AN-106 is a signal quality testing instrument based on the standard LoRaWAN wireless communication protocol, with an LCD display screen and automatic network access. Users can use this product to test the uplink and downlink packet loss rates, as well as the RSSI and SNR of the signal. They can also turn on the GPS switch as needed to display the device's latitude and longitude coordinates. AN-106 mainly solves the testing problem of LoRa network on-site construction. Through this equipment, the signal data values of the location can be intuitively tested, achieving professional level signal coverage analysis and evaluation. Widely used in construction sites of all LoRa IoT projects.
