Course Description:cloud understanding5G

Historically, there has been a major revision of mobile networks every ten years. The fifth generation of mobile networks is called 5G. 5G encompasses a major evolution of the over-the-air interface, and puts into place a new functional network architecture for delivering services over both fixed and wireless networks.

The 5G specifications are developed by the 3GPP. The course takes the learner through the 3GPP radio and network specifications that deliver the 5G requirements and use case scenarios, including ultra-reliable low-latency communications. The learner will also gain an understanding of how 5G is being implemented, and how 5G interworks with non-3GPP networks, such as Wi-Fi networks.

This course is designed for learners that need to have a broad technical understanding of 5G radio and core network functions. This course is 70% lecture and 30% class room exercises. Exercises are a combination of quizzes and analyzing 5G network messages in Wireshark.

Course Objectives:

  • Define key acronyms and terminology used in 5G specifications
  • Build a solid technical understanding of the New Radio (NR) and Network Functions (NF) defined in 5G.
  • Describe the impact of operating in different frequencies bands on the deployment of 5G networks.
  • Detail the key operational processes for establishing a “network slice” with the desired QoS to support different services.
  • Understand how 5G will interwork with non-3GPP networks, in particular Wi-Fi networks.
  • Gain technical expertise on 5G and why it is important to our network future, and how you can better manage that importance in your job function


The target audience for this course is anyone in engineering, testing, customer support, technical marketing and sales, system and solutions engineers. The course is ideal for anyone that requires an understanding of the fundamental operations of 5G and seeks to comprehend the challenges of 5G
that can be applied to their job function.

Ideal candidates are:

  • Operations and administrative people that provide wireless configuration and network support services.
  • Network architects and engineers that need to understand next generation wireless networks.
  • Network administrators and management that are providing element and network management tools to manage next generation networks.
  • Technical marketing and sales that must be able to correlate customer needs with emerging wireless network functions and capabilities.
  • Solutions and systems engineers that want more than just a basic understanding of the technologies and architectures underlying 5G.
  • Research and development individuals that need to expand their knowledge and studies of 5G technologies and wireless network topologies.
  • System and project planners that need to plan for future network deployments and growth.

Course Prerequisites:

This course is designed to appeal to anyone that needs to be knowledgeable on 5G networks and how they interwork with 4G and / or Wi-Fi networks. It will also appeal to learners that needs to understand how 5G plans to support the predicted exponential growth in wireless traffic, the emerging IoT market.

The ideal student will have some experience in 4G wireless technologies, networks and/or operations. Students with no prior knowledge of mobile wireless networks would benefit from taking the 4G 101 Foundation and 4G 201 Advanced courses prior to taking this class. However, no prior knowledge is required.

Many of the exercises use the Wireshark packet analyzer to explore 5G network messages. No prior knowledge of Wireshark is required, however students are expected to download and install the latest version of Wireshark before coming to class (https://www.wireshark.org/download.html).

Course Materials:

Learners will be provided with course material, exercises, and supporting reference material via the Online School of Network Sciences.
