2.2 Product appearance
Third, the general characteristics:
3.1 Wireless parameters
Radio frequency: 470M~480MHZ frequency band;
Transmitting power: 26dBm;
a single LoRa gateway can simultaneously monitor up to 8 channels, collect any terminal data packets conforming to LoRaWAN protocol, and upload to the server through 3/4G or Ethernet. At the same time, it can receive and process the instructions issued by the server, and then send the data packets or perform other actions according to the requirements of the server.
3.2 Environmental conditions
Relative humidity: 5 to 95%, no condensation (at 40 ° C);
Altitude: 0 to 3000 meters;
Environment: no frequency interference, no significant shaking, vibration and impact;
Fourth, mechanical structure requirements
Due to the actual installation and the choice of accessories, there is no uniform size.
4.1 Installation Method
This product is used as the gateway of the LoRaWAN system and can be deployed directly in the area or in the base station.
4.2 SZ10-GW-LoRa equipment is not suitable for installation environment
environment impact on equipment communication
1. When there is too much obstruction between LoRa gateway and LoRa street light controller, or when the obstruction is made of metal, communication signal will be attenuated and affected. Communication distance.
2. When the ambient temperature is below 20 degrees Celsius or above 70 degrees Celsius, the equipment will be faulty when it is struck by lightning.
