The CV5200 module high-speed and long-distance wifi wireless module focuses on the Internet of Things technology. Its innovative LR-WiFi technology (Long Range WiFi) solves the problem of low-cost, high-performance, high-speed, and long-distance wireless communication. Reshape the boundaries of WiFi transmission.
LR-WiFi: The main technology comes from WiFi, which not only has the characteristics of WiFi easy to use, mature, and can be networked, but also solves the missing problem in WiFi: distance.
LR-WiFi has a hundred times that of LoRa, zigbee and other narrow-band communications and a slightly lower rate than WiFi. It can also be compatible with WiFi through an external wireless network card. It can be widely used in wireless cameras, drones, smart buildings, smart agriculture, and wisdom. Fields such as factories, robots, stage and musical instruments.
