Abstract

The electromagnetic environment in a hospital is
characterized in order to evaluate the conditions for failsafe operation of critical electronic equipment. Field strengths within the University Hospital Z¨urich were measured at more than 60 different locations in the frequency range from 9 kHz up to 10 GHz. To account for variations in both, time and location, ’stationary short term’ and ’stationary long term’ measurements over 24 h were carried out. The measurement uncertainty of the
measurement equipment, calibration and measurement procedure is assessed. Measurement results are evaluated with respect to given immunity levels (EMC) and in-band interferences (EMI). The ISM band features a noise power density of -32 dBm/MHz while for Ultra Wide Band (UWB) there are different sub-bands with a maximum noise power density of less than -81 dBm/MHz. This suggests that communication in the UWB band requires significantly lower power levels than communication in the ISM band for equal dynamic ranges of the radio links.
