| Popis: | Future indoor wireless systems must have a high level of performance in terms of quality and capacity. High performance systems require careful deployment of access points. However, there are relatively few degrees of freedom available to the system planner during the deployment of these systems. The antenna type, location and orientation need to be carefully selected to achieve high performance, as measured path losses can be significantly affected by the antenna's radiation characteristics. Most studies of antenna deployment effects on indoor wireless system performance make use of radiation patterns measured in free-space conditions. In practice, antennas will be mounted on complex inhomogeneous dielectric structures such as cavity walls (comprised of two drywall layers with timber or steel supporting frames). This paper reports results of a research project investigating how complex cavity wall structures influence the radiation characteristics of access point antennas, and to what extent any such effects could be exploited to improve system performance. |
