4G LTE Evolved Packet Core (EPC) - Concepts and call flows

--- **Overview:** The global rating for this course stands at 4.39, with all recent reviews being positive, highlighting its effectiveness, especially in explaining complex concepts like Wireshark logs and the basics of LTE networking. The majority of reviewers found the course good for beginners, particularly those not from a telecom background. However, some areas for improvement were consistently mentioned across the reviews. **Pros:** - **Clarity of Instruction:** The course was praised for its clear explanations, which allowed understanding of key concepts around 4G and LTE architecture. - **Wireshark Content:** Reviewers appreciated the in-depth coverage of Wireshark logs, a topic that is often lacking in similar courses. - **Beginner Friendly:** The course was deemed suitable for beginners, with content pitched at an accessible level. - **Real-World Application:** Practical insights and understanding of network elements were emphasized as strengths. - **Engagement:** The inclusion of sessions with logs and practical scenarios contributed positively to the learning experience. - **Versatility:** The course was beneficial not only for theoretical knowledge but also for those in managerial roles within the telco industry. - **Value for Variety of Learners:** The course was valued by both industry veterans and newcomers to the field. **Cons:** - **Technical Accuracy:** Some reviewers pointed out discrepancies between the voice and written content, particularly with regard to names and terms used (e.g., "LTE as Ali," "Ran as Band"). - **Depth of Content:** There were calls for a deeper dive into certain topics, such as handover scenarios, tunnel usage, trouble shooting, operational issues, monitoring tools, type service in mobile for enterprise, and open RAN setups. - **Practical Exercises:** The absence of practical tasks or assignments using Wireshark for capturing call flows was noted. - **Completeness of Topics:** Reviewers requested inclusion of topics like SX interface for control plane and user plane separation, CUPS (Customer Premises Equipment), and IMS core elements and their functioning. - **Visual Aids:** Some found the text on slides to be too small, making it difficult to read, and suggested that diagrams could be clearer. - **Consistency in Subtitles:** There were mentions of subtitle errors and a need for accurate transcriptions to match voiceover content. **General Feedback:** - Reviewers expressed gratitude for the knowledge gained and the overall learning experience. - A desire for more comprehensive coverage of specific topics was consistently expressed. - The course was considered stimulating for those from different domains looking to enter the LTE field, especially in setting up open RAN. **Recommendations for Improvement:** Based on the reviews, it is recommended that the course developers: - Ensure technical accuracy and consistency across voiceovers and written materials. - Expand on certain topics where there are gaps identified by learners. - Incorporate more practical exercises, especially with tools like Wireshark for real-world application. - Enhance the clarity of visual aids such as diagrams and text on slides. - Consider creating supplementary materials, such as lab work or handouts, to enrich the learning experience. **Conclusion:** Overall, the course has been received positively for its clear instruction and practical content related to LTE networking. However, there is room for improvement in terms of technical accuracy, depth of coverage, practical exercises, and visual clarity. Addressing these areas can further enhance the learning experience and elevate the quality of the course.
