X To LOONS PRESENTED BY 4TH CSE

INTRODUCTION : In 2008, GOOGLE started an initiative to make everyone experience the flavor of LTE technology using LOONS.

Initiators: Internet and communication expert : CYRUS BEHROOZI Chief technician: RICH DEAVULE Wearable expert: MIKE CASSIDY Internet and communication expert : CYRUS BEHROOZI Project head: TOM MOORE

WHAT IS A LOON:

LOON: A LOON is a helium balloon technology which was introduced to make 4G internet as a world wide useable network. As per the recent survey 2/3 rd of the world population is unable to have a basic internet access, so avoid this kind of situation “THE PROJECT X” is introduced.

STEPPING LOONS: The origin of LOONS was laid by GOOGLE in 2008, using a garbage bag balloon as the first prototype. Project Loon began on 14June 2013 with an experimental pilot in New Zealand, where a small group of Project Loon pioneers tested Loon technology.

TECHNOLOGY Loon balloons go where they’re needed by rising or descending into a layer of wind blowing in the desired direction of travel. By partnering with Telecommunications companies to share cellular spectrum.

TECHNOLOGY The signal is then passed across the balloon network and back down to the global Internet on Earth. These loons float in the wind layer by the wind data provided by the (NOAA)National Oceanic and Atmospheric Administration.

CONNECTIVITY:

Loon design components: Stratosphere Envelopes Solar planes Electronics & antennas Navigation Turbines Batteries Chicken little Rocket roosters Parachute ISP

STRATOSPHERE: The atmospheric area above the climatic conditions. Ranges from 10 to 60km. Challenges : 1% air pressure Thinner atmosphere Temperature up to -50degrees Less protection from UV radiation

ENVELOPE It is named as envelope because of its feasible model of open and close prototype. The basic envelope was made up of polyethylene plastic by Raven Aerostar. It is a helium filled balloon made of thickness 0.076mm.

SOLAR PANELS: The LOONS consists of two light weight lithium solar panels made of microcrystal cells. This solar panels produce 100wts of energy during the daytime and also charge the batteries for the night time usage. These solar panels always face towards the sunlight by spinning with the help of transmitters.

Electronics & Antennas 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 . With, Internet antennas on the ground, and lithium ion batteries to store solar power so the balloons can operate throughout the night.

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

Turbines The basket of the LOON consists of two turbines on either sides. The turbines helps the LOONS to stay in a particular path of wind flow in the stratosphere. These turbines uses 10wts of power of solar panels to maintain their flight path. These turbines are connected to the transceiver which gets signals from the ground stations.

Batteries The batteries which are used in the LOONS are made up of lithium ion cells. The capacity of the battery is 13000Mah. These are charged by solar energy.

Chicken little The chicken little is a technology implemented after the an unexpected incident in NEWZEALAND in 2014. Chicken little is nothing but an egg like balloon placed inside the original LOON. This chicken little is technically known as BALLONET.

Rocket roosters Google decided to implant rocket roosters in the basket of the loon after an incident in 2015 KENYA.

Parachute It is a safe side action perform to save the equipment basket . This balloon opens spontaneously in fraction of seconds.

ISP INTERNET SERVICE PROVIDER It helps in reach of network by cellular spectrums.

ADVANTAGES Low cost with less round trip. Higher capacity via wireless meshes. Remote accessing.

DISADVANTAGES Frequent hardware malfunction Less stable security. Short span.

FUTURE SCOPE Yes, Till the worlds surfing
