Emergency Communication Technology and Systems is a comprehensive technical guide to the principles, standards, and engineering practice behind modern emergency communication.
When disaster strikes, conventional communication networks are often the first casualty — power fails, infrastructure is damaged, and normal channels go silent exactly when they're needed most. This book systematically covers the technologies designed to keep critical information flowing under the worst possible conditions: satellite communication, HF/shortwave systems, digital trunking, public mobile network emergency support, ad hoc networking, space-air-ground integration, wireless through-the-earth communication, and multi-network convergence.
Beyond the core technology chapters, the book examines how emergency communication systems are architected — from requirements analysis through layered system design — and looks ahead to how emerging technologies like integrated sensing and communication, large language models, network digital twins, reconfigurable intelligent surfaces, terahertz communication, and semantic communication are beginning to reshape the field.
Each chapter combines underlying physical and protocol-level principles with the relevant international standards (ITU-R, ITU-T, 3GPP, IETF, ETSI, ATIS) and real engineering constraints, making the book equally useful as a reference for practicing engineers and as a teaching text for graduate and upper-level undergraduate courses in communication engineering and emergency management.
