4G LTE: Architecture, Protocols, Call Flows, KPIs, Optimization, Performance Analysis

Learning objectives

[]Explain the evolution of mobile networks, the role of standards bodies, and the end-to-end architecture of a 4G LTE network, including RAN, Transport, and Core components.
[]Analyze the LTE physical layer, including its frame structure, modulation, multiple access scheme (OFDMA), and the function of key downlink and uplink channels through practical simulations.
[]Map the LTE protocol stack data flow, detailing the functions of the RLC, MAC, and RRC layers, and connect radio procedures to core network functions and call flows.
[]Evaluate network performance using industry-standard KPIs for Accessibility, Mobility, and Retainability, and analyze real-world data from drive tests and network reports.
[]Execute optimization processes to solve coverage, capacity, and throughput challenges, applying methodologies for link budget calculation, root cause analysis, and radio resource management.
