LiFi – Lights that have Wifi?

Marcus Bronzy is at Mobile World Conference in Barcelona this week and he got to witness something really really cool! Our internet connectivity is about to be revolutionised! With LiFi – a type of technology that will allow internet connections via light. Yes light. It’s quicker than wifi too! When we said Lights we mean any lights, so thats lights that are in our car headlights, street lights and the lights in our homes.

LiFi: How does it work?

LiFi enabled LED lights modulate illumination levels and send data, just like morse code. Thus sending it to your device. The current (light) can be modulated at extremely high speeds, this in turn can be detected by a light detector on your device and the current re-converted into an electrical current, therefore carrying data.

You will still need an ethernet connection to connect to the internet, but once you’re all set up, you’re good to go to get wireless internet from light!

As routers are that gives you 100mbs a second, lights are much faster as each LED bulb has a maximum of 42mbs EACH. So if you have 10 LED bulbs in your area, that’s a total of 400mbs! What makes it faster is that data is sent and received at the same time!

LiFi doesn’t use radio frequencies, it uses the light spectrum which allows for a whole lot more data to be carried. 1000x more bandwidth available to users to be exact!It doesn’t affect radio frequencies either so you can use it in hospitals, airplanes and places like chemical plants. Safely.

This technology will be an integral part of wireless networks in the future!

LiFi: Security

LiFi is limited to the area in which the light illuminates and touches. So unlike WiFi your signal will remain hidden to anyone outside of the illuminated area! Want even more security? Simply close the door or draw the curtains to protect your network from hackers! The LiFi lights are fully networked and each light can ‘speak’ to each other, each with their own separate IP address! Why would the lights need to speak to one another? So you’re able to move around your home or office space and not lose connection!
