LE modules operate in the 433 MHz and 868 MHz ISM license free frequency bands with tx power up to 25mW

They organize in a “Star Network” topology over a Telit proprietary protocol ideal for use in replacing communication over cables such as RS485 links (Profibus, Modbus) and half-duplex RS232 links (transparent mode), with wireless technology

They can also be used to create communications networks in a star topology and for long-chain communication with the new smart repeater function

Pre-certified RF modules, LGA xE Form Factor, TTL RS232 interface Excellent RX sensitivity Hayes mode or ‘AT’ mode for configuration Listen Before Talk (LBT) for collision avoidance Cyclic wake up: wakes up periodically and listens to the radio link AES128 data encryption available Repeater mode (bridge function) Download Over The Air (DOTA) Industrial temperature range Key Benefits For ultra low-power, low-latency applications Ideal for upgrading cabled applications with wireless technology Wide area coverage Good for battery powered applications Range : up to 2000m
