Application of multi-domain broadband self organizing network based on wireless mesh network in emergency communication

摘要

In view of the problems and shortcomings of the existing emergency communication system, such as insufficient communication capacity, insufficient automation of deployment and integration of various communication modes, in order to better meet the requirements of communication service support under emergency conditions, wireless mesh network technology is analyzed and introduced. Combined with the rapid development of wireless transmission, spectrum sensing, heterogeneous network convergence and gradient routing technology in recent years, the architecture of multi domain broadband self organizing network is proposed, the key technologies involved are analyzed, and the typical application scenarios of the system are given. Through the actual measurement, it is verified that the scheme can be well applied to emergency communication support under emergency conditions.
