Project Loon is a network of balloons traveling in the stratosphere designed to provide internet connectivity to rural and remote areas. The project was announced by Google in 2013 and began experimental pilots over New Zealand. Balloons float 20 km above the Earth, using solar power and steering with wind currents to remain in position and form a communications network. Each balloon can provide internet to an area with a 40 km diameter. The goal is to make internet access affordable, easy and fast for people around the world.

2.  Project Loon is a network of balloons
traveling on the edge of space, designed
to connect people in rural and remote
areas.

3.  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.
 On 16 June 2013, Google began a pilot
experiment in New Zealand.

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.

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.

6.  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.  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.

10.  ENVELOPE
 SOLAR PANELS
 EQUIPMENT

11.  Envelop
 Solar panels
 Equipment

12.  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.  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.  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.  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.
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.  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.  Easy to use.
 Speed.
 Increasing Internet usage.

21.  Cost.
 Maintenance.
 Balloon can work for few week only.
