What is LTE (telecommunication)
LTE Stands for / full form of / abbreviation of LTE - Long Term Evolution,
Long-Term Evolution (LTE) is a standard for high-speed wireless communication for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements. The standard is developed by the3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. Y LTE is the upgrade same for carriers with both GSM/UMTS networks andCDMA2000 networks. The different LTE frequencies and bands used in different countries will mean that only multi-band phones will be able to use LTE in all countries where it is supported.
LTE is commonly marketed as 4G LTE, but it does 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 requirements were originally set forth by the ITU-R organization in the IMT Advanced specification. However, due to marketing pressures and the significant advancements that WiMAX, Evolved High Speed Packet Access and LTE bring to the original 3G technologies, ITU later decided that LTE together with the aforementioned technologies can be called 4G technologies. The LTE Advanced standard formally satisfies the ITU-R requirements to be considered IMT-Advanced.To differentiate LTE Advanced and WiMAX-Advanced from current 4G technologies, ITU has defined them as "True 4G".
The LTE standard supports only packet switching with its all-IP network. Voice calls in GSM, UMTS and CDMA2000 are circuit switched, so with the adoption of LTE, carriers will have to re-engineer their voice call network.Three different approaches sprang up:
Voice over LTE (VoLTE)
Circuit-switched fallback (CSFB)
Simultaneous voice and LTE (SVLTE)

What is "LTE"?
LTE, short for Long Term Evolution, is considered by many to be the obvious successor to the current generation of UMTS 3G technology, which is based upon WCDMA, HSDPA, HSUPA, and HSPA. LTE is not a replacement for UMTS in the way that UMTS was a replacement for GSM, but rather an update to the UMTS technology that will enable it to provide significantly faster data rates for both uploading and downloading. Verizon Wireless was the first U.S. carrier to widely deploy LTE, though MetroPCS and AT&T have also done so, and Sprint and T-Mobile USA both have plans for LTE. In fact, Sprint is phasing out its WiMAX network in favor of LTE. Verizon Wireless and AT&T currently have incompatible LTE networks, even though they both make use of 700MHz spectrum. AT&T and Verizon Wireless LTE customers often see download speeds that exceed 15Mbps, and upload speeds in the 10Mbps range.
