IntroductionProject loon is a research and development

project.

Unofficial development on the project began in 2011 under incubation in Google X with a series of trial runs in California’s Central Valley.

The project was officially announced as a Google project on 14 June 2013.

Need of loon :Some population of the world have enjoyed

the benefits of online lifestyles while other majority have not experienced an hour of internet. Places without internet:

AlaskaSahara Desert ArizonaBlack Forest ,Germany

Google Project loonProject Loon is a network of balloons

traveling on the edge of space, designed to connect people in rural and remote areas.

TechnologyProject Loon balloons float in the stratosphere,

twice as high as airplanes and the weather. 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.

The signal bounces from balloon to balloon, then to the global Internet back on Earth.

How loon balloons move?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.

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

StratosphereSituated between 10 km and 60 km altitude

on the edge of space.

Air pressure is 1% of that at sea level.

Thinner atmosphere offers less protection from the UV radiation and temperature caused by the sun’s rays

Parts of loon design

Envelope/BalloonPolyethene material is used for

manufacturing the balloon.These balloons have super pressure design

that can withstand harsh UV radiation and temperature as low as -58F.

The inflated balloon has a dimension of about 50 feet wide and 40 feet tall.

Balloon is filled with helium

Solar PanelEach unit’s electronics are powered by an

array of solar panels that sits between the envelope and the hardware

In full sun, these panels produce 100 Watts of power - enough to keep the unit running while also charging a battery for use at night.

Since the temperature is low and radiation of sun is for fraction of day, it is a challenge for solar power batteries.

EquipmentA small box containing the balloon’s electronic

equipment .

This box contains circuit boards that control the system .

Radio antennas to communicate with other balloons and with Internet antennas on the ground .

And batteries to store solar power so the balloons can operate during the night

This is the first prototype of the of LOON EQUIPMENT. The parachute is stuffed into the hole in the centre (we referred to the design as a "Kleenex box").

How loon connect

AntennaAntenna

AntennaEach balloon is equipped with a GPS for tracking

its location.Three radio transceivers. balloon-to-balloon communications. balloon-to-ground communication. third for backup. The balloons use antennas equipped with

specialized radio frequency technology. Project Loon currently uses ISM bands that are

available for anyone to use.

ISM BandThe industrial, scientific and medical

(ISM) radio bands .

Radio bands reserved internationally for the use of radio frequency (RF) energy for industrial, scientific and medical purposes other than communications.

Cost The cost of a single balloon is not too

high ,Google is planning to fly about 70,000 balloons.

The estimated cost of pilot test in New Zealand for only 30 balloons is about $1.8million

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 Authority from south island .

Google plans on sending up 300 balloons around the world at the 40th parallel south to provide coverage to New Zealand ,Australia and Argentina.

The Nimmo family was the first to connect to balloon-powered Internet

Advantages Easy to use The price of internet will affordableIt will in reach of everyone those who are

beyond geographic reach or can’t afford it.High speedMore number of people will get connect to

online lifestyle.

Disadvantages Cost

Maintenance

Balloon works for few days only

Difficult to collect dropping down balloons

Need of large , clear &safe area for launching of balloon.

CriticismsKenyan tech leaders say the high-flying

Internet balloons may not be a realistic networking solution for their continent.

Bill Gates on Google's Project Loon: 'The actors who just do their core thing are not going to uplift the poor'

ConclusionIndeed in the nearest future, everyone may

eventually have affordable high-speed internet.

Google hopes to have thousands of balloon flying in the stratosphere.
