5G is not a thing. Or, specifically, not a single thing. There is a lot of pieces to 5G.

Currently many home wifi routers use 5G, but it is really low power stuff.

Then there is the 5G that the state wants to implement where they basically bathe the entire world in 1mm band radiation.

But the answer to your question is, no, the first step in 5G is straight to the ISP.
You even eliminate your own personal routers.
