Is the new 3G network, UMTS, more dangerous than GSM?
There are no indications that radio signals from the new mobile network will involve an increased health risk. On the contrary, there is much to suggest that radiation from UMTS equipment is lower than that emitting from GSM equipment. UMTS phones and antennas transmit with lower effect than GSM equipment. The UMTS frequencies are also somewhat higher than the GSM frequencies, which make them less capable of penetrating the human body. UMTS equipment does not transmit on constant pulses, as GSM does. Combined, this ensures that the WHO has introduced a less strict limit value in the frequency band for UMTS radio signals than for GSM radio signals.
