| In the Mobile Internet Era, WiFi module has become a standard configuration of mobile internet terminals such as smart mobile phone and tablet PC. It has fostered a large number of people in the habit of surfing net by WiFi. How to seizing the internet entrance via WiFi has become a research focus of the internet industry. In this project, we develop a smart wireless Access Point device base on embedded systematic technology. This device could transform 3G signal to WiFi signal and establish one minitype, efficient and free Wireless Local Area Networks. It can work in the circumstance with an absence of cable network such as bus or boat, and attracts users surfing the internet in fragmented time.In this project, we use Atom D525 microprocessor which base on X86 architecture to be the core of hardware module. The mainboard integrates WiFi, 3G and storage module. We design ITPS electric power transforming module in order to accommodating the vehicular environment. The terminal uses Ubuntu operating system as software platform, and uses Wvdial to control the 3G dialing. The wireless network adapter could imitate wireless AP with soft-AP technology. The backstage authentication and management system can control the internet entrance by using redirection software as well as WiFidog and Authpuppy, and capture webpage information from the network by using simple web crawler technology, which the information is going to be integrated on the local Apache website server on the purpose of providing an efficient information platform.The demo could fix on the bus and provide WiFi sevice to those who need to surfing net. It can embed advertisement into the local homepage to realize potential commercial value or public welfare ad. Finally, reserved interfaces in the demo make it possible to extend function by installing extended modules such as sensors or camera, then it could be acted as smart data node in bunches of fields such as internet of things. |
