Alert system for emergency vehicles using software-defined radio

Abstract

This work is based on the analysis and development of an early alert system for emergency vehicles using Software-Defined Radio (SDR). The system emits radiofrequency signals with frequency modulation over different carriers simultaneously within a delimited range, these signals interfere with the radio receivers of nearby vehicles, alerting other drivers to the presence of the emergency vehicle, thus, allowing them to clear the way which represents a decrease in the time of arrival of the emergency vehicles. In the design phase of this project, an SDR is used to transmit in the frequency range from 88 MHz to 108 MHz and free software platforms (such as GNU Radio and Python) for the development of the communication system and user interface.
