Introduction It is a private, secure and reliable peer-to-peer aircraft

communications network that uses the same technology as the commercial Internet.

Similar to Satellite-based Internet access, but without the time delay.

AI began as a supporting technology for NASA’s SATS.

It provides aircraft-aircraft, ground-ground, aircraft-ground communication support in Air traffic Management, Fleet Operations & passenger support services.

Nature of Computer technology and Internet technology has changed a lot in the past 10 years and will change a lot in the next 10 years

Most of you in 1991 had not even heard of Internet, World-Wide Web, Networks, Personal Digital Assistant (PDA), Windows NT, Linux

These are all now part of Computer Technology and Internet technology

Computer and Internet

Networking TechnologyNetworking Technology

Power-Line NetworkingPower-Line Networking

Way to connect computers in home or office using electrical wiring

More convenient than phone lines Connect computer to network through the outlet that

provides power Data travels through electrical wiring Requires no new wiring and adds no cost to electric

bill Power-line networking is inexpensive method for

connecting computers in different places in home or office

Power-Line NetworkingPower-Line Networking

BluetoothBluetooth Bluetooth is new standard being developed by a group

of electronics manufacturers Will allow any sort of electronic equipment to

communicate with each other Can be used among computers, keyboard, mouse,

printer, headphone, cell phone Bluetooth-like radio communications should take place

of wires or infrared signals for connecting devices

Very small radio module to be built into each device

Wireless: No need for cables or cords to any device

Wireless NetworkingWireless Networking Creates network by sending infrared or radio signals

between computers Better than Power-line networking; some computers

are not “plugged in” to electrical outlet Laptop with wireless network card is completely

portable throughout home or office IrDA (Infrared Direct Access) is standard for devices to

communicate using infrared light pulses

Infrared devices must be in direct line of sight with each other (like TV remote… which uses same infrared technology)

Infrared is almost always “one to one” technology

Radio signals better because no line of sight requirement and ability to broadcast to multiple recipients

Comparison of 1G to 5G technologies

Satellite Internet access already commonplace Satellites orbit at several hundreds of miles above

Earth Imagine airplane-like device at approximately 60,000

feet Aircraft will be undisturbed by inclement weather and

will be flying well above commercial air traffic

Airborne InternetAirborne Internet

Why Airborne Internet? There are mainly 2 reasons for developing the AI. They are: 1. SATS (Small Aircraft Transportation System)2. Need For Higher Bandwidth.

SATS Controls Traffic in Air. Provides Internet for people in the transit.

High Bandwidtho Around 1 – 5 Mbps for Home Users.o Around 5 – 25 Mbps for Business Users.o Around 25 – 155 Mbps for Dedicated links.

Principles

To establish a robust, reliable, and available digital data channel to aircraft.

Mobile Routing is an ability of a network user to move from one network to another without loosing connectivity.

It uses the TCP/IP protocol.

It uses the network called HALO (High Altitude Long Operation).

Working of AI

(Contd) Working of AI

Implementation Systems

Three companies are planning to provide Airborne Internet by placing aircrafts in fixed patterns over hundreds of cities.

Angel Technologies – Proteus Plane.

Aero Vironment With NASA - Helios aircraft.

Sky Station International - Blimps.

Comparisons

Applications

Advantages & Features

Unique feature of these solar-electric air-craft that make then appealing platforms for telecommunications applications include:

Long flight durations up to 6 months or more.

Minimal maintenance cost due to few moving parts. High levels of redundancy Highly autonomous controls which enable one ground

operator to control multiple aircraft.

Use of solar energy to minimize fuel costs.

Conclusion

Finally Airborne Internet ,

Very much useful in field of aviation services like aircraft monitoring and air traffic management, weather information etc.

Provides passengers to access the internet at very high altitudes(in Transit).

This new service will be useful for who live in small village(Remote Places).
