In this paper, the beacon signals of WiFi doppler frequency detection based WiFi-AP was designed with the subcarrier between a transmitter and a receiver of WLAN(wireless LAN). We can use such signals to identify human moving as an antenna array and tracking of RF beam. This wireless security services with the combination of WiFi doppler frequency and adaptive beacon time signal was proposed for wireless detection and motion based services.

최근 무선 인터넷 시장이 급속히 성장함에 따라 다양한 무선 인터넷 컨텐츠에 대한 개발 수요가 급증하고 있다. 또한 다양한 인터넷 단말기와 플랫폼을 유연하게 지원할 수 있는 확장성이 추가된 XHTML이 세계적인 표준 마크업 언어로 자리잡고 있다. 이러한 XHTML은 HTML에 XML을 적용시켜 재정의 함으로써, 기존의 유무선 인터넷 컨텐츠 통합과 상호 운용성(interoperability)의 증진을 위한 핵심 기술로 인식되고 있다. 이에 본 논문에서는 XHTML을 기반으로 한 무선 인터넷 언어인 XHTML Basic 1.0과 WML 2.0 문서를 WYSIWYG 방식으로 쉽고 빠르게 작성할 수 있는 무선 인터넷 문서 편집기를 설계하고 구현한다. 설계한 XHTML 기반의 문서 편집기는 문서를 원하는 형태로 표현 가능하도록 CSS와 WCSS를 지원한다.

Wireless LANs are being used in many fields due to their ease of use. The biggest advantage of the WLAN can be said above all mobility. Domestic wired internet service has been saturated since 2006, but wireless internet users have been steadily increasing. However, WLAN has many advantages and characteristics of wireless service. It has a number of security vulnerabilities, and various security related technologies have been developed and applied to solve these problems. On the other hand, security awareness of WLAN users is still insufficient, and security accidents such as personal information leakage occur repeatedly every year. We will study the main weaknesses that can occur in WLAN and suggest security measures from the management level.
