                                               ABSTRACT
            Rapid evolvements of mobile broadband application services have attracted much attention
            from business owners and executives in recent years. However, researches have shown that
            numerous challenges and obstacles are involved in the successful implementation of a
            mobile application service. Therefore, a meaningful implementation model is needed. By
            looking through related works and relative case studies, this paper will propose a working
            implementation model for mobile application services. The paper will start by studying a
            Mobile-Customs (M-Customs) case based on Wireless Personal Area Network (WPAN)
            and Wireless Wide Area Network (WWAN) backbone networks. The paper will then
            define the project’s critical success factors, and in the end, formulate an implementation
            model for mobile applications accordingly. The paper will also recommend a future
            M-Customs service that uses WiMAX as its major communications technology framework
            based on the experiences gained from testing new technologies in a 3G-based “Living
            Labs” environment.

Description: WPAN ( Wireless Personal Area Network Communication Technologies ) is a wireless connection to the personal area network. It is used in such as the telephone, computer, ancillary equipment and a small range ( personal area network working range is generally within 10 meters ) within the digital assistant communication between devices. Support wireless personal area network technologies include: Bluetooth, ZigBee, OC band ( UWB ), IrDA, HomeRF, the Bluetooth technology in the wireless personal area network used in most widely. Each technology has only been used for specific uses, applications or fields to play to the best effect. In addition, although in some respects, some techniques are considered in the wireless personal area network space in competition with each other, but they often each other is complementary.
