Abstract
In a general aspect, vapor cell sensors are used to perform OTA testing of cellular base stations. In some implementations, a system for performing OTA testing of a cellular base station includes a vapor cell sensor including a vapor having Rydberg states and a control system communicably coupled to the vapor cell sensor and configured to tune the vapor cell sensor to a carrier frequency of RF radiation emitted from the cellular base station; receive a first set of optical signals generated based on an interaction between the vapor and a synchronization signal; tune the vapor cell sensor to a harmonic of the carrier frequency; receive a second set of optical signals generated by the vapor cell based on an interaction between the vapor and the RF radiation; convert the first and second sets of optical signals to digital data; and process the digital data to detect a condition of the cellular base station.
