A device and method for altitude-based interference mitigation in an aerial vehicle. The device includes a transceiver, an altimeter, and an electronic processor coupled to the transceiver and the altimeter. The electronic processor is configured to determine, via the altimeter, an altitude level of the aerial vehicle, compare the altitude level to an altitude threshold, and, in response to the altitude level exceeding the altitude threshold, control a radio frequency characteristic of the transceiver to mitigate signal interference based the altitude level.

Method and device for altitude-based interference mitigation

Methods and systems for providing a time-adaptive notification to public safety personnel when a response to a voice communication including a brevity code is not received. One system includes an electronic computing device configured to monitor a first voice communication received by or transmitted from a first communication device and determine that the first voice communication includes a brevity code having a predetermined meaning. The electronic computing device is further configured to determine a response time based on the predetermined meaning and determine that the response time has elapsed and that a second voice communication has not been transmitted from the first communication device before the response time elapsed. The electronic computing device is further configured to provide a notification on an output device of at least one of the first communication device and a second communication device.
