What is Google Project loon? Project Loon is a research and development project being developed by Google X with the mission of providing Internet access to rural and remote areas. The project uses high-altitude balloons placed in the stratosphere at an altitude of about 20 mi (32 km) to create an aerial wireless network with up to 3G-likespeeds. Because of the project's seemingly outlandish mission goals, Google dubbed it "Project Loon".

Introduction The Internet is one of the most transformative technologies of our lifetimes. But for 2 out of every 3 people on earth, a fast, affordable Internet connection is still out of reach. And this is far from being a solved problem. There are many terrestrial challenges to Internet connectivity—jungles, archipelagos, mountains. There are also major cost challenges. Right now, for example, in most of the countries in the southern hemisphere, the cost of an Internet connection is more than a month’s income. Solving these problems isn’t simply a question of time: it requires looking at the problem of access from new angles. So today we’re unveiling our latest moonshot from Google[x]: balloon- powered Internet access.

How it works? A Loon is a helium-filled mylar balloon floating about 20 km (12 mi) above the Earth’s surface, carrying an internet router and associated gear. Project Loon works on open Atmosphere in Stratosphere using Solar energy and Wind energy. To connect to the Google Balloon network, the client require a special internet antenna at ground. A Google Balloon can cover an area of 100s of square kilometers.

Navigation with the Wind

Stratosphere Stratosphere is situated on the edge of space, between 10 km and 60 km in altitude having steady winds below 20 mph. In the stratosphere, there are many layers of wind, and each layer of wind varies in direction and speed. Loon balloons are directed by rising or descending into a layer of wind blowing in the desired direction of travel by using wind data from NOAA.

Design Components Envelope Solar Panel Electronics Each balloon’s solar panel provides power to its own electronics. It uses high efficiency monocrystalline solar cells. mounted at a steep angle,produces 100 Watts of sun(approx.) Electronic Box (circuit boards, Linux-based computer, radio antenna, GPS, sensors, and batteries.) The balloon envelope is the name for the inflatable part of the balloon.

How loon connects? Each balloon can provide connectivity to a ground area. To use LTE, Project Loon partners with telecommunications companies to share cellular spectrum. Balloons relay wireless traffic from cell phones and other devices back to the global Internet using high-speed links.

Where does loon travel? Project Loon began with a pilot test in June 2013, when thirty balloons were launched from New Zealand’s South Island and beamed Internet to a small group of pilot testers. The pilot test has since expanded to include a greater number of people over a wider area. Looking ahead, Project Loon will continue to expand the pilot, with the goal of establishing a ring of uninterrupted connectivity at latitudes in the Southern Hemisphere, so that pilot testers in these latitudes can receive continuous service via balloon-powered Internet.

Pros and Cons Cons: Pros: Easy to use Speed Cost Increasing Internet Usage Cost Maintenance

Conclusion In this century, Google’s new invention Google project loon provide 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 interest and utilize these facility to overcome the barriers.
