Transcript of Copy of PROJECT LOON

LOON ANTENNA
Balloons doesn't stay in fixed orientation.
Antennas on Balloon are polarized.
Two antennas are present in the case.
one to revcieve direct signal.
Can emit and receive radio signals.
INTRODUCTION
Two-third of world population.
Project loon is network of loons travel in outer space.
To connect people in rural and remote areas.
These loons move in stratosphere at a height of 64,000 feet above ground.
The pilot project started in 2013 by Google.

Loon Technology
Project loon balloons float in stratosphere.
There are many layers of wind.
Loon balloons go to the specified altitude with the direction of the wind.
Special loon antenna are designed.
Internet speed data upto 3G.
ISM band width 2.4 and 5.8 GHz
HOW LOON MOVES ?
wind moves at different directions at different heights in different directions.
"Cruce" mechanism to navigate through atmosphere.
Uses wind data from metereological departments.
mostly wind moves from east to west.
wind velocities range from 5-24 MPH.

Envelope made up of polyethylene of 0.076 thickness.
Can with stand super pressures and temperature of -70 Degrees F and 1/100 of atmospheric pressure.
How loon connects ?
Each loon can provide connectivity to 40km in diameter with speed ranging upto 3G.
Three radio tranceievers
balloon - balloon communication.
balloon-ground communication.
Third for backup.
loons use specialized radio frequency tehnology.
Loon uses ISM Bands of 2.4 and 5.8 GHz.
ADVANTAGES:

Global access of internet is made easy.
Internet speed ranging upto 3G.
Can be accessed even during natural disasters.
less economical and more feasible.
