After a brief overview of mobile system UMTS, we will talk about enhancements that have been proposed and implemented to this system (including technologies such as HSPA or MBMS). 3GPP is currently in the process of defining the long-term evolution (LTE) for 3G, in order to maintain the future competitiveness of 3G technology. Features of LTE will be outlined and a comparison of technologies LTE and WiMAX (Mobile WiMAX) will be provided.
