I don't get how upload is suppose to work..
In the 90's satellite internet the upload was sent via phone line / ISDN.
Are we suppose to have powerful directional transmitters attached to our laptops?
Or do they intend for the Starlink internet to be distributed via regional ground stations and just fail to mention it?
- wtallis 7y agoInitially, there will need to be a lot of regional ground stations, but not because of any asymmetry in the connection. End user base stations will use a phased array antenna similar to what the satellites themselves use, though probably a bit smaller. Ground stations will be very important early on, because these satellites do not include the planned laser links for communication between each other, so they can only bounce signals between end users and ground stations.
