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.
