AIRBORNE INTERNET

 These days every internet users use the word BROADBAND which is used to upload and

download more data like audio, video, photo…

 Many internet users are switching to cable

modems and Digital Subcirber 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 AI will function much like satellite based

internet access without any time delay

AI 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

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 ( up and down) data communication

Upload speed is one-tenth of 5oo Kbps download

Download speed is 10 times faster than normal download

Two-way satellite consists of,

Approximately a two-foot by three-foot dish,

Two modems,

Co-axial cables between dish and modem

WORKING OF AIRBORNE INTERNET

Three companies are planning to provide high-speed

wireless inter net connection by using this AI

1. ANGEL TECHNOLOGIES planning AI called High

Altitude Long Operation (HALO) which use fligth

weight planes

2. Aero Vironment has teamed up with NASA on a solar

power unnamed plane that works similar to HALO

network

3. Sky Station International is planning for a similar thing

using blimps instead of planes

These diagram shows how the HALO Network will enable a high-speed wireless internet connection

THE NET TAKES FLIGHT

The computer most people use comes with a standard of 56K modem, which means that copmuter has a downlaod stream at a rate of 56Kbps

Land based lines are limited physically in how much data that they can deliver because of the diameter of cable or phone line, but in AI there is no such physical limitation

It takes only less time for AI to relay data that is not as high up

The AI aircraft will circle overhead at an altitude of

52.000 – 69.000 feet

These Airborne networks will overcome last-mile barries like physical proximity

This AI 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

AI systems will require that an antenna be attached to the side of your house or work place.

FUTURE ACTIVITIES

• We invited to continue applying the

methadology defined above to

• Develop AI alternatives,

• Analyze advantages and disadvantages of each alternaltive,

• Estimate of performance and cost will be made

• A separate security assesment will be

produced

• Thus this technology has a wide range of

utlities in the field of aviation 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
