I searched online and lot of topics are about hotspot which I am not interested. since all hot stop slows down after a while. And then there are another set of topics that are about using Android's USB tethering to setup a PC (that itself is simple enough) but then there are some third topics about using PC that is using USB tethering acting as a gateway. So that other ehternet port become Local LAN interface and connected to switch. Is it possible? I am thinking about adventure. What hurdles will i encounter.

I would assume you'd want an app on the phone that makes it act as a bridge, but I do not know of any such thing except the hotspot applications.

I am thinking following possible configurations.
Some sort windows server or linux server PC (or miniPC) with two network cards (one is ethernet and other is USB-C).
Setup dhcp to server the ethernet port.
Connect wireless switch to ethernet.
Confirure windows or linux server as a router so that all traffic from ethernet side will go to USB.
Feasible???

I read online about it somewhere, articles are scarce but at least one article said it may not work (not certain though) as wireless internet through smartphone uses different protocols or something.

It may be that the operation has to be done on a smart phone that has the OS broken into, in order to expose features that cell providers would rather have shut off.

what do you think it could be that cell phone providers shut off?
On a plusnote, i setup routing and remote access on my windows 2012 server and it worked some of my devices at my home!!
router is between home local LAN and USB connected smartphone which provides access.
With this configuration, Out of 6-7 devices at home, 2 of my devices (pc and laptop) had internet access through windows 2012 server acting as router. But rest did not have. Although it is welcome news that it worked, it still seems flaky.

I also not sure why other devices were not able to get online.
I installed wireshark perhaps to investigate and find something.

Cell phone providers may prefer that your phone operate only as a metered hotspot rather than an open-use router or bridge, for starters. They want their money if you have a metered plan that starts to pay them after a certain amount of usage.
