4G LTE
—Fourth Generation Long Term Evolution. LTE is a standard for wireless data
communicationstechnologyandanevolutionoftheGSM/UMTSstandards.ThegoalofLTEisto
increase the capacity and speed of wireless data networks using new DSP (digital signal
processing) techniques and modulations that were developed around the turn of the
millennium. Afurthergoal isthe redesign and simplification of the network architecture to an IP-
based system with significantly reduced transfer latency compared to the 3G architecture. The
LTEwireless interface is incompatible with 2G and 3G networks, so that it must be operated on a
separate wirelessspectrum
