Workshop Objective

Wireless communication is becoming more and more important, especially when high speed wireless data services are introduced. Hong Kong government is going to issue 4 to 6 licenses for 3rd generation wireless services. Most of the 3rd generation wireless systems are designed based on CDMA air interface. CDMA systems are very different, both in principle and in operation. Therefore, it is very important for the engineers and technical staffs in cellular operators to update their knowledge on CDMA. This workshop aims to provide the necessary information and skills for technical staffs, sales and marketing staffs to develop and understand the principle of CDMA and 3G Wideband CDMA systems.

Workshop Structure

This is a two-day workshop covering CDMA principles and operations. The workshop is divided into two parts: Introduction sections and practical sections. Day one of the workshop is at introductory level suitable for sales and marketing executives, technical staffs, and end users of CDMA systems. Day two of the course is at a more practical level, discussing worldwide standards and systems based on CDMA principles. Special emphasis is put in the operational and engineering details of 3G CDMA systems. Some practical simulation and exercise will be given to the students in between lectures.

Unique Features

• Cover the basic communication theory and CDMA principles for beginners.
• Cover both 2G IS95 CDMA system and 3G IMT2000 Wideband CDMA systems.
• Cover both theoretical background and practical operational aspects of CDMA.
• Emphasize extensive hands-on experience on CDMA system engineering.

Who should Attend?

Technical staffs from Cellular Operators who want to have a comprehensive update on the background and basics of CDMA systems. Sales and Marketing executives who want to have a more in depth knowledge on the common jargons of CDMA systems. It is expected that candidates have a preliminary basic understanding of communication systems, signals and cellular communication.
