The LE51-868 S from Telit Communications is a SIGFOX RF module that operates in the 863-870 MHz license free band supporting both Sigfox Uplink/downlink communications and the Telit proprietary local network protocol. This CE certified module has a sensitivity of -126 dBm @ 600 bps, ultra-low power consumption and provides up to 15 dBm of output power. This module creates a local communications network in a star architecture and long-chain communication with a smart repeater function for long-range communication with a natural gateway to a Sigfox network. It provides data encryption (AES128), cyclic wake up (the module wakes up periodically and listens the radio link) and Download over the Air (DOTA) features. The module is well suited for short range and long-range applications such as asset tracking, energy or smart building.
