1. A system comprising:
a radio frequency (RF) receiver to receive a radio signal from a remote source;
a signal augmentation agent coupled with the RF receiver to modify signal phase information in the received radio signal based on one or more emergency parameters to generate a modified signal in response to a detection of an emergency condition; and
a radio frequency (RF) transmitter coupled with the signal augmentation agent to transmit the modified signal, wherein the modified signal is indicative of the emergency condition.
