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
