Long Term Evolution

The Long Term Evolution (LTE) is a net of broad band mvelque already is in test in the United kingdom and planning and implementation of testesnos United States and in the Sweden, that will have to be the next evolution to the redesmveis, according to 3GPP. The infrastructure of the nets will have to be improved how much eficincia in factors as speeds of access, latency and eficinciaespectral. The LTE has great prominence for making possible a capacity well superior denavegao of the existing nets 3G. The LTE promises: – download of 326,4 Mbits/s – tax of upload of 86,4 Mbits/s – gone time of and comes back (RTT) of less of 10ms – ray of the cells being able to reach up to 100 km. The main used standards today for the nets 3G (HSPA eUMTS) obtain approximately to reach taxes of 14 speeds of Mbps (Megabits for second), already tests with the LTE had pointed peaks of navigation with until 120Mbps.

Suffering a popularizao, the LTE will be able to make possible umnovo market of services and applications of multimedia content transmitted video HD aovivo saw LTE to a decoder IPTV in the home so that it is seen by the family eamigos; * Follow me Video stations base (Nodes-B) have 4 antennas at least. ‘ ‘ The LTE is based basically on protocol TCP/IP epossui E-UTRAN (Evolved UMTS Terrestrial Radio Access Network), analogous existing aoUTRAN in current nets UMTS.

The great difference is its interfacefsica with air, where the use of model OFDMA (OrthogonalFrequency-Division Multiple Access) for the direction of downlink was specified, being able serusadas up to 1200 carriers, and use of SC-FDMA (Single Carrier Frequency DivisionMultiple Access) for the direction of uplink.
