2. ABSTRACT
These days every internet users use the word
BROADBAND which is used to upload and to
download more data like audio, video, photo…
Many internet users are switching to cable
modems and Digital Subscriber Lines to increase
their bandwidth.
There is a new type of service being developed
that will take broadband into the air which is
called as “AIRBORNE INTERNET”.
The Airborne Internet will function much like
satellite based internet access without any time
delay.
3. INTRODUCTION
Airborne Internet is a private, secure and reliable
peer-to-peer aircraft communication network.
This implementation is used to connect aircraft
to a groundbased internet access node,including
the information which passed across the
communication link.
It is useful in providing information about
Weather, Surrounding airspace environment and
for aircraft- to- aircraft communications.
4. HOW DOES SATELLITE INTERNET
OPERATE?
Satellite internet replaces the dial up connection
for telephone connection, cable connection for
television.
Satellite internet does not use telephone lines or
cable systems ,but instead uses a satellite dish
for two way(upload and download)data
communication.
Upload speed is one-tenthof 500 kbps download.
Download speed is 10 times faster than normal
download.
5. Two-way satellite consists of,
Approximately a two-foot by three-foot dish,
Two modems,
Co-axial cables between dish and modem.
6. WORKING OF AIRBORNE INTERNET
Three companies are planning to provide high -
speed wireless Internet connection by using this
Airborne Internet.
1)ANGELTECHNOLOGIES planning Airborne
Internet called High Altitude Long Operation
(HALO), which use light weight palnes.
2)Aero Vironment has teamed up with NASA on a
solar power unnamed palne that works similar to
HALO network
3)Sky Station International is planning for a similar
thing using blimps instead of planes.
8. THE NET TAKES FLIGHT
The computer most people use comes with a
standard of 56k modem, which means that
computer has a download stream at a rate of
56 kbps.
Land based lines are limited physically in
how much data thety can deliver because of
the diameter of cable or phone line,but in
Airborne Internet there is no such physical
limitation.
9. It takes only less time for Airborne internet to
relay data that is not as high up.
The Airborne-Internet aircraft will circle
overhead at an altitude of 52,000 - 69,000
feet(15,849 – 21,031 mts)
These Airborne networks will overcome last-mile
barriers like physical proximity.
This Airborne internet is not completely wireless,
the consumers has to install an antenna on their
home or business in order to receive signals from
network hub over head.
12. IMPLEMENTATION OF SYSTEMS

15. FUTURE ACTIVITIES
We intend to continue applying the methadology
defined above to
Develop Airborne Internet alternatives,
Analyze advantages and disadvantages of each
alternative,
Estimates of performance and cost will be made
and
A separate security assessment will be produced.
16. CONCLUSION
Thus this technology has a wide range of utilities
in the field of avitation services like aircraft
monitoring, 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 aeroplanes and in other
conventional services.
