Somebody’s watching me – Adventures in Cellular Location services
Summary
The article explains multiple location accuracy levels in cellular networks (Tracking Area, CGI, GNSS LPP, OTDOA), how networks determine device positions, and privacy implications, including a real-world misconfiguration that leaked CGI data. It emphasizes that this behavior is defined by 3GPP standards and provides practical insights into signals and tooling used to infer location, making it valuable for IT security and network engineering readers.
