15 EnOcean RF networks
15.1 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 m / 1000 ft (in a free field). The secret is the signal duration is just
one thousandth of a second and triggers, executes and concludes the entire
process.

Summary of EnOcean RF standards (http://www.enocean-alliance.org/en/enocean_standard/)
High reliability · 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 m / 100 ft in buildings & 300 m / 1000 ft unhindered.
· Repeater available for extensions.
· Uni and bidirectional communications.
Low energy demand. · High data transmission rate of 125 kbps.
· Low "data overhead".
· ASK modulation.
