The document discusses Airborne Internet (AI), which provides internet access to aircraft. AI uses high-altitude planes, blimps, and drones stationed 60,000 feet above ground to function as flying cell towers, creating a wireless network for aircraft and users on the ground. It operates similarly to satellite internet but without transmission delays. Three companies have proposed implementations using planes, drones, and blimps to provide coverage over hundreds of cities. AI would benefit aviation services and allow passengers to access internet during flights, including in remote areas.

3. 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.

4. Computer and Internet
 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

5. Networking Technology
Power-Line Networking
Way to connect
computers in home or
office using electrical
wiring

6. Power-Line Networking
 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

7. Bluetooth
 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

8.  Very small radio module to be built into each
device
 Wireless: No need for cables or cords to any
device

9. Wireless 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

10.  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

technologies

13. Airborne Internet
 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

14. 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 Bandwidth
o Around 1 – 5 Mbps for Home Users.
o Around 5 – 25 Mbps for Business Users.
o Around 25 – 155 Mbps for Dedicated links.

15. 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).

16. Working of AI

17. (Contd) Working of AI

18. Implementation Systems
 Three companies are planning to provide Airborne
Internet by placing aircrafts in fixed patterns over
