The course is designed for engineers and technical professionals requiring an intermediate level of understanding in the WCDMA system and its air interface. It also serves as a prerequisite for the WCDMA Radio Network Design course. System integrators seeking to have an in depth knowledge of UMTS system and radio planning will also find the course beneficial.
 

3 days (21 hours)
