IntroductionProject Loon is a research and development project being

developed by Google with the mission of providing Internet access to rural and remote areas. 

A balloon is a flexible bag filled with air or gas.The balloon is also considerably used to gather weather

information such as atmospheric pressure, temperature, humidity and wind speed.

It allows people to communicate with others as well.

What is project loonHistory

In 2008, Google had considered contracting with Space Data Corp., a company that sends balloons carrying small base stations about 20 miles (32 km) up in the air in the stratosphere for providing connectivity to truckers and oil companies in the southern United States, but didn't do so.

Continue…On 16 June 2013, Google began a pilot

experiment in New Zealand where about 30 balloons were launched in coordination with the Civil Aviation Authority from the Tekapo area in the South Island.

About 50 local users in and around Christchurch and the Canterbury Region tested connections to the aerial network using special antennas.

Working principle of project Loon

Each super-pressure balloon is massive with a whopping 15-meter diameter.

It is made of very thin, very light polyethylene plastic though, so it lifts up the sky easily.

It is strong enough to lift the flight computer and other electronics. All these are powered by a solar power panel.

The Balloons float in the Stratosphere , twice as high as aeroplanes and weather.

The balloons are maneuvered by adjusting their altitude to float to a wind layer after identifying the wind layer with the desired speed and direction.

User Connectivity

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).

The system aims to improve communication during natural disasters to affected regions. 10/

Technology Used

The small box (payload) hangs below the envelope, and looks very similar to the basket in a hot air balloon.

It holds electronic devices, such as circuit boards, radio antennas, solar panels, batteries, GPS, and devices to monitor weather conditions.

The circuit boards control the overall balloon system and radio antennas are for communications.

AdvantagesWireless connection to the Web, available for free to every person in the world.

Easy to use.Internet access beyond the geographic reach.Project Loon will use a network of balloons to transmit selected internet data – audio, video, text and applications – to any Wi-Fi-enabled device, including mobile phones, anywhere in the world. 15/

DisadvantagesCost was high as we have to take permission, buy antenna and

fix it in home. Maintenance cost will be very high as the total equipment is

very costly and complicated. Balloons must be replaced for every two to three weeks. As

they must be refilled by the gas and should correct the balloon’s equipment if any damages occurs when they are moving at stratosphere.

internet privacy Not a replacement of satellite communication. 16/

conclusionProject Loon is an ambitious project and the world

will highly benefit from it. Project Loon, an initiative to help fill in those

internet gaps through the use of networked balloons.

The goal is to provide broadband-like internet for the two-thirds of the world that doesn’t have access to a reliable internet connection by balloon.
