Project Loon is a Google project that aims to provide internet access to rural and remote areas using high-altitude balloons placed in the stratosphere. The balloons create an aerial wireless network with speeds of up to 3G. They are manoeuvred by adjusting their altitude to float on wind currents identified using NOAA wind data. Users connect to the balloon network using a special antenna, and the signal travels between balloons and to ground stations connected to ISPs. If successful, this technology could provide internet access without expensive fiber cable infrastructure.

INTRODUCTION
Project Loon is a research and development projects being developed by Google with the
mission of providing internet access to rural and remote areas. The projects uses high
altitude balloons placed in the stratosphere at to create an aerial wireless network with up to
3G-like speeds.
The balloons are manoeuvred by adjusting their altitude to float to a wind layer after
identifying the wind layer with the desired speed and direction using wind data from the
National Oceanic and Atmospheric Administration (NOAA).
Users of the service connect to the balloon network using a special Internet antenna attached
to their building. The signal travels through the balloon network from balloon to balloon, then
to a ground-based station connected to an Internet service provider (ISP), then onto the
global.
THE TECHNOLOGY
 Project Loon balloons float in the stratosphere, twice as high as airplanes.
 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.
 The set-up 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.
 People connect to the balloon network using a special Internet antenna attached to
their building.
 Solar panels about the size of a card table that are just below the free-flying balloons
generate enough electricity to power the transmitter for a day and beam down the
Internet signal to ground stations.
The technology designed in the projects could allow countries to avoid using expensive fibre
cable that would have to be installed underground to allow users to connect to the Internet.

3. HISTORY
• In 2008, Google considered contracting Space Data Corp, but didn't do so.
• In 2011, the unofficial development of the project began under Google X Labs.
• On 14 June 2013, Google announced this as an official project.
• On 16 June 2013, a pilot experiment happened in New Zealand and about 30 balloons
were launched.
APPLICATIONS
 It can improve communication during any disaster to affected regions.
 It will be available at all places, even in Sahara Desert
 It can improve Internet usage in developing countries in region such as Africa and
Southeast Asia that can’t afford underground fiber cable for providing internet
connectivity.
 It is fast, efficient and more reliable than wired broadband connection
ADVANTAGES
 Easy to use.
 Speed.
 Increasing Internet usage.
DISADVANTAGES
 Cost.
 Maintenance.
 Balloon can work for few weeks only.
LATEST TRENDS
 Sri Lanka will become the first country in the world to have universal Internet
coverage. Sri Lanka’s officials signed an agreement with Google to launch the
helium-filled, high-tech balloons over the country. Google plans to begin releasing the
by March 16.

4.  Google is gearing up to test 20 high-altitude balloons in north-east Australia.
Telstra, Australia’s largest telecommunications company will support the next phase
of the project’s development by supplying base stations to enable communication
with the helium-filled balloons and access to the radio spectrum. Engineers hoping for
a successful test of technology capable of beaming 4G-like signals to receivers on the
ground.
CONCLUSION
In this century, Google's new invention Project Loon provides a very valuable help to poor
people by accessing the internet facility. With this, almost all people may get the ability to
know the world of internet and utilize this facility to overcome the barriers.
Project Loon is still in its development stage. If this is successful, this technology can replace
the currently existing fibre cable network.
