INTRODUCTION
The Airborne Internet is a proposed network in which all nodes would be located in aircraft.
Airborne Internet has the potential to change the way aircraft receive and send data, or more appropriately, information.
A.I. will provide an interconnected digital data network between aircraft and to/from the ground.
A.I. is to track aircraft for the air traffic control system
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 internet architecture, each aircraft is a part of the peer-to-peer network.
ARCHITECTURE
HOW AIRBORNE INTERNET WORKS
THE NET TAKES FLIGHT
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.
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 .
The airborne Internet won't be completely wireless .
A HALO Over Head
Angel Technologies is planning an airborne Internet network, called High Altitude Long Operation (HALO).
Proteus will fly at heights of 9.5 and 11.4 miles (15.3 and 18.3 km) and cover an area up to 75 miles (120.7 km) in diameter.
Each plane will fly for eight hours before the next plane takes off.
At the heart of Angel's Proteus planes is the one-ton airborne-network hub, which is what allows the plane to relay data signals from ground stations to your workplace and home computer.
The airborne-network hub consists of an antenna array and electronics for wireless communication.
CONSTRUCTION DETAILS
HALO AIRCRAFT
HALO NETWORK
The HALO Aircraft would provide urban and rural coverage from a single platform to provide service to 100-750000 subscribers, 40-60 mile diameter service area (1250 to 2800 square miles).
Each spot beam from the payload antenna serves a single "cell" on the ground in a frequency-division multiplex fashion with 5 to 1 frequency reuse, four for subscriber units and the fifth for gateways to the public network and to high rate subscribers.
NETWORK ACCESS
FEATURES
Seamless ubiquitous multimedia services
Adaptation to end user environments
Enhanced user connectivity globally
Rapidly deployable to sites of opportunity
Secure and reliable information transactions
Bandwidth on demand provides efficient use of available spectrum
NETWORK ARCHITECTURE
HALO NETWORK
The payload of the HALO™ Aircraft becomes the hub of a star topology network for routing data packets between any two subscribers possessing premise equipment within the service coverage area. A single hop with only two links is required, each link connecting the payload to the subscriber. The links are wireless, broadband and line of sight.
Information created outside service area is delivered to the subscriber's consumer premise equipment ("CPE") through business premise equipment ("BPE") operated by Internet Service Providers ("ISPs") or content providers within that region, and through the HALO™ Gateway ("HG") equipment directly connected to distant metropolitan areas via leased trunks.
THE HALO NETWORK
The CPE, BPE and HG all perform the same functions; use a high gain antenna that automatically tracks the HALO™ Aircraft; extract modulated signals conveyed through the air by millimeter waves; convert the extracted signals to digital data; provide standards-based data communications interfaces, and route the digital data to information appliances, personal computers, and workstations connected to the premise equipment
FIELD OF VIEW
Angel assumes that “minimum look angle” is higher than 20degrees. This value corresponds to subscribers at the perimeter of the service footprint.
The high look angle allows the sharing of this spectrum with ground-based wireless networks sine usually high gain, narrow beams are used and antenna beams of the HALO and ground-based networks will be separated in angle far enough to ensure a high degree of signal isolation.
FIELD OF VIEW
PREMISE EQUIPMENT
EASE OF INSTALLATION
ADVANTAGES
Increase productivity and economic growth
Increase security, reliability, and scalability
Reduce risk
Increase innovation
Increase flexibility
Cost effective
APPLICATONS
Helps in weather forecast, navigation, wireless communication.
Used in client-server network system.
Used in air traffic control systems.
Cheaper than satellite internet communication
It takes less time to transfer the data than satellite communication.
CONCLUSION
Airborne Internet provides aircraft to aircraft communications in support of air traffic management.
It seems that airborne internet could take off in the very near future.
Airborne Internet has the potential to change the way aircraft receive and send data.
A.I. will provide an interconnected digital data network between aircraft and to/from the ground.
