PCWorld: “So-called “2G” (second-generation) network technology is differentiated from 1G primarily as a move from
analog to digital. Among the common 2G networks are CDMA, GSM, and TDMA. But 2G is slow for data
services; most wireless Web access moves at snail-like speeds of 10 to 19 kilobits per second. Proponents of
3G networks promise speeds from 384 kbps to 2 megabits per second. At 3G speeds, mobile phones or
handheld devices could handle high-speed multimedia and become all-in-one communication, entertainment,
and information devices.”
