During the HackerSpaceFestival 2008, we installed a room with a TES92 ElectroSmog FieldMeter (50MHz – 3.5GHz) to be used to measure the Magnetic Field from different cellphones during a call. The people were asked to make a call with their cellphone at less than 5 cms from the field meter. The TES 92 had been verified using a spectrum analyzer and modulation generator at 1v/m. The EU regulation usually make the measurement using W/kg.
Please find below the results from the different cellphones :
