LTE Radio Network Design Workshop

The LTE Radio Network Design Workshop training presents the complete workflow of the LTE radio network dimensioning to meet operator’s coverage and capacity requirements. Coverage and capacity calculations and their results are carried out and visualised with use the LTE RND software tool developed by ENKI.

The training explains the LTE design requirements and system characteristic particularly important from radio network design perspective, including channel bandwidth, physical layer bit rate, signalling overhead, maximum user throughput, MIMO, link adaptation, scheduling, UE categories and eNB hardware. Next, the design inputs, e.g. frequency, antenna radiation pattern, downtilt, cell load and UE power control parameters are explained together with their impact on the network coverage and capacity.

Step-by-step, each calculation is explained in details with an example exercise. The results of each exercise are illustrated by a dimensioning graph of the LTE RND tool. Each participant uses the LTE RND tool to design an LTE network with characteristic, coverage and capacity requirements of her/his interest. The course also explains the techniques of physical channels dimensioning and important design parameters dimensioning including PCI and tracking area dimensioning.
