Project Loon is a Google initiative to provide internet access to rural and remote areas using a network of balloons traveling in the stratosphere. The balloons float 20 km above the Earth's surface 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 special antennas. Each balloon is powered by solar panels and contains equipment like antennas and batteries to communicate with other balloons and transmit internet signals to users below. The goal is to bring internet access to places that lack reliable connectivity.

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

3. 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.

4. History of Project Loon
4
◊ In 2008, Google considered contracting Space Data Corp, but didn't do so.
◊ In 2011, the unofficial development of the project began under Google X
Labs
◊ On 14 June 2013, Google announced this as an official project.
◊ On 16 June 2013, A pilot experiment happened in New Zealand and about
30 balloons were launched.

6. Design Components
 Envelop
 Solar panels
 Equipment Box

7. Envelope
7
 Material : Polyethylene Sheets
 Height : 40 feet
 Width : 50 feet

8. Solar Panel
8
 Each unit’s electronics are powered by an array of solar panels
that sits between the envelope and the hardware.
 In full sun, these panels produce 100 Watts of power - enough
to keep the unit running while also charging a battery for use at
night.
 This way Loon is able to power itself using only renewable
energy sources.

9. Equipments
9
 A box contains circuit boards that control the system .
 Radio antennas to communicate with other balloons and with
Internet antennas on the ground.
 Batteries are used to store solar power so the balloons can
operate during the night.

10. How Loon Moves ?
◊ Project loon balloons travel around 20 km above
the
earth’s surface in the stratosphere.
◊ 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.

11. 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 one has radio antennae that connects
each
loon to other loons.

12. Advantages
◊ Easy to use
◊ Speed comparable to 3G
◊ Use of Renewable Energy

13. 13
Disadvantages
◊ Cost
◊ Maintenance is difficult
◊ Balloon can work for few weeks only

14. Applications
14
 It can improve communication during any disaster to affected
regions.
 Internet will be available at all places, even in Sahara Desert
 It can improve Internet usage in developing countries in region
such as Africa and Southeast Asia that can’t afford
underground fiber cable for providing internet connectivity.

15. Latest Trends
15
 Sri Lanka’s officials signed an agreement with Google to launch
the helium-filled, high-tech balloons over the country, making it
the first country in the world to have universal Internet
coverage.
 Google is gearing up to test 20 high-altitude balloons in north
Australia.

16. Conclusion
In this century, Google's new invention Project Loon provides 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 this facility to overcome the barriers.
Project Loon is still in its development stage. If this is successful, this technology
can replace the currently existing networks.
