3-D double-directional radio channel characterization for urban macrocellular applications 总被引:2,自引:0,他引:2

We measured the spatial properties of the three-dimensional (3D) double-directional radio channel in urban macrocell environments separately at both ends of the link. In this paper, we study propagation conditions pertaining to reception and transmission at the mobile terminal, measured using a wideband channel sounder and a dual-polarized spherical antenna array. We were able to refine the results of the measurements conducted at the base station, and extend the study to full double-directional 3D channels. Individual propagation paths could be identified precisely, in some cases even considerable scattering from lampposts was observed. Our results show that over-rooftop-dominated propagation often occurs via building roofs with LOS to the base station antenna, acting as strong secondary signal sources. Based on measurements along continuous routes we demonstrate that the dominant propagation mechanisms can vary considerably when the mobile moves in the environment. We also present typical directional properties of the 3D radio channel at the mobile terminal in urban macrocell environments characterized by street canyons, showing how the angular distribution of energy is correlated with the excess delay. 相似文献

With the increasing demand for cheaper and better wireless communication services from customers, and the tendency to move toward smaller cell sizes, it is becoming very important to optimally design the cell geometry and deploy the minimum number of base stations to provide maximum possible coverage. We consider how to optimally determine the locations for the placement of base stations for a wireless system in an urban setting, given the cell coverage. An algorithm is presented that determines the optimal locations of the base stations without performing an exhaustive search. Using this algorithm, a 20-25% decrease in the number of base stations required has been observed for simulated environments. The computational complexity of the proposed algorithm is also discussed 相似文献

The effect of electromagnetic radiations from wireless cellular telephony systems on human health has been intensely discussed.
As a result, and despite the lack of evidence on any adverse effects, recent regulations make network planning even more difficult.
Base stations, even those covering urban areas, tend to be placed at suburban locations (in this paper we cite some examples
of related local regulations). In these cases, mobile stations inside urban locations must raise their power transmission
level to reach suburban antenna placements. Therefore, users may complain of a higher radio exposure. In this work we propose
a feasible solution to reduce electromagnetic activity from mobile communications equipment and to cope with restrictive placement
regulations. To accomplish this goal, a suburban base station is divided into an active part (transmitter) that is kept at the suburban location, and a passive part (receiver), which is moved inside the urban area. Thereby, the power received from the base station can be considered negligible inside
the urban area (since the active part is far away), and mobile terminal/stations transmit lower power levels (since passive
receivers are close to them). We justify the solution in the context of the globally available GSM networks, both analytically
and with empirical and simulation tests. The results in this paper reveal that our approach reduces electromagnetic levels
and improves uplink quality, which reaches typical levels of urban base stations. 相似文献
