Connecting radios all over the world

Mimer SoftRadio - Small Systems

Mimer SoftRadio can be built in many sizes

A SoftRadio system can be built in many sizes. Please also see the other pages with examples.

Operators can be local or remote, and also the radios can be local or remote, all in a mix. The radios does not need to be of the same brand or work in the same type of system, you can mix and match as you like. You can even mix with phones, intercoms and PA-systems into the system.

Below are a number of examples of systems in the smaller scale. All of them can be expanded at any time to any size needed.

Following are some examples of how to build small systems

Basic local system over a LAN

The most basic system is one operator and one radio connected to each other over a LAN. This can be expanded without any extra equipment, just add radios and/or operators.

Maximum number of local computers to one radio is 99. And the PC client can handle 8 radios or in the large version up to 30 radios.

Example with one operator connected over
a LAN to one fixed radio.

Two operators sharing three radios over a LAN

Example with two operators working with three radios.

Basic remote system over the Internet

Each network interface can handle one operator over the Internet.

To be able to connect more than one operator a Mimer RadioServer is needed.

Operator connected over the Internet to a radio

Example with one operator connected over the internet to one fixed radio.

Two operators connected to four radios with the help of a Mimer RadioServer

Example with two operators connected to four radios over the Internet via a Mimer RadioServer.

Basic System with mixed user connections

One radio can be controlled both locally (maximum 99 users) and through the Internet at the same time.

In the picture below the local radios rather short radio coverage is expanded through a radio repeater placed on a high position with good radio coverage. This is a common way to build the system. You don’t need an Internet connection at the antenna site and you can have many operators.

The operator over the Internet can for example be another dispatch central that takes over at night or it can be some one using the radio from his home.

Basic System with mixed radio types

Each operator can access up to eight radios (30 with SoftRadio XL). The radios can be of different types and brands in any mix.

In this example you have one Tetra radio, one DMR radio and one analogue radio. With the Mimer CrossPatch option you can also patch them together with each other.

Both local and remote operators working with the same radio

Example with two local operators and one remote operator all working with the same fixed radio that connects to the repeater.

Two operators working with radios of different types

Example with two operators working with three radios of different types.

Operators working through two localy installed Tetra units

Example with many operators working through two fixed local radios connected in the same LAN.

Basic System when you have no standard IP infrastructure

If you need to connect several operators to radios and have only copper wire access, you can use VDSL-modems to extend your LAN. Or you can use a wireless IP-link.

Same setup works with fibre cable, by adding fibre converters at each end you can extend your LAN.

In all examples no extra servers are needed since the system will all be in the same local subnet of the  LAN.

LAN extension through VDSL modems

Example with two operators working with two radios. Connection is done via a VDSL modem in an environment were there is no IP infrastructure available.

LAN extenstion through an IP-link

Example with two operators working with two radios. Connection is done via a micro wave link in an environment were there is no fixed IP infrastructure available.
