  1. RF radiofrequency, ELF extremely low frequency, EF electric field, MF magnetic field; aIn Gipuzkoa 80 homes and 26 schools have been measured for the whole EMF-NIR range; bOnly in the middle; cThe start frequency for each span corresponds to 1.2 % of the span. The frequency bands are: 5–100 Hz; 12 Hz-1 kHz; 1.2-100 kHz; dAt 1.4 m from the wall; eFrequency bands: 87.5 - 108 MHz; 470–790 MHz; 791 – 821 MHz; 832 – 862 MHz; 880 – 915 MHz; 925 –960 MHz; 1710 – 1785 MHz; 1805 – 1880 MHz; 1880 – 1900 MHz; 1920 – 1980 MHz; 2110 – 2170 MHz; 2400–2485 MHz; 2500 – 2570 MHz; 2620 – 2690 MHz; 3400 – 3600 MHz; 5150 – 5875 MHz; 1,2 and 3; methodology described in more detail in the text; fAt 1.7, 1.1 and 1.5 m in the middle, and only at 1.5 m in the corners
