More than half of the world's population is still without Internet access.Project Loon is a network of balloons traveling on the edge of space, designed to extend Internet connectivity to people in rural and remote areas worldwide, Where the ground antennaInstallation is very difficult and not affordable

What is a project loon

Equipment :- Envelope(inflatable part

of the balloon) Solar Panels Network Equipment Loon Antenna

Equipment :-

Envelope

The inflatable part of the balloon is called a balloon envelope. A well-made balloon envelope is critical for allowing a balloon to last around 100 days in the stratosphere. Loon’s balloon envelopes are made from sheets of polyethylene plastic, and they measure fifteen meters wide by twelve meters tall when fully inflated. When a balloon is ready to be taken out of service, gas is released from the envelope to bring the balloon down to Earth in a controlled descent. In the unlikely event that a balloon drops too quickly, a parachute attached to the top of the envelope is deployed.

Solar panels

Each balloon’s electronics are powered by an array of solar panels. It uses high efficiency monocrystalline solar cells. The solar array is mounted at a steep angle to effectively capture sunlight on short winter days at higher latitudes. The array is divided into two sections facing in opposite directions, allowing us to capture energy in any orientation as the balloons spin slowly in the wind. The panels produce approximately 600 Watts of power in full sun, which is enough to keep Loon’s electronics running while also charging a battery for use at night. By moving with the wind and charging in the sun, Project Loon is able to power itself using entirely renewable energy sources.

Network Equipment• A small box containing the balloon’s electronics hangs underneath the inflated envelope .• This box contains circuit boards that control the system, 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.• Inside each box is a mini-command centre: radio sensors, satellite receivers, and WiFi electronics, along with a stack of custom Google X circuit-boards. • These computers measure acceleration, take temperature measurements, run communications between satellite and WiFi networks.

Loon antenna

The loon antenna shaped in circular manner marking the symbolism of balloon. They are attached to the households or workplaces wherever the internet connectivity needs to be established.

Working of loon

1.Where loon is situated2.How loon moves3.How loon connects

4.WORKING

Loon balloon float in the stratosphere at 20km altitude.

Stratosphere is the second layer of atmosphere(altitude range 10-50 km) between troposphere and mesosphere.

Where loon situated

Why stratosphereAdvantage of stratosphere:1.the winds here moves steadily and slowly between 5 and 20 mph.2. commercial airliners fly between 9 and 12 km altitude, thus it avoid airplane traffics.3. most weather phenomena occurs in the troposphere. thus they avoid any adverse weather.4.This sphere is great for solar panel, because there is no cloud to block to sun.

How loon moves

Each layer of wind in stratosphere varies in direction. Software algorithms are used to determine where the balloon need to go, then moves it into a layer of wind blowing in the right direction. By moving with the wind ,the balloons can be arranged to form one large communication network.

4.WORKING a user with the specialized antenna sends

signals via a radio frequency over ISM bands to a balloon close to him.

The balloon sends the signals to neighbouring balloons.

Then the signals reach the balloon which is connected to the local Internet .

How loon connects

The local ISP receives the data and forwards them via balloons in the sky to the destination.

Finally , the balloon close to the receiver

broadcasts the data to the grounds via a radio frequency over ISM bands.

It provide ground connectivity to an area about 40 km diameter circle at 3G speed.

The special antenna installed outside home receives data.

Advantages/disadvantages

1.Cheaper internet2.3G speed3.GPS expansion4.exploration

1.Crash incidents2.Costly anteenas3.Looon can last up to 100 days only4.Negotiate with countries to buy radio frequencies

5.Disaster management6.Remote communication7.Launching balloon does not require higher technical skills8.Intelligence gathering9.Satellite recreation10.Scientific data collection11.Wheather surveillance

conclusion

Google's vision for Project Loon procures schooling for those currently without education, brings doctors for people who cannot travel to see one, and provides important weather data to assist farmers, whose harvests are affected by droughts and floods. Illiteracy, Disease and Famine could be dealt a swift and telling blow with a little WiFi and according to Team Loon, balloons stationed so high above the earth they can only be seen with a telescope, is the most affordable and best way to achieve this. "The plastic of the balloons is similar to that in shopping bags and the electronics aren't that different from consumer electronics. This is a very cost-effective way to connect the world. Balloons could become an option for connecting rural, remote, and underserved areas, and for helping with communications after natural disasters.
