plus as anyone doing navigation with these open source phones knows, 3gpp location is embarrassingly low resolution without a supplemental source like WiFi SSID visibility, which has to be measured client-side. plus cell networks are asymmetric (SNR is higher from tower -> cell than from cell -> tower) so all else equal triangulation on the tower side should be even lower resolution.
