This course is kept up to date in step with evolving standards for LTE and 5G, following the 3GPP quarterly meeting cycle. The contents listed in bullets below may therefore change slightly from one course event to the next. The chapters in the course relating directly to 5G will be expanded as the standard evolves (5G phase 1 will be completed in September-2018).


Basic technical knowledge about the LTE radio interface and, to a lesser degree, evolved packet core. Apis’ course ‘LTE/EPC System Overview’ provides necessary background information.

NOTE: The LTE Evolution training is not delivered with the FoldOut methodology.

‘Very good way of taking a course. Possibility to go back a double check topics’
