INTRODUCTION

o Wireless communication is simply data
communication without the use of landlines. This may
involve cellular telephone, two -way radio, fixed
wireless (broadband wireless), laser (free space
optics) or satellite communication systems.
o Since from the beginning of wireless
communications, there have been a number of
developments in each generation. Considering the
future generation of wireless
communication L.e.: 5G.

oStratelites provide the required facilities of wireless
communication more efficiently than the ordinary
towers.
o The Stratellite will allow subscribers to easily
communicate in 'both directions' using readily
available wireless technology.“
oThey minimise the cost of communication.

EXISTING TECHNOLOGY(SATELLITE)
5
• Satellite is an artificial object which has been intentionally placed into
higher orbits.
• Satellite communication is the backbone of wireless communications, and
global positioning systems.
• Satellite in orbit of the planet cover huge footprint territories
• Satellites come in 4 types:
I. Geo-stationary
II. Sun-synchronous
III. Geosynchronous
IV. Low-earth orbit

STRATELLITE
• A stratellite is similar to a satellite, but is stationed in the
stratosphere rather than on the orbit.
• Stratellite is a "High Altitude Airship(HAA)", which is positioned
approximately 13 miles(20KM) above the earth, which
provides the benefits of a satellite like remote sensing,
navigation and communication.

• 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.
• The Stratellite is designed to carry certain payloads into
the Stratosphere determined by the requirements of the
customer as.
• A single unit could send broadband, mobile phone and
digital television and radio signals to a large area. The
'unmanned' Stratellite would be powered by solar cells
and propelled by electric motors.

WORKING
Inside is filled with Helium gas, as it is inert gas not
flammable.
• The Helium gas expands pushing out air and lifting the
airship.
• Uses solar cells sprayed on their surface to generate
electricity.
• The generated electricity drives propellers that work with
GPS technology to keep the stratellite stationary.

STRATELLITES FROM SATELLITES
• Sans wire Inc were the first to come up with the Stratellite. As the
name suggests, it is a satellite, in the stratosphere. Positioned 13
miles, or 20 kilometers above the surface of the earth, it has the
straight up-and-down communications advantages of any other
satellite, but reduces transmission times by a factor of nearly 2000 for
geostationary satellites, and 15 for low orbiting satellites.
• Using airship technology, a stratellite is above the cloud layers and so
can be powered by solar cells and propelled by electric motors which
are designed to keep the craft at a single, pre-programmed 3-axis
GPS co-ordinate, and check with higher satellites that it stays in that
position.

• Launching costs are next to nothing, and at nearly 250 feet
long, they have enough lift for sophisticated computation
equipment - more than most conventional satellites
• Placing a communications platform into the stratosphere, in
the form of an airship, has never been done before. Such a
platform can fundamentally change how the world delivers
wireless telecommunications and the way we as individuals
communicate.

ADVANTAGES
• D ecreases Signal lat ency
• Less expensive t o launch
• Service an area of 300,000 square - miles
• Tw o w ay high speed dat a communicat ion
• H igh speed broad - band a c c e s s e ve n in remot e area.
• For a country tw o stratellites are enoughinstead of
t housands of t ow ers

• Stratellites will carry over 20,000 pounds of
radars and other remote imaging
equipment, navigational aids, and
telecommunications relays.
• Stratellites are planned to remain on station
for a year at a time and will cost a one fifth
as much as a comparable satellite

DISADVANTAGES
• May lead to traffic problems in stratosphere.
• Would require efficient ground control and
maintenance.
• So far, this technology remains non-commercialized,
and is in a prototype stage for further developments.
• Unlike with a satellite, a stratellite is at the mercy
of the weather.

CONCLUSION
• Probably the most "far out there" concept in this
roundup, Stratellite isactually much closer to reality
than what you may think.
• Once the defects of Stratellites have been overcome
and become morereliable, they play a vital role in
the future generation wireless communication.
• This is a promising technology that could combine
the best of Satelliteand wired Internet - fast with low
latency and hugely widespread, atleast in theory.
