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.
