Emergency communication system based on broadband wireless theory: A review

With the development of the international political and military situation and the continuous deepening of national reform and opening up, the collision of social interests has become increasingly complex, the frequency of emergencies has increased, the impact and spread have become more and more widespread, and the possibility of large-scale conflicts has also increased. The bigger it is, it highlights the importance of rapid on-site handling and control of emergencies. In order to better maintain the development of China’s social and economic construction and improve the efficiency of emergency response in the new era, it is urgent to accelerate the transformation of the emergency response team’s combat effectiveness generation mode, and put forward new requirements for emergency communications at the emergency site. The main part of this paper has been implemented in actual equipment, and the key algorithms have been verified by the real environment, which has a positive reference for the formulation of the national emergency communication guarantee system. This paper studies and discusses the key technologies of broadband wireless emergency communication, and for the mobile organization and rapid deployment of emergency communication systems on the scene of emergencies, a set of broadband wireless emergency communication system structure oriented to the scene of emergencies is constructed. Then, we conducted in-depth research on the communication reliability and effectiveness of the new architecture in the complex electromagnetic environment of the emergency site.
