This paper presented a research on the Mobile wireless communications which focus on w wideband Code Division Multiple Access (WCDMA) system. It is known as one of the most advanced form of human communications recently. The research focuses on Soft Handover (SHO) where the User Equipment (UE) is connected simultaneously to several Node B(s) on the same frequency. The objective of this paper is to evaluate the differences of Soft Handover parameters of addition and drop windows impacts on network performance. The network performances will be focus on the SHO transport network overhead. The drive test was conducted to collect real measurement data in live UMTS network. Data were collected and analyzed. Simulations were done to examine the behavior of Soft Handover events. It is shown that the addition and drop windows have decisive effects on the SHO transport network. Thus, the parameter for addition and drop windows setting should be planned properly to mitigate the SHO transport network overhead and effect. This research would benefit the network administrator to manage and realize users on the performances in the mobile wireless communication especially for WCDMA system.
