Sanswire to demo Stratellites
Posted: 11-Jul-2004 [Source: Sanswire]

[Sanswire to demonstrate its high-altitude airship, the Stratellite(tm) designed for transmitting wireless communications from a stationary position at 65,000 feet. Proposed uses besides filling the last mile void include cellular, 3G/4G mobile, MMDS, paging, HDTV and others.]

Atlanta -- Sanswire Networks, LLC, a wholly-owned subsidiary of Globetel Communications Corp. announced the schedule for its demonstration of the wireless transmission capabilities of its Stratellites.

The live demonstration will be held at the Company's Atlanta headquarters on July 13 and 14, 2004. The Company plans to demonstrate how it will use Stratellites as high-altitude wireless transmission platforms. The demonstration will consist of a number of wireless tests using various IP products and services over different frequencies, all from a fixed position in the sky. Sanswire will hold the platform in one stationary position using GPS technology. A series of antennas will be mounted to the platform that will receive a wireless signal from an earth station and retransmit the live signal to a designated area on the ground, allowing the Company to demonstrate the voice, video, and data capabilities of the high-altitude wireless platform. Attendees will be able to make an international phone call, surf the Internet, and watch live television programming. The Company will also be demonstrating the surveillance capabilities of the Stratellite.

Subsequent to the communications demonstration, the Company will set a date for the next round of testing that will involve launching a Stratellite into the stratosphere and holding it in position at 65,000 feet.

A Stratellite is similar to a satellite, but is stationed in the stratosphere rather than in orbit. At an altitude of only 13 miles, each Stratellite will have clear line-of-site communications capability to an entire major metropolitan area as well as being able to provide coverage across major rural areas. Several Stratellites linked together could cover many hundreds of thousands of square miles. The Stratellite will allow subscribers to easily communicate in "both directions" using readily available wireless devices.

In addition to voice and data, proposed telecommunications uses include cellular, 3G/4G mobile, MMDS, paging, fixed wireless telephony, HDTV, real-time surveillance and others.

What is a Stratellite(tm)?

A Stratellite is a high-altitude airship that when in place in the stratosphere will provide a stationary platform for transmitting various types of wireless communications services currently transmitted from cell towers and satellites. It is not a balloon or a blimp. It is a high-altitude airship.

Made of Spectra and powered by solar powered electrical engines, each Stratellite will reach its final altitude by utilizing a helium and nitrogen filled double envelope. Once in place at 65,000 feet (approx. 13 miles) and safely above the jet stream, each Stratellite will remain in one GPS coordinate, providing the ideal wireless transmission platform. The Stratellites are unmanned airships and will be monitored from the Company's Operation Centers on the ground.

A Stratellite will have a payload capacity of several thousand pounds and clear line-of-site to approximately 300,000 square miles, an area roughly the size of Texas. However, the Company's initial plan is to use one Stratellite for each major metropolitan area.

The Stratellite is similar to a satellite in concept, but is stationed in the stratosphere rather than in orbit. Existing satellites provide easy "download" capabilities, but because of their high altitude are not practical for commercially viable "two-way" high-speed data communication. The Stratellite will allow subscribers to easily communicate in "both directions" using readily available wireless devices.

Once the National Wireless Broadband Network is completed, Sanswire will be able to provide voice, video, and broadband Internet access to all parts of the country.

Our subscribers will be able to sit in their home on a laptop computer while connected to the Internet at high-speed. If they need to go to the office or across town, they simply close the laptop and take off. When they get to their destination, they open their laptop and they are still on the Internet. If they need to travel to another city, they simply take their laptop with them and when they get to where they are going, they open their laptop again and they are still connected. No more finding local access numbers. No more tying up phone lines. No more modem hassles. And more importantly, no more slow speeds.

Once this platform is completed, content providers of all kinds that are interested in reaching our subscribers may do so without the existing concerns of the last mile void.

In addition to Sanswire's National Wireless Broadband Network, proposed telecommunications uses include cellular, 3G/4G mobile, MMDS, paging, fixed wireless telephony, HDTV and others.
