Research and development of technologies that address the challenges of predicted growth in mobile connections and traffic volume is well known. A major challenge is the cost of meeting the objective, in terms of both infrastructure and deployment. Today, lack of dynamic control across wireless network resources is leading to unbalanced spectrum loads and a perceived capacity bottleneck. The solutions...
Heterogeneous networks constitute a promising solution to the emerging challenges of 5G networks. According to the specific network architecture, a macro-cell base station (MBS) shares the same spectral resources with a number of small cell base stations (SBSs), resulting in increased co-channel interference (CCI). The efficient management of CCI has been studied extensively in the literature and...
In currently deployed wireless networks, the lack of dynamic control across wireless resources leads to suboptimized and unbalanced spectrum loads, especially in below 6GHz bands, which in turn creates a (perceived) capacity bottleneck in end users. This issue can be addressed through the adoption of the eDSA (extended Dynamic Spectrum Access) paradigm, which consists of enhanced resource management...
The concept of this article is to design, develop and validate mechanisms for deciding on the creation and set-up of opportunistic networks based on moving access points (MAPs) for mobile client nodes. Mobile client nodes can be smart/connected cars in civilian use cases, or any kind of operational vehicles and/or robots/drones in military cases. Opportunistic networks will be formed in an ad hoc...
This paper presents the vision and some early results achieved by the EU-funded SPEED-5G project which is part of 5G PPP [1]. It addresses some key challenges of future 5G systems, i.e. a 1000 times higher capacity, a much lower latency and a much improved user quality of experience compared to currently deployed networks. The devised new technologies are based on densification of small cells, exploitation...
