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.
