Abstract
By introducing GPRS, the operators have faced a new challenge for system planning. GPRS networks need different types of new expertise compare to that necessary in classical cellular systems. The introduction of new coding schemes requires cell and frequency planning that allow a GPRS network to provide a specific average throughput in a cell. Also, new dimensioning problems will be raised due to the new packet data service that, until the deployment of GPRS, was not considered. In the core network side, the new components and interfaces, mostly based on IP will add a new challenge to the core network dimensioning issue. For UMTS deployment, operators will face new challenges that will be different from GPRS issues. This tutorial is going to address the above issues with a practical and theoretical approach. There is a huge demand to answer these questions, both from operators and vendors.

The outline of the course will be as follow:
- Introduction to GPRS, UMTS and system planning
- Frequency and coverage planning
- Capacity and growth dimensioning
- GPRS network optimization and key performance indicators
- Value added services and integration into the GSM networks
- GPRS evolution and challenges
- UTRAN dimensioning and design issues

Who should attend : Managers and engineers involve in design and optimization of GPRS and UMTS networks with general knowledge of GSM.


Short Biography of the Speaker(s):

Dr Jafarian
serves as the head of Network Solutions Group in WFI. WFI is a full turnkey-service provider company with years of experience in providing high quality design and deployment solutions for wireless, cable, and fiber telecommunication systems. These services include the initial planning stage through post-deployment including program management, radio frequency (RF) engineering, site acquisition, microwave relocation, fixed network (backhaul) engineering, construction, optimization and Network Operations Centers. WFI's organization has grown to more than 1700 professional employees, working throughout North and South America, Europe, Middle East, Africa and Asia.

The Network Solution Group’s main activities include design and performance analysis of 2.5G/3G mobile and broadband fixed wireless networks. This also includes technology assessment and market analysis for 3G mobile systems (cdma2000 and UMTS). In this capacity Dr Jafarian has leaded different projects with different operators mainly focusing on technical issues and performance analysis for upgrading their existing network to 2.5G/3G.

Prior to join WFI, Dr Jafarian was an assistant professor in the Centre for Telecommunications Research, King’s College London from 1998 to 1999. He was one of the coordinators of BRAIN (broadband radio access for IP based networks) project, which is the main European project working toward 4th generation mobile systems.

Dr Jafarian received the B.S. degree in electrical engineering from Tehran University, Iran, in 1989 and the M.S. and PhD degrees in electrical engineering (mobile telecommunications) from King’s College London, University of London in 1994 and 1998, respectively. Dr Jafarian is the author of more than 20 conference and journal papers in the field of mobile telecommunications.
