2014 NOV 14 (NewsRx) -- By a News Reporter-Staff News Editor at Health & Medicine Week -- Current study results on Environmental Health have been published. According to news reporting from Bern, Switzerland, by NewsRx journalists, research stated, "Models for exposure assessment of high frequency electromagnetic fields from mobile phone base stations need the technical data of the base stations as input. One of these parameters, the Equivalent Radiated Power (ERP), is a time-varying quantity, depending on communication traffic."

The news correspondents obtained a quote from the research, "In order to determine temporal averages of the exposure, corresponding averages of the ERP have to be available. These can be determined as duty factors, the ratios of the time-averaged power to the maximum output power according to the transmitter setting. We determine duty factors for UMTS from the data of 37 base stations in the Swisscom network. The UMTS base stations sample contains sites from different regions of Switzerland and also different site types (rural/suburban/urban/hotspot). Averaged over all regions and site types, a UMTS duty factor for the 24 h-average is obtained, i.e., the average output power corresponds to about a third of the maximum power."

According to the news reporters, the research concluded: "We also give duty factors for GSM based on simple approximations and a lower limit for LTE estimated from the base load on the signaling channels."
