Lifi is the new wifi


The internet has become part of our life today. Everything from shopping, news, entertainment, learning name it all can be accessed online. This brings the need to have high-speed internet. Conventionally light surfing would require mobile data bundles. However with huge downloads and online streaming one opts for a modem or wi-fi.


Forget 4G, 5G, wi-fi,scientists have discovered a new  and the fastest way of connecting to the internet through light. Yes that’s right a light bulb. Li-fi (light fidelity) enables you to access the internet within the illuminated area. Led bulbs are used to transmit data to speeds of 10Gbps done in lab tests.

However commercial li-fi kits have been released having 150Mbps. This opens up possibilities for people who can’t access wi-fi due to signal interference like in submarines and the like. It also means better data security since a wall or anything opaque protects your Li-fi. No more interference by other waves since light is used.

Those who use free wi-fi by the virtue of living near public areas with wi-fi might start rethinking their strategies. Li-fi is here to stay.

Probably scientists would come with a new way to recharge our smart phones on the go. Or better still batteries that can go weeks without recharging. Power banks are becoming bulky or should I say a status statement.

Look out for the next article on a microprocessor that uses wind as its source of power and how to make calls over the wi-fi.
