The demand of wireless access in anywhere and anytime drives the deployment of Wi-Fi hotspot. Multiple service providers may deploy the Wi-Fi hotspot in the same area to response to the users' needs. Channel assignment for the access point becomes the challenging problem, especially in the situation that other service providers do not provide full cooperation. Channel assignment of APs need to be...
A misperception that encryption largely degrades performance of the system may have discouraged many IEEE 802.11 WLAN infrastructures from enabling wireless signal encryption. In particular, there have been several recent research studies suggesting that encryption could noticeably degrade performance of WLAN systems by as much as 20%. Since the 2.4 GHz frequency spectrum used in the IEEE 802.11 WLAN...
In this paper we propose the integrated solution for detection and counterattack the rogue access points. Classification of rogue access point and related risk assessment is analyzed. Rogue detection algorithm is also proposed. Our proposed solution is effective and low cost. It is designed to utilize the existing wireless LAN infrastructure. There is no need to acquire the new RF devices or dedicated...
One of the reasons that many IEEE 802.11 WLAN infrastructures do not utilize signal encryption may be related to the general perception that encryption largely degrades performance of the system. Especially, there have been several recent research studies suggesting that encryption could noticeably degrade performance of WLAN systems by as much as 20%. Here, we note that the 2.4-GHz frequency spectrum...
