Physical-Layer Wireless Confinement

Physical-layer wireless confinement technology uses electric field (E-field) communication to create ultra-secure, short-range data links that are physically impossible to intercept beyond a 10cm radius. Unlike traditional radio frequency signals that propagate through space and can be intercepted from meters away, E-field signals are confined to an extremely small "bubble" around the transmitter and receiver, providing privacy-by-physics rather than encryption-by-software.

The technology enables secure device pairing, access control, and data transfer in zero-trust environments where traditional wireless security measures are insufficient. Applications include secure payment terminals, medical device communication, government and military systems, and any scenario requiring guaranteed signal containment. The physical limitation means that even sophisticated attackers cannot intercept signals without being physically within centimeters of the devices, making it ideal for high-security environments.
