LoRa 4G Wireless Gateway

ZW-NR300 is an IoT LoRa wireless 4G gateway that utilizes 4G networks to provide users with wireless long-distance data transmission capabilities, while utilizing LoRa wireless transmission technology for self-organized network data transmission. Supports TCP/IP, MQTT protocols, self-developed networking protocols based on TDMA, CDMA, FDMA, and standard ModBus protocols.

Product details

The NR300 LoRa gateway manages the communication of LoRa terminals in this area, and connects the LoRa terminal data in this area to the server through a public cellular network. ZW-NR300 provides RS232, which can be directly connected to serial devices to achieve data transparent transmission; It can achieve functions such as digital input and output, pulse output, analog input, pulse counting, etc.

This product is widely used in the M2M industry and is widely used in the IoT industry chain, such as remote meter reading, smart cities, smart factories, smart buildings, smart firefighting, smart parking, smart homes, industrial control wireless transmission, and other fields
