New Technology: Radio-Opaque Windows for Enhanced Digital Security

The video discusses the security concerns of wireless networks and introduces a method developed by the University of Warwick to create radio opaque windows. These windows use frequency selective surfaces (FSS) to block specific wireless signals while allowing others, like mobile phone frequencies, to pass through. The technology is tunable, allowing for universal circuitry adaptable to different glass types, making it a versatile solution for changing frequency blocking needs.

What is the primary concern for businesses regarding wireless computer networks?

• A faster internet connection

• A universal remote control

What is the main advantage of the frequency selective surfaces developed by the Warwick team?

• They are more colorful

• They are cheaper to produce

• They are more versatile

• They are easier to install

What is a significant feature of the tunable glass developed by the researchers?

• It is unbreakable
