When earthquakes, floods, or mine disasters sever every conventional link, how do rescuers stay connected? This book maps the full engineering landscape of emergency communication — satellite, HF, digital trunking, ad hoc networks, space-air-ground integration, and through-the-earth systems — then looks ahead to AI, integrated sensing, and 6G. Essential reading for communication engineers.

Erlang was created to build systems that never stop. From its origins in telecommunications to modern platforms like WhatsApp and RabbitMQ, its approach to concurrency and fault tolerance has shaped some of the world's most reliable software. This book teaches both the language and the principles behind building resilient, production-ready systems.

Stop memorizing networking concepts—start understanding how real networks work. This book takes you from network architecture and TCP/IP fundamentals to routing, switching, wireless security, common cyber attacks, and defense-in-depth strategies. Perfect for students, IT professionals, and anyone beginning a career in cybersecurity.

5G isn't just faster 4G — it's a full redesign of how mobile networks work. Written by a telecom CEO with 35+ years' global experience, this book connects the entire 5G stack — spectrum, RAN, core, security, charging, regulation — into one narrative. The helicopter view every 5G professional needs.
