Project Loon is a Google project that aims to provide internet access to rural and remote areas using high-altitude balloons. The balloons float in the stratosphere twice as high as airplanes, acting as floating cell towers. Each balloon is equipped with a solar panel and electronics to power a wireless connection. The balloons are maneuvered by adjusting their altitude to ride wind currents, forming a network that beams the internet signal from balloon to balloon. The goal is to deliver broadband-like internet to people worldwide who currently lack reliable access.

3. Introduction
 Project Loon is a research and development project being developed
by Google with the mission of providing Internet access to rural and
remote areas.
 A balloon is a flexible bag filled with air or gas.
 The balloon is also considerably used to gather weather information
such as atmospheric pressure, temperature, humidity and wind speed.
 It allows people to communicate with others as well.

4. What is project loon
History
In 2008, Google had considered contracting
with Space Data Corp., a company that sends
balloons carrying small base stations about 20 miles
(32 km) up in the air in the stratosphere for providing
connectivity to truckers and oil companies in the
southern United States, but didn't do so.

 On 16 June 2013, Google began a pilot
experiment in New Zealand where about 30
balloons were launched in coordination with
the Civil Aviation Authority from the Tekapo
area in the South Island.
 About 50 local users in and
around Christchurch and the Canterbury
Region tested connections to the aerial network
using special antennas.

6. Working principle of project Loon
 Each super-pressure balloon is massive with a whopping 15-meter
diameter.
 It is made of very thin, very light polyethylene plastic though, so it lifts
up the sky easily.
 It is strong enough to lift the flight computer and other electronics. All
these are powered by a solar power panel.
 The Balloons float in the Stratosphere , twice as high as aeroplanes and
weather.

The balloons are maneuvered by
adjusting their altitude to float to a wind
layer after identifying the wind layer
with the desired speed and direction.

10. User Connectivity
 Users of the service connect to the balloon network using a
special Internet antenna attached to their building.
 The signal travels through the balloon network from balloon
to balloon, then to a ground-based station connected to
an Internet service provider (ISP).
 The system aims to improve communication during natural
disasters to affected regions.

12. Technology Used
 The small box (payload) hangs below the envelope, and
looks very similar to the basket in a hot air balloon.
 It holds electronic devices, such as circuit boards, radio
antennas, solar panels, batteries, GPS, and devices to
monitor weather conditions.
 The circuit boards control the overall balloon system
and radio antennas are for communications.

15. Advantages
 Wireless connection to the Web, available for free to every person in
the world.
 Easy to use.
 Internet access beyond the geographic reach.
 Project Loon will use a network of balloons to transmit selected
internet data – audio, video, text and applications – to any Wi-Fi-
enabled device, including mobile phones, anywhere in the world.

16. Disadvantages
 Cost was high as we have to take permission, buy antenna and fix it in
home.
 Maintenance cost will be very high as the total equipment is very costly
and complicated.
 Balloons must be replaced for every two to three weeks. As they must be
refilled by the gas and should correct the balloon’s equipment if any
damages occurs when they are moving at stratosphere.
 internet privacy
 Not a replacement of satellite communication.

17. Applications
 Education
 Health and Medicine
 Weather Surveillance
 Collaboration to work together in various Business fields.

18. conclusion
 Project Loon is an ambitious project and the world will
highly benefit from it.
 Project Loon, an initiative to help fill in those internet gaps
through the use of networked balloons.
 The goal is to provide broadband-like internet for the two-
thirds of the world that doesn’t have access to a reliable
internet connection by balloon.
