

The next huge advancement in TETRA is the amalgamation of broadband technologies, offering even higher data rates than what is seen today. It’s possible that the sending of high-res video will be possible with the technology today.


LTE has become the widely accepted form for broadband information communication in the public mobile radio business sector. And, it’s quickly become the accepted form for TETRA’s future. What is LTE? It’s the data pipelines where various services can be realized in a service- focused manner. LTE does have some similarities with TEDS such as:

  • Delivering pocket data channel
  • Rich multimedia application to end user devices

A Look At The Broadband PMR Drivers

Numerous public safety and utility and transport organizations are in need for multimedia data applications to streamline their daily operations.  It’s for this reason that the IP-based broadband data service was created. It boosts the productivity level of an array of mobile data applications.

Look at it through the public safety industry. Broadband service provides an officer more awareness of the situation around them or where their officers are at.

It’s parallel to the public mobile radio industry, with apps that go into the PMR segment and are used to come up with modified tools for customers to use in their daily operations.

It all offers the following things:

  • Complete e-mail capabilities
  • Video conferencing
  • Internet/intranet browsing
  • Better online access to databases

Understanding How TETRA Is Used In Mission Critical Communications

In order to meet the day-to-day business demands TETRA users have, there must be a pertinent-level of privacy and security as well as PMR specific services.  It is imperative that PMR networks have the best service and network availability, to reduce any stand-alone modes or redundancies. Even when this cannot happen or when there is no available network infrastructure, some type of peer-to-peer communication must support the end-user devices.


Therefore, public networks are only useful in applications that have a non-emergent nature to them. Public technologies will need to be altered to ensure the happiness of PMR operators and users. The end-user equipment must be durable so that it can be used extensively.

What’s The Spectrum For The Tetra Devices

While broadband and wideband systems generally use the innovative and adaptive channel coding methods, the higher data rates are more in-line with the RF spectrum.  Since the LTE doesn’t align with existing PMR frequency bands and needs a minimum of two 10MHz to offer a reasonable performance in the usual public safety situations, the newest spectrum can be used.

The U.S. has chosen the 700MHz LTE for important information applications for its public safety organizations. Other regions have yet to choose their frequency brands on the broadband PMR, but it’s though they will also assign channels to the 700MHz band.
