Internet giants continue to invest in expanding their spheres of influence by designing airborne Internet repeater systems. In particular, Facebook has relied on a network of laser drones. Google also has its own "unmanned" project, many of the details of which are still kept secret. It is only known that it will be a whole fleet of giant balloons-repeaters capable of providing the Internet for 57% of the world's inhabitants who are still offline.
Currently, Facebook is implementing a project to create a drone Aquila 1. Construction of the first instance was completed recently in Somerset, England. It is a giant flying wing, 43 meters wide, which is slightly larger than that of the Boeing 737.
Aquila 1 is made of a thin layer of foam covered with carbon fiber. The ability to fly will be provided by 4 "solar" engines. Each drone will spread the Internet over an area with a diameter of up to 160 km, staying in the air for three months. To maintain a high data transfer rate, information between the drones will be transmitted using a laser.
Google balloons - Project Loon have been surfing the Fifth Ocean since June 2013. While these are test flights. The balloon flight is regulated by pumping / pumping helium from a sealed bag fixed inside the outer shell of the balloon. This allows the balloon to descend or rise depending on the desired wind direction.
A grouping of balloons will be able to stay in the air for up to 150 days, and each balloon will move in a certain sequence, covering the distribution of the Internet within a radius of 80 km.
