Welcome to the TRL Funksysteme website

We offer bidirectional radio modules for use in the license-free ISM band. Our products are developed according to today's industry standards and deliver the highest quality at competitive prices.

In addition, our OEM modules can be integrated into customer applications with minimal time expenditure. Thanks to our hardware and software developers, we can also offer you customized modules, everything from simple point-to-point connections to network-capable wireless systems.

Our technologies and developments are based on over 30 years of experience in the radio sector. Our product range extends from OEM modules to RS-232 radio modems and CUW (Central Unit Web) modules.

We also sell the radio remote control "Sesam" and "Remotus" from Åkerströms as well as the complete "smd" product series.
