2. 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.

4. 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.
30 balloons, launched from New Zealand’s South
Island.
The experience of these pilot testers will be
used to refine the technology and shape the
next phase of Project Loon.

6. THE 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. Stratosphere
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

8. HOW LOON MOVES
Winds in the stratosphere are generally steady and
slow-moving at between 5 and 20 mph, and each layer
of wind varies in direction.
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. ENVELOPE
Project Loon’s balloon envelopes are made from sheets
of polyethylene plastic and stand fifteen meters wide by
twelve meters tall when fully inflated. 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.

13. 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.
By moving with the wind and charging in the sun, Project Loon
is able to power itself using only renewable energy sources.

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. HOW LOON CONNECTS
 Each balloon can provide connectivity to a ground
area about 40 km in diameter at speeds comparable to
3G.
 Each balloon is equipped with a GPS for tracking
its location

16.  Three radio transceivers.
 The balloons use antennas equipped with
specialized radio frequency technology.
 Project Loon currently uses ISM bands that are
available for anyone to use.
balloon-to-balloon communications.
balloon-to-ground communication.
third for backup

18. ISM BANDS
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.

19. Advantages
 Easy to use.
Speed.
 Increasing Internet usage.

20. Disadvantages
 Cost.
 Maintenance.
 Balloon can work for few week
only.
