Product Descriptions
E32-dTU (900L20) - V8 is a high-speed 868M wireless data transmission radio station (with RS232/RS485 interface), LoRa spread spectrum technology, transparent transmission mode, operating in the 862~930 MHz frequency band (default 868MHz), with a voltage range of 8V~28V.
LoRa direct sequence spread spectrum technology will bring longer communication distances and has the advantages of concentrated power density and strong anti-interference ability. The module has a software FEC forward error correction algorithm, which has high encoding efficiency and strong error correction ability. In the event of sudden interference, it can actively correct the interfered data packets, greatly improving reliability and transmission distance. In the absence of FEC, this type of data packet can only be discarded.
The module has data encryption and compression functions. The data transmitted by the module in the air has randomness, and through rigorous encryption and decryption algorithms, data interception becomes meaningless.The data compression function has the probability of reducing transmission time, reducing the probability of interference, and improving reliability and transmission efficiency
