Project Loon is Google's initiative to provide internet access to rural and remote areas using a network of balloons traveling in the stratosphere. The balloons float twice as high as airplanes and are steered by rising and descending to altitudes with winds moving in the desired direction. People on the ground connect to the balloon network using a special antenna. The project aims to give more people access to the internet and possibilities of the online world.

3. 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.

4. 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.

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

12. 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.

13. 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.

14. 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.

18. 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.”
