5G is the next-generation of mobile networks beyond the 4G LTE mobile networks existing today. The vision of 5G is becoming clearer and most experts say 5G will feature network speeds that are blazingly fast at 20 Gbps or higher and have low latency at mere milliseconds. The entire 5G approach takes advantage of containers, virtualization, SDN and NFV.

Skills Gained

Students will cover the design motivation and underlying technology of 5G service-based architecture as well as new vocabulary terms. We will cover enough about 5G radio to understand the differences between 4G and 5G, and finally, take a look at the 5G core in action. Sample message flows of typical 5G processes are covered message by message. The goal is to clearly see how 5G accomplishes its goals by observing how it actually works.

Who Can Benefit

Anyone who needs a high-level overview of complete 5G rollout, Management, Planners and Project Managers.

Concise and good to follow along. Although it is a lot to take in under a short period of time.

Thank you for training on AWS development. Course was good and encouraging but labs need to be improved and provide more information and ask students to more work than provide solutions.

Very clean, great cafeteria and well sorted, very kind staff. The bathrooms have to be expanded as they might get crowded sometimes

It would be better if the classroom had two power point screens so the instructor could have two screens shown to the class at the same time to reduce confusion switching back and forth

This course gave me a clearer understanding of the AWS cloud architecture.
