3. What is project loon?
Many of us think of the
Internet as a global
community. But two-thirds
of the world’s population
does not yet have Internet
access. Project Loon is a
network of balloons
traveling on the edge of
space, designed to connect
people in rural and remote
areas, help fill coverage
gaps, and bring people
back online after disasters
5. • 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. • Project Loon starts in June 2013 with an
experimental pilot in New Zealand. A small
group of Project Loon pioneers will test the
technology in Christchurch and
Canterbury.
DEVELOPER
• 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.
9. • 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.
12. • The balloon envelope is the name for the inflatable part
of the balloon.
• Project Loon’s balloon envelopes are made from sheets
of polyethylene plastic and stand fifteen meters wide by
twelve meters tall when fully inflated.
• They are specially constructed for use in super pressure
balloons, which are longer-lasting than weather balloons
because they can withstand higher pressure from the air
inside when the balloons reach float altitude.
• A parachute attached to the top of the envelope allows
for a controlled descent and landing whenever a balloon
is ready to be taken out of service.
14. • Each balloon can provide connectivity to a
ground area about 40 km in diameter at
speeds comparable to 3G. For balloon-to-
balloon and balloon-to-ground
communications, the balloons use
antennas equipped with specialized radio
frequency technology. Project Loon
currently uses ISM bands (specifically 2.4
and 5.8 GHz bands) that are available for
anyone to use.
15. Where Loon is going
• The Project Loon pilot test begins June
2013 on the 40th parallel south. Thirty
balloons, launched from New Zealand’s
South Island, will beam Internet to a small
group of pilot testers. The experience of
these pilot testers will be used to refine the
technology and shape the next phase of
Project Loon.
17. 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.
