5G, the emerging technology in mobile communication, is expected to deliver an important and decisive impact on several of the UN's Sustainable Development Goals where universal accessibility to ICTs remains a serious concern. However, cyber security has emerged as a serious challenge, not least because of the increased accessibility and broader usage with associated vulnerability. Developing countries have additional challenges associated with both the expected faster build-up of accessibility and lack of qualified competencies within cyber security. Discussion of these challenges is the overall theme and motivation for this book.

Technical topics discussed in the book include:

• 5G in rural networks
• Critical infrastructures
• Open RAN
• Protection of privacy
• Cybersecurity and machine learning
• Cybersecurity and disaster monitoring
