The eDnode is a module for connecting equipment through eDevice's wireless local network for communication with eDevice’s eDgate which manages the communication between eDnodes and a TCP/IP network over PSTN, LAN Ethernet or GPRS.

The RF link between the eDnodes and the eDgate operates in the ISM 868 MHz / 915 MHz band with an FSK type coding, a bi-directional and half-duplex token-based dialogue. An 8 bit CRC ensures the control of data coherence. Each eDnode has a unique MAC address allowing automatic registration to the radio network on the gateway.  By default, the eDgate manages up to 16 eDnodes.

The range is better than 200 meters point-of-sight, and around 30 inside buildings.
