INTRODUCTION
Wireless communication is simply data communication without the use of landlines.
This may involve cellular telephone, radio etc.
The presentation discuss about High Altitude Airships, the “STRATELLITES”.
WHAT IS STRATELLITE?
A “STRATELLITE”(25 times larger than good year blimp) is high altitude airship employed like a satellite for remote sensing, communication.STRATELLITES are positioned in stratosphere approximately 13 miles above the earth.
4th GENERATION
Since from the beginning of wireless communication, there have been a numbers of developments.
Considering the future generation of wireless communication i.e 4G cellular system.
4G is intended to provide high speed , high capacity and low cost
CONSTRUCTION OF STRATELLITE
The initial stratellite was 188 feet long, 60 feet wide & 42 feet high.
The outside layer is made out of a high-tech material called SPECTRA
Inside layer is filled with helium gas it is an inert gas and is therefore not flammable
With this design, the helium expands as the airship rises forcing air out by propellers and lifting the airship.
ADVANTAGES
Stratellites will carry over 20,000 pounds of radars and other equipments and communication relays.
Stratellites are planned to remain on station for a year at a time.
Stratellites are far cheaper to launch and to maintain.
For country two stratellites are enough instead of using thousands of towers.
CONCLUSION
STRATELLITES Provide the required facilities of wireless communication more efficiently than the ordinary towers. They minimise the cost of communication.
