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

• 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 LE50-868 is over the air compatible with LE70-868 (500mW) in G3 868 MHz sub-band.
