As two-thirds of the world’s population does not yet have internet access, “Google’s Project Loon” – a network of balloons travelling on the edge of space – is designed to connect people in rural and remote areas, helping fill coverage gaps, and bringing people back online after natural disasters. Floating high in the stratosphere – twice as high as airplanes and the weather – the ‘Project loon balloons’ 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 network using a special internet antenna attached to their building. The signal bounces from balloon to balloon, which then provides a connection back down on earth. Each miniature blimp can provide connectivity to a ground area about 40 km in diameter at speeds comparable to 3G. For balloon-to-balloon and balloon-to-ground communications, the infrastructure use antennas equipped with specialized radio frequency technology. As part of the 2013 test pilot in New Zealand, project loon used ISM bands (specifically 2.4 and 5.8 GHZ bands) that are available for anyone to use. Tracking the latest research activity carried out, one of helium laden balloon of project loon went around the world in just 22 days, which was originally expected to be done in a span of 33 days.

Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas. The balloon is also considerably used to gather weather information such as atmospheric pressure, temperature, humidity and wind speed.
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 18 km (11 mi) to create an aerial wireless network with up to 4G-LTE speeds. It was named Project Loon, since Google itself found the very idea of providing internet access to the remaining 5 billion population unprecedented and "crazy."
A Survey on Google Project Loon Google Balloonijtsrd
Now a days most people are on the internet, we can say that internet is one of the important aspects in everyone's life. But many live in areas where the infrastructure of internet has not yet reached. If you are in such areas and you need to use your phone's internet, where can you receive internet when you stuck into these areas Simple, connect to the internet that is provided by balloon above you. Google may initially partner with BSNL for testing this technology by use broadband spectrum in 2.6 GHZ band. When contract, a Google spokesperson refused to comment. The technology used for 4G service, has potential to replace mobile towers as it can directly transmit signals on 4G mobile phones. The project name Project Loon was appropriately chosen because it partially involves balloons and partially because it sounds looney.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

PROJECT LOON

CHAPTER 1
1.1 INTRODUCTION
In 2008, Google had considered contracting with or acquiring Space Data Corp.,
a company that sends balloons carrying small base stations about 20 miles (32 km) up in the
air for providing connectivity to truckers and oil companies in the southern United States, but
didn't do so. 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.
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. After this initial trial,
Google plans on sending up 300 balloons around the world at the 40th parallel south that
would provide coverage to New Zealand, Australia, Chile, and Argentina. Google hopes to
eventually have thousands of balloons flying in the stratosphere.
The technology designed in the project could allow countries to avoid using
expensive fibre cable that would have to be installed underground to allow users to connect to
the Internet. Google feels this will greatly increase Internet usage in developing countries in
regions such as Africa and Southeast Asia that can't afford to lay underground fibre cable.
The high-altitude polyethylene balloons fly around the world on the prevailing winds (mostly
in a direction parallel with lines of latitude, i.e. east or west). Solar panels about the size of a
card table that are just below the free-flying balloons generate enough electricity in four
hours to power the transmitter for a day and beam down the Internet signal to ground stations.
These ground stations are spaced about 100 km (62 mi) apart, or two balloon hops, and
bounce the signal to other relay balloons that send the signal back down.
This makes Internet access available to anyone in the world who has a receiver
and is within range of a balloon. Currently, the balloons communicate using unlicensed 2.4
and 5.8 GHz ISM bands, and Google claims that the setup allows it to deliver "speeds
comparable to 3G" to users. It is unclear how technologies that rely on short communications
times (low latency pings), such as VoIP, might need to be modified to work in an
environment similar to mobile phones where the signal may have to relay through multiple
balloons before reaching the wider Internet.
The first person to connect to the "Google Balloon Internet" after the initial test
balloons were launched into the stratosphere was a farmer in the town of Leeston, New
Zealand, who was one of 50 people in the area around Christchurch who agreed to be a pilot
tester for Project Loon. The New Zealand farmer lived in a rural location that couldn't get
broadband access to the Internet, and had used a satellite Internet service in 2009, but found
that he sometimes had to pay over $1000 per month for the service. The locals knew nothing
about the secret project other than its ability to deliver Internet connectivity; but allowed
project workers to attach a basketball-sized receiver resembling a giant bright-red party
balloon to an outside wall of their property in order to connect to the network.

