Ubiquitous services are an inevitable trend of our future. Nowadays, there are many wireless technologies that can be used and provide services to mobile users. If we can integrate their respective advantages and design a system to create an ubiquitous multimedia environment, it will be very convenient for people. In this paper, we will use Zigbee (IEEE 802.15.4), NFC (Near-Field Communication), Bluetooth (IEEE 802.15.1) and Wi-Fi (IEEE 802.11) to design a system that is able to support mobile devices unremitting data transmission services. In addition, each mobile device (MD) can automatically switch between multiple wireless interfaces according to the proposed policies in terms of high bandwidth and power saving. According to the experimental results, the proposed method can demonstrate its advantages.
