EnOcean customers are located all over the world. The interoperable wireless standard of the EnOcean Alliance enables switches, gateways and sensors from different manufacturers to combine seamlessly. In the world of automation, wireless and hardwired solutions aren’t in confict with each other; they complement one another. EnOcean wireless communicates with all major wired bus systems such as KNX, LON, BACnet or TCP/IP.

Patented EnOcean energy harvesting wireless sensor solution is able to generate a signal of astonishing range from an extremely small amount of energy. From just 50 µWs a standard EnOcean energy harvesting wireless module can easily transmit a signal 300 meters (in a free field). The secret lies in the signal duration - the entire process is started, executed and completed in no more than a thousandth of a second.

High reliability of wireless transmission

Reliable wireless transmission in systems with many sensors - the extremely short telegrams of EnOcean wireless modules enable operation of a large number of transmitters all in the same cell. Any error rate caused by telegram collisions remains extremely low. Ex-pressed in statistics, transmission reliability is still better than 99.99% for 100 wireless sensors each transmitting their data once a minute. In other words, even large office buildings or extensive industrial plants can be equipped with high numbers of EnOcean sensors, and all operating simultaneously.
