Minimum (•), maximum (•) and average (•) for each wireless technology. For comparison, ICNIRP reference levels for the public at 900 and 1800 MHz are also plotted.

All Mobile is the result of averaging over all mobile technologies. Only narrowband measurements (from 16 countries) could be used. The weighted averages for all available measurement years for each country were then averaged over the number of countries with measurements for each mobile technology. The figure in brackets on the horizontal axis label is the number of countries for which measurements were available for each technology.
