摘要： A wireless discovery and communication mechanism to facilitate configuration, management and performance tasks associated with wireless network environments. In certain embodiments, access elements transmit and receive neighbor messages on a periodic basis to neighboring access elements. The neighbor messages can include configuration and/or protocol information to allow the access elements or associated devices to discover each other over the air. The present invention can be applied to a variety of wireless network architectures, such as a plurality of distributed, substantially autonomous access points, or to a hierarchical wireless network system comprising central control elements, each supervising and controlling one or more access elements as described more fully below.

摘要： Methods, apparatuses and systems facilitating location or containment of rogue or unauthorized access points on wireless computer network environments. Embodiments of the present invention support one to a plurality of rogue containment methodologies. A first rogue containment type involves identification of the physical connection of the rogue access point to the wired network infrastructure and, thus, allows for disabling of that physical connection to contain the rogue access point. Other rogue containment methods involve wireless techniques for containing the effect of rogue access points. In some embodiments, the present invention provides methods, apparatuses and systems facilitating network location of rogue access points to determine whether one or more rogue containment methodologies should be applied. As discussed below, the rogue location and containment functionality described herein can be applied to a wide variety of wireless network system architectures.

摘要： Methods, apparatuses and systems directed to securing a wireless network environment from eavesdropping and other unauthorized activities. One implementation prevents or disrupts meaningful access to information contained in WLAN RF signals that escape from a given physical space during operation of the wireless network. One implementation utilizes overlay RF signals transmitted on one or more operating channels of the WLAN to overpower or mask the internal RF signals escaping from a defined security line or perimeter. One implementation monitors the RF energy escaping to dynamically adjust the power of the overlay signal as required. Implementations of the invention can secure the outer perimeter of an office within a building, or even the outer perimeter of an entire building.

摘要： Methods, apparatuses and systems enabling a distributed wireless network security system. In one embodiment, the present invention provides a wireless network system where security policies are automatically distributed and uniformly implemented across wireless network access points. Embodiments of the present invention address the situation where a malicious user moves to a different access point within a wireless network environment after failing to properly authenticate and/or associate at a first access point. Embodiments of the present invention enable an integrated, multi-layer network security system, wherein a security mechanism at one layer (e.g., link layer security mechanisms) can set policies based on information gleaned from operation of a security mechanism at another layer (e.g., application layer authentication servers).

摘要： A wireless node location mechanism that employs a differential signal strength metric to reduce the errors caused by variations in wireless node transmit power, errors in signal strength detection, and/or direction-dependent path loss. As opposed to using the absolute signal strength or power of an RF signal transmitted by a wireless node, implementations of the location mechanism compare the differences between signal strength values detected at various pairs of radio receivers to corresponding differences characterized in a model of the RF environment. One implementation searches for the locations in the model between each pair of radio receivers where their signal strength is different by an observed amount.

摘要： In a wireless Local Area Network (WLAN) system, a hierarchical architecture is provided which employs a protocol which divides protocol processing functions between a plurality of substantially identical access elements in which reside time-critical protocol functions, such as acknowledgment and retransmission of packets, and a centralized control element which provides control and management functions related to dynamic configuration of wireless networks, such as processing of network management messages (e.g., authentication and association), load control, channel control, and handoff, processing of physical layer information, and processing of channel characteristics, propagation, interference or noise, for the plurality of access elements in the WLAN without loss of information about the wireless characteristics of the access elements. This hierarchical protocol processing architecture allows the data flow to be centralized for better performance and provides useful access to all the protocol information from the WLAN.

摘要： Methods, apparatuses, and systems directed to a wireless node location mechanism that uses a signal strength weighting metric to improve the accuracy of estimating the location of a wireless node based on signals detected among a plurality of radio transceivers. In certain implementations, the wireless node location mechanism further incorporates a differential signal strength metric to reduce the errors caused by variations in wireless node transmit power, errors in signal strength detection, and/or direction-dependent path loss. As opposed to using the absolute signal strength or power of an RF signal transmitted by a wireless node, implementations of the present invention compare the differences between signal strength values detected at various pairs of radio receivers to corresponding differences characterized in a model of the RF environment.
