LTE Network Specialist Certification

Last updated on 

Here's a breakdown of the technical aspects covered in the LTE Network Specialist Certification:

  1. LTE Technology Overview: Candidates are expected to have a deep understanding of LTE technology, including its architecture, protocols, and key components. This involves knowledge of radio access network (RAN), evolved packet core (EPC), and the interfaces between them.
  2. Radio Access Network (RAN): In-depth knowledge of LTE radio access technologies, such as OFDMA (Orthogonal Frequency Division Multiple Access) and MIMO (Multiple Input, Multiple Output), is essential. This includes understanding how base stations (eNodeBs) communicate with user devices, spectrum utilization, and radio resource management.
  3. Evolved Packet Core (EPC): A solid grasp of the EPC architecture, including elements like Mobility Management Entity (MME), Serving Gateway (SGW), Packet Data Network Gateway (PGW), and interfaces like S1, S5, S8, etc., is crucial. Understanding the flow of user data and signaling within the EPC is also important.
  4. LTE Protocols: Detailed knowledge of LTE protocols such as RRC (Radio Resource Control), PDCP (Packet Data Convergence Protocol), RLC (Radio Link Control), MAC (Medium Access Control), and others. Understanding how these protocols interact and contribute to the overall functioning of the LTE network is necessary.
  5. LTE Network Planning and Optimization: Candidates should be proficient in network planning, deployment strategies, and optimization techniques. This includes aspects like coverage planning, capacity planning, interference mitigation, and quality of service (QoS) management.
  6. LTE Performance and Troubleshooting: Ability to analyze LTE network performance metrics, identify issues, and troubleshoot problems related to connectivity, throughput, handover failures, etc., is a critical skill set. Knowledge of tools used for performance monitoring and analysis is often included.
  7. Emerging LTE Technologies: Awareness of advancements and upcoming trends in LTE technology, such as LTE-Advanced, carrier aggregation, enhanced MIMO, IoT support, and 5G evolution, might also be part of the certification.
