  2. 2. WHAT IS PROJECT LOON?  Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas. Raval Sneh 2
  3. 3. Raval Sneh 3
  4. 4. THE PILOT TEST  Project Loon starts in June 2013 with an experimental pilot in New Zealand. A small group of Project Loon pioneers will test the technology in Christchurch and Canterbury.  30 balloons, launched from New Zealand’s South Island.  The experience of these pilot testers will be used to refine the technology and shape the next phase of Project Loon.

  6. 6. THE TECHNOLOGY  Project Loon balloons float in the stratosphere, 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 balloon to balloon, then to the global Internet back on Earth. Raval Sneh 6
  7. 7. Stratosphere  Situated between 10 km and 60 km altitude on the edge of space.  Air pressure is 1% of that at sea level.  Thinner atmosphere offers less protection from the UV radiation and temperature caused by the sun’s rays. Raval Sneh 7
  8. 8. 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 uses software algorithms to determine where its balloons need to go, then moves each one into a layer of wind blowing in the right direction.  By moving with the wind, the balloons can be arranged to form one large communications network.

  10. 10. HOW LOON IS DESIGNED  ENVELOPE  SOLAR PANELS  EQUIPMENT Raval Sneh 10
  11. 11. Component  Solar panels  Envelop  Equipment Raval Sneh 11
  12. 12. ENVELOPE  Project Loon’s balloon envelopes are made from sheets of polyethylene plastic and stand fifteen meters wide by twelve meters tall when fully inflated.  A parachute attached to the top of the envelope allows for a controlled descent and landing whenever a balloon is ready to be taken out of service. Raval Sneh 12
  13. 13. SOLAR PANELS  Each unit’s 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 unit running while also charging a battery for use at night.  By moving with the wind and charging in the sun, Project Loon is able to power itself using only renewable energy sources. Raval Sneh 13
  14. 14. EQUIPMENT  A small box containing the balloon’s electronic equipment .  This box contains circuit boards that control the system .  Radio antennas to communicate with other balloons and with Internet antennas on the ground .  And batteries to store solar power so the balloons can operate during the night . Raval Sneh 14
  15. 15. HOW LOON CONNECTS  Each balloon can provide connectivity to a ground area about 40 km in diameter at speeds comparable to 3G.  Each balloon is equipped with a GPS for tracking its location Raval Sneh 15
  16. 16. HOW LOON CONNECTS  Three radio transceivers.  balloon-to-balloon communications.  balloon-to-ground communication.  third for backup.  The balloons use antennas equipped with specialized radio frequency technology.  Project Loon currently uses ISM bands that are available for anyone to use. Raval Sneh 16
  17. 17. Raval Sneh 17
  18. 18. ISM BANDS  The industrial, scientific and medical (ISM) radio bands .  Radio bands reserved internationally for the use of radio frequency (RF) energy for industrial, scientific and medical purposes other than communications. Raval Sneh 18
  19. 19. Advantages  Easy to use.  Speed.  Increasing Internet usage. Raval Sneh 19
  20. 20. Disadvantages  Cost.  Maintenance.  Balloon can work for few week only. Raval Sneh 20
