| Summary: | 碩士 === 國立雲林科技大學 === 資訊管理系碩士班 === 92 === There are a lot of different differences between wireless network and wired network, among them (1)Smaller wide (2 ) unstable transmission media frequently (3)The restriction of the hardware equipment, it is not so easy to realize to transmit that the instant multimedia that makes on the wireless network is audio-visual. It is neither at present for action development, communication of network nor the getting wide and getting more enough to let by multimedia materials more already frequently in network not wireless in on transmit, if 802.11b offers the transfer rate of 11Mbps, the technology with the direct array exhibition frequently (DSSS ), operates and takes frequently in 2.4GHz. And is holding action equipment, for instance Pocket PC , PDA , Notebook ,etc., after matching. the wireless communication mould group, can let information flow by network through internet too, so materials type that transmit attitude confine characters to only already, various kinds of multimedia data materials can also be transmitted , so this researh has made use of such a characteristic to develop the instant image on the action device to transmit and serve, hope to solve more our bottlenecks in using the action device with the characteristic transmitted immediately
