The wideband channel measurements at 580 MHz, 2.35 GHz and 4.90 GHz have been performed in the urban micro- and macrocell scenarios in the cities of China with multiple-input multiple-output (MIMO) channel sounder. The measured cases include line-of-sight (LOS) and non-line-of-sight (NLOS) propagation. Statistical results and comparative analysis for both scenarios are presented in this paper, including...
A simple technique to estimate the position of a mobile node inside a building is based on the Received Signal Strength (RSS). In previous publications, we investigated the effectiveness of using circular array antennas and beamforming in order to enable an access point to estimate the position of a mobile inside a building. We also discussed the feasibility of using model-based radio maps to reduce...
Relaying as a means of in-band backhaul has the potential to extend the coverage of Beyond 3G networks, enabling the expected high data rates of these networks to be delivered without increasing the density of traditional macro base stations. Assessing the performance of relaying is not simple, since traditional metrics fail and the performance depends strongly on the actual deployment. The current...
In the present work we study different coverage strategies for the deployment of mobile radio system in urban areas, with a particular attention to environmental aspects. The case study is a real urban deployment, in the city centre of Bologna. Both macrocellular and microcelluar coverage strategies have been analysed in order to obtain optimised coverage that guarantees a good service quality with...
