I know that LED lights are great. They’re more energy efficient and they’ve saved me a ton of money ever since I replaced my old florescent lights with LED bulbs.
I’ve got an LED TV at home as well and it’s thin, and the colors are just great.
But I never thought that LED lights could do more: like boost WiFi bandwidth by as much as ten times (10x).
Researchers at the Oregon State University have found a way to increase WiFi systems by using LED lights to transmit data. Far out, right?
How were they able to do it? Due to advances in LED technology, it is now possible to modulate LED light faster.
Here’s what it says in an article we found in phys.org:
“Experts say that recent advances in LED technology have made it possible to modulate the LED light more rapidly, opening the possibility of using light for wireless transmission in a “free space” optical communication system.”
This LED-boosted Wi-fi Bandwidth can send data up to 100Mbps per user. Regular Wi-fi systems are capable of those speeds but they have to divide the signal for each user that’s on the network.
This special LED-boosted Wi-fi Bandwidth would mean that each user on the network would get the max speed of the network. Everyone could stream and watch videos without buffering. Or stalling. Or stuttering. Or being in akward positions.
The Oregon State University researchers created a hybrid system that can switch between LED transmitters. This is to extend the Wi-fi signal. And here’s the great thing about it: it can work with exisiting Wi-fi systems.
So can a regular person create this new LED-boosted WiFi Bandwidth device? The answers is no.
Unless you’re a genius. And had easy access to tech. And filthy rich (The last part isn’t true).
If the researchers are right, manufacturers would only need a special photodiode that only costs a dollar each. It could connect either through a USB port or integrated completely in new systems.
We want this one like 5 years ago. Check out the Phys.org article about it here.
