| dc.description.abstract | Because of the higher speed of 4G mobile network, more and more people like to use it. It can’t promise bandwidth by multi-users. If the lease of base station expires, the 4G base station might be removed. The 4G signal will become weakening and unstable. On the other side, the biggest advantage of physical line is the network speed. It can’t be affected by multi-users, and the failure rate is also low. So there is a new business model of physical line and wireless network sharing in the market for free by clicking on the ads and watching videos. In this research, we hope to realize this three-win model for users, network providers, and merchants by providing free wireless network services. Users can automatically log into the wireless network through the APP, and access to campus-related service systems. We can use this application to collect wireless signals, GPS location information, and the information collected to study and analyze the online quality of the wireless base station.
We mainly design a free wireless network platform in this research. Through this NCUFree wireless network, we develop the application for mobile devices. Compared with past research, the original only provides Android platform. We add the iOS platform application for users. Through the web system architecture redesign, it makes that program development and update programs better convenient, we do not have to replace Android and iOS programs every time. Second, we have developed a management back-end interface to make it easier for management to use the system. The NCUFree mobile application also integrates common application services on campus, including NCU mobile Web Page, Portal-related Service System and NCU Parking Search System. It makes students and faculty easier to use the campus system. At the same time through the NCUFree mobile application, we can collect wireless signal values, GPS positioning return location, and the success and failure of logging into the NCUFree system to cross-verify the accuracy of the bad signal location.
