Introduction
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.
3
What is Airborne Internet
It is an internet broadband which Provide high-speed wireless internet connection by placing aircraft in fixed path over hundreds of cities
Airborne Internet is a private, secure and reliable peer-to-peer aircraft communications network that uses the same technology as the commercial Internet.
It is convenient and has several uses like flight planning, security planning and route reservations, travel arrangements. 4
What is Airborne Internet
(AI) deliver high-speed internet :
Around 25Mb/s for business users
Around 5 Mb/s for home users
(AI) uses a network called High Altitude Long Operation (HALO).
This network is used by U.S. army.
5
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
Around 1 – 5 Mbps for Home Users.
Around 5 – 25 Mbps for Business Users.
Around 25 – 155 Mbps for Dedicated links 6
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).
7
Applications
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.
8
Implementation Systems
Three companies are planning to provide Airborne Internet by placing aircrafts in fixed patterns over hundreds of cities.
Angel Technologies – Proteus Plane.
Aerovironment With NASA - Helios aircraft.
Sky Station International - Blimps.
9
The Proteus airplane
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.
10
How AI Work
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 11
How AI Work
12
To provide the service for 24 hours, three aircraft will be used. Each one for 8 hours.
How AI Work
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.
13
Difference between Satellite and AI
AI service Satellite
Time delay Small delay Big delay
Frequency 28-38 GHz 4-6 GHz9-13 GHz
Power Low Power High Power
Cost Low Cost High Cost
14
Difference between Satellite and AI
AI does not need frequency bands license
Can service hundred-thousand of broadband subscribers
Single link delays range from ~60 m sec under the airplane to ~200 m sec at the edge of the signal
15
Advantages
Increase productivity and economic growth
Increase security, reliability, and scalability
Lower cost
It helps to achieve a broader bandwidth.
Enhanced user connectivity globally
Increase flexibility
17
Conclusion The airborne internet provide high-speed
internet.
AI has many advantage than satellite communication.
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).
