Three clever features

Three clever features for your radio network

You don’t have to be fascinated with base stations or other equipment to appreciate these three clever features.

What makes them special? They are based on the radio network and the radio devices working together in a synergetic way.

Avoid heavy traffic

Your radio may know how to avoid heavy traffic on the radio waves

When load-directed roaming is enabled in the system and radio terminal, the terminal can avoid cells with high traffic loads, opting instead to use less heavily loaded cells nearby.

How does it work?

According to the TETRA standard, base stations broadcast their load status to radio terminals. The load may be low, medium, or high. In load-directed roaming, radio terminals are allowed to choose a less loaded cell, even if it has lower field strength. These radios can get a connection while other radios are put into a queue.

Win-win benefits

Better for users: better availability means important communications can get through

Better for the network operator: a smaller number of sites is needed to support a larger number of users because the load between the base stations is shared

More out of your battery

Your radio may be able to save battery power

Enabling the energy economy function in a radio terminal can make the battery last 10 percent longer without compromising on usability or the availability of services.

How does it work?

As a rule, TETRA radio terminals listen to the control channel all the time and this consumes power. But it is possible to prolong the standby time by getting the radios to listen to the control channel at intervals, instead of all the time. In between they "sleep".

Users benefit -

Better for users: radios don’t run out of power as quickly

There are also other ways to make the battery last longer. Take a look at these seven ways to extend the battery life of your TETRA radio battery

Better audio on the move

Communications do not have to break when moving from cell to cell

When the system and radio terminal both use Type 1 Handover, connections continue unbroken, even when users move from cell to cell.

How does it work?

Without Type 1 Handover, radios need to register with each new cell and thus become unavailable for 0.5-1.5 seconds every time they hand over.

Radios with Type 1 Handover synchronise themselves with a new base station as soon as it is detected, so they are ready to communicate as soon as the switch from cell to cell takes place.

Users benefit -

Better for users: instant handover improves audio on the move

How to adopt these features

Airbus TETRA systems of Release 4.0 or later, including their infrastructure such as the switches and TB3-series base stations support these features.

And of course all Airbus TETRA radios now in deliveries support  these features as well.

These three are just some of the great possibilities that open up when the radio network and radio terminals both support features in an optimal way.
