In today's world it is very important for people to have access to the Internet. Unfortunately today 2/3rd of the world or more than 4 billion people don't have access to Internet. A major portion of the population of the developing world does not have access to the Internet. Even people living in many cities of the developing world don't have access to the Internet, the reason is that they can't afford to have a connection.
Internet should be considered a basic human right and it should be provided freely by the governments. As we all know that Google Loons will soon launch its loons Internet project in Indonesia and Sri Lanka. Google Loons has improved its processes and technology since it first started, the speed has also gone up to 4G levels of 10 Mbps.
Another way of providing cheap Internet service to the people is by using light itself. We already have the Li-Fi technology to transmit wireless data by simply using an LED light. But this idea is no expanded over a wide area. In the below video it is shown how data can be sent by using an off the shelf LED lamp and an off the shelf small solar panel.
The solar panel itself acts as the receiver of data. The Light from the LED lamp lead to a generation of current in the circuit made with the solar panel. As we know digital data is all about 0s and 1s, so there would be a constant variance in the intensity of light, which would result in variance in the voltage of the solar panel circuit. This lower and higher data would encode for 0 and 1 respectively.
The change in the intensity of light would vary depending on the input data. This change would be very very fast for the human eye to realize. Speeds up to 50 Mbps have been already achieved. In the very near future, using this technology, LED streetlights can be used to transmit free wireless Internet data.
In this TED video, a particle demonstration of this technology has been shown with a live demonstration to the audience. This light based wireless Internet system would considerably reduce the cost of Internet access. Thus it would make it possible for governments to provide unlimited and fast Internet across to all their citizens.
Access to Internet will change lives of billions of people across the world and researchers are constantly working on technologies that make Internet access cheaper, faster and better.
