Google’s project loon
- 1. Loon Presented By:- Submitted To:- Abhishek Gaurav Mrs. Bhumika Gupta CSE 3rd Year 130202

- 4. Introduction Project 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. Easier for a service provider to recover the equipment cost in areas of high population density
- 5. Why Project Loon Required The main idea behind google loon is to bring internet 2 out of 3 people on the world who don’t have internet access today by using high altitude balloons. 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
- 7. History In 2008, Google considered contracting Space Data Corp, but didn't do so 2011, the unofficial development of the project began under Google X Labs 14 June 2013, Google announced this as an official project 16 June 2013, A pilot experiment happened in New Zealand and about 30 balloons were launched
- 8. 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. People connect to the balloon network using a special Internet antenna attached to their building

- 14. How Loon moves Project loon balloons travel around 20 km above the earth’s surface in the stratosphere. Winds in the stratosphere are generally steady and slow-moving at between 5 and 20 mph, and each layer of wind varies in direction and magnitude. The set-up uses crachy mechanism to determine where its balloons need to go, then moves each one into a layer of wind blowing in the right direction or to change altitude. It uses the data from NOAA(National Oceanic and Atmospheric Administrator) to predict the nature of wind in stratosphere.
- 17. Why Stratosphere ? The stratosphere ranges between 10 km and 60 km altitude on the edge of space. The extreme altitude of the stratosphere presents unique engineering challenges: - Air pressure is 1% of that at sea level - Temperatures hover around -58°F - A thinner atmosphere - Less protection from the UV radiation Suitable because this sphere is having steady stratospheric winds.
- 18. How Loon Connects Each loon has radio antennae that connects each loon to other loon. These antennas are equipped with specialized radio frequency technology with ISM bands of spectrum to achieve high bandwidth of 2.4 GHz to 5.8 GHz. The balloon communicate with specialized internet antennae on the ground. Antennae here points into the sky and talks to the balloon and each of this balloon talks to neighbouring balloon and then back down to ground station which is connected to the internet provider this creates a network in the sky. Two kinds of communications: Balloon-to-Balloon network Balloon-to-Ground station or Subscribers network Can provide connectivity to a ground area about 40 km in diameter. Requires users to install a specialized antenna the outside of their home to receive the signal from a balloon near their home.
- 20. RECEPTION OF LOON SERVICES Reception of Loon services requires a specialized antenna.The special antenna installed the outside of home receives data and decrypt the data. The antennae on balloons are polarized (means direction of electromagnetic waves are oscillating with the wind.) To avoid this cross-polorization issue,2 antenna are placed to receive signals driving in any direction and making their bandwith double. The antenna has to have more sensitive of an angle than it does straight up,so we can get uniform signal strength no matter where the balloons are overhead.
- 24. HOW WILL THE LOON DESCEND? The easiest method to make balloon down to lift the valve at the top to gradually release the helium gas. In the event of an unexpected landing/failure, every Loon balloon is equipped with a parachute to ensure safer landing. Also equipped with special lamps and reflectors to provide warning for aircrafts during the descend. GPS helps to track the descend path of the loon.
- 25. The Pilot Test 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.

Advantage Provide Internet to rural & disaster hit areas Cheaper data rates Cheaper infrastructure Faster & Efficient connection Secure data Education Health and Medicine Use of Renewable Energy Weather Surveillance Requires continuous monitoring Hardware Failure Not a replacement of satellite communication. International politics Disadvantage
- 27. conclusion Project 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. 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 internet and utilize these facility to overcome the barriers.
