  • 1. A SLIDE PRESENTATION ON HALO NETWORK Presented By FARHEEN NAAZ B111058
  • 2. CONTENTS          Introduction. Wireless Broadband Communication Market. Concept. Key Features. Service Area. Services. Architecture. Advantages. Conclusion.
  • 3.     The High Altitude Long Operation Network is a broadband wireless metropolitan area network, with a star topology, whose solitary hub is located in the atmosphere above the service area at an altitude higher than commercial airline traffic. The initial capacity of the network will be on the scale of 10 Gb/s, with growth beyond 100 Gb/s. The HALO/Proteus airplane is the central node of this network. It will fly at altitudes higher than 51,000 ft.
  • 4.     The HALO Network is capable of providing high rate communications to users of multimedia and broadband services. The feasibility of this approach is reasonably assured due to the convergence of technological advancements. These technologies are individually available, to a great extent, from commercial markets. The HALO™ Network seeks to integrate these various technologies into a service of high utility to small and medium businesses and other multimedia consumers at a reasonable cost.
  • 5.  "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". (Lou Gerstner, IBM, April 1997) The growth in use of the World Wide Web and electronic commerce will stimulate demand for broadband services.
  • 6.  There are various facts that show the strong interest in wireless communications in India:  50 million subscribers to wireless telephone service  28 million dollars annual revenue for wireless services  38,000 cell sites with 37 billion dollars cumulative capital investment  40% annual growth in customers  25 million personal computers sold each year  50 million PC users with Internet access
  • 7. High-Speed Data Links Transmitted Over Millimeter Wave Frequencies Provide Broadband Data Services to Various End-Users
  • 8.  The key features of the HALO Network are summarized below. 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 
  • 9.      Most metropolitan areas will fit within a signal "footprint" of 40-60 miles diameter. The following figure shows the coverage of a 50mile HALO™ Network service-area footprint for the New York City metropolitan area. Notice that "double coverage" of certain areas occurs due to overlapping adjacent footprints. This provides higher reliability links and reduces blocking factors on requests for service. The footprint over Manhattan covers 4.8 million households or 12.5 million people.
  • 10.  The HALO Network accommodates the following design objectives:  Seamless ubiquitous multimedia services  Adaptation to end user environments  Rapidly deployable to sites of opportunity  Bandwidth on demand for efficient use of available spectrum
  • 11. The HALO™ Network Architecture
  • 12.    The HALO network has several advantages over terrestrial wireless networks. The latter have complex geometries involving many base stations interlinked by cabling or microwaves. On the other hand, satellite networks require more expensive terminals with high power to achieve the same data rates possible through the HALO Network. The capacity of a satellite network can be increased, but at higher expense than the HALO Network, typically only by adding more satellites.
  • 13.    The HALO network will provide wireless broadband communication services. The feasibility of this network is assured due to a convergence of technological advancements. The HALO Network is predicated on the successful integration of these technologies to offer communications services of high quality and utility to small and medium-sized businesses at reasonable prices. While a variety of broadband access modalities are promising for the U.S. markets, the HALO Network may be a winner for "green field" deployment, especially in regions where the existing infrastructure is not amenable to an upgrade or retrofit.
