Wi-Fi must be getting secure enough if airport security folks are willing to use it: Sprint will be the supplier for Navigance, a company that provides wireless communications and video security monitoring for general aviation (non-commercial) airports. Teterboro airport in New Jersey will get the first installation.
Navigance supplies video cameras, digital video recorders and biometric devices and they're all linked by the WLAN. Sprint is also offering IP transport so the airports can share information with local law enforcement officials.
I guess this means Wi-Fi is doing its part in making it easier for security folks to gather information about us and share it with each other.
