In this paper, the researchers demonstrate the limitations of third party Emergency Alert
Systems (EAS). In particular, because of the architecture of cellular networks, such
systems will not be able to deliver a high volume of emergency messages in a
short period of time. Through discussion, modeling and simulation, this research shows that
current systems not only can not widely disseminate such messages quickly, but
also that the addition traffic created by third party EAS may disrupt other traffic
such as voice communications, including that of emergency responders or the
public to 9-1-1 services.
