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

AMENDED CLAIMS[received by the International Bureau on 15 April 1999 (15.04.99); original claims 1-35 replaced by amended claims 1-22 (6 pages)]
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.
