How about manoeuvring the balloons by adjusting their altitude to float to a wind layer after identifying the wind layer with the desired speed and direction using wind data. And the users of the service connect to the balloon network using a special Internet antenna attached to their building.
The signal travels through the balloon network from balloon to balloon, then to a ground-based station connected to an Internet service provider (ISP), then on to 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.
Mission Statement of Project: Balloon-powered Internet for everyone
Project Loon began in June 2013 with an experimental pilot in New Zealand, where a small group of Project Loon pioneers tested Loon technology. Wind data is taken from from the National Oceanic and Atmospheric Administration (NOAA). The results of the pilot test, as well as subsequent tests in the U.S. and Brazil, are being used to improve the technology in preparation for the next stages of the project.
These balloons fly at the height of 60,000 feet and can stay up in the air for as long as 100 days.
Noteworthy point is currently Google is not an Internet Service Provider. Google has reportedly received data from antennas on the balloons at a rate of 22 megabits per second. The balloons provide wireless Internet using the same LTE protocol used by cellular devices. Definitely this Google’s Project Loon is better use of technology & competence.
