Elon Musk says on Twitter that Starlink's internet speed will double this year to 300 Mbit per second.
Starlink is a project by space company SpaceX, in which broadband internet is offered from space via satellites.
Starlink is currently still in a testing phase.
Only interested Americans and Canadians can order a beta kit at this stage.
They are promised a speed of between 50 and 150 Mbit per second for a monthly fee of 99 dollars (82 euros).
On average, the download speed of Americans is about 71.3 Mbit per second, calculated the British internet provider Cable.co.uk on the basis of hundreds of speed tests in the past year.
In the Netherlands, that average speed is 95.6 Mbit per second.
Yet it is already possible to achieve speeds of a gigabit per second (1,000 Mbps) via fiber.
A delay of 20 ms to 40 ms can still occur in the Starlink connection in the current phase.
According to Musk, that delay will drop below 20ms later this year.
Musk also says Starlink should cover "most of the Earth" by the end of this year.
Next year, that coverage will be strengthened.
“Mobile networks always have an advantage in densely populated areas,” he writes.
"Satellites work best for areas of low to medium population density."
