Let's break down the working principle of a LoRaWAN energy meter and a LoRaWAN gateway:
1. LoRaWAN Energy Meter:
Measurement: The energy meter measures electrical parameters (voltage, current, power, energy) using internal sensors. These measurements are converted into digital data. Data Processing: The meter's microcontroller processes the measurement data and formats it according to the LoRaWAN protocol.
LoRaWAN Transmission: The meter's LoRaWAN module transmits the data wirelessly using the LoRa radio modulation technique. LoRa modulation allows for long-range communication with low power consumptionThe meter transmits data on specific frequency channels and spreading factors, as defined by the LoRaWAN network.
Prepaid Functionality (if applicable): If it's a prepaid meter, it will also contain logic to check the remaining credit. If the credit is low, the meter can send alerts or disconnect the power via an internal relay.
Security: LoRaWAN employs end-to-end encryption to secure the data transmission.
2. LoRaWAN Gateway:
LoRa Reception: The LoRaWAN gateway acts as a bridge between the LoRaWAN end devices (like the energy meter) and the network server. It receives LoRa radio signals from the energy meter on multiple frequency channels simultaneously.
Data Forwarding: The gateway forwards the received data packets to the network server using a backhaul connection (e.g., Ethernet, Wi-Fi, cellular). The gateway does not decrypt or interpret the data; it simply forwards it.
Network Server Communication: The gateway communicates with the network server using an IP-based protocol.
