Connecting radios all over the world

Mimer SoftRadio - Large 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.

Systems with different types of radios connected.

Bus companies as well as taxi companies often have local dispatch centrals for a geographical area. In the night time when traffic is low they often collect their personnel to one central. With SoftRadio it is easy to connect all radio systems into one place. The radio systems can be of different kinds, like in the example above.

The radios can be connected over a WAN, like above, or via the Internet.

Oil rigs have large needs for radio communication. They use a number of different systems. For the onboard communication it can be analogue, DMR or Tetra. On top of that are Airband radio and Marine radio.

Connecting all systems into SoftRadio makes it possible to communicate with all users from each dispatcher. It also makes it possible to do the same from remote users, for example at a second dispatch central on shore.

Typicaly the onboard communication portables are ATEX radios since the environment is an explosive hazardous area. But there are no Airband radios with ATEX approval. So when personel on deck needs to talk to an inbound helicopter they can ask a dispatcher to make a cross patch in the SoftRadio system between the onboard radio and the Airband radio, and then use the ATEX approved onboard radio and still be able to talk to the helicopter.

Also PA-systems can be connected to SoftRadio so that dispatchers can both make PA announcements and also listen to to the PA calls. A dispatcher that is on shore might have good use to hear what is said on the PA system on the platform. This can also be combined with cross patch so that personel using hearing protection will hear the PA calls through the radio system instead of the speakers.

Radio systems on several platforms can also be combined so that they can communicate together.

SoftRadio Bus dispatcher

Example from a centralised bus dispatcher.

SoftRadio oil rig example

Example from an oil rig with many radio types and operators both onshore and offshore.

SoftRadio windfarm example

Similar arrangement with wind power farms offshore and operators onshore

Same type of thinking works for offshore wind farms were many radios are used both during the building period and during the many years of producing electricity.

A system consists of many radio sites, each holding both Marine VHF, Airband VHF and Tetra or DMR radios. All of the sites needs to be remote controlled from centres onshore.

IP-connection to the offshore sites can be a mix of satellite, fibre or micro wave links.

Systems that are spread out geographically.

An example from the Swedish state owned casinos, Casino Cosmopol. There are four casinos and they are all connected to an operations center just outside Stockholm. From there operators can monitor everything in the casinos through hundreds of cameras.

For the operators to be able to talk to the guards and other personel at the casinos there are remote radios at each casino connected through their own WAN to the operations center.

Example build with radios spread out

Example with radios spread out. In this case also with different types of radios.

Many radio systems needs to cover large geographical areas. This can be done by connecting several spread out radios into the dispatch central.

If more than one dispatcher needs access to each base station over the Internet. It can be achieved with the help of a Mimer NetworkRepeater.

The base stations can be connected together through the use of Mimer CrossPatch making part of the system, or all of the system, into one large radio coverage area.

Security Dispatch

Typical setup for an MPT1327-system. Instead of each operator having one radio in front of him. Everyone can use all radios. The radios them selves are placed in a data rack instead of taking up desk space.

There is also an extra radio connected to a Mimer StatusLog that collects all status calls, alarm calls and voice call requests. Helping the operators to answer calls and alarms in the right order.

More fixed radios are located at other sites and accessed through the use of a Mimer NetworkRepeater.

A Mimer VoiceLog records all audio in the system.

Mimer SoftRadio at a security dispatch central


Two dispatch centres connected to large radio systems as well as a number of small systems in other towns and indoor in shopping centres.

Mixed types of base stations

  • One local base station working via a repeater.
  • One base station connected through a leased two wire line.
  • One remote base station connected with IP over the Internet.

This might be the set up for a taxi company in a small town, that also dispatches some other towns nearby. Different old type of radio systems that need to work together. To one base station ADSL can be delivered, to an other its not possible and the old leased line needs to be used.

Maybe the radios should be handled from each town in the day time and handled centrally in the night time. This can also be set up.

Mimer SoftRadio can handle the mix of systems needed to fulfil customer needs.

Example with different types of radio connections

 

The dispatchers have access to three different types of base station radios.

Command and Control Vehicles & Rapid Deployment

The vehicle can be both on land and on water. Read more on the Command and Control Page.

Rapid deployment example

Radios in a rapid deployment package that can be remote operated.

Above is an example of a rapid deployment system with two radios and one GSM phone. The system can be installed, and on stand by, in a flight container or in a vehicle.

Control can be done through a local dispatcher or a wireless local dispatcher.

The satellite link can be used for radio connection in both directions. Either the dispatchers “in the field” can access fixed radios, or dispatchers “at home” can access field radios.

The bandwidth of the satellite link will of course decide how many radios that can be accessed.

Temporary systems

We built a large Mimer SoftRadio system at the site of the World Scout Jamboree, held in Sweden in 2011.

The radio system itself consisted of 12 repeater channels, 24 simplex channels and over 1.000 portables plus a Scada system for pump alarms. Together with this a Mimer SoftRadio system with 12 radios, 20 operators and VoiceLog.

The system was used during WSJ, July 27 to August 8 2011, and for the build up and tear down periods, in total about 8 weeks. An event for 39.000 scouts from over 150 countries plus many thousand visitors.

SoftRadio has also been used at other temporary events in communication centres and security centres.
