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

RFicient® is the solution for 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

In addition to RFicient®Basic, we develop ultra-low-power solutions for localization of objects, decentralized acquisition of radio signal spectra (RFicient®Scan) as well as detection of radio signals of certain wireless standards (RFicient®Spot).

Development Services

Our range of services stretches from evaluation and feasibility over IC-Design, ASICs and IPs, System Design, Customer Support and Consulting to Datasheets.

Evaluation and Feasibility


ASICs and IPs

System Design

Customer Support and Consulting




Basic functions, frequency bands and additional functionality can be modified to fit the customers' needs. Fraunhofer IIS provides the ULP receiver technology as an IP block, which can be transferred to various CMOS technologies.

The RFicient®Basic technology will be available in 2019 as a stand-alone chip.
