In principle, the two wireless signals would interfere with each other of course, or the signal further away could be lost. But unlike other wireless switch technologies, the EnOcean signals are repeated twice within about 30 milliseconds for greater data security, with the delay between the transmitted bursts being randomly controlled. This very fast and short multiple transmission enables many transmitters to work in parallel in tight confines on the same frequency and with an extremely low error rate. Statistically seen, even with 200 wireless sensors each transmitting once per minute, the possibility of a data collision is every 10,000th transmission.
