How it works
To operate, cellular networks need base stations. These stations are positioned close to a sensor network (made up of 100–1,000 separate units). For instance, the gateway is placed adjacent to homes that have radio modules for utilities like power, gas, and water. The radio modules capture meter data, which is then sent to the hub through the LoRaWAN network. The data is subsequently forwarded via the gateway to a server for evaluation. The gateway uses LAN or Wi-Fi networks to access high-speed data lines for this reason.
