For the last few years, we've been hearing about a new technology dubbed "Li-Fi." The idea is that instead of using radio waves to send information like Wi-Fi does, Li-Fi uses light pulses to transmit information. The light pulses are way too fast for the human eye to detect, but electronic gadgets can easily pick them up.

The big advantage of Li-Fi is that it can transmit information up to 200 gigabits per second, where Wi-Fi is barely able to get past 1Gbps. Of course, Wi-Fi is steadily improving, but it still has a ways to go before it hits those speeds. And that isn't Li-Fi's only advantage.

With Li-Fi, it doesn't matter how many gadgets are in range; it could be one or thousands. Wi-Fi is restricted to a few dozen gadgets, meaning when there are hundreds of people in a small area, the network slows to a crawl.

That makes Li-Fi great for office environment, shopping malls, airports, stadiums and other crowded venues. It could also be good in airplanes and buildings that don't play nicely with radio waves. Hospitals are also interested in it, because the radio waves from Wi-Fi can interfere with medical equipment.
