For the transmissions, it can in such a way serutilizada technique TDD (Time Division Duplex) how much FDD (FrequencyDivision Duplex). ' ' (PASINATO, 2008) use datecnologia OFDMA (Orthogonal Frequency Division Multiple Access) in downlink (ERB for the cellular one) and SC-FDMA (Single Carrier Frequency Division MultipleAccess) in uplink (cellular for ERB); velocidadeno downlink of 100 Mbps and 50 Mbps in uplink, both with a width of band de20 MHz; operaesnos ways FDD (Frequency Division Duplex) and TDD (Time Division Duplex); use deantenas MIMO (Multiple-input multiple-output); handoffautomtico for other compatible standards.

Visamelhorar standards UMTS, using to advantage the available specter. the LTEpromete taxes of download of 326,4Mbits/s, taxes of upload of 86,4Mbits/s, gone time of and comes back less (RTT) of of 10ms and ray of the cells being able atingirat 100km. Comparative degree with the Wimax: Exactly with the promises to increase the potential of utilizaode videos, musics, downloads, in the systems wireless, the sector of deequipamentos sales for net so will not be affected in short term, they operadorasdevem therefore them to have a more defensive position waiting that the system ripens. In the world-wide congress of mobility (Mobile World Congress2008) of 2008, carried through in Barcelona, it was presented use tests dLTE for Ericsson. Recently Facebook sought to clarify these questions.

The linkings had been made with cellular and comequipamentos devices of proper Ericsson, reaching taxes of 160 data of megabits porsegundo. Also in the tests de200MB in less had obtained to carry through one download of an archive than 10 seconds and one streaming to the HD living creature (Tv Digital). Almda Ericsson, operators as detestes China Mobile and NEC had announced the accomplishment and negotiations of the one on the new technology. The expectation for the commercial launching of the nets estprevisto for 2010. Exactly that the characteristics between the sejamsemelhantes technologies, studies point with respect to the conviviality of Wimax and LTE in the future.
