Survey Paper onGoogle: Project Loon –Balloon For Everyone

Shreya Chakrabarti

How does it work?

Google has taken up this project to provide Internet to the remote areas

The balloons Floating in the stratosphere have reception antennas which receive the signal from the Ground

Balloons form a network within each other and the received signal from the ground is passed on to other balloons

When this signal reaches an area where Internet is required, Balloon provides the signal

Balloon Architecture

Balloon architecture is mainly divided into three parts

The inflated part of the balloon is called a balloon envelope

All the electronics on the balloon are powered by solar panels

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

Balloon Navigation

Project Loon balloons travel approximately 20 km above the Earth’s surface in the stratosphere

Project Loon uses software algorithms to determine where its balloons need to go, then moves each one into a layer of wind blowing in the right direction.

By moving with the wind, the balloons can be arranged to form one large communications network

Where is the Project launched?• 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• Google is in Talks with Telecom Partners in India• In May–June 2014 Google tested its balloon-powered internet access venture in Piauí,

Brazil• Google signed an agreement with officials of Information and Communication

Technology Agency (ICTA) - Sri Lanka, to launch the technology on a mass scale• As a result, by March 2016,Sri Lanka will be the second country in the world to get full

coverage of internet using LTE, after Vatican City• On 29 October 2015, Google agreed to partner with Indonesia's XL Axiata, Indosat and

Telkomsel to bring the technology to the country in the hopes of connecting its 17,000 islands
