World’s first radio modem with Internet access

12 January 2009

Radio modems communicate wirelessly with each other across a range of up to tens of kilometres. In addition to power, no infrastructure (base stations, satellites, etc) is required. Radio modems for both unlicensed and licensed frequency bands are available.


Now Finland-based SATEL says it is launching the SATELLAR Digital System, which is a smart radio modem combining TCP/IP-functionalities, a Linux platform for customer specific applications, all in a modular structure.

The company claims its new product goes beyond the radio modems that have conventionally been used to simply convey data. These modems are essentially used to replace a cable in inconvenient locations.

The central unit of the SATELLAR Digital System, one of the three modular units, is essentially a computer with sufficient processing power and memory to run sophisticated software applications in addition to the operating system, IP-router, and web configuration server.

This means that fewer devices are needed on site, lowering costs and complexity.

Tuomas Pitkänen, CEO of SATEL, says “Our radio modems are known for their reliability to transfer data wirelessly in critical systems.

“Now we are able to go much further and provide an environment for developing the right applications our customers need for their systems.

“At a wind power plant, for example, a SATELLAR network can monitor and control all wind turbines and allow an operator to adjust turbine settings from his office in a different part of the world.”

Modularity is another aspect in which SATELLAR brings a “paradigm shift” to the radio modem industry, he says.

The SATELLAR digital system offers different units – building blocks – that can be combined to construct a radio modem with the right functionalities for the specific location in question.

The radio unit, which is the basic building block, can alone be used to access RS-232-based devices, for example, or act as a radio repeater.

The central unit, with its TCP/IP-capabilities and a Linux platform, can be added to locations where more functionality is useful.


Furthermore, it is possible to add standard or customer-specific expansion units – even after the initial deployment, as an update. Details on expansion units will be given by SATEL when SATELLAR is commercially available, i.e. in the second quarter of 2009.

“SATEL is very proud of SATELLAR. In addition to bringing new unforeseen features to the radio modem market, we have been able to increase the performance of radio itself, bringing radio modem performance to a completely new level,” commented founder and board member Pekka Aura.

SATEL, with headquarters in Finland, specialises in designing and manufacturing radio modems for long range wireless data communication. It has been in business for over 20 years, and has provided radio modems in applications ranging from Mt Everest to nuclear power plants and from professional motor sports to runway telemetry at airports. The company has distributors in over 50 countries.
