Project Loon is Google's initiative to provide internet access to rural and remote areas using high-altitude balloons. The balloons travel in the stratosphere and connect to each other to form a wireless network with a ground range of about 80 km. Users need a specialized antenna to connect to balloons passing overhead. Google has conducted several pilot tests involving dozens of balloons to test connectivity and navigation capabilities. While the technology could expand internet access globally, challenges include high maintenance costs to replace balloons regularly.
In recent years, access to the Internet has become increasingly important for individuals’ and
communities’ economic productivity, as well as improved access to goods and services, education,
government services and more. Some in the developed world, including First Lady Michelle Obama [1],
have even begun to refer to Internet connectivity as a universal right.
In reality, however, Internet access is very far from universal. As of 2013, 4.4 billion people — over
60% of the world’s population — were not connected to the Internet [2]. And, while Internet penetration
is increasing, the rate of its increase has slowed slightly, from around 15% a year in the mid ’00s to
around 10% in the late ’00s. If this trend continues, over half the global population will still be offline in
2017.
The document discusses Project Loon, which aims to provide internet access using high-altitude balloons. It details the key components of the balloons, including the polyethylene envelope, solar panels, and control box containing wifi and communication equipment. The balloons navigate the stratosphere using wind currents and connect to ground stations to provide internet coverage for remote and rural areas, helping after natural disasters. While the technology offers advantages like speed and increased access, it also faces challenges in cost and maintaining the balloons which only operate for a few weeks. Overall the project is seen as having potential to successfully connect underserved communities.
Project Loon is a Google project that aims to provide internet access to rural and remote areas using high-altitude balloons. The balloons float in the stratosphere twice as high as airplanes, acting as floating cell towers. Each balloon is equipped with a solar panel and electronics to power a wireless connection. The balloons are maneuvered by adjusting their altitude to ride wind currents, forming a network that beams the internet signal from balloon to balloon. The goal is to deliver broadband-like internet to people worldwide who currently lack reliable access.
Google Loon is a project that aims to provide internet access to rural and remote areas using balloons floating in the stratosphere. The balloons carry communications equipment that can connect to ground-based antennas, relaying internet signals. They are arranged in a network and steered by winds to desired locations. Each balloon provides connectivity for an area about 40km in diameter. This could help connect people in places that lack traditional internet infrastructure and bring connectivity after disasters. However, challenges include controlling balloon movements, short lifespan, and security/privacy concerns over data.
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.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

21. CONCLUSION
Internet connectivity and connectivity become one of the basic needs in
modern human daily life . An innovative scalable idea like the Google project
loon would aid and benefit remote areas of the world as well as population to
reap to reap the benefits of modern communication. It would also provide
backbone communications during and after natural disasters when ground
infrastructure is scarce or destroyed.
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 and helping fill coverage gaps , and bringing people back online after natural disasters.
Each balloon can provide connectivity to a ground area about 80 km in diameter using a wireless communications technology called LTE. To use LTE, Project Loon partners with telecommunications companies to share cellular spectrum so that people will be able to access the Internet everywhere directly from their phones and other LTE-enabled devices. Balloons relay wireless traffic from cell phones and other devices back to the global Internet using high-speed links.
Project Loon balloons travel approximately 20 km above the Earth's surface in the stratosphere, well above airplanes, wildlife, and weather events. In the stratosphere winds are stratified, and each layer of wind varies in speed and direction. To get balloons to where they need to go, Project Loon uses predictive models of the winds and decision-making algorithms to move each balloon up or down into a layer of wind blowing in the right direction. By moving with the wind, the balloons can be arranged to provide coverage where it’s needed.
LAUNCHING
Our custom-built Autolaunchers are designed to launch Loon balloons safely and reliably at scale. Huge side panels provide protection from the wind as the balloon is filled and lifted into launch position, and then the crane is pointed downwind to smoothly release the balloon up into the stratosphere. Each crane is capable of filling and launching a new balloon into the Loon network every 30 minutes. We have flown over 25 million km of test flights to date since the project began - with one of our record-breaking balloons surviving for 190 days aloft in the stratosphere.
1.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 -50°c
-A thinner atmosphere
-Less protection from the UV radiation
3. Suitable because this sphere is having steady stratospheric winds.
It has three main component
The inflatable part of the balloon is called a balloon envelope. A well-made balloon envelope is critical for allowing a balloon to last around 100 days in the stratosphere. Loon’s balloon envelopes are made from sheets of thin and very light polyethylene plastic, and they measure fifteen meters wide by twelve meters tall when fully inflated with helium or hydrogen. 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.It is strong enough to lift the flight computer and other electronics whose weight is 10 kg.
Each balloon’s electronics are powered by an array of solar panels. The solar array is a flexible plastic laminate supported by a light-weight aluminum frame. It uses high efficiency monocrystalline solar cells. The solar array is mounted at a steep angle to effectively capture sunlight on short winter days at higher latitudes. The array is divided into two sections facing in opposite directions, allowing us to capture energy in any orientation as the balloons spin slowly in the wind. The panels produce approximately 100 Watts of power in full sun, which is enough to keep Loon’s electronics running while also charging a battery for use at night. By moving with the wind and charging in the sun, Project Loon is able to power itself using entirely renewable energy sources.
A small box containing the balloon’s electronics hangs underneath the inflated envelope, like the basket carried by a hot air balloon. This 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.
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.GPS for tracking location, sensors to monitor and record weather conditions, andLinux based computer.
The 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
Each balloon can provide connectivity to a ground area about 40 km in diameter at speeds comparable to 3G.
Each balloon is equipped with a GPS for tracking its location .
The balloons use antennas equipped with specialized radio frequency technology.
Project Loon currently uses ISM bands that are available for anyone to use.
it requires users to install a specialized antenna the outside
of their home to receive the signal from a balloon near their home and to decrypt the signal.
This way is very similar to the usage of satellites.
Antenna: $500
CONNECTION
High speed internet is transmitted up to the nearest balloon from our telecommunications partner on the ground, relayed across the balloon network, and then back down to users on the ground. We have demonstrated data transmission between balloons over 100 km apart in the stratosphere and back down to people on the ground with connection speeds of up to 10 Mbps, directly to their LTE phones.
The Project Loon team tracks the location of every balloon using GPS, coordinating directly with the local air traffic control to bring each one safely to ground targeting sparsely populated areas. When a balloon is ready to be taken out of service, the lift gas keeping the balloon aloft is released and the parachute deploys automatically to bring the balloon to the ground in a controlled descent. Our recovery teams then collect the equipment for reuse and recycling.
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.
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
Since Hurricane Maria made landfall in Puerto Rico, causing significant damage to the connectivity infrastructure, we have been working hard to see if it was possible to bring some basic internet connectivity back to the island. Thanks to the support of the Government of Puerto Rico, the FCC, the FAA and a range of spectrum partners, we are now collaborating with AT&T to deliver emergency internet service to some of the hardest hit parts of the island.While Project Loon is still an experimental technology and we’re not quite sure how well it will work, we hope this can be of some help to the people of Puerto Rico at this time.
“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.
