:: 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
By Prof. Tho Le-Ngoc,
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.

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.

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.
