Wi-Fi sensing transforms ordinary wireless signals into powerful tools for security monitoring, health tracking, and indoor localization without traditional sensors or cameras.

• Environmental Adaptability: Research addresses how signal variations impact sensing accuracy across different settings
• Cross-Domain Applications: Technology spans security surveillance, medical monitoring, and positioning systems
• Generalization Challenges: Study identifies how surroundings, human positions, and orientations affect signal consistency

For security professionals, this technology enables non-invasive monitoring systems that can detect presence, track movement, and identify activities without privacy-compromising cameras.
