5. Spread spectrum - Wikipedia

   en.wikipedia.org/wiki/Spread_spectrum

   Spread-spectrum techniques are used for the establishment of secure communications, increasing resistance to natural interference, noise, and jamming, to prevent detection, to limit power flux density (e.g., in satellite downlinks), and to enable multiple-access communications.

6. Radio-frequency identification - Wikipedia

   A visitor entering the museum received an RF tag that could be carried as a card. The eXspot system enabled the visitor to receive information about specific exhibits. Aside from the exhibit information, the visitor could take photographs of themselves at the exhibit. It was also intended to allow the visitor to take data for later analysis.
