b. Invisible Light Communication
c. Infrared Communication
d. None of the above
ANSWER: Visible Light Communication
Scientists have developed a new material that provides efficient lighting and powers wireless internet with data speed of 2 GB per second
- Researchers from King Abdullah University of Science and Technology in Saudi Arabia developed the new nano crystalline material that makes white light out of blue light.
- WiFi and Bluetooth are now week established technologies, but this VLC or visible light communication technology makes use of parts of the electromagnetic spectrum that are unregulated and potentially more energy efficient.
- VLC also combines information transmission with illumination and display technologies.
- Researchers created nanocrystals of cesium lead bromide roughly 8 nanometers in size using simple, cost effective solution based method that incorporated conventional nitride phosphor.
- The scientists have also found a way to make transparent transistors and other essential components of electronic circuitry.
- Indium tin oxide is the current material of choice for electronics as it combined optical transparency with electrical conductivity
- Low cost alternative is transparent material Aluminium doped zinc oxide used for making transparent electrical circuitry..
