What is Project Loon ?
◊ Project Loon is a network of balloons travelling on the edge of space, designed to connect people in rural and remote areas.
◊ It is an initiative taken by Google to provide internet access all over the world.

The Technology
◊ Project Loon balloons float in the stratosphere, twice as high as airplanes.
◊ They are carried around the Earth by winds and they can be steered by rising or descending to an altitude with winds moving in the desired direction.
◊ People connect to the balloon network using a special Internet antenna attached to their building.
Google's Project loon 5
◊ In 2008, Google considered contracting Space Data Corp, but didn't do so
◊ 2011, the unofficial development of the project began under Google X Labs
◊ 14 June 2013, Google announced this as an official project
◊ 16 June 2013, A pilot experiment happened in New Zealand and about 30 balloons were launched

How Loon Moves ?
◊ Project loon balloons travel around 20 km above the earth’s surface in the stratosphere. ◊ Winds in the stratosphere are generally steady and slow- moving at between 5 and 20 mph, and each layer of wind varies in direction and magnitude. ◊ The set-up uses software algorithms to determine where its balloons need to go, then moves each one into a layer of wind blowing in the right direction.

Why Stratosphere ?
◊ The stratosphere ranges between 10 km and 60 km altitude
on the edge of space.
◊ The extreme altitude of the stratosphere presents unique
engineering challenges:
- Air pressure is 1% of that at sea level
- Temperatures hover around -50°c - A thinner atmosphere - Less protection from the UV radiation
◊ Suitable because this sphere is having steady stratospheric winds.

How Loon Connects ?
◊ Each loon has an antenna that provides connectivity to the ground. There is a special antenna that is installed on the ground to access the Internet from the loon.
◊ Each has radio antennae that connects each loon to other loons. These antennas are equipped with specialized radio frequency technology with ISM bands of spectrum 2.4 GHz to 5.8 GHz.

Conclusion
◊ In this century, Google's new invention Google project loon provide a very valuable help to poor people by accessing the internet facility. With this, almost all people may get the ability to know the world of internet and utilize these facility to overcome the barriers.
“Give a child a balloon and maybe they'll smile for a day. Give them one with Wi-Fi and the possibilities, Google hopes, are limitless.”