1.2 HISTORY OF INTERNET:
The history of the Internet begins with the development of electronic
computers in the 1950s. Initial concepts of packet networking originated in several
computer science laboratories in the United States, Great Britain, and France. The US
Department of Defence awarded contracts as early as the 1960s for packet network
systems, including the development of the ARPANET (which would become the first
network to use the Internet Protocol.) The first message was sent over the ARPANET
from computer science Professor Leonard Kleinrock's laboratory at University of
California, Los Angeles (UCLA) to the second network node at Stanford Research
Institute (SRI).
Packet switching networks such as ARPANET, Mark I at NPL in the
UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late
1960s and early 1970s using a variety of communications protocols. The ARPANET in
particular led to the development of protocols for internetworking, in which multiple
separate networks could be joined into a network of networks.
Access to the ARPANET was expanded in 1981 when the National Science
Foundation (NSF) funded the Computer Science Network(CSNET). In 1982,
the Internet protocol suite (TCP/IP) was introduced as the standard networking
protocol on the ARPANET. In the early 1980s the NSF funded the establishment for
national supercomputing centres at several universities, and provided interconnectivity
in 1986 with the NSFNET project, which also created network access to
the supercomputer sites in the United States from research and education organizations.
Commercial Internet service providers (ISPs) began to emerge in the late 1980s. The
ARPANET was decommissioned in 1990. Private connections to the Internet by
commercial entities became widespread quickly, and the NSFNET was decommissioned
in 1995, removing the last restrictions on the use of the Internet to carry commercial
traffic.
Since the mid-1990s, the Internet has had a revolutionary impact on culture
and commerce, including the rise of near-instant communication by electronic
mail, instant messaging, voice over Internet Protocol (VoIP) telephone calls, two-way
interactive video calls, and the World Wide Web with its discussion
forums, blogs, social networking, and online shopping sites. The research and education
community continues to develop and use advanced networks such as NSF's very high
speed Backbone Network Service(vBNS), Internet2, and National Lambda Rail.
Increasing amounts of data are transmitted at higher and higher speeds over fibre optic
networks operating at 1-Gbit/s, 10-Gbit/s, or more. The Internet's takeover of the global
communication landscape was almost instant in historical terms: it only communicated
1% of the information flowing through two-way telecommunications networks in the
year 1993, already 51% by 2000, and more than 97% of the telecommunicated
information by 2007.Today the Internet continues to grow, driven by ever greater
amounts of online information, commerce, entertainment, and social networking.

1.2CONCEPT OF PROJECT LOON:
Project loon is a research and development project being developed by Google. It
is a network of balloons travelling on the edge of space, designed to provide ubiquitous
Internet connectivity. The 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.
In 2008, Google had considered contracting with or acquiring Space Data Corp.,
a company that sends balloons carrying small base stations about 20 miles (32 km) up in the
air for providing connectivity to truckers and oil companies in the southern United States, but

The high-altitude balloons fly twice as high as airplanes, but below the range of satellites.
Each balloon provides Internet service in a 20 km (12 mi) radius covering an area of about
1,256 km2 (485 sq mi).

CHAPTER-2
PROJECT LOON
2.1 LOON DESIGN:
The loon is comprised of three parts: an envelope, solar panels and equipment.
Project Loon‟s balloon envelopes, inflatable part of the balloon, are made from sheets of
polyethylene. They are specially constructed for use in Super pressure balloons, which are
resistant to UV radiation, and is capable to function at temperature as low as -58 °F, and at
pressure as low as 1/100 atm. Balloons filled with Helium and air mixture are launched,
recycled and re-launched at a designated collecting point.
After 100 days from the launching, the balloon is ready to be taken out of
service and the gas is released from the envelope to bring down the balloon in a controlled
descent to the ground. Each balloon includes a parachute to ensure a more controlled landing.
The balloons and equipment on board can be re-used and each loon has an approximately 2-
years life time.
Solar panels power each unit‟s electronics. In full sun, these panels produce
100 watts to keep the unit running while also charging a battery for use at night. By moving
with the wind and charging in the sun, the Loon is able to power itself using only renewable
energy sources.
6. PROJECT LOON
DEPARTMENT OF ECE AVR&SVRCET

A small box containing the balloon‟s electronic equipment hangs underneath
the inflated envelope, which contains circuit boards that control the system, radio antennas to
communicate with other balloons and with Internet antennas on the ground, batteries to store
solar power so the balloons can operate during the night, and weather instruments to monitor
the weather and the conditions around them.
2.2 LOON DESIGNS:
Project Loon balloons travel around 65,000 feet 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. Due to the wind
properties, balloons can travel along latitude line with a ± 5o latitude range. 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. The Loon team can access the web-
based control system from any computer or tablet.

