Project Loon is a research and development project being developed by Google X with the mission of providing Internet access to rural and remote areas. The project uses high-altitude balloons placed in the stratosphere at an altitude of about 18 km (11 mi) to create an aerial wireless network with up to 4G-LTE speeds.[1][2][3][4] It was named Project Loon, since Google itself found the very idea of providing internet access to the remaining 5 billion population unprecedented and "crazy."[1] The balloons are maneuvered by adjusting their altitude in the stratosphere to float to a wind layer after identifying the wind layer with the desired speed and direction using wind data from the National Oceanic and Atmospheric Administration (NOAA). 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), then onto the global Internet. The system aims to bring Internet access to remote and rural areas poorly served by existing provisions, and to improve communication during natural disasters to affected regions.[5][6] Key people involved in the project include Rich DeVaul, chief technical architect, who is also an expert on wearable technology; Mike Cassidy, a project leader; and Cyrus Behroozi, a networking and telecommunication lead.

3. INTRODUCTION
• Project loon is a research and development project developed
being developed by Google with 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.

4. WHAT IS PROJECT LOON
• Google had considered contracting with or acquiring Space
Data Corp., a company that sends balloons carrying small base
stations about 20 miles up in the air for providing
connectivity.

5. • Unofficial development of the project began in 2011 under
incubation in Google X with a series of trial runs in California’s
central valley. The project was officially announced as Google
Project Loon on June 2013.

6. Pilot Experiment
• On 16th June 2013, Google began a pilot experiment in New
Zealand where about 30 balloons were launched in
coordination with Civil Aviation Authority.

7. 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.

10. User Connectivity
• Users of the service connect to the balloon using a special
Internet antenna attached to their building.
• The sign 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 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 board controls the overall balloon system and radio
antennas are for communication.

14. Envelopes
• Project Loon’s balloon envelopes are made from sheets of
polyethylene plastic and stand fifteen meters wide and twelve
meters tall when fully inflated.

15. Solar panels
• 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.

16. Equipment
• A small box containing the balloon’s electronic equipment.
• This box contains the circuit boards that control the system.
• Radio antennas to communicate with other balloons and with
Internet antennas on the ground.

17. Advantages
• Lower cost
• Availability of information
• Education
• Health and Medicine
• Use of Renewable energy
• Weather surveillance
• Collaboration

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 connectivity by balloon.
• It is still in experimental phase.
