Understanding EnOcean Wireless Technology

wireless technology enocean iot energy harvesting m2m

This page provides an overview of EnOcean wireless technology, a key player in the world of M2M (Machine-to-Machine) and IoT (Internet of Things). EnOcean stands out as an energy-harvesting wireless technology, achieving high data rates while maintaining low energy consumption. It’s designed to handle multiple devices transmitting simultaneously.

Notably, over 50 manufacturing companies have already developed approximately 200 EnOcean-compliant products. The technology is specified in the International Standard ISO/IEC 14543-3-10.

EnOcean Wireless Technology Basics in M2M and IoT

EnOcean system EnOcean system

The image above illustrates a typical EnOcean system. A key differentiator from other wireless systems is that EnOcean devices don’t require batteries for operation. Wireless sensors utilize motion converters, solar cells, and thermo converters for energy harvesting.

Furthermore, EnOcean efficiently manages energy to transmit information wirelessly using a minimal amount of power.

The EnOcean protocol stack is modular and versatile, allowing for easy integration of customer applications. A typical EnOcean chip includes an energy converter, energy management system, sensor, microcontroller, RF transceiver, and antenna.
