WS8485HMS is a LoRa frequency hopping module designed and manufactured by Silent Smart Technology Co. , Ltd. The module features eight adjustable air data rate steps, ranging from 2.4 kbps to 200 kbps.The maximum packet size is 192 bytes, with a maximum of 101 frequency hopping channels and a maximum hop count of 18.
The WS8485HMS uses LoRa ™ spread spectrum technology and a CSS+FHSS dual spread spectrum architecture, which has the advantages of long communication distance and strong anti-interference ability. At the same time, it uses random key encryption to encrypt data transmission, which has extremely strong data security .
It not only inherits the traditional advantages of LoRa technology, such as wide coverage and strong penetration, but also integrates advanced frequency hopping spread spectrum technology, achieving significant breakthroughs in anti-interference, security and reliability, making it an ideal choice for building complex industrial IoT applications.
