The regulatory landscape is changing towards more flexible spectrum management schemes. Such schemes are expected to make additional spectrum resources available and lower the spectrum access barriers. Emerging spectrum authorization schemes such as secondary access (TV White Space) and Licensed...

Cooperation between Mobile Network Operators (MNO), as competing entities, has become a solution to overcome lack of revenue by reducing expenditures during recent years; where theses cooperation patterns consist of horizontal and vertical models. As much as all these models apply in macrocell...

Cooperation and collaboration with either competitors and/or other actors in the ecosystem seems to become a relevant method for Mobile Network Operators (MNOs) in order to decrease costs and boost revenues at the same time. But, there are always risks and imperfections in front of such models...

Mobile operators nowadays tend to deploy dense heterogeneous layers of 3G and 4G networks in outdoor and indoor environments by adding more macrocells and smallcells (e.g. microcells, picocells and femtocells) in response to the increasing subscriber demand for coverage and capacity. The main...

Nowadays, the increasing mobile data traffic adds extra pressure on the almost congested mobile networks. In order to meet the new demand, mobile operators have to improve their networks but as revenues are not expected to rise, they have to add extra capacity in a cost-efficient way. The...

Internet of Things is an inherently multi-disciplinary area, as mobile connectivity, sensor device technologies and cloud solutions make strong impact in a multitude of applications in diverse sectors. In this paper we study some technical solutions, business models and behavior aspects of IoT...

Despite a continued build-out of mobile networks, both mobile network coverage and capacity problems in rural areas are increasing. This counterintuitive situation is due to the exponential growth in mobile data usage, the long inter-base station site distance in rural areas and the increasing...
