Course Objectives

Participants attending this course will be given the framework for 3G CN planning, dimensioning, and performance optimisation. During the course , we will discuss network design and planning, traffic analysis, and generic KPIs and counters. Example calculations will be done in reference to different CN nodes (in terms of different solutions) and QoS requirements, capacity and licensing dimensioning.

Prerequisites

Participants must have basic knowledge of Core Network. Practical experience is recommended.
