Step-by-step recipe to find a 5G cell: tune to the band (FR1/FR2), capture 3.84 MS/s capture for a 256‑pt FFT when using 15 kHz spacing, correlate against the PSS (only three possible sequences) and look for PSS correlation peaks every 20 ms. After detection, recover PBCH and SSB beams (up to 64 beams in FR2) to get cell ID and attempt SIB1; real captures show clean correlation peaks and recoverable symbols but PBCH/SIB1 decoding is complex and implementation‑heavy.
