From the 4G/LTE to the 5G-NR Air Interface 11.-13.11.2025
Training Focus
This training course is aimed at those people working within the wireless communication business or broadcast business. Participants will get an overview on the 4G/LTE and 5G-NR physical layer. First of all wireless communication basics like OFDMA, DFTs-OFDMA, Forward Error Correction and MIMO will be discussed followed by an in-depth overview of 4G and 5G technology and standards. The training is presented in cooperation with Rohde & Schwarz.
Course Objectives
After completing this course, delegates will understand the technology behind 4G and 5G. Focus is on the physical layer not on the protocol level. Several practical demonstrations will solidify the theoretical knowledge.
Intended for
This course is intended for those who have a basic knowledge in information technology, who may be employed in network operators or regulators.
