Baris Erkmen (reported the successful launch of a laser communication system in Africa on the Congo River. It is reported that
This is not Alphabet's first attempt to make the Internetmore accessible. In January 2021, the holding closed its previous Project Loon initiative. She became famous for developing a system for providing Internet access using helium balloons. Despite the failure of the project, engineers continued to develop some technologies that appeared during its implementation. One of them was free space optical communications (FSOC - Free Space Optical Communications). She which provided communication with balls at high altitude using lasers.
FSOC technology is a wireless analogue of fiber optic lines, and in the line of sight, it allows you to establish communication at speeds of more than 20 Gbps.
Almost three weeks via laser communication channelmanaged to transfer about 700 TB of data. The system was tested between Brazzaville in the Republic of the Congo and Kinshasa in the Democratic Republic of the Congo. Communication was carried out across the river using lasers. This territory in Africa was chosen not so much because of the difficult climatic conditions of the climate, but because of the deep and fast river. Despite the fact that the cities are located at a short distance from each other - several kilometers in a straight line, a fiber optic connection would require about 400 km of cable.
