5G mMIMO RAN Design Principles
Course Contents
This 5G training course explains in detail the MIMO radio channel modeling as well as capacity and coverage impairments. The configuration of CSI-RS logical ports is discussed vs. channel estimation, SMUX and beamforming. Coverage Analysis and Throughput performance are evaluated and good planning hints are discussed and explained based on the requested achievable targets.
