One example of heterogeneous networks include deployment of outdoor low power pico eNBs in existing macro-layer networks. Placing these within the coverage area of macro eNBs introduce several challenges in terms of assuring low interference levels while at the same time improving the performance of the users. In this paper we focus on the comparison(More)
One of the key enhancement elements of next generation LTE networks is the deployment of relays. Relays provide added performance gains in the form of enhanced coverage for mobile UEs situated in poor coverage areas. Relays provide coverage gains in high shadowing areas and also help reduce power consumption at the UE terminal by enabling a better(More)
J. Borowiecka-Jamrozek, J. Lachowski, Kielce University of Technology, Poland This paper deals with the modelling of the mechanical properties of materials used as the matrix in diamond tools. Saw blade segments were fabricated by combining various metal powders with diamond crystals and then hot pressing them. After consolidation, the specimens were tested(More)
