The LTE Advanced standard formally satisfies the ITU-R requirements for being considered IMT-Advanced. 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. LTE is also called 3.95G and has been marketed as 4G LTE and Advanced 4G but the original version did not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. In telecommunications, long-term evolution ( LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/ EDGE and UMTS/ HSPA standards.
