Technology

(This section is based on the document "EnOcean Range planning" by Engineer
Armin Anders, EnOcean LLC).
The patented EnOcean RF technology creates a surprisingly far-reaching signal
with remarkably little energy. So that devices can be operated trouble-free without
solar cells, Piezo elements or thermocouples.
The patented EnOcean RF technology creates a surprisingly far-reaching signal
with remarkably little energy. So that devices can be operated trouble-free without
solar cells (for room temperature sensors) or Piezo elements (switches/buttons).
At just 50 µWs, a standard EnOcean RF modules can transmit a signal over a
distance of 300 meters (in a free field). The secret is the signal duration is just one
one thousandth of a second and triggers, executes and concludes the entire
process.
Figure: EnOcean technology uses
• License-free frequency ranges 868 MHz or 315MHz at 1% duty cycle
(comply with local law/releases).
• Multiple telegram transmission with checksum.
• Short telegrams (ca. 1ms) results in a low probability of collisions.
• High range: 30 meters in buildings & 300 meters unhindered.
• Repeater available for extensions.
• Uni and bidirectional communications.
• High data transmission rate of 125 kbps.
• Low "data overhead".
• ASK modulation.
