Depending on what time you're reading this, you may be sitting next to your desk lamp, or underneath your ceiling lights. It's probably not something you give a second thought to after you've flipped the light switch. We are quite used to light illuminating the room, helping us to see; we've had electric light for over a hundred years, so the thought of a lightbulb is probably not very interesting to you.
But it's actually a great time to get excited about light. There have been huge developments in bridging light and high speed mobile communication recently, and connecting your devices to LiFi instead of Wifi is probably not far around the corner.
Special LED lights can be used to send information in the same way that a wireless router sends data through a radio signal. The physics of it is not so different—radio and light are both electromagnetic waves. The main difference is that we can perceive light through our eyes, while radio waves are ignored by our senses.
Soon, though, that floor lamp in the corner of the room might take the place of your wireless router. It is hard to control the range of WiFi, since you can't see it. With LiFi, however, you can see exactly where the coverage is, so it is more secure. Lightbulbs are also everywhere! Think of all the places that use indoor lighting, and you can imagine how ubiquitous LiFi could become.
We at basic6 are very excited about what LiFi can bring to the Internet of Things. Check back often, as we'll be posting about innovative uses of LiFi, and the future of light. And we might have some thrilling LiFi news of our own to share with you soon!
