The setup of the transmission timing allows avoiding possible collisions with data packages of other EnOcean transmitters as well as disturbances from the environment. Standard EnOcean telegrams consist of up to 3 identical sub-telegrams which are transmitted within 40ms. The transmission of an average sub-telegram lasts approximately 1.2ms. The delay be- tween the three transmission bursts is affected at random. -
