    Notes: All speeds are theoretical maximums and will vary by a number of factors, including the use of external antennas, distance from the tower and the ground speed (e.g. communications on a train may be poorer than when standing still). Usually the bandwidth is shared between several terminals.

    3G technology provides an information transfer rate of at least 144 kbit/s. Later 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet ...

    [58] [59] By 2009, T-Mobile had expanded its 3G network to cover over 200 markets. [60] The company further enhanced its network capabilities by upgrading to HSPA+ in 2010. [61] In 2015, to optimize network bandwidth for the deployment of 4G LTE services, T-Mobile initiated a process of migrating 3G services to its PCS band.

    The requirements were set forth by the ITU-R organisation in the IMT Advanced specification; but, because of market pressure and the significant advances that WiMAX, Evolved High Speed Packet Access, and LTE bring to the original 3G technologies, ITU-R later decided that LTE and the aforementioned technologies can be called 4G technologies.

    Both EDGE and 1xRTT are 3G standards, as defined by the ITU, but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies. True 3G systems such as EV-DO , W-CDMA (including HSPA and HSPA+ ) provide combined circuit switched and packet switched data and voice services from the ...

    Higher speeds became available in 2001 and 2006 as part of the third (3G) and fourth (4G) generations. In 2011, 90% of the world's population lived in areas with 2G coverage, while 45% lived in areas with 2G and 3G coverage. [1] Mobile broadband uses the spectrum of 225 MHz to 3700 MHz. [2]
