Evaluation of the output power control of multi communication system mobile phones

In general, the results suggest communication technology is a strong predictor of exposure in mobile phone epidemiological studies. Different technologies can have a strong impact on the actual exposure, such as a factor >100 between GSM and UMTS. The same methodology can be applied to determine the relative daily exposure of specific tissues for specific mobile phones in specific networks when combined with tissue-specific exposure at maximum output level, when the results are normalized accordingly. The influence of the hand was mainly present for the UMTS communication system, since in GSM the average output power in dominated by peak power excursion during handovers.
