* LTE is the most suited mobile technology as it provides higher data rates required for the future and is an advancement improvement over widely used the established GSM/EDGE/HSPAsystems* A number of corporate giants are looking towards LTE is promoted by major corporates as the technology enabling future communication* The following factors advantages are expected to be obtained with the realization of LTE

LTE (Long Term Evolution), is the latest standard in the mobile network technology that came into existence because of the growing needs of faster data rates. It is a 3rd Generation Partnership Project (3GPP), which realized this technology. LTE is an advancement to previously realized technologies such as GSM/EDGE and UMTS/HSxPA etc.Although LTE is often marketed as 4G, first-release LTE is actually a 3.9G technology since it does not fully comply with the IMT Advanced 4G requirements.  LTE-Advanced has been granted 4G compliance given the significant improvement they provide over 3G technologies [http://www.itu.int/net/pressoffice/press_releases/2010/48.aspx][[Image:lte-evolve.jpg|centre|500px|thumb|[http://www.4gamericas.org/index.cfm?fuseaction=page&sectionid=249 '''LTE Evolution''' ]]]

Update - LTE-Advanced has been granted 4G compliance given the significant improvement they provide over 3G technologies [http://www.itu.int/net/pressoffice/press_releases/2010/48.aspx][[Image:299.jpg|centre|300px|thumb|[http://www.unwiredview.com/2009/02/18/verizon-att-lte-details LTE technology ]]]Voice traffic will be supported mainly as Voice over IP (VoIP) enabling better integration with other multimedia services.LTE is being designed to be a high data rate and low latency system. LTE is also aimed at minimizing cost and power consumption while ensuring backward-compatibility and a cost effective migration from UMTS systems.

==MIMO(Multiple Input Multiple Output)== Multiple input multiple output (MIMO) technologies introduced Major players in LTE such as spatial multiplexing, transmit diversity, and beamforming are key components the ETSI list for providing higher peak rate at a better system efficiency, which are essential for supporting future broadband data service over wireless links.In Long Term Evolution (LTE), MIMO technologies have been widely used to improve downlink peak rate, cell coverage, as well as average cell throughput. To achieve this diverse set of objectives, LTE adopted various MIMO technologies including transmit diversity, single user (SU)-MIMO, multiuser (MU)-MIMO, closed-loop rank-1 precoding, and dedicated beamforming.

In one method, at least one data symbol stream is received for transmission from a plurality of antennas. Each data symbol stream is scaled with a respective weight corresponding to the amount of transmit power allocated to that stream. The scaled data symbol stream(s) are multiplied with a transmit basis matrix to provide a plurality of transmit symbol streams for the plurality of antennas. The transmit basis matrix (e.g., a Walsh-Hadamard matrix or a DFT matrix) is defined such that each data symbol stream is transmitted from all antennas and each transmit symbol stream is transmitted at (or near) the full power for the associated antenna.

For each transmitting antenna in an OFDM transmitter, pilot symbols are encoded so as to be unique to the transmitting antenna. The encoded pilot symbols are then inserted into an OFDM frame to form a diamond lattice, the diamond lattices for the different transmitting antennae using the same frequencies but being offset from each other by a single symbol in the time domain. At the OFDM receiver, a channel response is estimated for a symbol central to each diamond of the diamond lattice using a two-dimensional interpolation. The estimated channel responses are smoothed in the frequency domain. The channel responses of remaining symbols are then estimated by interpolation in the frequency domain.
