Project Loon is a network of balloons travelling on the edge of space, to connect people in remote & rural areas & to help people back online after disasters. This is a project by Google. Much of the world’s population doesn’t yet have access to net & many projects are going on across the world to help people connect. Mobile internet played a key role in bridging this divide. Over 2.7 billion people are using the internet in 2013
Project Loon balloons float in the stratosphere. The balloons travel at 20 km above the earth surface in the stratosphere. Winds carry the balloons and they can move up or down depending on the wind direction. People can connect to the balloon network using a special Internet antenna. This will be attached to their building. The signal bounces from balloon to balloon, then to the global Internet back on Earth.
Sophisticated softwares are used to determine how the balloons should move to move with the wind to form a communication network. Project Loon currently uses ISM bands to communicate. Project Loon has started in June 2013 with an experimental pilot project in Christchurch and Canterbury, New Zealand. The link to Project Loon Google+ page
