    Hello experts,

    I see that ELB-REV4 has multiple wireless communications
    • LTE modem
    • Wifi
    • LoRA (sx1276)
    • Bluetooth
    we want to use LoRA as a main source of communication for our projects.
    my questions
    Does this LoRa module of +14dBm signal unit. travel to large distance like 3 km or so

    our goal is to achieve communication between 2 nodes with a distance of 3 km minimum

    Regards

    +14dBm signal is more than enough for communicating between two devices at a distance of 3km range. the other wireless communication like LTE modem or wifi or ethernet as used to transmit your data over the internet so you can remotely control end LoRa clients. off course you can achieve the communication between 2 nodes with a distance of 3km easily.

    Regards

    a tad doubtful with that response it's only around 25 - 30mW

    There would have to be good high gain antennas at each end and clear line of sight between antennas, no trees, buildings etc
    and it may happen depending on coax used and lengths of coax at each end between transceivers and antennas
