Course Details
If you are involved in the troubleshooting of 5G networks, you will appreciate that having a good understanding of the protocols is critical. This course, therefore, sets out to provide a detailed explanation of the key 5G protocols found in the NG-RAN and 5G Core. Specifically focusing on 5G NAS, RRC, NGAP, Service Based Interfaces, and PFCP. Furthermore, to enhance the explanations, the course incorporates examples through the use of Mpirical’s NetX network procedures.
