Fujian Guanran Technology Co., Ltd. is a high-tech enterprise dedicated to the research and development, production and sales of whole-house smart home systems, smart hotel systems, and smart office systems. It has been committed to independent research and development for many years and has more than 20 national technologies. The patent and more than 30 appearance patents are based on international advanced technology as the standard. They have a complete set of solutions for smart home security systems, a complete sales network and a high-quality after-sales service system.

Its brand "GUANRAN" focuses on the research, development, production and sales of LoRa's smart home security system, smart hotel system and smart office system, so as to realize the feasibility of smart home products and smart hotel series products in various community projects, and for families and villas. Provide one-stop solutions for different types of community engineering projects such as real estate projects.

The smart home system independently developed by GUANRAN Guanran Intelligent uses a long-distance transmission low-power intelligent system built by wireless LORA chip imported by SEMTECH in the United States. LoRa smart home adopts point-to-point star communication method to realize long-distance transmission. , no grid repeater transmission distance is required, that is, intelligent accessories can be directly interconnected with the intelligent central control host, and there is no need for a large number of nodes in between to convey. Compared with other communication technologies, LoRa technology is more suitable for low-cost and large-scale objects. Network deployment; in addition, LORA has extremely strong anti-dry worry. LoRa wireless technology is a special spread spectrum technology. By using high spread spectrum factors, LoRa technology can transmit small-capacity data through a large range of radio spectrum, even if used The same frequency sends signals to the host at the same time and will not worry about each other, which solves the industry pain points of wireless technology that are easily disturbed; LoRa's wireless transmission distance is long, penetrating, and has strong wireless transmission stability, Guanran Smart Home System Wireless transmission is 500 meters, can pass through 5 solid walls, and LORA is extremely secure in wireless communication. It uses embedded point-to-point AES-128 data encryption technology, which solves the security of transmission between smart locks and gateways. question. The "wireless LORA terminal + wireless LORA gateway" independently developed and produced by GUANRAN Guanran Intelligent has become an ideal technology for large-scale promotion and application of the Internet of Things.
