5G: System Survey, Air interface and procedures


What 5G is? What will help to cope, what kind of problem will solve, what prospective will open? Will it be universal cure for all diseases? This course will give you an overview of the new radio technology in the RAN (also referred to as New Radio), the architecture EPC and Next Generation Core Network (also referred to as 5G CN). After the program participation you‘ll be able to answer questions above and have your own opinion regarding fundamental changes in 5G system development, evolution of system architecture.
