Everything about The Project Loon
What is Project Loon?
Google shocked the tech world by announcing a massive reorganization creating a parent company called Alphabet. In the shake-up, one of the divisions that became its own company is Google X, the secretive-ish lab that's devoted to experimental projects like driverless cars, artificial intelligence, and delivery drones.
Google X is also home to Project Loon, an effort to use high-altitude balloons to deliver internet in rural areas, or places where accessing the web is difficult.Google unveiled Loon in 2013, but the company had been working on it for at least two years before the company debuted it publicly.
The goal of Project Loon is to provide internet to remote parts of the world.
How it works?
Project Loon uses a network of solar-powered balloons flying at high altitudes to broadcast broadband to areas that don't have internet access.
Project Loon balloons fly between 60,000 and 90,000 feet about two to three times as high as most commercial airplanes. So these balloons float in the stratosphere which is miles over the earth to provide internet services.
The gas-filled part of the balloon is made of plastic, and when it's inflated, it's about 40 feet long.Loon balloons are solar-powered and have rechargeable batteries so they can operate at night. They are also equipped with GPS and weather monitoring equipment.The balloons use LTE signals so people with smartphones and other LTE devices can get online.
Signal and Accessibilty
On the Project Loon website, Google says that the speed of the service will be "comparable to 3G," which means it's fast enough to access your email on surf the web, but you wouldn't want to use it to stream Netflix or high quality video.
The LTE signal is sent up from ground stations to the network of Loon balloons, and then from the balloons to the ground.
Google says that one balloon can cover a roughly 25 mile in diameter area on the ground, and that "hundreds of people can connect to each balloon at once."
When you access the web through a signal from a Loon balloon, the traffic is relayed from the ground, back up to the network of balloons, and then back down to a ground station, where, according to Google, "it connects to pre-existing Internet infrastructure." Antennas attached to buildings can also receive the LTE signals from Loon balloons.
Direction Handling :Google steers the balloons go by changing altitude.The direction of wind varies with altitude, so Google controls the direction of the balloons by lowering them or raising them.
Disadvantages: When Google first started testing Loon, small leaks in the balloons would cause them to come down after a hours or few days. But Google says that it can stay up for more than 100 days at a time.
