RFicient® - Ultra-Low-Power Receiver Technology
for the Internet of Things

RFicient® is the solution for all wireless applications that are designed to provide an operating life of several years with a minimal amount of maintenance.

The ultra-low-power receiver technology RFicient® continuously monitors a radio channel while providing a very low power consumption in the order of microwatts and reaction times in the range of milliseconds. This enables around-the-clock operation of wireless applications and increases their operating life significantly - up to ten years without battery replacement or even fully autonomous operation via energy harvesting.

RFicient® Ultra-Low-Power Receiver Technology - Portfolio

Minimal amount of power consumption is one of the most important criteria for future IoT applications. Continuous wireless connectivity consumes a major part of the available battery power and operating life of IoT-nodes is extremely limited.

The entire RFicient®-Portfolio enables long-term ultra-low-power connectivity. In addition to RFicient®Basic, the portfolio consists of solutions for decentralized acquisition of radio signal spectra (RFicient®Scan) as well as detection of radio signals of certain wireless standards (RFicient®Spot).
