Description
Summary:This paper shows an experimental development to identify the phenomenon called pilot pollution and observe its impact on Quality of Service (QoS) of 3G networks. The analysis is based on coverage maps, created from spot measurements obtained with specialized measuring equipment, able to obtain information based on the Key Performance Indicator (KPI) of the WCDMA system, called Common Pilot Channel (CPICH). Consequently, we analyze various performance indicators that allow us to identify the signal problems. Then, using a Geographic Information System (GIS), identify the problem areas, overlapping coverage and trend in signal propagation.
