The document discusses airborne internet, which aims to provide broadband internet connectivity by placing aircraft equipped with networking equipment in fixed paths over cities. It would allow download speeds of 25Mbps for businesses and 5Mbps for homes. The technology uses a network called HALO and aircraft like the Proteus plane, which has an 18-foot dish to reflect signals. The airborne internet architecture involves user terminals connecting to the aircraft hub via antennas. Implementing it could provide benefits like increased productivity, security, and innovation compared to existing internet infrastructure.

3. 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. It is undertaking the development of the 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.

4.  It is an internet broadband which Provide high-
speed wireless internet connection by placing
aircraft in fixed path over hundreds of cities
 (AI) deliver high-speed internet :
Around 25Mb/s for business users
And around 5 Mb/s for home users
 (AI) uses a network called High Altitude Long
Operation (HALO)

5.  Airborne Internet is a private, secure and reliable peer-
to-peer aircraft communications network that uses the
same technology as the commercial Internet.
 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.
 It is convenient and has several uses like flight planning,
security planning en route reservations, travel
arrangements.

6. •The security applications including flight
tracking/deviation monitoring, in-flight video
monitoring, cockpit voice/video recording.
•This airborne internet is an approach to provide
a general purpose, multi application data
channel to aviation.
•A primary application for A.I. is to track aircraft
for the air traffic control system.
•The principle behind the A.I. is to establish a
robust, reliable, and available digital data
channel to aircraft.
Applications and principle

7.  Increase productivity and
economic growth
 Increase security, reliability,
and scalability
 Lower cost
 Increase innovation
 Increase flexibility
 Reduce risk

8. The Airborne Internet Consortium (AIC) is a
non profit research organization
composed of aviation sector participants
that collaboratively research, develop,
and promote open standards and Internet
protocols for aviation digital
communications

9.  AI does not need frequency bands
license
 Can service hundred-thousand of
broadband subscribers
 Single link delays range from ~60 msec
under the airplane to ~200 msec at the
edge of the signal
The Airborne Internet

10. AI service Satellite
Time delay Small delay Big delay
Frequency 28-38 GHz 4-6 GHz
9-13 GHz
Power Low Power High Power
Cost Low Cost High Cost
The Airborne
Internet

11.  AI divide the area into different cells.
(mobile cells)
 each spot beam serves a single "cell" on the ground in a
frequency-division multiplex fashion with 5-to-1
The Airborne Internet
four sub-bands for subscriber units
(A,B,C and D)
The fifth sub-band for the gateway
(E)

12. The Airborne Internet
To provide the service for 24 hours, three aircraft will be
used. Each one for 8 hours.

13.  This service can cover cities
area around 75 mile in diameter
 The aircraft will fly at altitude 51,000 ft
(15,500 m)
 It use high-frequency.
between 28-38 GHz
The Airborne Internet

14. Airborne Internet Architecture
Airborne-Internet systems will require that an antenna be attached to
the side of your house or work place

15.  The aircraft work as hub
 HALO work as wireless network with star topology
 (ISP) Internet Service Provider send the data through
a gateway to the hub in the aircraft
The Airborne Internet

16.  The user terminal consists of three main parts:
1 The radio frequency unit (RU)
a) MMW Antenna
b) MMW Transceiver
c) An antenna tracking unit
An antenna tracking unit uses a pilot tone transmitted from
the HALO aircraft to point its antenna at the airplane
2- The Network Interface Unit (NIU)
3- the application terminals such as PCs, telephones, video
servers, etc.
The Airborne Internet

17. The Airborne Internet

18.  The Proteus was developed by NASA
 It is designed with long wings and low wing loading
 It can fly in high-altitude
 18-foot dish underneath the plane is responsible for reflecting
high-speed data signals from a ground station to users.
The Airborne Internet

19. Implementation
The Helios aircraft will be equipped with telecommunications
equipment and stay airborne for six months straight.

20. Advantages of Airborne Internet over Existing
Systems

21. Conclusion
Thus this airborne internet technology has a
wide range of utilities in the field of aviation
services like aircraft monitoring and air traffic
management, weather information etc.,
and also provides an opportunity for the
passengers to access the internet at very high
altitudes that is, in the aero planes and other
conventional services.
Thus it is a further new trend in this mobile
world which is establishing the connectivity by
building network in the air.
