(There are many "network blind spots" in the traditional wired campus network. For example, how to connect to the Internet in many venues and facilities that are not suitable for network wiring, such as libraries, large conference rooms, and gymnasiums? How to break through the restrictions of network nodes/points and realize the problem of multiple people surfing the Internet at the same time in classrooms and laboratories in schools, in corporate offices, conference rooms, factories and other occasions? In order to let more schools interested in WLAN have a more comprehensive understanding of WLAN technology, especially engineering construction, we have written this white paper, which details the technical standards, security, campus use environment and mode of WLAN. introduce. How to build a WLAN in a campus is the focus of this book and the original intention of everyone writing it. After a brief introduction to the basics of WLAN in the first chapter, we quickly enter the topic of "building a network", and the second chapter provides a detailed reference in this engineering aspect. Chapter 3 introduces the wireless environment and WLAN related equipment, so that the user can fully understand the requirements and characteristics of the installed equipment, which is very important for maximizing WLAN performance and providing the best user experience. Compared with the wired network, the network security and management of WLAN are the two parts that attract the most attention. The fourth chapter introduces the security protection technology and management strategy of WLAN.)
