LTE, an acronym for Long Term Evolution, commonly marketed as 4G LTE, is a standard for wireless communication of high-speed data 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. It is based on an evolved standard from the GSM/UMTS standards by the 3GPP (Third General Partnership Project) and is often considered by many as a natural progression from 3G technologies.
Many WiMAX networks have recognized the advantages that LTE has in capacity, superior integration to existing cellular networks like 3G and increased data rates, and have therefore chosen to evolve their 4G networks into LTE networks. Many Greenfield deployments have naturally elected to deploy LTE technologies as an undoubtedly higher proportion of development by vendors in newer devices and networks in the consumer environment.
