5G Network Architecture, Planning and Design
Course Overview
This course provides a comprehensive understanding of 5G network architecture, planning, and design, covering the technological advancements that define the next generation of mobile networks beyond 4G/IMT-Advanced standards.
Participants will explore key 5G technologies, including Massive MIMO and advanced transceivers with beamforming, improving spectral efficiency and network performance. The course will cover beam sweeping techniques, optimizing coverage and connectivity, along with carrier aggregation, allowing the combination of multiple frequency bands to enhance throughput.
The course will also delve into 5G’s flexible frame structure, covering numerology, subcarrier spacing (SCS), and physical channels, enabling diverse use cases with varying latency and bandwidth requirements. Multi-connectivity and aggregation concepts, such as LTE + NR Dual Connectivity, and use of Multiaccess Edge Computing (MEC) will be discussed to highlight the seamless transitions between legacy and next-generation networks.
A deep dive into distributed flexible architecture will include the role of Central Unit (CU) and Distributed Unit (DU) in 5G network deployments, ensuring efficient traffic management and low-latency services. Essential planning and design considerations to optimize network performance, such as MAPL calculation, CI/CIF propagation models, Physical Resource Block (PRB) allocation, and Physical Cell Identity (PCI) management, will also be covered.
Additionally, the course will address 5G security and authentication mechanisms, including Security Anchor Function (SEAF), Authentication Server Function (AUSF), Subscription Permanent Identifier (SUPI), and Subscription Concealed Identifier (SUCI), ensuring secure communication in next-generation networks.
Participants will gain insights into real-world 5G use cases, such as IoT, Smart Cities, Autonomous Driving, low-latency remote control, and Device-to-Device (D2D) communication, evaluating how 5G networks outperform 4G in speed, agility, and intelligence.
