3. INTRODUCTION SHIBATA ET AL In Japan , 2009 proposed new
ballooned wireless mesh network system for disaster. SPACE DATA
INC. Widens cellular network coverages, and provide private
network. GOOGLE THE PROJECT LOON
4. WHAT IS PROJECT LOON ?
5. THE PILOT TEST Project Loon start in june 2013. 30 balloons
, launched from New Zealands South Island. Pilot testers will be
used to refine the technology.
6. THE TECHNOLOGY Project Loon balloons float in the
stratosphere as twice as high as airplanes and the weather. They
are carried around the Earth by winds and they can be steered by
rising or descending to an altitude with winds moving in the
desired direction. People connect to the balloon network using a
special internet antenna attached to their building. The signal
bounces from balloons to balloons then to the global internet back
on earth.
7. HOW LOON MOVES Winds in the stratosphere are generally
steady and slow-moving at between 5 and 20 mph and each layer of
wind varies in direction. Project Loon users software algorithms to
determine where its balloons need to go, then moves each one into a
layer of a wind blowing in the right direction . By moving the wind
,the balloons can be arranged to form one large communications
network.

9. Envelope Solar panels Equipment DESIGNING OF LOON
10. ENVELOPE Envelope are made from sheets of polyethylene
plastic. A parachute attached to the top of the envelope. SOLAR
PANELS Each units electronics are powered by an array of solar
panels that sits between the envelope and the hardware. In full sun
, these panels produce 100 Watts of power enough to keep the
running while also charging a battery for use at night. EQUIPMENT A
small box containing the balloons electronic equipment. Radio
antennas to communicate with other balloons and with internet
antennas as the ground.
11. HOW LOON CONNECTS Three radio transceivers
Balloon-to-balloon communication. Balloon-to-ground communication.
The balloons use antennas equipped with specialized radio frequency
technology. Project Loon currently uses ISM bands that are
available for anyone to use.

15. ISM BANDS The industrial , scientific and medical (ISM)
radio bands. Radio bands reserved internationally for the use of
radio frequency (FR) energy for industrial scientific and medical
purpose other than communications.
16. ADVANTAGES Easy to use. Speed Increasing internet
usage.
