This paper provides a complete solution for building related propagation, starting by validating the Lee In-building model [1-3] for the single floor scenario. Then how the enhanced Lee In-building model performs in inter-floor and inter-building cases are discussed. Measurement data were collected from 2.4G WLAN developed systems installed in many different floors in two different buildings which are connected with a corridor. The data are from multiple single floor measurements, inter floor measurement and inter building measurements. The FDTD and Ray Tracing models [4-9] was used to validate the measured with the Lee model. The results show that the Lee model outperforms the FDTD and Ray Tracing models in both speed and accuracy. The propagation environment is quite unique and challenging for this deployment. The Lee model was used to optimize the coverage and minimize the interference while fine tuning radio parameters (antenna types, ERP, down tilt) to improve system performances. The net results were continuous connectivity with smooth roaming and high throughput which provided a different experience for users. [ABSTRACT FROM PUBLISHER] |
