is a signal quality tester based on the standard LoRaWAN protocol, equipped with GPS positioning capabilities. It is primarily used to test the LoRa network signal strength at construction sites. It can test the packet loss rate for both uplink and downlink, as well as the Received Signal Strength Indicator (RSSI) and Signal-to-Noise Ratio (SNR), thereby facilitating the analysis and assessment of the LoRa network signal coverage at construction sites

Durable Material: Rust-proof metal or engineering plastics for outdoor durability. Auto-Sensing: Vehicle detection sensors enable automatic lifting/lowering. Anti-Theft: Tamper-proof alarms, reinforced locks, and optional GPS tracking. Power Options: Solar, rechargeable batteries, or wired power supply.

Measures active energy, voltage, current, active power, power factor, and grid frequency (optional: reactive energy and reactive power). Shows active energy consumption with a clear digital screen. Pulse LED: Indicates energy metering pulses. Power LED: Shows power supply status. Supports wired RS485 networks for remote meter reading and centralized management. Compatible with MODBUS-RTU or DLT645 protocols. Configurable with LoRaWAN/NB-IoT/4G/WiFi modules for flexible IoT connectivity.
