Over the last 3 decades, various attempts have been made to implement robust low-cost long distance connectivity for applications in the Low Voltage grid. We have watched all of those attempts end in frustration. Frustration with the cost and complexity of IoT, mesh RF and PLC local networks, as well as the difficulty to maintain and manage such solutions.

When looking at Ripple Control, many are charmed with the simplicity. It is no wonder why Ripple control (aka TF) has been and has remained so popular over such a long time. Ripple Control is easy to understand, easy to diagnose, and very useful for broadcasting a little bit of information over vast distances.

Off course, all that glitters is not gold. Ripple Control has severe issues. The cost is too high and there are problems with robustness and intrusiveness. And that little bit of information that can be send is very, very little indeed.

This was the starting point of DigitalTF. We were sure it had to be possible to combine the good aspects of Ripple Control (simplicity, long distance, broadcast, grid-tied) with the good aspects of modern communication technology (error detection/correction, low amplitude, speed, robustness), at a substantially lower cost. And we succeeded: DigitalTF improves upon Ripple Control by a factor of 10 in cost and performance. DigitalTF broadcasts 24/7 at 20 bits/sec, within the LV grid. We invite you to visit our Technology pages to learn more about DigitalTF. Please visit the Applications pages to learn how we envision DigitalTF’s use.

DigitalTF is an Intellectual Property company. Our business is the licensing of DigitalTF technology. Licensing fees can be determined by use case, by installation tier, or by geographical region.

For trials and design-in, we provide consultancy engineering at market-conforming fees. We can provide prototype transmitters, coupler/injectors and receivers.
