- WiFi transmits data with the help of WiFi router using radio waves whereas Lifi transmits data with the help of LED bulbs using light. LiFi has less interference issues as compare to WiFi.
- Wi-Fi works by spewing out radio waves in all directions. Li-Fi does the same thing by flickering out light from a bulb.
- Almost everyone uses Wi-Fi every day and Bluetooth every so often. But these wireless technologies have a fatal flaw: they use radio waves to communicate. The problem with radio waves is that, although they offer decent speeds, they transmit data slowly, and the signal is often blocked or affected by equipment as simple as the microwave in your kitchen. However, a team of scientists are hard at work developing a new, extremely fast method of wireless communication, and it doesn’t use radio waves; it uses light from LED bulbs.
- Light-based wireless communication, coined as Li-Fi by Harald Haas at a TED talk in 2011, is a method of internet connectivity that doesn’t use cables or radio waves, instead flickering the light from a special LED to transmit data just like your Wi-Fi adapter would. The technology is still being developed by researchers at the University of Edinburgh in the UK, but it already looks like it will be more effective and more secure than traditional radio-based communication.
- Li-Fi can only work when your device can detect the light being emitted by the Li-Fi router, meaning it will only work if you’re in the same room or area the light is being emitted. This means people passing by cannot connect and piggyback off of your Internet connection. And did we mention that it’s unaffected by RF-emitting equipment operating in the same room, such as a microwave or radio.
