3. ABSTRACT
 The word on just about
every Internet user's lips these days is
"broadband." We have so much more
data to send and download today,
including audio files, video files and
photos, that it's clogging our wimpy
modems. Many Internet users are
switching to cable modems, Fiber
Optics and digital subscriber
lines (DSLs)to increase their bandwidth.
 Then comes the Satellite Internet
Access based on wireless connection.
 It does not use a Dialup connection or
cable connection but instead uses a
satellite dish for two way data
communication.(upload and download)

4. ABSTRACT
 There is a new type of service being developed that will take
Broadband into the air which is called as “AIRBORNE
INTERNET”
 The airborne Internet will function much like satellite-based
Internet access, but without the time delay.
 Bandwidth of satellite and airborne Internet access are typically the
same, but it will take less time for the airborne Internet to relay data
because it is not as high up. Satellites orbit at several hundreds of
miles above Earth. The airborne-Internet aircraft will circle
overhead at an altitude of 52,000 to 69,000 feet (15,849 to 21,031
meters). At this altitude, the aircraft will be undisturbed by
inclement weather and flying well above commercial air traffic.
 Networks using high-altitude aircraft will also have a cost
advantage over satellites because the aircraft can be deployed easily
-- they don't have to be launched into space.3/27/2018

Airborne Internet aims at providing
communication link between aircraft-
ground, ground-ground and aircraft-
aircraft.
This is one of the major achievements in
the aviation history by NASA’s Small
Aircraft Transportation System(SATS).
The network is intended for use in
aviation Communications, navigation and
Surveillance(CNS) and would also be
useful to businesses, private Internet users
and government agencies, especially the
military.
INTRODUCTION

6. WHAT IS AIRBORNE INTERNET
 It is private, secure and
reliable peer to peer
aircraft communication
network that uses the
same technology as the
commercial internet.
 It is a proposed network in
which all nodes would be
located in the aircraft.
 It is about information
connectivity.
 It can provide an
interconnected digital data
network between aircrafts
and aircraft to ground.

7. HISTORY
Breaking the information barrier
 In 1903, the Wright brothers broke the chains of gravity
 In 1947, Chuck Yeager broke the sound barrier.
 In 1999, Ralph Yost from the FAA Technical Center broke the
information barrier when he conceived of a system in which aircraft
would be connected with a scalable, general purpose, and multi-
application aviation data channel and treated as nodes in a network.
 But the idea of Airborne internet was first proposed at NASA
Langley Research Centre’s SATS Planning Conference in 1999.
 The goals of SATS initiative is the implementation of small aircrafts for
public transportation and later on, it was suggested that such a system
would require a peer-to-peer communication network over an aircraft.
 The Airborne Internet Consortium (AIC) is formed and is helping to
advocate this concept, which is known as the Airborne Internet.

8. THE NET TAKES FLIGHT
 The computer most people use comes
with a standard 56K modem, which
means that in an ideal situation your
computer would downstream at a rate of
56 kilobits per second (Kbps). That
speed is far too slow to handle the huge
streaming-video and music files that
more consumers are demanding today.
That's where the need for bigger
bandwidth -- broadband -- comes in,
allowing a greater amount of data to
flow to and from your computer.
 Land Based Lines are limited physically
in how much data they can deliver
because of the diameter of the cable or
phone line. In an airborne internet, there
is no such physical limitation, enabling a
broader capacity.

9. Continued…
 The airborne Internet won't be
completely wireless. There will be
ground-based components to any
type of airborne Internet network.
 The consumers will have to install
an antenna on their home or
business in order to receive signals
from the network hub overhead.
 The networks will also work with
established Internet Service
Providers (ISPs), who will provide
their high-capacity terminals for
use by the network.
 These ISPs have a fiber point of
presence-their fiber optics are
already set up.What AI will do is
provide an infrastructure that can
reach area that don’t have
broadband cables and wires.
3/27/2018
AI systems will require that an antenna be attached to
the side of your house or workplace.

10. ARCHITECTURE
 The Airborne Internet Architecture is a client-server
network system architecture
 The development will be the maturing of the Airborne
Internet to enable the full SATS(Small Aircraft
Transportation System)vision.
 In the Airborne Architecture, each Aircraft is a part of
the Peer to Peer network.(denoting or relating to
networks in which each computer can act as a server
for the others, allowing shared access to files and
peripherals without the need for a central server).

11. PRINCIPLE AND WORKING
3/27/2018
This Diagram shows how the HALO network will enable a high speed
wireless internet connection.

