The Future of Internet
AIRBORNE INTERNET
PRESENTED BY:-RAHUL RAJCSE-3rd YEARITS Engg. CollegeGreater Noida
Internet Today Mobile connectivity Is a growing technology in our society today. Its growth
is fueled by the desire of people to remain connected to "the network" even while traveling.
BROADAND The word is just about every internet user’s these days is
“BROADBAND”. We have so mush more data to send and download today, that is audio files, video files and photos, that it’s clogging on our wimpy modems . Many internet users are switching from to cable modems and digital subscribers lines(DSLs) to increase their bandwidth.
SPEED The need is a fast, reliable, secure, easy and quick
access of internet.
Problem arising due to the growing needWired base connection Conventional telephone lines, for example, are capable of transmitting only 56,000 bits (56k) per second under ideal conditions - too slow and often unreliable for large file transmission.
Broadband Cable or direct subscription lines (DSL) lines can handle up to 100 million bits per second but the service is not widely available; setting up the infrastructure for a land-based broadband network with universal access requires enormous investments in time, money and resources.
Satellite based wireless connection Satellite-based Internet provides a way around the 'wired' problem - since data is sent over the air, there are no physical limitations on the amount of data that can be transmitted. The only problem with satellite Internet is a perceivable 'time lag' involved in transmitting data to and from satellites orbiting hundreds of miles above the earth. A second issue is the cost involved in sending an internet-capable satellite out of the earth's atmosphere.
Introduction Airborne Internet
Airborne Internet refers to installing a broadband network hub in an aircraft flying at 52,000 to 69,000 feet above sea level - high enough to be out of weather disturbances and way outside the flight envelope of commercial aircraft.
PEER-To-PEER NETWORK Airborne Internet is a private, secure and reliable peer-to-peer aircraft communications
network that uses the same technology as the commercial Internet .
AIRCRAFT USED AS A HUB The aircraft will provide Internet connection to places and establishments within its range.
WEATHER REPORT It is useful in providing the information about weather, surrounding airspace environment
and for aircraft-to-aircraft communications.
ORIGIN of Airborne Internet Airborne Networking began as a Tech Center idea in support of the
NASA .
SATS Project proposed in July 1999. (But not limited to SATS aircraft.)
In December 2004, the JPDO published the NGATS Plan, validating this premise, and institutionalizing a plan for network enabled operations for the NASA (i.e. NGATS)
Angel Technologies is planning an airborne Internet network, called High Altitude Long Operation (HALO) uses lightweight planes to circle overhead and provide data delivery fast.
Aero Vironment has teamed up with NASA on a solar-powered, unmanned plane that would work like the HALO network.
Small Aircraft Transportation System (SATS)
The hub and spoke system consisting of a handful of major air carriers servicing only the largest of the country’s airports is at or near saturation. To address this problem, NASA has conceived of the Small Aircraft Transportation System (SATS).
Supporting this new transportation concept is an Airborne Internet (AI).
“A client-server-based architecture will provide information services on an “Airborne Internet” to support collaborative air traffic management Aircraft and landing facilities will be interconnected nodes in a high-speed digital communications network providing instant identification and information services on demand with seamless linking to the global transportation system.” - Bruce Holmes, SATS Program Manager, NASA

HOW TO USE…
Airborne-Internet systems will require that an antenna be attached to the side of your house or work place.
Proteus will fly at heights of 15.3 km and 18.3 km and cover an area up to 75 miles(120.7 km) in diameter
PROTEUS AIRCRAFT
Weight 9,000 pounds at take-off5,900 empty
Wingspan 77ft 7 inches(23.7 m)Expandable to 92 ft.
Length 56.3 ft. (17.2 m)
Height 17.6 ft.(5.4 m)
Engine 2 turbofan engines2,300 pound of thrust
Range 18 hrs.
Speed 65 knots(75 mph/120.7 kph) to 250 knots(288 mph/463.5 kph)
The heart of Proteus plane is one-ton airborne network hub.
Network hub consists of an antenna array and electronics for wireless communication.
A 18 foot dish underneath the plane is responsible for reflecting high speed data signals from ground station to your computer
FEATURES
FLOATING ON AIR
SKY STATION International is counting on its blimp in the race to deliver high speed Internet access from high altitudes and call them as lighter-than-air platforms.
Each station would fly at an altitude of 13 miles(21 km) and provide service to an area of approximately 7,500 miles(19,000 Sq km)
ADVANTAGE
Lower Costs
Reduced Risks
Increase in productivity and economic growth
Increased flexibility
Real Time
CONCLUSION The commercial aviation’s hub and spoke system today are badly
overloaded. Thus, there is a need to bring into use the small and mid size
airports, which is only possible via the airborne internet concept. If and when those planes and blimps start circling to supplement
our current modes of connection, downloading the massive files we've come to crave for entertainment or depend on for business purposes will be a snap -- even if we live somewhere in that "last mile.“
Airborne Internet will start out with a few obvious applications, but as bandwidth capability increases, so will the number of applications…… or will it be that the number of applications will increase and in turn will create a demand for greater bandwidth? Only time will tell…
