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

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.

COMPARE/ CONTRAST TO GROUND BASED INTERNET

Bandwidth“unlimited” (Gbps)Highly restrictive

IMPLEMENTATION OF SYSTEMS

1. A HALO OVERHEAD PROTEUS AIRCRAFT

WEIGHT9,000 pounds at take off and 5.900 pounds

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

2 NASA’S SUB-SPACE PLANS HELIOS AIRCRAFTWEIGHT2.048 pounds (929kg)

WINGSPAN247ft (75.3m)LENGTH12ft(3.7m)

WINGAREA1.976 spquare ft(183.6 mtr square)

PROPULSION14 brush 2horse power, direct current electric motors

RANGE1-3 hours prototype tests, 6 months when fully operational

SPEED19-25 mph(30.6-40.2 kph)

The Helios aircraft will be equipped with

telecommunications equipment and stay airborne for six

month straight

3 FLOATING ON AIR: SKY STATION BLIMP

FUTURE ACTIVITIES

• We invited to continue applying the methadology defined above to

• 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.
