UMTS Optimization and HSPA

Course Description

As traffic is growing in 3G networks, there is an increasing demand of optimizing the networks. Planning and optimization are continuous processes and therefore it is of great importance for most operators to gain and maintain these skills within the company. Let your staff learn from the experts that have already seen and solved the problems they are facing today.
