5. Why Project Loon ?
Many of us think of
the internet as the
global community .
But two_third of the
world ‘ s population
does not yet have the
internet access .

6.  Project Loon start in june
2013.
 30 balloons , launched from
New Zealand’s South Island.
 Pilot testers will be used
to refine the technology.

7. Project Loon balloons float in the stratosphere as 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 balloons to balloons then to the
global internet back on earth.

EQUIPMENT

15. After the Loon is completely
designed it look like this……

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

18.  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.

20.  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.

21. How Does Antenna Receive A Clear Signal?
Polarization means direction of electromagnetic waves are oscillating
with the wind.
To avoid this cross-polorization issue,2 antenna are placed to receive
signals driving in any direction and making their bandwith double.

22. ADVANTAGES
• Lower cost
• Availability of information
• Education and health
• Use of Renewable Energy
• Weather Surveillance

23. DISADVANTAGES
• Hardware Failure
• Internet privacy
• Not a Replacement of Satellite Communication
• Cost
• Maintenance
