Coexistent with that trend, mobile broadband technologies have been developed rapidly to support next generation mobile communication network advancements. It will allow the users to enjoy faster network transmission with higher data rate and better quality of service. However since the service availabilities of mobile broadband connection to internet service providers are still insufficient, many users are relies on old mobile communication technology. Therefore based on this fact, it is important for allowing the users to recognize the quality of their mobile network connection. Addressing that issue, this study develops a wireless networks quality measurement system based on Android platform. It covers two wireless access technologies 3.5G and WiFi, which used commonly in mobile phone network connectivity. Active and passive measurement approaches are combined in order to analyze network latency and download-upload speed. The system is also equipped by network background traffic monitor and the status of Android system. Finally with this proposed measurement methods, the system can show more QoS parameters data in aiming the users to recognize network connection quality. The proposed method is compared with TTC speed test, Speedtest.net and NTU Network Speed Test, and through qualitative analysis results, the proposed measurement method can provide better measurement functionalities.
