What are the current methods to identify fake base 4G stations?
a fake base station has reached a hight level. Does anyone have any document operating theory about the device, how this device working with 3G/4G networks? What are the current methods to identify fake base stations?

As i have already explained, DRT4311 scanner can help
Why TCXO Matters
Frequency Stability: Legitimate BTS towers typically use more expensive and precise OCXO (Oven-Controlled Crystal Oscillator) components for their internal clock. This ensures a very stable and accurate carrier frequency.
TCXO Limitations: Fake BTS towers, to cut costs, might use the less precise TCXO (Temperature Compensated Crystal Oscillator). This can lead to slight variations or drifts in the carrier frequency.
How it Helps
Potential Indicator: A DRT4311B, with its frequency measurement capabilities, could potentially detect subtle frequency drifts or instabilities that might suggest a TCXO-based oscillator, and thus a possible fake BTS.