12. PRINCIPLES OF AIRBORNE
INTERNET
To establish a robust ,reliable and available digital data
channel to the aircrafts.
Mobile Routing is an ability of a network user to move from
one network to another network without loosing
communication.
It uses the TCP/IP protocol for specifying network
addresses and ensuring message packets arrival.
It uses the network called HALO(High Altitude Long
Operation).
HALO network is used by U.S. Air Force in 1991 Gulf war.
HALO uses light-weighted planes to circle overhead and
provide data faster than any other network.

13. 3/27/2018
The Aircraft will work as a Hub.
HALO works as wireless network with star topology.
Internet Service Provider(ISP) sends the data through the
gateway to the hub in the aircraft.
To provide service for 24 hours, 3 aircrafts will be used each
for 8 hours.

networking equipment in the air.
 The Proteus plane will fly at height of 9.5 and 1.4 miles and cover an
area up to 75 miles in diameter.
 The plane still needs to receive approval from the Federal Aviation
Administration.(FAA)
3/27/2018

17. IMPLEMENTATION SYSTEMS
 Sky Station International
o It created Blimps to beat Angel in delivery of internet access
from high altitudes.
o It calls its blimps lighter than air platforms and plans to station
these airships over at least 250 cities worldwide, one over each city.
o Each station would fly at an altitude of 13 miles(21 km) and
provide service to an area of 7500 square miles.
o Each blimp would have life span of 5 to 10 years.
o Each will be powered by solar and fuel cells and be equipped with
a telecommunication payload to provide wireless broadband
connections.
o Its user terminals will enable broadband connections of between 2
to 10 megabits per seconds (Mbps).

18. IMPLEMENTATION SYSTEMS
 Aero Vironment With NASA
These are working on a solar
powered light weight plane that
could fly over a city for 6 months
or more at 60,000 feet, without
landing.
Aero vironment plans to use
these unmanned planes as a carrier
to provide internet access.
Helios is currently in prototype
stage and still need a lot of testing
to be done to achieve the
endurance levels.
It plans to launch its system
within 3 years of receiving funds
for the project. When it does, a
single Helios airplane flying at
60,000 feet will cover service area
of 40 miles in diameter.

19. APPLICATIONS
The Airborne modules have been designed and tested to
provide wireless LAN (WLAN) and Internet connectivity
across the harshest of machine to machine environments
including:
 transportation
 medical
 warehouse and logistics
 point-of-sale (POS)
 industrial automation
 military
 scientific research
Equipment with an embedded Airborne module can be
monitored and controlled by a handheld device, by a PC in
a central location or over the Internet.

20. APPLICATIONS
 Airborne Internet (A.I.) is an
approach to provide a general
purpose, multi-application data
channel to aviation. In doing so,
A.I. has the potential to provide
significant cost savings for
aircraft operators and the FAA,
as it allows the consolidation of
many functions into a common
data channel.
A primary application for A.I.
is to track aircraft for the air
traffic control system. Many
other applications can utilize
the same A.I. data channel. The
applications available are only
limited by the bandwidth
available3/27/2018

21. APPLICATIONS
 It is not limited to SATS-class aircraft. All of aviation,
and even transportation, has the potential to benefit
from A.I.
 In case of War, for example- an airborne network
might enable military planes to operate without the
need for a communications infrastructure on the
ground. Such a network could also allow civilian
planes to continually monitor each other’s positions
and flight paths.
 It has the potential to change how aircrafts are
monitored and tracked by Air Traffic Control system
and how they exchange information with and about
other aircraft.
 Critical information such as Weather,Turbulance and
landing conditions can be transferred , as well as the
distance between aircrafts.3/27/2018

22. APPLICATIONS
 These airborne networks will overcome the last-mile barriers facing
conventional Internet access options. The "last mile" refers to the fact
that access to high-speed cables still depends on physical proximity,
and that for this reason, not everyone who wants access can have it. It
would take a lot of time to provide universal access using cable or
phone lines, just because of the time it takes to install the wires. An
airborne network will immediately overcome the last mile as soon as
the aircraft takes off.
 It will remove the pitfalls of Satellite Internet i-e Time lag and Cost in
launching.
 Remove the Drawbacks of Wired connection 56,000bits per second
only (too slow for transmission of data.)
 If Broadband were to setup worldwide(Cable or DSL), it would
require enormous investment in time ,money and resources. AI also
solved this problem.3/27/2018
