Abstract: Long Term Evolution (LTE) is the project name of a new high performance air interface for cellular mobile communication systems.It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. Where the current generation of mobile telecommunication networks are collectively known as 3G, LTE is marketed as 4G. LTE is a standard for wireless data communications technology and an evolution of the GSM/UMTS standards .
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 in the U.S., which is partly owned by Vodafone, has already said that it will support LTE as its 4G technology of choice, abandoning its current CDMA based network.
