Floating cellular data (FCD) leverages the constant pinging between mobile handsets and cellular base stations to map real-time movement. By analyzing handovers, signal strengths, and location updates from thousands of devices, network operators can determine traffic speeds and congestion without deploying physical road sensors. This anonymized telemetry is often sold to transit authorities and mapping services.
