Course Objectives
RAN optimization is making a significant impact on the
mobile communications industry by providing an enhanced user
experience. This course seeks to identify effective
strategies and general procedures that enhance the
optimization process, suggest appropriate changes to power
control parameters in a range of optimization techniques,
suggest appropriate changes to cell re-selection parameters,
perform verification of typical GSM cell link budget and
cell balancing calculations. Participant will have
comprehensive understanding of optimization, spectrum
utilization, spectrum planning and capacity and quality of
service management for RF systems.
This
course will also enable participants to:
Develop an understanding of what RAN Optimization
is and what it can do, including the motivation for its
development and its present capabilities.
Help the engineering team in planning and
performance management for radio access network. Assist
them to have a better understanding of the parameters
involved and KPI metrics.
Develop an appreciation of how RAN Optimization
Principles and related technologies can be used to deliver
value to customers, including an exploration of what is
meant by "quality of service" and a discussion of the
network technology, management systems and business
processes required to deliver customer value.
Course Overview
GSM networks are being pushed to the limit in terms of
capacity. High performance at high traffic levels comes from
effective network optimization. An implementation of good
optimization process needs a wide knowledge including a
thorough understanding of radio and radio propagation, GSM
air interface operation and failure scenarios. This course
provides an interactive in-depth knowledge of RAN
optimization strategies and principles.
Key Benefits
The participants will gain a detailed end-to-end
knowledge of the RAN Optimization principles, its benefits
and potential pitfalls.
Pre-Requisites for Participants
A basic understanding of GSM technology will be
required.
Who Should Attend?
Technicians, engineers, radio network planners and
optimization engineers, managers, or other personnel
responsible for Cellular / Mobile Systems.
