Description
The RF planning for 5G NR is quite challenging as compared to legacy networks due to the introduction of advanced new technologies: mmWave frequencies, flexible numerology and Massive MIMO (M-MIMO) etc. This course takes a deep dive into the technical insights necessary for the radio network planning both in the the mid-band and mm-wave spectrum. The 5G RF design and planning process is discussed both from the perspective of the system coverage and capacity objectives.
