This paper presents experimental results of a coverage analysis of a WCDMA network in the 850 MHz band in an urban environment. Obtained coverage estimation maps are based on statistical interpolation method named Krige. Key performance parameters used in this paper are the CPICH and Ec. The results could be used to identify problems and help to optimize cell coverage and capacity to the Service Operator in a given service area. WCDMA (Wideband Code Division Multiple Access) is a technology of third generation 3G that increases data transmission rates by broadening the signal at the air interface through the Multiple Access Code Division Multiplexing instead of Time Division used by GSM systems.
