LTE and SAE : The Protocol Architecture in Mobile Broadband

This paper is to describe the new wireless communication technology Long Term Evaluation. LTE became the most powerful technology in cellular system to achieve the high speed, spectral efficiency and reduce latency rate in uplink and downlink. The LTE architecture is known as (SAE) service architecture evolution. SAE is the combination of Evolved universal terrestrial radio access network and Evolved packet core. This paper explained the working principle and functionality of different entity in LTE architecture and also described the Protocol stacks between user equipment, ENodeB and Evolved packet Core. The protocols stacks are divided into control plane and user plane. The major function of these protocols is to manage the overall functionality of LTE architecture system.
