    I need to broadcast small amounts of data in a radius of about 500 meters to 2 Kms. in real time. Any compatible receiver in the range should be able to receive that data.
    Is there a suitable module for the same? I am considering HC-12 but don't think it can used for broadcasting data to all the surrounding receivers.

    all receivers programmed to the same ID code will receive the signal
    But those units are designed for no license, short range applications 10 metres or so
