3G is a group of wireless communication technologies used by cellphones.

Health impacts

A 2 year study by the National Toxicology Program found "that high exposure to RFR (900 MHz) used by cell phones was associated with" evidence of malignant tumours in the hearts, brains and adrenal glands of male rats. "It was unclear if tumors observed in the studies were associated with exposure to RFR in female rats (900 MHz) and male and female mice (1900MHz)." NTP scientists also "found that RFR exposure was associated with an increase in DNA damage."[1]

Decline and decommissions

Since the increasing adoption of 4G, 3G use has been in decline. Several operators around the world have already or are in the process of shutting down their 3G networks. In several places, 3G is being shut down while its older predecessor 2G is being kept in operation - Vodafone Europe is doing this, citing that 2G is a useful low-power fall-back.[2]
