  coverage.jpg (59117 bytes) Sky Station's platforms are ideally suited to delivering a variety of wireless telecommunications services.

Located in the stratosphere 21Km (70,000 feet) above the earth, each platform acts as the highest tower in town, providing high density, high capacity, high speed service with low power requirements and no latency to an entire metropolitan and suburban area extending out into rural areas. No other existing or proposed technology offers this combination of high density service and low cost.

Subscribers transmit directly to the platform, where on board switching routes traffic directly to other Sky Station subscribers within the same platform coverage area. Traffic destined for subscribers outside the platform coverage area is routed through ground stations to the public networks or to other platforms serving nearby cities.

The Sky Station Advantage
There are several unique attributes that allow Sky Station to offer a broad array of services with low operating costs:

  • Sky Station platforms do not require a launch vehicle, they can move under their own power throughout the world or remain stationary, and they can be brought down to earth, refurbished and re-deployed without service interruption.
  • Once a platform is in position, it can immediately begin delivering service to its service area without the need to deploy a global infrastructure or constellation of platforms to operate.
  • The altitude enables the Sky Station system to provide a higher frequency reuse and thus higher capacity than other wireless systems.
  • The inexpensive platform and gateway stations make it the lowest cost wireless infrastructure per subscriber conceived to date.
  • Joint venture companies and government authorities located in each country will control the Sky Station platforms serving their region to ensure the best service offerings tailored to the local market. Offerings can change as a region develops.
  • Sky Station platforms are environmentally friendly. They are powered by solar technology and non-polluting fuel cells.
  • The 21Km altitude provides subscribers with short paths through the atmosphere and unobstructed line-of-sight to the platform.
  • With small antennas and low power requirements, the Sky Station system allows for a wide variety of fixed and portable user terminals to meet almost any service need.

The capabilities and low cost of the Sky Station system will revolutionize telecommunications.

Mobile Solutions
The ability to communicate anywhere, anytime is an integral part of today's global culture. A worldwide standard (3rd Generation Wireless or IMT-2000) is the next significant advance in a broadband wireless service for mobile, portable and fixed users. The STS system is the ideal means for low-cost rapid deployment of mobile services and Sky Station is participating in the development and delivery of 3rd Generation (3G) cellular service. Sky Station customers will use standard off-the-shelf 3G handsets.

A Big Pipe into Every Home
Today's telecommunications networks have become stressed by the explosive growth of the Internet. As more users tie up lines for longer periods of time, the usage patterns for which the networks were originally designed have been fundamentally altered. Consumers have become increasingly dissatisfied with the slow speed of dial-up access and are demanding higher speed solutions. Sky Station satisfies this demand by delivering personal T1/E1 broadband service to the mass market at a lower cost than existing or announced alternatives.

With data rates bursting to 2Mbps uplink and 10Mbps downlink, subscribers enjoy high speed Internet browsing and hosting, as well as other broadband services such as video conferencing.

Spectrum in the 47GHz band has already been designated globally by the International Telecommunications Union (ITU) as well as the Federal Communications Commission (FCC) for use by high-altitude stratospheric platforms, paving the way for planned commercial service to commence in the year 2005.

Wide Area Public Wireless LAN Solution
WLAN, or Wi-Fi (wireless fidelity) based broadband wireless networks have been the hottest technology story of 2002/2003. Companies such as Intel, IBM, AT&T Wireless, Boingo, NTT, etc. have raced to build public Wi-Fi "hot spots" in major metropolitan areas. Because they are based on standards, Wi-Fi equipments are orders of magnitude cheaper  than comparable proprietary technologies and sport  data throughputs ranging from 1 megabit per second (Mbps) to 54 Mbps and higher. The main drawback of Wi-Fi is the very limited range (< 150 m outdoor), which in essence excludes ubiquitous public Wi-Fi coverage. Another issue with Wi-Fi is that it operates within unlicensed bands, so interferences from other Wi-Fi or industrial equipments will be increasingly more difficult to avoid, which may ultimately limit its growth.

With its high gain (> 37 dBi) multi-beam phased array antenna, Sky Station can provide wide area ubiquitous public Wi-Fi service. Because of its small beam diameter, and its Fast Realtime On Demand Beam Allocation (FRODBA), Sky Station can provide high-speed wireless Internet and data services anywhere, anytime, without interferring with other equipmenets operating in the same bands. WIth Sky Station's Public Wi-Fi service, customers can get connected anywhere within Sky Station's vast footprint of 560 km diameter coverage, and not be restricted to just a few isolated Wi-Fi hot spots. It is literally, the "biggest Wi-Fi switch in Sky"!

Telephony for the Developing World
All developing nations need low cost access to high density telecommunications links to support accelerated economic development and inclusion in the Information Revolution. Sky Station's stratospheric platforms provide the fastest, easiest and least expensive way to bring advanced services to the developing world. One Sky Station platform alone provides telephone service for millions of subscribers at a lower cost than any current or proposed system.

Wireless High-Speed Backbone Services
Optically linked Sky Station platforms could transmit voice, data, and video at speeds and volumes comparable to fiber optic cable (terabits per second) and provide a wireless backbone telecommunications link between metropolitan areas, countries and continents. Sky Station is seeking global regulatory approval for this service on its airships.

Satellite Concentrator/Repeater Services
Satellite TV broadcasting has been another hot story of 2002 and is enjoying a healthy growth in 2003. However, after having traveled 36,000 km to reach earth, the satellite TV signals become so weak that they require large (20 inch in diameter or so) satellite dish antennas precisely aligned so as to point exactly at the satellite in order to provide acceptable TV reception. For two-way data services, even larger and more accurately aligned satellite antennas are needed, since only such large antennas can focus the signal to narrow-enough beams to avoid interference from/to adjacent geo-synchronous satellites that are only 3 degrees apart!

At 21 km in altitude, Sky Station platform is far above any man-made radio noise, thus any satellite TV signal can be received with great clarity using Sky Station's built-in high gain satllite antenna. The received satellite signal is then re-amplified and re-broadcasted using beam-shaping antennas to ensure almost uniform signal strength across a coverage area of 300 km in radius. Subscribers within this coverage area can received satellite TV signals using portable satellite TV receivers with 4-in diameter ultra-small patch/dish antennas.

Sky Station can also improve two-way satellite data service because its multi-beam data delivery technology allows the same spectrum to be reused multiple times within even a medium size city. This will enable satellite operators to serve hundreds of time more customers within a given metropolitan area. By contrast, a satellite beam is typically larger than even the largest metropolitan area, hence only a fraction of the alloted spectrum can be used within any metroplitan area., thus limiting its capacity to service major cities where most customers reside. Another benefit Sky Station can provide to satellite operators is to enable the digital satellite signals, whether it be one-way TV signal, or 2-way data/voice/multimedia signals, to interconnect with Sky Station's own 3G and/or public Wi-Fi networks to reach an even broader audience.
