1. A computer program product comprising a non-transitory computer-readable medium having computer-readable program code embodied therein related to a broadcast of at least one data packet, the computer program product comprising computer-readable instructions configured to cause a computer system to:

  • receive information of an indication of an event;

    provide a signal for causing a radio to draw power, for a first period of time, at a first level, the first level configured to be below a level that is used to receive at least one data packet;

    cause the radio, at the end of the first period of time, to draw power at a second level, the second level configured to be higher than the first level;

    cause the radio to attempt to receive a set of data following the end of the first period of time and during a second period of time;

    determine whether the set of data corresponds to a first packet, the first packet comprising information associated with a third period of time, the first packet comprising a first chirp packet, wherein the first chirp packet is associated with a first data packet;

    responsive to determining the set of data corresponds to the first packet, identify the third period of time associated with the first data packet;

    responsive to identifying the third period of time, provide a communication for causing the radio to draw power, during the third period of time, at a level below a level that is used to receive at least one data packet; and

    after the third period of time expires, enable the radio to receive the at least one data packet;

    detect receipt of the at least one data packet; and

    upon detecting receipt of the at least one data packet, enable the radio to continue to receive and send data packets for a period of time greater than a time for a back-off period, the back-off period being associated with an amount of time during which the radio does not attempt to transmit a data packet.
