    LoRa tester AN-106 based on LoRa module. AN-106 LoRa tester is with LCD screen and connects with the gateway via OTAA network joining. It can test the UPLINK and DOWNLINK packet loss rate and meanwhile users can get RSSI and SNR of gateway transmission. Users can also turn on the GPS to display the latitude and longitude coordinates of the device and check the LoRoWAN CLASS type and the firmware version number of the LoRa tester.


    • Supports LoRa wireless communication, supports CN470-510MHz/868MHz/915MHzï¼›

    • Support GPS locating with the accuracy of within 5M;

    • With built-in lithium battery can support the system for 36 hours;

    • With an LCD screen, which can support text interface display;

    • Full plastic shell structure design;

    • Wide working temperature range, to achieve industrial -20℃~+70℃;

    • Support real-time communication with gateway, can get RSSI and SNR of gateway transmission;

    • Support statistics of packet loss rate of communication between gateway and nodes
