When you need to access your devices from several WAN or Internet based dispatchers.
The RadioServer will set up all the TCP connections you need.
Using the RadioServer
The Mimer RadioServer is needed in larger systems were TCP is used (usually when running over the Internet). Since the Network Interface only can connect to one dispatcher PC at a time.
(In local systems using UDP to connect, you can have many operators without a server)
The number of connected dispatchers can be expanded by installing a Mimer RadioServer at the base station site.
The server can also be installed at a dispatcher central to distribute radio resources to other dispatchers over the Internet.
This is perfect when you have for example a taxi company with local dispatchers during the day and remote at night, or dispatchers that need to work from home.
The Mimer RadioServer Mk3 has a capacity of 256 connections each configurable for radio or dispatcher. Like this:
- 2 radios x 128 operators
- 4 radios x 64 operators
- 8 radios x 32 operators
- 16 radios x 16 operators
- 32 radios x 8 operators
- 64 radios x 4 operators
- 128 radios x 2 operators
The older version had a capacity for 64 connections.
The Mimer RadioServer Mk3 is delivered as a self contained small Linux computer running on 12VDC. It will start by itself if there has been a power failure. It has low power consumption and is easy to install also with power back up.
Mimer RadioServer is, as standard, delivered pre-installed on a CF-card mounted in a compact industrial x86 computer, as seen to the right.
However, it can also be delivered as an OVF- file to be run on a virtual computer using Oracle Virtual Box. The Virtual box will be set to run a 32-bit Debian Linux machine. The virtual disk will be 2GB in size and allocates 512MB of RAM.
The current virtual machine file has been created and tested using Virtual Box version 5.1.26
It is now also tested for use on VMWARE.

We gather technical questions and answers on this page!
Setup instructions can be downloaded from the technical download page.
RadioServer – Web browser setup
RadioServer – Web browser status window
Web browser setup menu
The Mimer RadioServer has a web browser based setup interface.
All settings of connected radios, IP addresses etc are easily done through a standard web browser.
There is also a file of old settings so that it easy to revert to a previous setting.
Web browser status window
The Mimer RadioServer has a web browser function were you can connect and see the status of the server.
You just need to browse the IP of the server and it will give you information on connected radios and connected operators.
It will also show if an operator is transmitting.
No changes can be made to the server from this interface, it is “look only”.
High latency and high jitter?
Use our Satellite version of the Radio Server!
Already in the standard version of the Mimer RadioServer, much higher levels of latency and jitter can be handled than in the Network Interface.
For connections with extra demands there is also a special version of the RadioServer that improves this even more. Recommended for users with Satellite connections and/or VPN tunnels.
When using the satellite version you always need a Mimer NetworkRepeater at the dispatch end.

Showing some different examples where a RadioServer in needed.
Connection with a Mimer RadioServer at the base station site.
The server can handle one or many radios at the same site and many dispatchers at different places.
Showing two of the radios connection through UDP to the RadioServer and two of the operators connection through TCP to the RadioServer.
Example with several police stations with their own small systems. They are also connected together through their own WAN. With help of the RadioServers, operators at other police stations can remotely connect to each others radios.
In this case for operating a remote Tetra radio in DMO if the Tetra net does not function.
