Second International Workshop on

Fundamental Capacity Limits for Wireless Communications

University of Surrey, Guildford UK

In the past, wireless systems were designed to accommodate a large number of voice and/or low-data-rate users. With the emergence and continuing growth of wireless data services, the performance of a system is no longer determined only by the number of users it can support, but also by its ability to concentrate high data rates at localized spots. Thus, in the age of wireless data, user data rates and spectral efficiency surge again as the important metrics.

Mobile VCE, a group of academic institutions in UK and leading industrial members, has launched a quest for fundamental limits to the spectral efficiency of communication networks. The objective of this quest is of high importance to both network operators and equipment manufacturers as they make decisions about the investment in new technology.

In the context of this project, the fundamental capacity limits of cellular systems have been investigated over the last 18 months. Using known information theoretic formulations for joint processing cellular architectures as a starting point, the theoretical models have been extended to more realistic systems, incorporating multipath and shadow fading and distributed users within a variable density cellular system. The effect of diversity and power gain, obtained using multiple antennas and sectorisation of cells, is also investigated. Both uplink and downlink of cellular system are studied with reasonable relevance to real-world system models. Effect of correlation on shadowing coefficients and multipath fading coefficients is also considered.

Programme Focus

This workshop is a sequel of the first workshop where the awareness of the fundamental capacity limits on multi-user and multi-cell wireless configurations was raised. The objective of the current workshop is to create a forum for the presentation of the project work and the discussion of future research directions among well-known academics and international industrial key-players.


By bringing together different industrial and academic partners, the workshop will contribute towards a constructive dialogue on the information-theoretic limitations, options for reliably estimating these maximum limits, and the scope and validity of the recent results for the fundamental capacity limitations.


The participants from the academia will have a chance to communicate their current and future research interests with the industry. The industrial sponsors shall also engage actively in the panel discussions with the invited academics. This will aid all the participants to gain a better understanding of physical limits in real-life engineering and thus, shape a clear vision on future research themes that will lead to more efficient wireless communications. This forum will provide an opportunity for the industrial participants to influence the direction of the research in the area. This will hopefully bridge the gap between the academic and industrial perspectives on fundamental capacity limits.


Programme Scope

This workshop will attempt to present the state of the art in research carried out to find the capacity limitations in multiuser networks, where a large number of interconnected base stations are allowed to communicate with a large number of terminals by following a cellular approach. It will provide an insight into the appropriate methodologies that need to be addressed with emphasis on the following key topic areas:


         Information theory and practice

         Multiple access techniques, cellular system design, and ad-hoc wireless networking

         Shannon capacity of multi-cellular and ad hoc networks

         Spectral efficiency of wireless systems

         Key factors that determine the capacity limits in wireless networks, e.g. number of antennas, interference management etc.
