N2 - Wireless Local Area Networks (WLANs) are generally deployed in indoor environments such as cafes, offices, and hotels, and therefore, once users enter the WLAN coverage, they tend to stay there in a longer time. That is, in the WLANs which we call double coverage areas, population density is higher and mobility is lower compared to the single coverage area. In this paper, we introduce a new parameter, representing the difference in mobilities (or populations) in and outside the WLAN coverages. Then, by extending the previous works in [2,3], we evaluate the impact of user's mobility in WLAN based on call blocking and handoff failure probabilities. Through simulations, we investigate proper preference settings by changing the WLAN load and the user's mobility parameter in a 3 ring-based sector with a WLAN hotspot.
