> The speeds are theoretical and plummet as spectrum utilization increases. If everybody replaced their xDSL/DOCSIS/FTTx connections with 4G/5G and utilized them the same, the speeds would be terrible. The provider A1 in Austria (around 45% marketshare for broadband) uses ADSL for most of its broadband lines, which is significantly slower than cable. A few years ago they merged with the largest wireless provider and now use hybrid-ADSL-LTE modems that use ADSL by default, but which automatically switch to LTE when higher bandwidths are required. In addition there are several wireless providers (and MVNOs) that sell data flatrates which are cheaper and faster than ADSL. E.g., I recently replaced my ADSL connection with a LTE flatrate for 20 EUR a month that allows 20mbit down and 6mbit up (and almost all of the time it also reaches that speed). I often hear the argument that LTE would be too congested if everyone uses it. But I can't see any evidence of that in places where LTE is heavily used.
