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
Wireless LAN technical workshop provides
the delegates with the most up-to-date information on the WLAN standardization
in IEEE and on the practical deployment and performance. The participants
will become familiar with the operation of all current and near-term
WLAN technologies based on the 802.11x standard. They will also
understand the capabilities of the WLAN technology, its planning
and optimization as well as aspects of integration within consumer
electronic devices.
Course Overview
WLAN technical workshop provides a state-of-the-art
insight in current Wireless LAN technologies based on the 802.11b,
g, a, n standards. It starts with the basic WiFi standard moving
on to higher speed standards like the 802.11g, a and finally to
the new 802.11n technology using MIMO. It addresses the full WLAN
operation, deployment, integration within consumer electronic devices
as well as topics of wireless security.
Key Benefits
What WLAN is and the market opportunities
What can be delivered using WLAN technology
How WLAN can be deployed
How WLAN can be integrated within other
electronic devices.
