How to legally launch a free Wi-Fi network in the city?

Question

Computer networks

I want to launch a free Wi-Fi network in city cars, in other words, put 3G / 4G routers in cars.
A license for Wi-Fi below 10 meters above the ground does not seem to be required now. As far as I understand, only two things should be provided by law:
1. User identification (decided).
2. Support for blocking sites from the registry of prohibited.
The question concerns the second part:
1. Since the Internet will be provided by a mobile operator that is already blocking traffic, will Roskomnadzor understand this or will it still need to show him your filtering system?
2. Is it possible to run such a filtering system on a 3G/4G modem?

Answer 1

1. Telematic Services License
   And no one in the supervisory authorities cares that you are not the final operator
   Oh, and even get ready to become a personal data operator

Answer 2

The case is very exciting, I know firsthand, because. I am also dealing with this issue.
We can combine our knowledge if there is still time and desire to do it.
