This presentation examines how Wi-Fi technology is used in warfare for surveillance, movement tracking, and intelligence gathering. It covers how Wi-Fi signals can detect crowd sizes, monitor people inside buildings, and track individual movements through device fingerprinting. Real-time data analysis, supported by AI, enables quick military decisions. Ethical concerns, countermeasures like jamming, and future trends in Wi-Fi surveillance technologies like 5G and AI-driven analytics are also discussed. The presentation underscores Wi-Fi’s growing role in modern warfare and the balance between security and privacy.
