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.
