Footnote:

For this base station the measurement of demodulated pilot signals of the spread-spectrum technologies (CDMA, UMTS or WCDMA) was not performed. Extrapolation was done assuming that only the pilot signal was present when in fact a mixture of pilot and traffic signals contributed to the measured value. This assumption leads to over-estimates of the actual RF EME levels, typically by a factor of 2 to 5.
