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.
1. A HALO OverheadProteus Aircraft
Weight9,000 pounds at takeoff
5,900 pounds empty
Wingspa
n
77 ft 7 inches (23.7 m)
Expandable to 92 feet (28
m)
Length 56.3 ft (17.2 m)
Height 17.6 ft (5.4 m)

1 to 3 hours in
prototype tests
6 months when fully
operational
Speed19 to 25 mph (30.6
to 40.2 kmph)
3. Floating on Air
The Proteus plane will carry the network hub for the HALO Network.
Sky Station Blimp

Power Solar and fuel cells
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).
