Mimer SoftRadio for remote control of radios over IP

Mimer by LS Electronics – Connecting Airports Globally

LS Electronics is a Swedish technology company with over 30 years of experience in critical communication systems. Our flagship product, Mimer Softradio, is trusted in over 70 countries, helping airports unify voice communications across diverse technologies and brands.

Seamless Communication in the Airside Maze: Solving the Multi-Radio Puzzle at Airports

Airports are among the most complex communication environments. On any given day, ground handling crews may be operating over analogue VHF, air traffic control over UHF, emergency response units on TETRA or P25, and security services using encrypted trunked radios. Add in coordination with airlines, maintenance crews, and public safety and the communication landscape quickly becomes a fragmented mix of incompatible radio systems.

This fragmentation isn’t just an operational inconvenience, it’s a safety risk. Delayed messages, split situational awareness, and misrouted calls can lead to lost time and increased stress in high-stakes environments where clarity and speed are paramount.

Radio over IP (RoIP) is changing this. Our solution, Mimer Softradio, converts conventional radio signals into digital IP streams, allowing multiple radio systems regardless of brand or frequency to be accessed, monitored, and controlled from a single screen.

This means your tower operators, dispatchers, and command centre staff can:

  • Listen and speak across any connected radio network
  • Monitor multiple communication groups in real-time
  • Control and switch radios without ever touching physical devices

And it doesn’t stop at radios.

Mimer can also integrate PA systems, VoIP telephony, and intercoms. Operators can make paging announcements, patch phone calls into radio groups, and connect with airside teams via headsets or handsets — all from the same interface.

We support over 60 radio models from leading brands like Motorola, Sepura, Kenwood, Icom, Jotron and more, making it easy to deploy Mimer in mixed environments without replacing existing infrastructure.

For airports with advanced IT capabilities, we offer a powerful API, allowing our RoIP engine to be embedded into your own command-and-control systems. For others, our turnkey Softradio GUI offers an intuitive control panel with virtual radio faces, customizable layouts, and operator-ready tools.

Whether your airport serves a few flights a day or thousands, Mimer brings everything into one view, improving collaboration, reducing miscommunication, and making airside operations safer and more efficient.

At airports, every second counts. And every voice matters.

Airband Radio Systems

Large Airports

Large Airports are a perfect environment for SoftRadio.

Busy, busy, busy! All around an airport you have people and vehicles that need to communicate. With SoftRadio your operators can communicate with all types of radio systems including the air band radio to the planes. There are virtually no limits to what you connect into the SoftRadio system. Ground radio, Airband radio, Intercom, Phones etc.

SAS – Scandinavian Airline Systems

The largest installation of Mimer SoftRadio is used by SAS. They have connected all Scandinavian airports to a dispatch center in Frösundavik, Stockholm. The main connection is their own WAN system, but they also use public Internet for remote locations.

At each airport there is a ground radio system, at many airports old analogue channels in VHF or UHF and in the larger airports it is Tetra. At most airports there is also one or more airband radios. This means that the dispatchers can talk both to ground personnel and to approaching airplanes through the same user interface.

All audio in the system is also recorded through Mimer VoiceLog servers.
For backup reasons there is also an extra standby dispatch central at Arlanda Airport, that can be operational at short notice.
In total the system has about 50 operators and 60 radios spread out over Scandinavia.

Pilot add-on with PoC functionality

To make the turn around faster at the airport gates, SAS connects the pilots into the ground radio call that is ongoing around the airplane at the gate. However the pilots doesn´t use a standard two way radio for this, it would be to complicated since every airport has its own radio system. The pilots instead uses their smart phones and an application that connects them to the two way radio call. This is done with Mimer equipment and in cooperation with a company called GroupTalk.

Small Airports

A small airport or airfield is often unmanned, but a landing airplane still need to talk to Air Traffic Control elsewhere.

By using remote controlled radios, one operator can handle many airfields from one single location.

Working Remotely

Remote controlled Airfield radio


Remote dispatcher

Small airports and airfields are in many cases unmanned. If they are far away from a large airport with Air Traffic Control, they need to have their own radio to handle safe landings and take aways.

This locally installed radio can be remote controlled from a totally different place. All you need is an IP connection.

 

 

Night time watch from one common dispatch site.


Common dispatcher – Night watch

In the example to the left, the three airports each have their local small system with one radio and one dispatch PC. The three systems are also remote controlled from one common dispatch site.
This set up can be very useful for example when there is low traffic at night time, but you still need to monitor what is happening at the remote airport. One common dispatcher can then handle all three airports.
The system can be expanded with more airports, dispatchers and also other types of radios.

 

 

Radio Types

Virtual Control head of the Icom IC-A120, remote controlled airband radio

Fixed radios

The most common radio that we remote control, is the Icom IC-A120. It is remote controlled with audio and PTT plus channel change and squelch setting.

We can also remote Jotron radios with the same functions, and many other radio types, with only audio and PTT (fixed channel).

 

Portable airband radio connected to a network interface

Portable radios

Most portable radios can also be remote controlled. But only for audio and PTT, no channel change.

The drawbacks with using a portable are power through the battery (it needs to stand in a charger) and a small antenna.
