- 1. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 1 CHEPTER: 1 INTRODUCTION Flying Hope: Balloon bring Internet to everywhere Today only 2.7 billion people – a little more than one third of the world’s population have Internet access. This fact can be attributed to many reasons, but the most important factor is the scarcity of intensive capital necessary for Internet infrastructure implementation in many developing areas. The rapid development in wireless telecommunication industry has boosted another revolution in data services. Even though there are more than 1 billion Smartphone subscribers in the world, the majority of them still don’t have data access due to the costly data plan in many countries. On the other hand, the vast majority of the prices people pay for data plans go directly towards covering the tens of billions of dollars spent each year building the infrastructure to deliver the connections. Unless the infrastructure expansion becomes more efficient, the industry cannot sustainably serve everyone. Bring majority of the global population into Internet community is one of the greatest challenges of our generation, and now we see hope from the Google Project Loon – a network of balloons travelling on the edge of space, designed to provide ubiquitous Internet connectivity free of terrestrial constrains and with an affordable rate worldwide.

Please provide stepwise long-term strategy for the Loon to set a development plan in terms of both marketing and technology. 1.1Background Project loon is a research and development project being enveloped 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. Fig 1.2: Basic concept behind “Google project loon”
- 4. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 4 CHEPTER: 2 PROJECT OVERVIEW 2.1 What is ProjectLoon? Many of us think of the Internet as a global community. But two-thirds of the world’s population does not yet have Internet access. Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas, help fill coverage gaps, and bring people back online after disasters. 2.2 The technology Project Loon balloons float in the stratosphere, twice as high as airplanes and the weather. In the stratosphere, there are many layers of wind, and each layer of wind varies in direction and speed. Loon balloons go where they’re needed by rising or descending into a layer of wind blowing in the desired direction of travel. People can connect to the balloon network using a special Internet antenna attached to their building. The signal bounces from this antenna up to the balloon network, and then down to the global Internet on Earth. 2.3 Where loon has been Project Loon began in June 2013 with an experimental pilot in New Zealand, where a small group of Project Loon pioneers tested Loon technology. The results of the pilot test have been used to improve the technology, and continued refinements are now being tested in an ongoing series of research flights in California’s Central Valley. 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.
- 5. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 5 By moving with the wind, the balloons can be arranged to form one large communications network Situated between 10 km and 60 km altitude on the edge of space, the stratosphere is named after the different strata, or layers, of wind within it. But the extreme altitude also presents unique engineering challenges: Air pressure is 1% of that at sea level, 1. temperatures hover around -50°C, and 2. A thinner atmosphere offers less protection from the UV radiation and temperature swings caused by the sun’s rays. Fig 2.1: working area of loon in this project
- 6. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 6 CHEPTER: 3 LOON DESIGN The loon is comprised of three parts: an envelope, solar panels and equipment. Envelope Solar panel Equipment Fig 3.1: Project loon balloon 3.1 Envelope: The balloon envelope is the name for the inflatable part of the balloon. Project Loon’s balloon envelopes are made from sheets of polyethylene plastic and stand fifteen meters wide by twelve meters tall when fully inflated. The balloon powers itself by two renewable energies, sunlight and wind. Fig 3.2: Actual image of loon
- 7. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 7 Its envelope is made from sheets of Mylar which is a brand for a thin strong polyester film about 0.076 mm thick. Such super pressure balloons require Mylar since it strongly keeps from stretching and popping at even high altitude. It is built to resist higher pressures than a normal weather balloon which reaches usually at an altitude of40 km (25 mi). Inside envelope, there is another chamber, called bladder. To have the balloon descended, a fan powered by the solar energy fills the bladder with air to make it heavier. Likewise, the fan vents air in the bladder, which causes it to rise. The balloon can move up or down a 1.7 km (1 mi) range through the bladder system. This system can help to choose suitable wind currents in stratosphere. It also releases some air inside out of the envelope to relieve pressure. When being out of the service, it releases gas from the envelope and descends slowly to the ground. It rarely happens, but when the balloon drops quickly, it uses the parachute on the top of the envelope. 3.2 Solarpanel: Fig 3.3: Solar panel Each 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.
- 8. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 8 Fig3.4: Actual image of solar panel which is used in this project By moving with the wind and charging in the sun, Project Loon is able to power itself using only renewable energy sources. 3.3 Equipment: Fig 3.5: Equipment A small box containing the balloon’s electronic equipment hangs underneath the inflated envelope, like the basket that is carried by a hot air balloon. Fig 3.6: This is the first prototype of loon equipment. The parachute is stuffed into the hole in the centre.
- 9. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 9 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. Fig 3.7: What goes up in to atmosphere

Page 10 CHAPTER: 4 LOON WORKS Fig 4.1: Illustrate working of loon A user with the specialized antenna sends signals via a radio frequency over ISM bands to a balloon close to him/her. The balloon sends the signals to neigh boring balloons. Eventually, the signals reach the balloon which is connected to the local Internet. The wireless mesh network is constantly adjusting as balloons move. Any balloon is able to connect the Internet to a base station which has Internet connectivity and then receives Internet data and forwards them via balloons in the sky to the destination. Finally, the balloon close to the request user broadcasts the data to the grounds via a radio frequency over ISM bands. The special antenna installed the outside of home receives data and decrypt the data. The wireless mesh network should be constantly adjusting as balloons move. It covers an area of an around 40 km (28 mi) diameter circle which is twice the area of New York City. Thousands of balloons can cover the whole world. Currently, its lifetime is only a few weeks, but Google anticipates that they can be in the sky hundreds of days in future.

