Halo's data-relay equipment will provide a footprint of 50 to 75 miles for high-speed (up to 25 megabits per second) voice and data transmissions from its cruising altitude of 50,000ft. Signals will be stronger than those beamed from low-earth satellites, and will not be blocked by buildings and mountains, as is the case with transmissions from towers. Diamandis said that costs were lower than using satellites. One hundred planes could be built for $700m (pounds 412m). The cost of launching the Iridium satellite network was $4.4bn (pounds 2.6bn).
By bypassing existing fibre-based communications networks, which charge access fees, Angel intends to deliver high-speed, low-cost communications, starting in Los Angeles in the year 2000.Reuse content
