The document describes The Halo Network, a proposed broadband wireless metropolitan area network. The key aspects are: - It uses a high-altitude aircraft called HAAPS operating at 16km to serve as an airborne hub/central node for a star topology network. - The HAAPS aircraft houses an antenna array to create hundreds of virtual cells on the ground to provide service to thousands of users within a 100km radius area. - It claims advantages over terrestrial and satellite networks like rapid deployment, high signal quality, availability and bandwidth, and lower costs.

18. Advantages

19. Rapid BuildoutA HALO Network can be put into operation within weeks. Upon network activation, it provides service to the full super metropolitan area.

20. High Signal Quality and AvailabilityAt frequencies above 20 GHz, where wireless broadband services are being licensed, high losses of signals are caused by ground terrain, foliage and rain. The high viewing angles to HALO aircraft (20 degrees or greater) assure signal paths free of absorbing objects. The combination of a large aperture and high signal power utilized by the HALO Network allows service availability in regions with high rainfall rates.

21. High BandwidthThe initial capacity of the network will be on the scale of 10 Gb/s, with growth beyond 100 Gb/s. This enables services including but not limited to T1 access, ISDN access, Web browsing, high-resolution videoconferencing, large file transfers, offsite training and Ethernet LAN bridging.

22. Low CostNegligible ground infrastructure, coupled with a large footprint and multi-megabit-per-second data rates make it extremely competitive on a $/bit/square mile basis.

23. Advantages Over Terrestrial NetworksDoes not require complex geometries involving many base stations interlinked by cabling or microwaves.Unlike terrestrial networks, reengineering of the entire satellite network may not be required to increase the system capacity.Unlike terrestrial networks, reengineering of the entire satellite network may not be required to increase the system capacity.

27. Unlike satellite systems, which are multi-billion dollar investments, the HALO Network can be financed one market at a time, which makes it more suitable for developing countries.The HALO aircraft is 10 to 1,000 times closer to the user than a satellite, with 10 times the available electrical power. Consequently, the HALO Network can allocate significant capacity directly to densely populated regions.The HALO aircraft is 10 to 1,000 times closer to the user than a satellite, with 10 times the available electrical power.
