Course Overview
4G LTE remains the dominant mobile broadband technology in deployment globally, providing the core connectivity infrastructure for mobile data services across most markets and serving as the baseline network on which 5G Non-Standalone architecture is layered. For telecommunications engineers, network planning professionals and telecom regulatory officials, a thorough technical understanding of LTE architecture, radio interface, core network functions, protocol stack, mobility management and performance optimization is an essential professional competence that underpins work across network design, deployment, operations and regulation.
This Zoe Talent Solutions 4G LTE Training and Certification Course covers the complete LTE technical curriculum: mobile network evolution to LTE, LTE system architecture and network elements, the LTE radio interface including OFDMA, SC-FDMA and MIMO, physical channels and signals, LTE protocol stack, radio resource management, the Evolved Packet Core including MME, SGW, PGW and HSS, LTE procedures including attach, detach, handover and bearer management, QoS architecture, LTE Advanced features including carrier aggregation and enhanced MIMO, LTE network planning and dimensioning, drive testing and network performance optimization, and LTE security architecture. Participants gain both conceptual depth and practical applied knowledge across the full LTE technical scope.
Why This Course Is Required?
LTE is deployed in over 180 countries and serves the majority of the world’s mobile broadband subscribers, and LTE infrastructure will remain in service and require engineering management for the duration of the 5G transition period and beyond in most markets.[1] Engineers working on 5G Non-Standalone deployments, which use the LTE radio and core as an anchor, require comprehensive LTE competence as a prerequisite for effective 5G network work. Regulatory authorities overseeing spectrum allocation, quality of service compliance and mobile broadband coverage obligations must also maintain LTE technical literacy to discharge their oversight responsibilities effectively.
The ITU’s radiocommunication sector standards underpin LTE deployment globally, and 3GPP Release 8 through Release 15 specifications define the technical baseline that engineers, planners and regulators must understand to participate competently in network design, procurement evaluation, spectrum policy and performance management decisions.[2]
LTE is the foundation of mobile broadband globally and the anchor for 5G NSA deployments. Register for the 4G LTE Training and Certification course and ensure your team has the technical depth the technology demands.
Course Objectives
Attendees will learn about the following areas:
- Understanding the evolution from 2G/3G to 4G LTE and the architectural changes that enable LTE performance
- Analyzing the LTE system architecture: eNodeB, X2 interface, S1 interface and Evolved Packet Core components
- Understanding the LTE radio interface: OFDMA downlink, SC-FDMA uplink, subframe structure and physical resource blocks
- Applying MIMO antenna technology: spatial multiplexing, transmit diversity and beamforming modes
- Tracing the LTE protocol stack: PDCP, RLC, MAC and PHY layer functions and interactions
- Understanding EPC functions: MME signaling, SGW/PGW user plane, HSS and PCRF roles
- Analyzing LTE procedures: UE attach, authentication, bearer establishment, handover and idle mode mobility
- Configuring and evaluating LTE QoS: QCI classes, GBR and non-GBR bearers and policy enforcement

- Conducting LTE performance analysis and optimization: KPI frameworks, drive test data interpretation and interference management
Training Methodology
Zoe Talent Solutions follows the Do-Review-Learn-Apply model, developing LTE technical competence through lab exercises, protocol trace analysis, network planning worksheets and performance data interpretation sessions rather than specification-reading alone. Each module follows a consistent structure: a concise technical framing session that introduces the architecture or procedure, followed immediately by a hands-on exercise in which participants work through the technical material using real data, call flow diagrams or planning tools.
Protocol stack exercises require participants to trace actual LTE call flows — attach, bearer establishment, handover — step by step, identifying which protocol layer handles each function and what goes wrong when it fails. Drive test KPI interpretation sessions use real network data to develop the diagnostic skill of moving from a KPI anomaly to a root cause. Link budget and dimensioning exercises apply the mathematical tools to realistic planning scenarios, so participants leave with the ability to do the calculations rather than just understand them in principle.
The course is structured so that radio and core network topics alternate throughout the program, reinforcing the system-level view that the end-to-end performance of an LTE network requires. Each technical module is grounded through worked examples that connect 3GPP specification content to real network design and operations decisions that participants will face in their roles. The course agenda may be adjusted according to time availability and audience requirements to ensure complete coverage of all critical modules.
