Thank you all, for the answers. Still one nagging question, though: NOt stated by T-Mobile on the 4G LTE Overview page is its use of the 1900 MHz frequency. As mentioned in the 4G Overview Additional Info, T-Mobile is switching some 1900 MHz frequency from EDGE to HSPA+.This will allow devices that work on 1900 MHz, such as AT&T devices, to use our 4G network..e: LTE Band # and Frequency. Don't let anyone else tell you otherwise, HSPA+ is an addition to the 3G standard to provide higher data rates than originally scheduled. What T-Mobile's doing is moving 3G/HSPA+ service off its 1700 MHz band and onto 1900MHz, where more phones support it globally.
The utility frequency, line frequency or mains frequency is the nominal frequency of the oscillations of alternating current in an electric power grid transmitted from a power station to the end-user. In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz. Current usage by country or region is given in the list of mains power around the world. During the development of commercial electric power systems in the late 19th and early 20th centuries
