The new security feature makes it more difficult for police and malicious hackers to obtain a person's precise location data from a cell phone company.
Radio towers are all ready adjusted to the location where they are setup. The signal to you phone has already taken into account bounces, amount of buildings, material on the buildings, how it effects the amplitude, wavelength, signal strength and disruption. And the signal is adjusted to take all those things into account, relative good to send you 5g frequencies with minor issues. They have no issue triangulating phones, trust me.
Okay, according to this somewhat recent paper, chapter VI, C., static “obstructions” (e.g. buildings) can be put into a model and «precise position estimates» can be calculated «even in obstructed line-of-sight scenarios». Emphasis on “estimates”. But it’s only talking about one obstruction, not multiple in a complex arrangement. But, of course, the more BTSes receive you, the better the prediction.
It’s a whole science there are multiple techniques involved. Looking up stuff like Path Loss should be a start if you are intressted, you can also probably read the 5G protocol from Ericsson or Qualcomm, to find more details of their capabilities.
