The significant penetration of the WiFi technology in the last decade and the lack of solutions for coordinated and efficient interference management between WiFi networks in unlicensed bands often lead to poor spectrum utilization and network performances. The synergy between Radio Environmental Maps (REMs) and Radio Resource Management (RRM) can offer a viable solution for so called Smart-WiFi that...
The heterogeneity in cellular networks that comprise multiple base stations' types (i.e. femto and macro) imposes new challenges in network planning and deployment of future generation cellular networks. The chosen radio resource management techniques, such as dynamic sharing of the available resources and advanced user association strategies, determine the overall network capacity and efficiency...
Cognitive Radios (CRs) are enablers of opportunistic wireless spectrum usage. Their key roles (such as spectrum sensing, spectrum sharing etc.) provide more efficient spectrum utilization embedding higher degree of intelligence in wireless systems. This paper gives an overview of the most important CR characteristics and the standardization efforts in the area. Additionally, the paper reports on measurements...
