Samsung also wants to distribute the Internet through microsatellites
Samsung has already joined a rather large group of companies that are planning to organize Internet access for people from remote areas of the planet in one way or another. The scientific article, authored by the head of the research division of the South Korean company Faruk Khan (Farooq Khan) and which is titled very unusually - “Mobile Internet from Heaven” ( pdf ) - describes the concept of a fleet of 4,600 microsatellites that will be in low earth orbit provide data flow of 1 zetabyte per month. This bandwidth should be enough for 5 billion people all over the Earth, each of which can use 200 GB of traffic per month.
Technically, the idea of ​​Samsung does not look new. By microsatellites, Khan understands spacecraft weighing less than 500 kg, which will be located at an altitude of up to 2,000 km. Subscriber devices for receiving satellite signals should not be directly used: instead, a network of cellular stations, similar to that of existing mobile operators, is assumed on the surface of the Earth. It is from them that phones and tablets will receive the converted satellite signal. Based on 5G communications and the next generation of Wi-Fi, Samsung wants to develop some kind of common universal wireless technology for Internet access, which will be used by user devices. The technical parameters of such cellular stations, their number, and the cost of their facilities are not called. In addition, it is assumed that there will be control centers that will monitor the operation of microsatellites.
So far, Samsung’s competitors are ahead of the South Korean company for a similar idea of ​​accessing the Internet. SpaceX Ilona Mask has at least spacecraft that can deliver microsatellites to the required orbit. The British company OneWeb, which sets itself a task similar to Samsung, has already managed to conclude contracts for launching launch vehicles. True, their satellite fleet is significantly smaller than the one planned by Samsung - only 672 satellites. Also, Google and NASA are planning similar launches; In addition, the search giant in the arsenal has also Project Loon, the distribution of the Internet in which will be made using a system of balloons.
