3G is a collection of technologies including EDGE, UMTS, HSDPA, and HSUPA that promise to bring high-speed data services to mobile work forces. Progress toward ubiquitous 3G coverage is being made, but competition from rival technologies such as WiMax continues to complicate the market. Many users have rushed to purchase 3G smartphones, and roaming between carriers continues to be a concern. Still, 3G holds enormous promise for users to always be on the cellular network without the security worries of using a wireless hotspot.
