LE51-868 S
The LE51-868 S is a high performance SIGFOX and CE certified module working on the 863-870 MHz license free band supporting both Sigfox Uplink/downlink communications and the Telit proprietary local network protocol. LE51-868 S, with up to 35 mW output power and -126dBm@ 600 bps sensitivity, is suited for short range to long-range applications such as asset tracking, energy or smart building.

Module Concept
LE51-868 S is used to create a local communications network in a star architecture and for long-chain communication with the new smart repeater function for long-range communication with a natural gateway to a Sigfox network. Ready to use and easy to handle the LE51-868 S offers data encryption (AES128), cyclic wake up (the module wakes up periodically and listens the radio link) and Download over the Air (DOTA) features.
