Wireless Internet is capable of transmitting data for voice, text and video by wireless network, and recently wireless internet industry is one of the most widely issued. It is categorized into two parts: one is mobile internet and the other wireless internet. Wireless internet's major feature are anytime/anywhere connectionable, portable and multimedia service. And, the markets are increasingly bigger than any other time. In this paper, wireless internet standardization and protocols are described.

Wireless internet is embossed the new keyword of IT technology in the world lately. The wireless internet is the architecture, technology and service to be can taken data communication and internet service using wireless device through connecting internet in the wireless environment. These wireless internet technology is extends the scope of using information with the existing wire internet technology. But, It is necessary to be extend supply of quantitative and qualitative for using wireless internet technology efficiently. For these matters, it is efficient to reuse good qualify contents that is serviced on wire environments. Then, in this paper, design and implement the technique of creating con-tents that is made by the method of compounding parts based on the contents automatic reuse technology over the concept of creating new wireless contents.

Studies about wireless internet have been focused on technology issues and few studies were shown in the adoption of wireless internet services. This study uses Technology Acceptance Model in order to understand influencing factors in acceptance of wireless internet services. Reviewing by TAM related studies, this study regards the influencing factors as personal and social environmental dimensions in the case of wireless internet services, and these two factors are used. Two dependent variables-intention and current usage-are adopted for analyzing the effects of the two factors on two dependent variables via mediating variables. The results of this study show that age, frequency of mobile phone usage, occupation, and the recognition level of wireless internet services affected the intention and current usage of these services.

As different from wired internet, wireless internet has limitations due to the following characteristics; low bandwidth, frequent disconnection, low computing power, small screen in user terminal, and user mobility. Also, wireless internet server should be scalable to handle a large scale traffic due to rapidly growing users. Wireless proxy servers are used for the wireless internet because their caching and transcoding functions are helpful to overcome the above limitation. TranSend was proposed as a clustering based wireless proxy server but its scalability is difficult to achieve because there is no systematic way to do it. In this Paper. we proposed a clustering based wireless internet proxy server which can be scalable in a systematic way. We performed experiments using 16 PCs and experimental results show 32.17% performance improvement of the proposed system compared to TranSend system.

Wireless mesh networks enlarge the wireless coverage area by interconnecting relatively stationary wireless routers (mesh routers). As wireless mesh networks are envisioned to provide high-bandwidth broadband Internet service to a large community of users, the Internet gateway, which acts as a central point of Internet attachment for the mesh networks, is likely to suffer heavily from the scramble for shared wireless resources because of aggregated traffic toward the Internet. It causes performance decrement on end-to-end transmissions. We propose a scheme to balance the load in a mesh network based on link quality variation to different Internet gateways. Moreover, under the mesh coverage, mobile nodes can move around and connect to nearby mesh routers while still keeping the connections to the Internet through the best gateway in terms of link quality. In this structure, gateways perform the balancing procedure through wired links. Information about gateways and mobile node's location is distributed appropriately so that every mesh router can quickly recognize the best gateway as well as the positions of mobile nodes. This distributed information assists mobile nodes to perform fast handoff. Significant benefits are shown by the performance analysis.

The purpose of the study is to suggest and measure the ways to activate the use of wireless internet services in university libraries. For this, 1 reviewed the concepts and characteristics of wireless internet and investigated both local and foreign cases on wireless internet service of university libraries, library users' usage status, and their demands. Based on the case study and survey results, I suggest the strategic consideration and active publicity of university libraries, the introduction of the services students more prefer, the development of differentiated menus from ordinary wire internet services, and the consistent financial support of the university authority.

With skyrocketing number of people who use smartphone, the technology of wireless internet that is mobile-phone, Wi-Fi, Wibro, HSDPA has been developed remarkably. The environment that one can use wireless internet easily and inexpensively anywhere has been made. So, the customer of railway have needs and desire that could use the wireless internet network as travelling in rolling-stock. Although KTX, KTX-II and some subway agency has built-up wireless internet network and serviced it, it's closed infra and inconvenient environment has been criticized. So, we survey the wireless internet network that is serviced at present and the way to build wirelee internet infra to satisfy the needs of customers.

In this paper, we discuss about mobile Internet security. The past few years have seen unprecedented growth in the number of wireless user, applications, and network access technologies. Wireless Internet is similar to wired internet, but it has some constrained wireless environment. So many internet technologies for wireless are developing now

This paper starts by describing the wireless internet service as a new function in the internet age. It then discusses the usefulness of wireless internet for improveing library information service. Recently the use of wireless internet service, as a major internet service in the future, has been rapidly increased because it can be provided various type of information using individual's cellulasphone without the time and space restrictions. Therefore, wireless internet service will be of great use for decentralization and rapidness of library function as well as improvement of user service by providing various interface of information retrieval.

Until now, most of the studies about the internet service have focused mainly on the adoption of on-line(wired) internet services, while there have relatively been very few studies about the adoption and usage of wireless or mobile internet services. The generic model explaining the adoption behaviors of wireless internet services has not been made yet. Previous studies of that area is not so easy to find. The purposes of this paper are two-folds. The first is to find the factors affecting the users' intention and commitment behavior of mobile internet services. The second is to find the relative importance of the factors in users making decisions about users' usage intention and commitment behavior. In the theoretical part of this paper, the precedent studies concerning the technology acceptance model and the theories of on-line internet services adoption, the theories of the mobile internet services, are reviewed and analyzed.
