Abstract
A communication system is provided in which an airborne atmospheric platform located in the Earth's atmosphere communicates with a network of satellites and with ground-based users. Because of its location in the atmosphere, the atmospheric platform takes advantages of previously unused high frequencies in communicating with the satellite network. The atmospheric platform communicates with ground-based users at a second, lower frequency.
Claims
1. A wireless communication system comprising: a plurality of ground-based users; at least one satellite travelling in an orbit around the Earth; and at least one manned heavier-than-air aircraft operating in the atmosphere at an altitude above said plurality of ground-based users, wherein -said manned .aircraft communicates via wireless signals with said at least one satellite and said ground-b.as.ed users.
2. The communication system of claim 1, wherein said manned aircraft ■communicates with said at 1-east one satellite utilizing a first frequency band and with said ground-based users through a second frequency band.
3. The communication system of claim 2, wherein said first frequency band is shifted higher than said second frequency band.
4. The communication system of claim 2, wherein said fir.st frequency band is greater than 50 GHz and said second frequency band is less than 50 GHz.
5. The communication .system of claim 2, wherein said first frequency band is greater than 60 GHz and said second frequency band is less than 60 GHz.
21
6. The communication system of claim 4, wherein said first frequency band
is less than 100 GHz.

24
18. A method for providing broadband communications to a plurality of ground-based users, comprising: providing at kast one satellite orbiting above the Earth; providing at least one airborne atmospheric platform capable of communicating with said at least one sateUite and said plurality of ground-based users; transmitting a first signal from .said at least one sateUite to said at least one atmospheric platform; and transmitting a second signal related to said first signal from said at least one atmospheric platform to at least one of said plurality of ground-based users.
19. An atmospheric platform for use in a communication system, said atmospheric platform providing a communication link between ground-based users and orbiting sateUites, wherein said atmospheric platform communicates with said sateUites at a first frequency band and said ground-based users at a second frequency band.
20. The atmospheric platform of claim 19, wherein said first frequency band is higher than said second frequency band.
21. The atmospheric platform of claim 20, wherein said first frequency band is less than 100 GHz.
