The paper investigates the use of Radio Environment Maps (REMs) as a tool for Interference Management (IM) in two-tier cellular networks comprising macro- and femto-cells. The REMs are databases that provide, through different instances distributed over network elements, a variety of network- and user-related context information for improving IM and Radio Resource Management (RRM) procedures. In this...
Wireless systems are becoming increasingly complex with the coexistence of multi-frequency, multi-technology, multi-service and multi-layered systems. In this context, there is a strong need for developing technologies for optimizing future wireless systems in terms of cost, Quality of Service (QoS), resource management and spectrum efficiency. Key enabler for such technologies is providing wireless...
We study the influence of the configuration and distribution of transmitters on radio environment maps. We adopt a statistical approach, treating total received power as a random field characterised with second-order statistics. Using extensive simulations we characterise the effects of changing node counts, distribution of node locations, transmit powers and propagation environments on the studied...
