With the improved cost and performance of Wireless Local Area Network (WLAN) systems and the growing availability of standards-based solutions, WLAN services and acceptance have mushroomed in both research and application domains. In the technological world as well as this paper, most concerns surround the security and quality of service of WLAN. The WLAN research paradigm used in this paper takes the form of empirical measurements of Radio Frequency site surveying modelling. This paper presents the design of Hong Kong's most comprehensive longitudinal WLAN experimental study, code-named Project-WLAN, and the various implications associated with the findings.
