BACKGROUND

Given the lack of infrastructure to support the current and projected demands for broadband data communication, an intense race has begun to deploy broadband networks. To satisfy businesses and consumers, Internet Service providers ("ISPs") are the majors in delivering internet access service.
Today the access service is provided by five types of competitors:
• National ISPs ( e.g. AOL, CompuServe, Microsoft Network, VSNL)
• Regional Bell Operating Companies ("RBOCs")
• Independent (Local) ISPs
• Cable Operators
• Wire service providers (Satellites, or terrestrial wireless via millimeter waves at the LMDS and 38 GHz bands, wireless local loop at the PCS bands, or packet relay at ISM )
About 70 percent of homes occupied by customers are being served by large national ISPs. The remaining 30 percent of customer's homes are being served by local ISPs that range in size from hundreds to tens of thousands of customers. Most consumers are utilizing 29\8.8 Kbps dial-up modems, and a small percent have already migrated to 56 Kbps modems. Most businesses are utilizing DS-1 connections (1.544Mbps).

The Local ISP

The local ISPs are perhaps the most entrepreneurial and fastest growing segment of the market, expanding at rates approaching 75 percent per year. In order to maintain this rapid rate of growth in the face of new competition from the RBOs and the cable companies, these local ISPs are anxious to adopt new technologies that will allow them to differentiate their services.
The local ISPs think they will be required to provide megabit per second rates to homes and business in order to survive. However, they are precluded from using the cable infrastructure as cable companies are viable competitors to them. Similarly, the RBOCs plan to offer high-speed Internet access through Digital Subscriber line ("DSL") services and may also compete directly with the local ISPs. Whereas, the HALO Network will allow the ISPs to offer distance-insensitive connections within the HALO Network service area, bypassing the Local Exchange Carriers and Interchange Carriers, to substantially reduce their cost of service.

INTRODUCTION TO AIRBORNE INTERNET

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. There's a new type of service being developed that will take broadband into the air.
The communication payload of HALO aircraft is at the apex of a wireless super-metropolitan area network. The links are wireless, broadband and line of sight. Subscribers access service on demand and will be able to exchange video, high-resolution images, and large data files. Information addressed to non-subscribers or to recipients beyond the regions served by the HALO network will be routed through the dedicated HALO Gateway connected to the public switched network or via business premise equipment owned and operated by service providers connected

HALO NETWORK

Overall Concept

The attributes of the HALO™ Network are illustrated in the fig. below. Many types of subscribers will benefit from the low price of HALO™ Network broadband services schools, families, hospitals, doctor's offices, and small to medium size businesses. The equipment will connect to existing network and telecommunications equipment using standard broadband protocols such as ATM and SONET. The HALO™ Gateway provides access to the Public Switched Telephone Network (PSTN) and to the internet backbone for such services as the World Wide Web and electronic commerce.

INTRODUCTION

DEFINATION:

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 an implementation which connects aircraft to a Ground-based Internet access node, including the information which is passed across this communication link. It provides airborne access to wealth of Internet information and resources. It is convenient and has several uses like flight planning, enroute reservations, travel arrangements. It is useful in providing the information about weather, surrounding airspace environment and for aircraft-to-aircraft communications. The security applications include flight tracking/deviation monitoring, in-flight video monitoring, cockpit voice/video recording.
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 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.May other applications can utilize . Data channel.
The applications available are only limited by the bandwidth available. A.I. began as a supporting technology for NASA’s Small Aircraft Transportation System (SATS). 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. The principle behind the A.I. is to establish a robust, reliable, and available digital data channel to aircraft.

THE LOCAL ISP :

The local ISPs are perhaps the most entrepreneurial and fastest growing segment of the market, expanding at rates approaching 75 percent per year. In order to maintain this rapid rate of growth in the face of new competition from the RBOs and the cable companies, these local ISPs are anxious to adopt new technologies that will allow them to differentiate their services.

However, they are precluded from using the cable infrastructure as cable companies are viable competitors to them.

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..
Several companies have already shown that satellite Internet access can work. 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. However, the airborne Internet will actually be used to compliment the satellite and ground-based networks, not replace them. 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.

OVERALL CONCEPT:

The attributes of the HALO™ Network are illustrated in the fig. below. Many types of subscribers will benefit from the low price of HALO™ Network broadband services schools, families, hospitals, doctor's offices, and small to medium size businesses. The equipment will connect to existing network and telecommunications equipment using standard broadband protocols such as ATM and SONET. The HALO™ Gateway provides access to the Public Switched Telephone Network (PSTN) and to the internet backbone for such services as the World Wide Web and electronic commerce.

SERVICE ATTRIBUTES:

There are various classes of service to be provided .A consumer service would provide 1-5 Mbps communication links. A business service would provides 5-12.5 Mbps links .Since the links would be "bandwidth-on-demand," the total available spectrum would be time-shared between the various active sessions. The nominal data rates would be low while the peak rates would expand to a specified level. A gateway service can be provided for "dedicated" links of 25-155 Mbps. Based on the LMDS spectrum and 5-fold reuse, the service capacity would be 10000 to 75000 simultaneously , symmetrical T1 circuits (1.5 Mbps) per communication payload.

CONCLUSION

Finally I conclude that the HALO aircraft can be thought of as a very tall tower or very low altitude satellite. Contracted to terrestrial broadband networks, the HALO Network offers ubiquitous, anyone-to-anyone broadband linkages throughout the footprint. HALO networks can be introduced to highly promising markets around the world on a selective basis. "Continuous improvement" is a significant attribute of the HALO network. It enables Angel to meet the increasing expectations of present customers, and to open new markets requiring lesser capability by re-assigning earlier-generation hubs
Thus the technology has a mid range of utilities in the flied of aviation services like aircraft monitoring, air traffic management, weather report etc.
It also provides an opportunity for the passengers to access the internet at very high altitudes i.e airplanes & its other conventional service
The Airborne Internet is a proposed network in which all nodes would
be located in aircraft. 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.
