As my question before was a bit weird (no definite answer could be given), I try it to formulate my question differently:
When comparing these two options:
30-40 Mbit/s download speed (LTE), but with a wireless router. (speedtest said 31 Mbit/s) 20 Mbit/s download speed (DSL), with a wired router (4 GigEthernet Ports) (ISP says 20Mbit/s)
What shoud be considered when comparing these options? Is the first option (LTE with a wireless router) still better because of those 30-40Mbit/s download?
Credentials are speed and availability for 4-6 users.
I really just want to know how big of an impact the fact is, the LTE/WLAN is a shared medium and half duplex, so if those 30-40Mb/s (LTE, wireless) just seem to be better than those 20Mbit/s (DSL, wired).
EDIT: I want to know if the bandwidth difference between my two options above (which is around 10Mbit/s) is compensated by the fact, that the wireless router in my first option is half duplex and a shared medium and the router in my second option is not.
