Shot noise has been measured in three different environments: an urban street, a factory, and a train station, and the results are presented in this Letter. The measurement system was designed to operate at UMTS band and to provide both phase and envelope of the shot noise. It has been found that the train station is not a very noisy environment. In the factory shot‐noise events are less frequent than on the urban street; however, noise pulses appear more grouped in bursts. Noise pulses exhibit a larger amplitude and shorter duration in the factory than in the street measurements. In both cases, shot‐noise pulses have very high amplitude and duration compared to the limits for UMTS signals. © 2002 Wiley Periodicals, Inc.