Page 11 4.1 Circuitry and Transmission Each balloon carries a payload of about 10 kg, including but not limited to radio antenna, several sensors, altitude control system, processor chips and batteries. Figure is a possible patent diagram of the circuitry8. The on-board antenna uses a Ubiquities Network Rocket M2 as a WIFI transceiver. A customized Linux OS is also loaded on a processor chip to manage and transmit network and location data. The OS is loaded with software that can log onto remotely via the web.

- 13. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 13 CHAPTER: 5 Loons 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. There are several ground stations with transceivers similar to that on the balloon, but they are high-powered Ubiquities AirMax/Rocket M5 (operating at 5.8 GHz).10 the Network is designed as a mesh layout to ensure reliability. A ground station already Connected via either fibre or other backbone infrastructure to the internet, beams Signal to any nearby balloon. The first balloon that receives the signal, then Forwards or hops the signal up to 5 other balloons on its same path in sequence, a Distance of about 100 km (62 miles). Figure 9 shows the mesh structure of Loon Fig 5.1: Mesh network of Loon
- 14. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 14 Each balloon then hops the WIFI signal to ground users with coverage of about 1,256km2 (780 sq miles), in context the twice the size of New York City. Users can receive Signal via Smartphone’s or customized dual-polarization dipole antenna through an Access point. 5.1 Antenna: Fig 5.2: Antenna use in project loon It can provide wireless Internet connectivity to ground areas at up to 10Mbps (3G speed). There are three kinds of communications: balloon-to-balloon network and balloon-to-ground station or subscribers’ network, balloon to antenna network. It has specialized radio antennas to support two networks. It currently uses ISM bands specifically 2.4 and 5.8 GHz bands because they are typically unlicensed radio frequencies around the world, which means Google is able to avoid negotiating with local governments to purchase specific radio frequencies. Additionally, this also avoids interferences and reaches much further distances. Because it does not support Wi-Fi, Smartphone’s such as I-Phone are not able to establish connections directly to balloons. 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. Figure shows current iteration of the ground receiver antenna Fig 5.3: Dual polarized dipole antenna for the receiver

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. 6.1 How Loon flies NAVIGATING WITH THE WIND Fig 6.1: loon navigation with wind Winds in the stratosphere are stratified, and each layer of wind varies in speed and direction. 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. 6.2 Stratosphere Situated on the edge of space, between 10 km and 60 km in altitude, the stratosphere presents unique engineering challenges: air pressure is 1% that at sea level, and this thin atmosphere offers less protection from UV radiation and dramatic temperature swings, which can reach as low as -80°C. By carefully designing the balloon envelope to withstand these
- 17. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 17 conditions, Project Loon is able to take advantage of the stratosphere’s steady winds and remain well above weather events, wildlife and airplanes. 6.3 Stratospheric Environment Because the wind below 10km of altitude is not favourable, and because balloons cannot be positioned even above that troposphere, an algorithm is developed to control Movement or flow of the balloons based on national wind data, just like the sailing of Boat to shoreline, adjusting them along right currents in the direction of waves of the Wind. Figure below shows altitude levels above the atmosphere and somewhat indicate That theoretically, radio waves behave well in free space, with no interference of Signal, and power is attenuated by path loss coefficient lower than 2 Fig Fig 6.2: Stratosphere by altitude

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. Fig 7.1: Area covered by pilot test in New Zealand The journey Huge thanks to our pilot testers for taking the first step with us. Watch as Charles, a Project Loon pilot tester, connects to balloon-powered Internet for the first time. Fig7.2: Project loon pilot tester Charles connect s the balloon provide internet for fist time Paul, an operations team lead, uses a red sounding balloon to test the wind direction at the launch site.

This ensures the delicate envelope isn’t damaged by gravel or spiky grass. The balloon ascends to the stratosphere. The Nimmo family was the first to connect to balloon-powered Internet. Our youngest pilot tester was just a few yare old. If you are interested in learning how to become a Project Loon pilot tester for a future set of test launches Fig 7.4: Path of balloon in pilot test

International politics
- 22. GOOGLE PROJECT LOON Computer Department, MSCET, Surat. Page 22 CONCLUSION Long distance tracking experiment of loon on 40th parallel south 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
