Project loon is an ambitious project of Google. Google has worked hard in past few years for development of project loon. The idea is to provide low cost internet to areas which are not connected to internet. This obviously means that america, Europe and other developed countries are not the target. It is designed for countries like sub continent countries and African countries.
The project is based on a balloon which is normally a air balloon contains substation circuitry revolving in an orbit at a particular height. Very large number of these balloons will be connected to each other wirelessly. Forming a ring type structure around earth. A user would be able to connect to internet using these loons. So there is no infrastructure barrier to this. This uses a specific free bandwidth available in space. However some concern over this has been raised by some telecom companies over providing these free bandwidth to Google. it will provide low cost internet to user in ruler areas.

But later on ministry of telecom in a press release declared that Indore a small city in India would be first city in India to get project loon. Google expects it's operation by end of this year.
