INTRODUCTION
Airborne Internet is a concept that overlays computer network theory and principles into the transportation realm. The goal is to create information connectivity by providing a general purpose, multi-application data channel for people in transit. It is an approach to provide a general purpose high speed digital network to aviation. In doing so it has the potential to provide significant cost savings for aircrafts operators and the FAA, as it allows the consolidation of many functions into a common data channel. Numerous applications can use the same data channel. It gets its name from the fact that it works like the real internet.
Airborne Internet began as a supporting technology for NASA’s Small Aircrafts Transportation System. But there is no reason that A.I should be limited to SATS-class aircraft. All of aviation, and even transportation, has the potential to benefit from A.I. Airborne Internet provide a general purpose data channel that numerous applications can use. By combining application and data functionality over a common data channel, aviation has the potential to significantly reduce costs for equipage on the ground and in the aircraft.
The demand for Internet services is exploding and this creates a strong demand for broadband, high data rate service. It is expected that there will soon be a worldwide demand for Internet service in the hundreds of millions. The growth in use of the World Wide Web and electronic commerce will stimulate demand for broadband services.
WORLD OF AIRBORNE INTERNET
WHY AIRBORNE INTERNET?
There are mainly two reasons for the development of Airborne Internet. They are,
SMALL AIRCRAFTS TRANSPORTATION SYSTEM:
The first reason for the development of A.I is SATS. It began as a supporting technology for the NASA’s SATS. NASA is creating an infrastructure for fleets of small aircraft. People won’t have to fly between large cities on jet airliners. Instead, they will be able to fly themselves right to where they want to go. This would speed up air travel. But, it would need a major change in air traffic control to be able to manage thousands of small airplanes filling the skies. That’s where the “Airborne Internet” comes in. This project is being developed along with the Small Aircraft Transportation System (SATS). The SATS is studying the possibility of a system of 2- to10-passenger airplanes. People could fly these small airplanes to and from small community or neighbourhood airports. Before this system becomes areality, there are still many bugs that need to be worked out. Communication is one of the problems that will have to be fixed. The SATS would lead to thousands of inexperienced pilots flying airplanes. They would be flying to and from small airports that don’t usually have much traffic. Without major changes in air traffic control, the chances of plane crashes would greatly increase. That’s why NASA is developing the Airborne Internet.
When people travel, they experience “connectivity down time” in which they are detached from the information that their network provided. Wireless networks are rapidly emerging to help fill this void. People that travel with laptops or personal digital assistants can obtain short term network connectivity from a business establishment when they stop for a break. Airport terminals are becoming popular “hot spots’ for wireless connectivity as people have time before and between flights to connect to the wireless network. The “human connectivity imperative” shows us a glaring absence of network connectivity during travel. While in motion on an aircraft, for example, people again lose the ability to connect. We design transportation systems to interconnect to complimentary forms of transportation.But these designs have ignored the information connectivity needs of the people who use it. The time people spend in transit could be turned into more productive time if network connectivity were available. This can be accomplished using the A.I.
NEED FOR A HIGHER BANDWIDTH:
The second reason is related with the need for a higher bandwidth. The computer most people use comes with a standard 56K modem, which means that in an ideal situation the 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 the 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.
