Launching in the middle of the last decade, the initiative 50x15, AMD is hoping to provide half of the world population means of access to the global network by 2015. Another global initiative, OLPC, planned to provide each student a laptop for $ 100, but then interest in this form factor began to fade. Of course, the student OLPC computers are available so far, but many of them are tablets, and they are distributed on subsidy basis , as the cost of each exceeds those same $ 100.
You would think that all the global initiatives are doomed to failure. However, Google will by the end of next year expects to launch commercial service network of balloons in the framework of Loon, which will provide access to global information resources of the inhabitants of vast areas with poor terrestrial communications infrastructure.
To begin with, that was created by the Google system for semi-automatic launch balloons carrying telecommunications equipment. Conventionally designated , it allows you to run a balloon by the four persons every 15 minutes at a wind speed of 24 meters per hour. Manual Start required 45 minutes for each ball, and limited the allowable wind speed of 10 meters per hour. Special curtains protect executable ball from the wind and the guides help to stabilize its position at startup. This setup greatly facilitate the work of personnel at the stage of commercial operation .
The second major innovation - is to increase the distance that each ball is able to transmit the signal wirelessly. If before the ball could not be removed from a ground base station at a distance of 80 km, it is now the communication system between the neighboring balls allows a signal to the relay distance of 400 to 800 km. However, the problem greatly complicates the DC offset balls air masses. These features allow to cover the entire western part of Africa, just eight terrestrial base stations. By the end of this year, Google hopes to launch air network in trial operation for a few days, and a year expects to begin commercial operation in the regions of Africa, Southeast Asia and Latin America.
