This training is an excellent choice for engineers responsible for the radio access network planning. Contrary to previous generations, 5G for the first time utilizes very high frequencies reaching 60GHz also called mmWave bands. These high frequency bands offer a wide spectrum that is vital for the improvement of the network performance. However, this comes at a cost. Free space propagation loss increases significantly for the high frequency bands. As a consequence cell radius is much smaller compared to former technologies. This network densification has a significant impact on the radio planning. New propagation models and planning techniques are required. Also other aspects like energy efficiency have to be taken into consideration. This course presents the latest developments in cell planning focused on 5G system.

Target audience:

The course is intended for 5G system technical staff responsible for radio network planning, design and optimisation.
