Addressing future mobile network capacity demands through ultra-dense network (UDN) deployment

The global cellular traffic has been on a steady rise since the early days of 2G networks, and the amount of mobile data traffic worldwide has been doubling every year since 2010.

With this annual growth rate trend, the industry experts predict a 1000x increase in the total data capacity demand in future, with some of the experts and network vendors suggesting that the 1000x mark might be reached by year 2020. A significant portion of this demand is likely to come from indoor users.

In order to be able to meet the increased capacity needs, network densification has been identified as a viable pathway for mobile operators to evolve their networks. Network densification can be achieved by either densifying the existing legacy deployments, e.g. by deploying more macrocell sites together with street-level microcells, or by deploying new indoor low-power sites, or both. Ultra-dense deployments, or DenseNets, seek to take network densification to a whole new level, where extreme spatial reuse is achieved by deploying thousands of base station over a certain area. Such dense deployment triggers cost and energy efficiency concerns for mobile operators.

MSc. Syed Fahad Yunas has studied and analyzed DenseNets, from an alternative deployment strategies’ perspective, in particular, when individual densification solutions are pushed towards their capacity limits. The performance evaluations of different deployment solutions are based on system-independent approach, integrating not only the classical capacity and spectral efficiency aspects, but also energy- and cost-efficiency perspectives. The energy-efficiency aspects are seen particularly important when moving towards the era of green communications, under clear trends and incentives to save energy at all levels of society.

Overall, the dissertation aims to provide technical insight and understanding of DenseNets, their performance limitations in the long run, and critical conclusions on the choice of deployment scheme that can assist mobile operators in deciding the best evolution strategy for their network in the future.

Public defence of a doctoral dissertation on Friday, 9 October

The doctoral dissertation of MSc (Tech) Syed Fahad Yunas in the field of Wireless Communications entitled “Capacity, Energy-Efficiency and Cost-Efficiency Aspects of Future Mobile Network Deployment Solutions” will be publicly examined at the Faculty of Computing and Electrical Engineering of Tampere University of Technology (TUT) in room TB224 in the Tietotalo building (address: Korkeakoulunkatu 1, Tampere, Finland) at 12:00 on Friday, 9th of October 2015.

The opponent will be Associate Professor Mario Garcia-Lozano (Universitat Politecnica de Catalunya, Spain). Professor Mikko Valkama from the Department of Electronics and Communications Engineering at TUT will act as Chairman.
