In this paper, the impact of the high speed packet access (HSPA) indoor network on the macrocell HSPA performance is studied based on field measurements. The indoor network configuration and the indoor antenna locations were varied for the measurements. The performance evaluation was based on data throughput and link quality parameters in downlink and in uplink. According to the measurement results...
The aim of this paper is to present and propose different multi-antenna cell constellations based on outdoor distributed antenna system implementation. The idea of the outdoor DAS is to reduce interference in dense urban areas in order to achieve very high signal-to-interference-ratios (SIR) which defines the data throughput available to the user. Moreover, the SIR distribution over the network coverage...
This paper provides a performance comparison of two macrocellular topologies from the point of view of RF-repeater deployment. The numerical, system level, performance estimation was done in the downlink direction using high speed downlink packet access technology. In addition to a detailed repeater model, a distance dependent orthogonality model for wideband CDMA codes was included in the performance...
This paper discusses the use of high altitude platforms, HAPs, to provide mobile communication services to on-ground customers. The paper explains the behavior of UMTS radio network in a situation, where the service is being provided by HAP and terrestrial base stations in a disaster scenario. In the disaster scenario, a set of adjacent terrestrial cellular base stations in the middle of the network...
