DelcomRF LoRa Modem

DelcomRF LoRa Modem is a wireless data transceiver with standard RS232/RS485 connectors. They are half-duplex. TX & RX modems with LoRa technology and transparent transmission mode. Voltage supply ranges from 8V to 28V, Working frequency: 410~441MHz (Default:433MHz).

The LoRa direct sequence spread spectrum technology enables the longer communication distance and better power density concentration as well as superior anti-interference ability. The FEC algorism enables higher coding efficiency and correction ability. The interfered data packets will be corrected proactively upon sudden interference, which significantly improves reliability and communication distance. Without FEC, the interfered data packet will be dropped. The transceivers feature data encryption and compression. The data transmitted in air features randomness, the rigorous algorism makes data interception meaningless. The data compression function has possibility to reduce the data transmission time, which in turn reduces the possibility of being interfered, thus improves the reliability and communication efficiency.

The main features are communication distance up to 15 km, addressable feature, 32 frequency channels, output power in European standards and RF networking over modems. Modem with dozens of different parameters are in the industrial class . It provides wireless data-data communication over very long distances by using modbus protocol over RS485 and RS232 ports. LoRa  (Long Range) is a modulation technique that provides much longer wireless communication distance than competitive technologies. It was developed by Semtech company. RFIC SX1278 LORA.
