Although Wireless LANs market has grown tremendously in last few years, their enterprise deployments have been fairly limited. From manual site survey process to ensure signal coverage at all locations, to the well known security issues in original standards, there have been several deterrents to a

Abstract: The physical locations of clients and access points in a wireless LAN may have a large impact on network perfor-mance. However, today’s WLAN management tools do not pro-vide information about the location of clients apart from which access point they associate with. In this paper, we

This paper introduces models and a system for designing 802.11 wireless LANs (WLANs) using flexible channelization — the choice of an appropriate channel width and center frequency for each transmission. In contrast to current 802.11 systems that use fixed width channels, the proposed system, FLUID

The physical locations of clients and access points in a wireless LAN may have a large impact on network performance. However, today’s WLAN management tools do not provide information about the location of clients apart from which access point they associate with. In this paper, we describe a

of each approach and conclude that they cannot resolve all security threats on WLANs. Recently, several wireless vendors propose an integrated approach of applying VPN over 802.11i to protect WLANs. However, there is no published research work on this approach. In this paper, we analyze this integrated

an enterprise. We bring out the similarities between these issues and related deployment issues in cellular networking arena, and discuss various proposed solutions in both contexts. Finally, we survey several advanced architectures that further automate the deployment and management of wireless LANs. I.

In recent years, a wide variety of mobile computing devices has emerged, including portables, palmtops, and personal digital assistants. Providing adequate network connectivity for these devices will require a new generation of wireless LAN technology. In this paper we study media access protocols

Reliable transport protocols such as TCP are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. However, networks with wireless and other lossy links also suffer from significant losses due to bit errors and handoffs. TCP responds to all losses

(MEA) technology, that is processing the spatial dimension (not just the time dimension) to improve wireless capacities in certain applications. Specifically, we present some basic information theory results that promise great advantages of using MEAs in wireless LANs and building to building wireless
