Project Loon is a Google initiative to provide internet access to rural and remote areas using high-altitude balloons. Balloons float in the stratosphere twice as high as airplanes, carried by wind currents. They are equipped with communication antennas to connect to each other and transmit internet signals to antennas on the ground. This allows people's devices to connect and bounce signals between balloons until reaching an internet connection back on Earth. The goal is to use this network of balloons to expand internet access to more of the world's population, especially the estimated 50% without access, primarily in developing areas.

2. What is Project Loon ?
• Project loon is a network of balloons traveling
on the edge of space, designed to connect
people in rural and remote areas.
• It is developed by Google to provide internet
access all over the world.

4. The Technology
• Project loon balloons float in the stratosphere, twice
as high as airplanes and weather.
• They are carried around the Earth by winds and
they can be steered by rising or descending to
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.

5. Design of Loon
• Envelops are made from sheets of polyethylene
plastic, and they measure fifteen meters wide by
twelve meters tall when fully inflated.
• Solar Panels are used to power the equipment's in
the balloon.
• Equipment's -Radio antennas to communicate with
other balloons and with Internet antennas on the
ground. And lithium ion batteries to store solar
power so the balloons can operate throughout the
night.

6. How Loon Connects
• Each balloon can provide connectivity to a ground areas
about 40 km in diameter at speeds comparable to 3G.
• Each balloon is equipped with a GPS for tracking its location.
• Three radio transceivers are:-
-Balloon-to-balloon communications.
-Balloon-to-ground communications.
-Third for back up.
• Project Loon currently uses ISM bands that are available for
anyone to use.

7. Working of Loon

8. Current Progress
• Project Loon began in June 2013 with an
experimental pilot in New Zealand, where a
small group of Project Loon pioneers tested
Loon technology
• The results of the pilot test, as well as
subsequent tests in New Zealand, California’s
Central Valley and in Northeast Brazil, are
being used to improve the technology in
preparation for the next stages of the project.

9. Advantages
• Easy to use.
• Internet Speed is good.
• Increasing the Internet Usage.
• Cost is low compared to satellites.
Disadvantages
• Maintenance is required periodically.
• Balloon can work for few weeks only (100
days).
