According to technical fields, the emergency communication systems currently used in the field of public safety mainly include emergency platforms, satellite communication systems, shortwave systems, ultrashortwave systems, communication systems, and remote sensing monitoring systems. A complete emergency communication system should take the emergency platform as the core, and use different interface protocols to integrate satellite communication systems, shortwave systems, ultrashortwave systems, communication systems, and remote sensing monitoring systems into a fully functional system.
The performance requirements of public safety emergency communications: the priority, the stability, and reliability of communications. First, it is necessary to ensure that information exchange can be provided in any environment. Secondly, it is necessary to ensure the smooth exchange of at least one type of information in any extreme environment. Generally, the communication and transmission of voice are guaranteed at the minimum. But high anti-interference ability. For example, several types of communication systems lose base station support, traffic peaks, and strong magnetic interference. The third is the inteligent, digital, and portable performance requirements of terminal equipment. The fourth is big data transmission capability. The fifth is a strong guarantee capability. For example, strong endurance capability, and a variety of guarantees for quick access to electrical energy. Sixth, multi-network integration, and rapid networking capabilities. The public safety emergency communication application environment is harsh and there are many uncontrollable situations. In this case, either a dedicated network is required, or equipment and systems are required to have high-performance interoperability and integration capabilities.
