:: Key Notes
By Prof. Dr. Phuoc TRAN-GIA,
University of Wuerzburg , Germany
Currently, we are witnessing fast-moving activities towards next generation network. On the one hand, a transition from multi-service networks to multi-network services can be observed, together with the move of the service creation process and content location to the edge of the network. Unlike classical services, which are designed and deployed by network providers, edge-based services are created by the users, where numbers of users rapidly increase, force the network to react (Skype, Youtube, Myspace,…) and emerge to business-cases. Contents of such content delivery platforms are rather created by the user than offered by the network provider. These issues have to be properly considered in the design of Next Generation Internet. The talk will address the issues of interaction between network design and service evolution, which emerge to the concept of Quality of Experience, opening a fast-growing research field. The talk will also highlight research initiative in the US , in Europe as well as in Asia towards Future Internet.

Advances in Broadband Access Communications
Department of Electrical and Computer Engineering of McGill University, Canada
Broadband access communications have been continuously developed with many advances in response to increasing demands of multimedia services and applications. Broadband communications systems are generally power- and bandwidth-limited while the communications channels are characterized by their frequency-selective fading and the presence of noise and interference. Due to the dynamic nature of both transmission media and multimedia traffic, re-configurable and adaptive schemes are of particular interest. Furthermore, in most broadband communications systems, interference is the major performance-limiting factor and interference mitigation can be more efficiently done by coordination of the transmission and resource allocation between users to minimize mutual interference in a collaborative manner. The talk will provide an overview of new developments/deployments in broadband access communications, and highlight technical issues in dynamic resource allocation and intelligent multi-dimensional signal processing and the evolution from competition, to cooperation and cognition in communications.

Ubiquitous Communications: The Next Wireless
Chair Professor and Head, Electronic and Computer
Director, Hong Kong Telecom Institute of Information
The Hong Kong University of Science and Technology
Over the past
decade, wireless communications has seen an
exponential growth and will certainly continue
to witness spectacular developments due to the
emergence of new interactive multimedia
applications and highly integrated systems
driven by the rapid growth in information
services and microelectronic devices. So far,
most of the current mobile systems are mainly
targeted to voice communications with low
transmission rates. In the near future,
however, broadband data access at high
transmission rates will be needed to provide
users packet-based connectivity to a plethora of
services. It is also almost certain that the
neXt Generation (XG) wireless systems will
consist of complementary systems with a set of
different standards and technologies along with
different requirements and complementary
capabilities that will offer users ubiquitous
wireless connectivity between mobile and desktop
computers, machines, game systems, cellular
phones, consumer electronic products, and other
hand-held devices. A key requirement in future
wireless systems is their ability to provide
broadband connectivity with end-to-end Quality
of Service (QoS), a high network capacity, and
throughput at a low cost.
This talk will
present an overview of the most recent trends along
with the evolution of cellular systems to 4G and the
emergence of long range Wider-Fi networks such as
WiMAX. It will also describe and discuss the
challenges facing the XG broadband systems with a
special interest on cognitive ubiquitous
communications networks, dynamic resource
allocation, especially for MIMO and OFDM along with
cross-layer design and optimization.

Technical marketing manager at QUALCOMM Incorporated
Global demand for
mobile broadband is growing significantly and
continues to outpace availability. Strong, sustained
consumer demand for mobile voice services has
created an enormously successful global ecosystem,
with numerous operators providing services and
vendors delivering products. With significant scale
and maturity, the 3G industry is well-positioned to
deliver mobile broadband to an enormous installed
base of customers, while reaching out to new ones.
3G’s growing scale is leading to more-affordable,
more-capable devices across all market segments.
This fact, in conjunction with growing global
coverage, increases the likelihood that 3G devices
will maintain an advantage over other technologies.
The versatility of 3G systems to support all
IP-based applications with robust QoS is enabling
operators to bring to market a wide range of
creative VoIP and data services. While 3G systems
give the best mobile broadband experience today, it
is also likely that they will continue to do so as
their evolutions introduce class-leading MIMO &
advanced receivers solutions. The talk will give an
overview of the 3G roadmap, its evolution path &
features, and its services & applications. It will
highlight the fact that 3G is, and will continue to
be the best mobile broadband technology.
Keith Hong is a technical marketing manager at
QUALCOMM Incorporated. Keith’s primary
responsibility is to support 3G-related technical
marketing & engineering activities in Southeast
Keith has worked in the telecommunications industry
for more than 10 years and has gained extensive
experience in a wide spectrum of companies across
the value chain. He started his career as a telecom
application programmer, then spent five years
working for mobile carriers, managing their mobile
applications & services businesses. Following this,
Keith worked as a product manager at Ericsson and
helped the company to promote 3G application
platforms & service networks to carriers in
