Project Loon aims to provide internet access to the two-thirds of the world's population that lacks it, using balloons launched into the stratosphere. Each balloon can cover an area of about 40 km and connects users to the internet via antennas, bouncing signals between balloons and back to the ground. While it offers advantages like lower costs and renewable energy use, it also faces challenges such as hardware failures and privacy concerns.

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.

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
