Internet access is available when the iPhone is connected to a local area Wi-Fi or a wide area GSM or EDGE network, both second-generation (2G) wireless data standards. Networks accessible from iPhone models include 1xRTT (represented by a 1× on the status bar) and GPRS (shown as GPRS on the status bar), EDGE (shown as a capital E on the status bar), UMTS and EV-DO (shown as 3G), a faster version of UMTS and 4G (shown as a 4G symbol on the status bar), and LTE (shown as LTE on the status bar).[84] The iPhone 3G introduced support for third-generation UMTS and HSDPA 3.6,[85] the iPhone 4S introduced support for HSUPA networks (14.4 Mbit/s), and support for HSDPA 7.2 was introduced in the iPhone 3GS.[86] and the iPhone 5 introduced support for 4G LTE. 5G Evolution is now supported on AT&T in areas where implemented and stylized as a larger 5G and reduced size capital E.[87] 5GE uses the 4x4 MIMO doubling the number of antennas, 256-QAM, and three-way carrier aggregation.
