* 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.

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:299lte-evolve.jpg|centre|300px500px|thumb|[http://www.unwiredview4gamericas.comorg/2009/02/18/verizon-att-lte-details index.cfm?fuseaction=page&sectionid=249 '''LTE technology Evolution''' ]]] 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.

The total transmit power is allocated to the subbands based on a particular power allocation scheme (e.g.product, full channel inversion, selective channel inversion, water-filling, or uniform).
