ABSTRACT
The Long-Term Evolution (LTE) is the newest cellular communications standard globally deployed. Regardless of previous generations, with the coexistence of different technologies for mobile access, all operators are globally converging to LTE for next-generation mobile communications. With a fully redesigned PHYsical layer, built upon Orthogonal Frequency Division Multiple Access (OFDMA), LTE networks provide orders of magnitude higher rates and lower traffic latencies, combined into a strong resiliency to multipath fading and overall improved efficiency in terms of bits per second per unit of bandwidth. This highly improved Radio Access Network (RAN) is architected over the Enhanced Packet Core (EPC) network to provide connectivity to all types of mobile devices [1].
