EnOcean - overview
Technology
The EnOcean radio technology makes a far-reaching signal with low quantities of ambient energy possible. With 50 µWs, a standard EnOcean radio module can easily transmit a signal over a distance of 300 m (in the free field). The signal period for an EnOcean telegram is approx. 1 thousandth of second.
- License-free 868 MHz frequency band with 1% duty cycle
- Multiple telegram transmission with checksum
- Short telegrams (approx. 1 ms) lead to a small probability of collision
- Long range: 30 m inside buildings or 300 m in the free field
- Repeater available for extensions
- Unidirectional and bidirectional communication
- High data transmission rates of 125 kbit/s
- Low ‘data overhead’
- ASK modulation
- Radio protocol is defined and integrated in modules
- Sensor profiles specified and adhered to by users
- Unique transmission ID (32-bit)
- No interference with DECT, WLAN, PMR systems etc.
- System design verified in industrial environment
