Abstract
One of the major problems in Wideband Code Division Multiple Access (WCDMA) Radio Access Network (RAN) is interference; which reduces the signal quality of a cellular network system. Most cellular network service providers use either frequency planning or code planning techniques to analyze the interference and assign frequencies and codes based on measurement reports from network statistics.
This research presents a bright analysis of one of the main method for reducing interference in WCDMA technology using some Key Performance Indicators (KPIs) of a functional cellular network service provider in Nigeria.
From the analysis and results it was visible that using the Power Control Approach (PCA) the interference on uplink transmission in cellular networks will certainly be reduced. Hence, the signal quality would be improved and optimization of the network services could be actualized. Consequently, a better Quality of Service (QoS) would be guaranteed for the generality of the subscribers.