CHAPTER 3
WORKING OF PROJECT LOON
3.1 LOON CONNECTIONS:
Far below the loons, ground stations providing connectivity to backbone
Internet can transmit signals to the balloons up to 65 miles far. The signals would hop
forward, from one balloon to the next, along a chain of up to 5 balloons. Each balloon is
networked to one another within 30 miles with a radio transceiver as in a mesh, designed to
ensure signal reliability. A second transceiver keeps the balloon in contact hundreds of
antennas on ground area about 25 miles in diameter at speeds comparable to 3G. The
specialized antennas can be placed on homes, much like a very small satellite TV receiver.
Project Loon currently uses ISM bands (specifically 2.4 and 5.8 GHz bands) that are
available for anyone to use. There is also a back-up transceiver and a GPS on each balloon,
so Google can monitor each balloon's location.
3.2 ISM BANDS:
The industrial, scientific and medical (ISM) radio bands are radio
bands (portions of the radio spectrum) reserved internationally for the use of radio
frequency (RF) energy for industrial, scientific and medical purposes other
than telecommunications. Examples of applications in these bands include radio-frequency
process heating, microwave ovens, and medical diathermy machines. The powerful emissions
of these devices can create electromagnetic interference and disrupt radio
communication using the same frequency, so these devices were limited to certain bands of
frequencies. In general, communications equipment operating in these bands must tolerate
any interference generated by ISM equipment, and users have no regulatory protection from
ISM device operation.
8. PROJECT LOON
DEPARTMENT OF ECE AVR&SVRCET

Despite the intent of the original allocations, and because there are multiple allocations, in recent
years the fastest-growing uses of these bands have been for short-range, low power
communications systems. Cordless phones, Bluetooth devices, near field communication (NFC)
devices, and wireless computer networks all use frequencies allocated to low power
communications as well as ISM.
The ISM bands defined by the ITU-R are:

THE PIOLT TEST
In 2008, Google had considered contracting with or acquiring Space Data Corp., a
company that sends balloons carrying small base stations about 20 miles (32 km) up in the air
for providing connectivity to truckers and oil companies in the southern United States, but
didn't do so.
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.
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. After this
initial trial, Google plans on sending up 300 balloons around the world at the 40th parallel
south that would provide coverage to New Zealand, Australia, Chile, and Argentina. Google
hopes to eventually have thousands of balloons flying in the stratosphere.

ADVANTAGES&DISADVANTAGES
6.1 ADVANTAGES
The price of Internet data in many parts of the world continues to be unaffordable for
the majority of global citizens.
“Project Loon” will offer worldwide access to information to everyone, including
those who today are beyond the geographic reach of the internet or can‟t afford it.”
Project Loon will guarantee this right by taking a practical approach to information
delivery.
Project Loon„s near-term goal is to provide the entire world with broadcast data,
Internet access for everyone.
Wireless connection to the Web available for free to every person in the world.
Project Loon will also offer a humanitarian communications system, relaying public
service transmissions during emergencies in places where there is no access to
conventional communications networks due to natural disasters or man-made
restrictions on the free-flow of information.
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.

6.2 LIMITATIONS
“Cost” 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
the gas and should correct the balloon‟s equipment if any damages occurs when they
are moving at stratosphere.
Every technology has both advantages and disadvantages. So loon also has above
disadvantages. Experiments are advancing so that they can avoid above
disadvantages.

CHAPTER 7
CURRENT PROGRESS
The Project Loon pilot test began in June 2013 on the 40th parallel south*. Thirty balloons,
launched from New Zealand‟s South Island, beamed Internet to a small group of pilot testers.
The experience of these pilot testers is now being used to refine the technology and shape the
next phase of Project Loon.
Pilot test project in New Zealand.

There are many rules regarding airspace and who controls it, and also disagreements as to
how far (up) such control extends. Floating in the stratosphere means that almost certainly,
Google will always be required to seek permission from any government whose airspace the
balloons float into. In addition, while this project uses unlicensed spectrum, there's no
guarantee that will always be the case. Luckily for Google, approximately 70,000 weather
balloons are launched every year, which may mitigate some, though not all, of the legal and
regulatory issues.

