UMTS RF Planning and Optimization
Course Duration
|
5-day instructor-led training with case studies
|
Course Objectives
|
The goal of “UMTS RF Planning and Optimization” is to present details and up-to-date information on the UMTS standard. The participants will become familiar with the features of the UMTS standard and why and how it evolved. The participants will learn about practical performance and deployment issues specific to the UMTS.
|
Course Overview
|
As UMTS-FDD proliferates worldwide, there’s growing demand for a good, strong course on the design and optimization of UMTS networks. This course is created to respond to that need.
In this course, students will build on their existing knowledge of the UMTS network architecture and operation by learning how to design and optimize a radio network based on the FDD mode of UMTS. They will learn both the user and network equipment protocols. They will cover in detail the connection of the FDD RAN to the 3G core and IP networks. They will also study in depth the dimensioning and optimization of both the radio and core network parameters. All in all, the course will help to design UMTS-FDD networks that provide optimum performance for broadband wireless services while also being cost effective.
