Project Loon

More than half of the world’s population is still without internet access. Project loon is a research project developed by in Google X, to provide internet access to remote and rural areas. This project uses high-altitude air balloons, which are kept in sky (stratosphere) about 30 km high from ground to create wireless network with up to 4g-LTE speeds.

The project loon balloons are carried around by winds and there movement can be controlled by increasing or decreasing altitude with wind moving in desired direction. People connect to the network using special antenna attached to there house. The signal bounces from project balloon to balloon, which then provides connection back to earth. The unofficial development of the project began in 2011 in Google X. Later in 2013 this project was officially launched.

Project loon balloons used software  to determine where the balloon needs to travel, then moves  in the right direction. By moving with the flow of wind, the balloons can becombined to form larger communication network. Project loon balloons travel about 20 km above the earth’s surface in the stratosphere each layer in sky varies in speed and direction.

Balloons are super pressure, which enable them to stay for more than 100 days and are entirely solar powered. The signal travels through the balloons network from balloon to balloon, then to a ground-based station connected to an Internet service provider (ISP), then onto the global Internet. The system aims to bring Internet access to remote and rural areas poorly served by existing provisions, and to improve communication during natural disasters to affected regions.
