In this study, the relationship between network access quality and RF quality parameter in the wireless networks which have different characteristics from wired networks when the dedicated terminals being connected to the high speed wireless data networks (in other words, broadband wireless access service networks) such as CDMA IX EV-DO, WCDMA (HSDPA), or Mobile WiMax (WiBro) is analyzed. Also, this study proves that the analysis in connection with the users' service usage patterns is available. This was possible by constructing and operating the broadband wireless access service Monitoring System (BWA Monitoring System) that collects user data in connection with the CM (Connection Manager) program of the respective terminal. And, analysis regarding the users' network usage patterns was possible which could be utilized as reference in creating new business models; furthermore, the study shows that the SLA (Service Level Agreement) in the wireless network sector can be proved.
