LoRaWAN Signal Tester

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
