1. PROJECT LOON
Loon for everyone
PRESENTED BY: GUIDED BY:
NEHA CHOUHAN PROF LATA VAISHNAV

ECE,3RD YEAR

3. Introduction
 Project loon is a research and development project.
 Unofficial development on 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 a Google
project on 14 June 2013.

4. Need of loon :
 Some population of the world have enjoyed the
benefits of online lifestyles while other majority have
not experienced an hour of internet. Places without
internet:
 Alaska
 Sahara Desert
 Arizona
 Black Forest ,Germany

5. Google Project loon
 Project Loon is a network of balloons traveling on the
edge of space, designed to connect people in rural and
remote areas.

6. Technology
 Project Loon balloons float in the stratosphere, twice
as high as airplanes and the weather.
 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.
 The signal bounces from balloon to balloon, then to
the global Internet back on Earth.

7. How loon balloons move?
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.
Project Loon 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.
By moving with the wind, the balloons can be arranged to
form one large communications network

8. Stratosphere
 Situated between 10 km and 60 km altitude on the
edge of space.
 Air pressure is 1% of that at sea level.
 Thinner atmosphere offers less protection from the UV
radiation and temperature caused by the sun’s rays

9. Parts of loon design

10. Envelope/Balloon
 Polyethene material is used for manufacturing the
balloon.
 These balloons have super pressure design that can
withstand harsh UV radiation and temperature as low
as -58F.
 The inflated balloon has a dimension of about 50 feet
wide and 40 feet tall.
 Balloon is filled with helium

11. Loon balloon in lab for testing

12. Solar Panel
 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.
 Since the temperature is low and radiation of sun is for
fraction of day, it is a challenge for solar power
batteries.

14. Equipment
 A small box containing the balloon’s electronic
equipment .
 This box contains circuit boards that control the
system .
 Radio antennas to communicate with other balloons
and with Internet antennas on the ground .
 And batteries to store solar power so the balloons
can operate during the night

15. This is the first prototype of the of LOON EQUIPMENT.
The parachute is stuffed into the hole in the centre (we referred to the design as a
"Kleenex box").

18. Antenna
 Each balloon is equipped with a GPS for tracking its
location.
 Three radio transceivers.
 balloon-to-balloon communications.
 balloon-to-ground communication.
 third for backup.
 The balloons use antennas equipped with specialized radio
frequency technology.
 Project Loon currently uses ISM bands that are available for
anyone to use.

19. ISM Band
 The industrial, scientific and medical (ISM) radio
bands .
 Radio bands reserved internationally for the use of
radio frequency (RF) energy for industrial, scientific
and medical purposes other than communications.

20. Cost
 The cost of a single balloon is not too high ,Google is
planning to fly about 70,000 balloons.
 The estimated cost of pilot test in New Zealand for
only 30 balloons is about $1.8million

21. The pilot test
 On 16 June 2013 ,Google began a pilot experiment in
New Zealand where about 30 balloons were launched
in coordination with the Civil Authority from south
island .
 Google plans on sending up 300 balloons around the
world at the 40th parallel south to provide coverage to
New Zealand ,Australia and Argentina.

22. The Nimmo family was the first to connect to balloon-powered Internet

23. Advantages
 Easy to use
 The price of internet will affordable
 It will in reach of everyone those who are beyond
geographic reach or can’t afford it.
 High speed
 More number of people will get connect to online
lifestyle.

24. Disadvantages
 Cost
 Maintenance
 Balloon works for few days only
 Difficult to collect dropping down balloons
 Need of large , clear &safe area for launching of
balloon.

25. Criticisms
 Kenyan tech leaders say the high-flying Internet
balloons may not be a realistic networking solution for
their continent.
 Bill Gates on Google's Project Loon: 'The actors who
just do their core thing are not going to uplift the poor'

26. Conclusion
 Indeed in the nearest future, everyone may
eventually have affordable high-speed internet.
 Google hopes to have thousands of balloon flying in
the stratosphere.
