LTE stands for Long Term Evolution which is a new radio platform technology that will permit carriers to give you higher wireless upload and download speeds currently between 5-12 mbps however expected to increase.
Verizon Wireless, AT&T & MetroPCS in the US and several worldwide LTE carriers started rolling out the new network in 2009. The world's first publicly available LTE service was opened in December of 2009 by TeliaSonera in the two Scandinavia.
LTE is part of the GSM evolutionary path beyond 3G technology, following EDGE, UMTS, HSPA (HSUPA and HSDPA combined) and HSPA Evolution (HSPA+). LTE is a set of improvements to the Universal Mobile Telecommunications System (UMTS) which was introduced in 3rd Generation Partnership Project (3GPP) Release 8. HSPA Evolution is a stepping-stone of speeds to LTE for numerous carriers that will be rolled out slowly.
Carriers started working on LTE in 2004 3GPP and initial deployment of LTE is targeted for 2010 and 2011. The aim of LTE is to provide a high performance radio access that offers good signal coverage in automobiles that are moving and that can coexist with HSPA and earlier networks. Network Carriers can scale bandwidth to migrate their networks and users from HSPA to LTE over time in areas that need it most.
4G LTE is known for high speeds in theory, but the promised speeds are hardly ever met. Here are some tips & tricks to increase 4G LTE speed from Techpp.com.
