Google Loon is a project that aims to provide internet access to rural and remote areas using balloons floating in the stratosphere. The balloons carry communications equipment that can connect to ground-based antennas, relaying internet signals. They are arranged in a network and steered by winds to desired locations. Each balloon provides connectivity for an area about 40km in diameter. This could help connect people in places that lack traditional internet infrastructure and bring connectivity after disasters. However, challenges include controlling balloon movements, short lifespan, and security/privacy concerns over data.

Google 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

CURRENT SYSTEM
DISADVANTAGES
NOT AVAILABLE EVERYWHERE
COST
SPEED
The population of the world have enjoyed the benefits of resources
provided by internet. The internet is the backbone of the knowledge
of the economy.

CHALLENGES
 Politics.
Balloon control.
Balloon life.
Signal strength.
Wi-Fi connectivity.
Spying and security threat over data.

THE TECHNOLOGY
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.

9. 9
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.

10. 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 users software algorithms to
determine where its balloons need to go, then
moves each one into a layer of a wind blowing in
the right direction .
By moving the wind ,the balloons can be
arranged to form one large communications
network.

HOW LOON IS DESIGNED

13. ENVELOPE
Envelope are made from sheets of polyethylene plastic and
stand fifteen meters wide by twelve meters tall.
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.

15. SOLAR PANELS
Each units electronics are powered by an array of solar
panels that sits between the envelope and hardware.
In full sun panel produce 100watts of power –enough to
keep the unit running while also charging a battery for use
at night.
Project loon is able to power itself using only renewable
energy sources.

17. EQUIPMENT
A small box containing the balloons electronic
equipment.
This box contain current boards that the system.
Radio antennas to communicate with other balloons and
with the internet antennas on the ground.
And batteries to store solar power so the balloons can
operate during night.

18. This is the first prototype of the of LOON EQUIPMENT.
The parachute is stuffed into the hole in the centre (we referred
to the design as a "Kleenex box").

20. HOW LOON CONNECT
Each balloon can provide connectivity to a ground area
about 40km in diameter at speed comparable to 3G.
Three radio transceivers .
 Balloon to balloon communications
 Balloon to ground communication
 Third for backup
The balloons use antennas equipped with specialized radio
frequency technology.

24. DISADVANTAGES
Cost.
Maintenance.
Balloon can work for few weeks only.

CONCLUSION
Wi-Fi encircling entire geographical barrier is always a
boost to the Internet and Project Loon by Google is the
great initiative towards that .With this, almost all people
may get the ability to know the world of internet and
utilize these facility to overcome the barriers

26. 26
FUTURE WORKS
Team Google designing its own IEEE802.11 standards to
develop high speed Wireless internet access as compared
to fiber cable based broadband services and to provide
Wi-Fi connectivity to mobile devices.
