Abstract
In a general aspect, vapor cell sensors are used to perform over-the-air (OTA) testing of cellular base stations. In some implementations, a vapor cell sensor including a vapor having Rydberg states is tuned to a carrier frequency of RF radiation emitted from a cellular base station. A first set of optical signals is generated based on an interaction between the vapor and a synchronization signal transmitted from the cellular base station. The vapor cell sensor is tuned to a harmonic of the carrier frequency. A second set of optical signals is generated based on an interaction between the vapor and the RF radiation. The first and second sets of optical signals are converted to digital data. The digital data is processed to detect a condition of the cellular base station.
