Answer  Explanation 

ANSWER: Only 1

Explanation:
- Li-Fi, while many magnitudes faster than current Wi-Fi, is limited because it works on light, not radio waves. This means, the information can't travel through walls.
- Li-Fi probably won't completely replace Wi-Fi. It is more likely to work alongside existing technology.
