The trainer is a Chartered Engineer professional
specialising in mobile communication technologies. He has conducted
numerous consultancy work in Europe and the Middle East. Companies
for which he had conducted consultancy and training include Orange,
Vodafone, Q-Telecom, Forthnet, TeliaSonera, IPwireless and ARCchart.
Topics include GPRS and WCDMA Radio Network Planning and Optimisation,
Wireless LAN and Broadband Wireless Access technologies like Flash-OFDM,
IPWireless TDD, WiMAX and WiBRO. He has considerable experience
on WiMAX Network Design and deployment and currently he is heavily
involved in WiMAX consultancy and training in many parts of the
world, some of which are based in Europe and Asia.
He graduated from the University of Bristol with a degree in
Electrical & Electronic Engineering and he holds an MSc in Mobile
Communication Systems & DSP from the same university. After his
studies, he has been involved as a research engineer with future
wireless communication technologies (3.5G, 4G, MIMO etc...) at
the Orange Research & Innovation department in Bristol UK. After
gaining very valuable skills and knowledge on different air interface
technologies, he has been appointed a 3G Senior Network Planning
Engineer, responsible for designing, planning and optimising the
Orange UK 3G network. For the past 3 years, he is working as a
freelance wireless communications consultant with projects mainly
from mobile network operators and broadband providers. He is also
currently pursuing an MBA from the University of Edinburgh.
Course Objectives
By the end of the course delegates will
be able to:
• Explain what WiMAX is
• Describe the WiMAX principle of operation
• Describe the WiMAX architecture
• Be able to compare several BWA technologies over WiMAX for BWA
service deployment.
Course Overview
This course will provide the student with
broad knowledge on current WiMAX and 802.16 standards, trends, issues
and technologies. It compares BWA technologies to WiMAX and studies
all issues regarding WiMAX as a Broadband Wireless Access Technology.
Technoeconomics of WiMAX as a BWA solution is also included.
Key Benefits
Delegates will be trained on state-of-the–art knowledge regarding
WiMAX BWA.
Pre-Requisites for Participants
Good knowledge of radio and network basics.
Knowledge of IP protocol is required but not essential.
Who Should Attend?

and trade-offs of
WiMAX as a BWA technology
Development Engineers requiring a good end-to-end introduction
to the operation of WiMAX network
Radio Network Engineers
Anyone who needs to know about WiMAX, how it works and how it
is deployed.
