SeaGlass Anomaly Near SeaTac Airport

Caption

The researchers captured 2000 broadcasts (blue dots) from a cell tower near Sea-Tac airport, which consistently had the same properties. The red dot represents one highly unusual signal - with properties that would be unexpected anywhere in the city - that would be consistent with an IMSI-catcher "pretending" to be that cell tower.
