These days we know a single word that is Internet. And

to use internet only one thing comes in our mind that is

Broadband. We have so much more data to send and download

today, including audio files, video files and photos. Many Internet

users are switching to cable modems and digital subscriber lines

(DSLs) to increase their bandwidth. There's also a new type of

service being developed that will take broadband into the air that

is airborne internet. We'll take a look at the networks in

development, the aircraft and how consumers may use this

technology.

• 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 useful in providing the information about weather,

surrounding airspace environment and for aircraft-to-

aircraft communications.

• Airborne Internet (AI) is an approach to provide a general

purpose, multi application data channel to aviation.

• A primary application for AI is to track aircraft for the air

traffic control system.

• For broadband internet we use

Digital Subscriber Line(DSL), Cable

Modem, Fiber, Wireless, etc..

• Land-based lines are limited

physically in how much data they

can deliver because of the diameter

of the cable or phone line.

• Satellite Internet does not use

telephone lines or cable systems,

but instead uses a satellite dish for

two way data communications.

• Broadband internet covers Limited area.

• Unreliable- When operating at the distance from base

station the signal drops.

• Limited number of broadband subscribers.

• Bandwidth is limited

• High cost

• It is an internet broadband which Provide high-

speed wireless internet connection by placing

aircraft in fixed path over hundreds of cities.

• Deliver High speed Internet.

• AI uses a network called High Altitude Long

operation (HALO).

• This service can cover cities area around 75 mile

in diameter.

• It use high frequency between 28-38Ghz.

• The aircraft work as hub

• HALO work as wireless network with star topology

• (ISP) Internet Service Provider send the data through a

gateway to the hub in the aircraft

To provide the service for 24 hours, three aircraft will be used each for 8 hour.

• AI divide the area into different cells.

(mobile cells)

• each spot beam serves a single "cell" on the ground in a

frequency-division multiplex fashion with 5-to-1

four sub-bands for subscriber units

(A,B,C and D)

The fifth sub-band for the gateway

(E)

• Adaptation to end user environments.

• Enhanced user connectivity globally.

• Secure and reliable information transactions.

• Bandwidth on demand provides efficient use of available

spectrum.

• It helps to achieve a broader bandwidth.

• It has the potential to provide cost savings for aircrafts

operators.

Airborne internet technology has a wide

range of utilities in the field of aviation services like

aircraft monitoring and air traffic management,

weather information etc., and also provides an

opportunity for the passengers to access the

internet at very high altitudes that is, in the

aeroplanes and other conventional services.

New trend in this mobile world which is establishing

the connectivity by building network in the air.
