Realization of Wireless Broadband Emergency Communication System Based on TDMA

This article mainly introduces the realization method of the private broadband wireless emergency communication system based on TDMA. It compares the characteristics of the wireless emergency communication system via private network and public network, and points out the advantages of the TDMA based broadband wireless emergency communication system. It describes the framework of the TDMA based broadband wireless emergency communication system from the networking structure and wireless interface aspects. It also proposes the realization method of the TDMA based broadband wireless emergency communication system in terms of access methods, frame synchronization, modulation and coding technology, QoS technology and anti-interference technology. This private network as a new generation of emergency communication system has features such as rapid deployment, strong scalability, bandwidth allocation flexibility, high security, anti-interference ability and so on.
