  • Space Internet OneWeb "dispersed" to 400 Mbit/s


    The British company OneWeb published the results of the first test of the space Internet. The connection was established with the help of previously launched low-orbit satellites, the grouping of which in the future will provide broadband Internet access anywhere in the world. The result was impressive even by the standards of some ground operators.

    During the test, the data transfer rate was recorded up to 400 Mbit/s, the signal delay rate was not more than 40 milliseconds. While the company has put into orbit only six satellites OneWeb F6, in the future it is planned to increase their grouping to several hundred. The tests were conducted in collaboration with Intellian, the developer and manufacturer of terminals for OneWeb users, and SatixFy, which developed a test modem to establish a connection. According to the head of OneWeb Adrian Shtekel, the company will begin to provide commercial access to the space Internet in the next 24 months.

    Since the 4th quarter of 2019, 30 satellites are planned to be put into orbit at the same time, by 2021 it is planned to create a structure of 650 satellites providing global access to the network. If there is increased demand, their number can be increased to 1980. Each of the satellites is able to provide communication with the Earth in the Ka-band (on radio frequencies 20-30 GHz) and Ku-band (11-14 GHz).

    According to OneWeb, users in the future can expect a stable connection at a speed of more than 100 Mbit/s (peak — up to 500 Mbit/s), with a delay time of 25-35 milliseconds. Existing geostationary satellite communication systems provide an average delay time of more than 300 milliseconds. A competitor to the British provider will be SpaceX, which has already put into orbit 60 satellites but has not yet published the results of their tests.
