Starlink satellite internet

Elon Musk's Starlink satellite Internet is an incredible step on the path to technological independence of mankind. SpaceX-a rocket that was launched back in May 2019 with a huge payload weight, marked the beginning of the launch of sixty two-hundred-kilogram satellites into Earth orbit. In the future, they will become part of the unprecedented global Starlink network being created. According to the inventor's idea, in the next few years it is planned to launch a total of 12.000 flying objects that will provide users with the opportunity to connect to the Internet anywhere in the world.


Companies that strive to provide users with fast access to the network.


In fact, the idea of an all-planet Internet is not new. A number of corporations are already developing and trying to use technologies that should make a revolutionary leap in the future. The only question is which of them will have time to make them a reality. In addition to SpaceX, Amazon engineers are ready to launch about 3,000 satellites. Rick Branson and OneWeb are ready to start a project to deploy a network of about 600 flying objects. New information technologies can make the Internet faster and more powerful, providing a delay in data transmission of about 30 milliseconds, and this can already be compared with DSL systems. The information giant Google is not far behind in development, however, the experiment with balloons did not give the expected results. FaceBook and Airbus plan to distribute the Internet by installing repeaters on aircraft.

Elon Musk is significantly ahead of his closest competitors, because by the end of 2020, he plans to put almost 1.000 satellites into Earth orbit. His rivals are far from this milestone.


How Starlink works.


In fact, Elon Musk is just refining the existing system. In the world, only a few providers can provide users with Internet access by satellite connection. In order for the technology to work, a transceiver is used (a device for receiving and transmitting satellite signals). In fact, this is the same router, only working on a global scale.

Why can't existing satellite systems be used to transmit high-speed Internet? The point is that the orbiting aircraft are located at an altitude of 36.000 km, and Elon Musk's satellites will fly at a distance of 300 to 1.400 km from the surface and "communicate" with ground stations that transmit information messages to orbit using radio waves. The satellites themselves will exchange data with each other using a laser.


Reasons for the need for a global satellite network.


The UN report mentions that at the beginning of 2019, only half of the world's population has high-speed access to the network. In Europe, 80% of residents have a broadband connection, and only 20% of Africans have it. Due to the complexity of laying fiber and the economic unprofitability of these works, in some areas of poor countries, many people do not have access to the network at all.

Experts believe that by 2025, most of the world's inhabitants will be able to access the Internet using broadband. Analysts believe that over 3 billion people will have open access to various services that they previously had no opportunity to connect to. Accordingly, these will double the volume of markets: online stores, educational and information platforms, social media.