FUTURE ASPECTS
MDIF plans to formally request NASA to use the International Space Station to
test their technology in September 2014. Manufacturing and launching of satellites would
begin in early 2015, and Outer net is planned to begin broadcasting in June 2015. Indian
company Specify Inc. is the first private non-profit company which is working with outernet
to provide global free Wi-Fi access. Forget the Internet - soon there will be the OUTERNET:
Company plans to beam free Wi-Fi to every person on Earth from space.
The New York Company plans to ask NASA to test their Outernet
technology on the International Space. An ambitious project known as Outernet is aiming to
launch hundreds of miniature satellites into low Earth orbit by June 2015. Each satellite will
broadcast the Internet to phones and computers giving billions of people across the globe free
online access. Citizens of countries like China and North Korea that have censored online
activity could be given free and unrestricted cyberspace. You might think you have to pay
through the nose at the moment to access the Internet. But one ambitious organisation called
the Media Development Investment Fund (MDIF) is planning to turn the age of online
computing on its head by giving free web access to every person on Earth. Known as
Outernet, MDIF plans to launch hundreds of satellites into orbit by 2015. And they say the
project could provide unrestricted Internet access to countries where their web access is
censored, including China and North Korea.
The ISS could be a test bed for Outer net technology+3 Could our Internet
one day be delivered from space?+3 Using something known as data casting technology,
which involves sending data over wide radio waves, the New York-based company says
they'll be able to broadcast the Internet around the world. The group is hoping to raise tens of
millions of dollars in donations to get the project on the road. The Outernet team claim that
only 60% of the world's population currently have access to the wealth of knowledge that can
be found on the Internet. This is because, despite a wide spread of Wi-Fi devices across the
globe, many countries are unable or unwilling to provide people with the infrastructure
needed to access the web. The company's plan is to launch hundreds of low-cost miniature
satellites, known as cubesats, into low Earth orbit. Here, each satellite will receive data from
a network of ground stations across the globe.
Using a technique known as User Datagram Protocol (UDP)
multitasking, which is the sharing of data between users on a network, Outernet will beam
information to users. Much like how you receive a signal on your television and flick through
channels, Outernet will broadcast the Internet to you and allow you to flick through certain
websites. THE OUTERNET PROJECT TIMELINE By June of this year the Outernet project
aims to begin deploying prototype satellites to test their technology. In September 2014 they
will make a request to NASA to test their technology on the International Space Station.
By early 2015 they intend to begin manufacturing and launching their
satellites. And in June 2015 the company says they will begin broadcasting the Outernet from
space. 'We have a very solid understand of the costs involved, as well as experience working
on numerous spacecraft,' said Project Lead of Outernet Syed Karim, who fielded some
questions on Reddit. 'There isn't a lot of raw research that is being done here; much of what is
being described has already been proven by other small satellite programs and experiments.
"There's really nothing that is technically impossible to this" But at the prospect of telecoms
operators trying to shut the project down before it gets off the ground, Karim said: 'We will
fight... and win.' If everything goes to plan, the Outernet project aims to ask NASA for

permission to test the technology on the International Space Station. And their ultimate goal
will be to beginning deploying the Outernet satellites into Earth orbit, which they say can
begin in June 2015.

CONCLUSION
The balloon envelopes used in the project are made by Raven Aerostar, and are
composed of polyethylene plastic about 3 mil or 0.076 mm (0.0030 in) thick. The balloons
are super pressure balloons filled with helium, stand 15 m (49 ft) across and 12 m (39 ft) tall
when fully inflated, and carry a custom air pump system dubbed the "Croce" that pumps in or
releases air to ballast the balloon and control its elevation. A small box weighing 10 kg (22
lb) containing each balloon's electronic equipment hangs underneath the inflated envelope.
This box contains circuit boards that control the system, radio antennae and a Ubiquity
Networks Rocket M2 to communicate with other balloons and with Internet antennae on the
ground, and batteries to store solar power so the balloons can operate during the night. Each
balloon‟s electronics are powered by an array of solar panels that sit between the envelope
and the hardware. In full sun, the panels produce 100 watts of power, which is sufficient to
keep the unit running while also charging a battery for use at night. A parachute attached to
the top of the envelope allows for a controlled descent and landing when a balloon is ready to
be taken out of service. In the case of an unexpected failure, the parachute deploys
automatically. The balloons typically have a maximum life of about 55 days, although
Google claims that its tweaked design can enable them to stay aloft for more than 100 days.
