LoRa is a long-range wireless communication solution. Compared with GPRS and 4G solutions, LoRa does not require monthly fees for network access, and the distance is farther than that of Wifi and Zigbe. Therefore, LoRa is becoming more and more widely used in long-distance communication with small data.
Shanghai ZLAN's LoRa products use SX1287 chip, using SEMTECH's LoRa™ patented modulation technology, which can achieve -140dBm receiving sensitivity and +20dBm output power, and the outdoor line-of-sight communication distance is 8km, with the characteristics of long distance, low power consumption and anti-interference. At present, ZLAN LoRa products are divided into two categories, one is serial port to LoRa, model ZLAN9700, it contains three serial port forms, namely RS232/485/422, and the other is Ethernet (TCP/IP) to LoRa, model 9743, which can connect LoRa and the Internet.
Shanghai ZLAN LoRa products are high-performance products designed for industrial applications, and their transmission distance can reach 6km~8km in open areas. It adopts 2.4G DSSS spread spectrum technology, which has strong anti-interference ability. Compared with Wifi, its wireless connection distance is longer, the connection speed is faster, the anti-interference ability is strong, and the networking is more convenient.
Features
- Long-distance LoRa communication solution, high performance and high stability. The communication distance is 6km~8km outdoors.
- Support RS485/232/422 interfaces.
- It can be configured as a TCP server, TCP client, UDP, etc.
- Modbus TCP to Modbus RTU mode is supported to collect data.
- The LED indicators indicate the direction of data flow, LoRa communication status, and device operation status respectively, and intuitively reflect the device status
