3G Network Optimization and Link Planning

Course Details... 
Introduction
 

At the end of this four days course the students will understand the essentials required and involved in planning of microwave based access network for GSM and 3G. They will develop understanding of migration of transmission network towards all-IP environment.

 

This course is designed to teach students the essence of microwave path planning. Once completed they will be able to design and maintain cost effective solutions. The students will also be learn how to design paths that will not suffer from interference, or disturb other radio systems in the vicinity.

Course Overview

Networks are migrating quickly from GSM towards 3G and beyond. Basic drivers for such migration is the rising needs of data and cost effective planning and expansions of backhaul links. Using this course students are able to understand the needs of new traffic types and wisely adjust transmission network evolution to handle both existing and new traffic types.

Classroom discussion of all the above topics will be complemented by interactive student exercises. The course concludes with a guide to several ITU-T/ITU-R references, students can access for additional information.

With the emerging carrier Ethernet standards and the migration of mobile telephony technologies towards IP technologies, the microwave radio systems have an increased focus on the effective transport of packet based traffic and major radio vendors have introduced a new type of radio, commonly referred to as IP radio supporting high speed packet transport over microwave links.

Applications:

 

 

  • Banking Sector, Clinic, Hospital

  • Factory area, Industry

  • Tourism Information Center

  • Mega events way finding assistance

Key Benefits

3G transmission planning requires understanding of both TDM and packet radio planning. This course helps in developing knowledge of

 

  • To understand how Microwave links are planned for 3G Access and Core Networks using microwave TDM and packet radios at different frequencies under different weather conditions using adaptive modulation ( only with packet radios)

  • To understand what components make up a total system and the significance of Layer 2 switching in 3G Transmissions access and core links.\
