Site Specific Propagation Prediction Models for PCS Design and Installation
نویسندگان
چکیده
This paper presents new site specific propagation prediction methods for emerging personal communication system (PCS) services which will offer high capacity in urban settings. The propagation prediction models, composed of three dimensional dif· fracti"on and ray tracing, are being implemented as software tools on SUN computer workstations. A Geo'graphical Information System (GIS) software package is being used to interface building and terrain data with the propagation prediction programs. Early work at Virginia Tech's Mobile & Portable Radio Research Group (MPRG) show that the predicted signal strengths are within a few decibels (dB) of average measured signal strengths for some test cases [1], [10].

This paper studies the impact of surrounding buildings on path loss and multipath delay spread for Personal Communication Services (PCS) operating inside of buildings. Measurements conducted inside three large office buildings in the San Francisco Bay area provide an extensive database for propagation models at 915 MHz and 1900 Wlz, and show variability in path loss and delay spread caused by m...

OBJECTIVE To perform a more sophisticated analysis of previously published data that advances the understanding of the efficacy of pedestrian countdown signal (PCS) installation on pedestrian-motor vehicle collisions (PMVCs), in the city of Toronto, Canada. METHODS This is an updated analysis of the same dataset from Camden et al. A quasi-experimental design was used to evaluate the effect of...
متن کاملSite-specific Propagation Prediction for Pcs System Design
Wireless communications has been plagued by our inability to fully understand how radio waves behave in complicated channels. In the past, anti-fading and anti-multipath techniques such as diversity and equalization have been used to combat the random small-scale fluctuations induced by radio channels, and propagation models were developed to help the communication engineer design radio links i...

It is undeniable that instability plays a significant role in the design of pipelines. Local buckles induced by excessive force on specific part of pipeline can locally reduce the collapse pressure of a pipeline and cause local failure. Periodic placement of buckle arrestors along the pipeline can ensure that collapse only effect the length of pipe between two arrestors on either side of the in...
