Description: I am trying to create a map to see how people carrying a cellphone move inside of a given region (e.g. a building). Since not everybody has Bluetooth or Wi-Fi turned on, I was trying to rely on the 5G network or other passive signals that would allow me to triangulate the cellphone position (lat/lon) at any given instant (t). In this way I would be able to reconstruct the trajectory.
Question: Are you aware of any potential project/tutorial that would allow me to achieve this task? Maybe some open source library which may include also buying some antennas or whatsover?
PS: with regards to data privacy, I am not interested in personal data rather to the position of the device which could have an anonymous id.
