Balloon Design - Google Project Loon


As Google has launched Project Loon in New Zealand as part of pilot testing, all around the world is looking forward to their massive support to the Internet World. Just imagine "when we are at dense forest also, we can access internet" it will be an awesome moment. Google's project loon's technology can be used to avoid huge expensive fiber cables that are installed underground between countries to allow users to access Internet. In Indian rural areas we are not getting proper mobile network coverage of most of the well developed providers. Whole rural area is looking forward to get high speed Internet from Google. Google feels that this will greatly increase the usage of internet in rural areas of the world where the country can't afford to lay underground fiber cables.

Technology Used In Google Loon


The high altitude balloons floated on the stratosphere fly over the world. Mostly in the east west direction as they are parallel with lines of latitude. Solar panels attached to the balloon will generate enough electricity in just four hours. That electricity will be enough to need for the transmitter on a day to beam down the internet signals to the ground stations. These stations are located almost 100 km apart and these stations will transmit or bounce the signals to other relay balloons that will send the signals back-down.

Google is claiming that using this technology, the users having the receivers with the range of balloons will get Internet, with speed comparable to 3G. As Google is using unlicensed 2.4 and 5.8 GHz ISM Bands. But still their first pilot testing is not as much successful as Google Thought, and only after some more pilot testing, we will get know about how we can rely on this Google balloons.


Equipment Design Of Google Loon Project


The balloon envelope used in the project are made by Raven AeroStar. Balloon envelope is the name and main part for inflatable part of the Balloon. Envelope is made up of Polythene plastic about 0.076mm thick, filled with helium. Balloon is 15m (fifteen meter) wide by 12m (twelve meters) tall when fully aired. Balloons are made for use in super-pressure balloons, which are long lasting by the help of high pressure from air inside when floated on the high altitude.

A Small Box weighing around 10Kg is hanged under the inflated envelope. Which includes balloon's electronic equipment. This box contains Circuit Boards, Radio Antenna, Batteries. Circuit Boards are used to control the over all activity of the balloon. Radio Antenna is used to communicate with other balloons and the receivers on the ground. Batteries for storing solar power, so that balloons can also work during nights.

Solar Panels are the another important part in the Google Balloon. Each Unit's electronics are powered by an array of solar panels. In full Sun this solar panels can produce 100 Watts of power, that is enough to keep the balloon working during day time as well as charging batteries for the night time.
