Measurement and processing techniques for the exposure assessment of electromagnetic fields of base stations using spread-spectrum modulation
Christof Olivier, Luc Martens · 2002
When executing frequency-selective measurements around GSM/UMTS base stations to check the compliance with exposure guidelines, the use of spread-spectrum techniques should be taken into account when interpreting the measurement results and when estimating the exposure in the worst-case situation. In this paper techniques for measuring GSM signals using frequency hopping and processing the obtained measurement results are discussed. The measurement of a WCDMA signal used in UMTS with a spectrum analyser is also studied by means of a simple simulation model.
