Base Station | Using the base stations of NB-IoT operator, 50000 meters for one base station | One concentrator can manage 5000pcs water meters, no repeater. | One LoRaWAN gateway can cconnect with 5000pcs water meters, the gateway supports WIFI, Ethernet and 4G. |
Use scenario analysis | It can be used wherever there is NB IoT signal coverage | The equipment is relatively far away, which can control the valve in real time, read data, and set downlink relay | There are no relay and handset devices, relying on LoraWAN network coverage, self built network, and gateway deployment needs to be added |
