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.

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.

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.

To understand and forecast the wireless internet market in Korea, we will analyse the network externalities in wireless internet market into communication network externalities and hardware/software network externalities. The wireless market has two competing streams, one is mobile internet and the other is wireless fan internet. Both are characterized by strong network externalities which lead to increasing return to stale. Mobile internet is supposed more suitable for communication and WLAN for data. However these two system will compete in some area, and the critical factor to deride the winner is supposed to be the network externalities as in so many other high-tech industries had showed.

Everyday demand of wireless internet is increasing. Security problem is certainly resolved for wireless internet activation. Especially problem is only wiretap in mobile communication with voice, but problems, user authentication, data integrity guarantee etc., are resolved in data-services that have commercial transaction over simple data information service such bill, banking. Necessity of wireless PKI that can offer security service likely in wired environment is requested for offering security service in wireless environment. For offering security services, confidentiality, integrity, non-repudiation etc, that of offered in wired environment in wireless environment, first it must construct wireless PKI infrastructure and do service activity. This paper analyze various wireless internet technology for offering safe wireless internet service and wireless PH standards. Performance Result of this paper expect activity of safe wireless PH service and activity of electronic commercial transaction used wireless internet such banking service, bill transaction, online shopping.

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.

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.

In this study, current status of technology and realities of usage on wireless Internet for educational applications were examined, and based on related studies and case analysis, 'Matrix OX Quiz' that can be applied at present time was designed and built. Main characteristics of this system are as below: Firstly, an attempt was made to achieve educational effect by offering educational contents that are suitable for wireless Internet era, breaking away form limitations on time and space with previous wired Internet. Secondly, mobile phone was selected as the wireless Internet terminal considering the current wireless Internet usage environment and technology, and improved convenience by supporting WAP form Markup language used by SK telecommunications with the most enrollment at present. Thirdly, self-directed learning capability of students can be improved through lessons utilizing wireless Internet. Especially, responsibilities for teaming can be increased through lessons utilizing wireless Internet, and abilities needed for solving immediate problems can be developed. Therefore, the educational contents built in this study should have sufficient educational effects if wireless Internet becomes widely spread and most students can easily use it in near future.

Nowadays, various wireless internet contents are serviced in a cellular phone. However, because of the memory limit of the cellular phone, you should delete the wireless internet contents periodically. Also it has been quite inconvenient to move the existing data to a new cellular phone. In this paper I proposed MobileFolder to reuse wireless internet contents and provided a simple client application in a VM environment.

The requirements to use high speed internet under wireless environment are increased. To satisfy the requirements. the WiBro service combining high speed of wired internet service with mobility of wireless internet service will be launched as an alternative. This paper reviews and analyzes its overview, features, and comparison with existing mobile internet and wireless LAN in the information providing aspect. This paper also proposes how to adapt mobile information service and how to satisfy the requirements to construct mobile library based on the WiBro service. With the current problems in mobile-based information services provided by libraries. especially this paper proposes information service areas. considerations to provide information services, and service provisioning method based on the WiBro service.
