IntroductionIntroduction

Airborne Internet is a private, secure and reliable peer-to-

peer aircraft communications network that uses the same

technology as the commercial Internet.

It is an implementation which connects aircraft to a ground-

based Internet access node, including the information which

is passed across this communication link.

It is useful in providing the information about weather,

surrounding airspace environment and for aircraft-to-aircraft

communications.



This Airborne Internet (A.I.) is an approach to provide

a general purpose, multi-application data channel to

aviation.

A primary application for A.I. is to track aircraft for

the air traffic control system.

A.I. began as a supporting technology for NASA·s SmallAircraft Transportation System (SATS).

The principle behind the A.I. is to establish a robust,

reliable, and available digital data channel to aircraft.

How does satellite InternetHow does satellite Internet

operate?operate?

Satellite Internet does not use telephone lines or cable

systems, but instead uses a satellite dish for two-way

(upload and download) data communications.

Upload speed is about one-tenth of the 500 kbps

download speed. Cable and DSL have higher download

speeds, but satellite systems are about 10 times faster

than a normal modem.

Firms that offer or plan to offer two-way satellite

Internet include StarBand, Pegasus Express, Teledesic and

Tachyon.



TWOTWO--WAY SATELLITE WAY SATELLITE

Two-way satellite Internet consists of:

Approximately a two-foot by three-foot dish

Two modems (uplink and downlink)

Coaxial cables between dish and modem.

The key installation planning requirement is a clear

view to the south, since the orbiting satellites are over

the equator area. And, like satellite TV, trees and heavy

rains can affect reception of the Internet signals.

The Net Takes FlightThe Net Takes Flight

Bandwidth of satellite and airborne Internet access are

typically the same, and it takes less time.

The airborne-Internet aircraft will circle overhead at an

altitude of 52,000 to 69,000 feet (15,849 to 21,031 meters).

An airborne network will immediately overcome the last

mile as soon as the aircraft takes off.



The airborne Internet won't be completely wireless.

There will be ground-based components.

The networks will also work with established Internet

Service Providers (ISPs).



Airborne-Internet systems will require that an antennabe attached to the side of your house or work place.



IMPLEMENTATION S Y STEMS:IMPLEMENTATION S Y STEMS:

A HALO Overhead

The Angel Technologies is developing an air borne internet network

through its HALO Network. The centerpiece of this network is the

Proteus plane, which will carry wireless networking equipment into

the air.

The Proteus plane will carry the network hub for the HALO Network



The Proteus plane, developed by Scaled Composites is

designed with long wings and the low wing loading needed

for extended high-altitude flight. Wing loading is equal to the

entire mass of the plane divided by its wing area.



This diagram shows how the HALO Network will enable a high-speed

wireless Internet connection

Sky Station International

Sky Station International is counting on its blimps,in

the race to deliver high-speed Internet access from high

altitudes and calls them as lighter-than-air platformsand plans to station these airships,one over each city.

Each station would fly at an altitude of 13 miles (21

km) and provide wireless service to an area ofapproximately 7,500 square miles (19,000 square km).



NASA's SubNASA's Sub--space Plans:space Plans:

NASA is also playing a role in a potential airborne Internet system

being developed by AeroVironment.

The Helios aircraft will be equipped with telecommunications

equipment and stay airborne for six months straight.



ConclusionConclusion

Thus this airborne internet technology has a wide range of

utilities in the field of aviation services like aircraftmonitoring and air traffic management, weather information

etc.,

It also provides an opportunity for the passengers to access

the internet at very high altitudes that is, in the aeroplanes

and other conventional services. Thus it is a further newtrend in this mobile world which is establishing the

connectivity by building network in the air.
