摘要： Methods, apparatuses and systems directed to optimizing vector models for use in modeling RF propagation in desired physical environments. In one embodiment, the present invention can operate on pre-existing vector models. In other implementations, the present invention facilitates the conversion of raster images of buildings and other physical locations to vector formats for use in connection with the computational modeling of radio-frequency (RF) propagation. According to certain embodiments, the present invention is implemented within the context of a location diagram editing application that supports a line recognition filter, a snap filter and a merge filter which a user may individually select and configure. As discussed more fully below, the line recognition filter operates on the vector objects to adjust near-vertical lines (as defined by a configurable threshold angle) to vertical, and near-horizontal lines to horizontal. In some configuration modes, the line recognition filter may also delete lines that are oriented at an angle greater than a threshold from the x-axis and y-axis to, for example, clean up vector objects corresponding to text and other elements that are usually analytically irrelevant to modeling RF propagation. The snap filter, in one implementation, operates to extend closely spaced objects that are oriented within a threshold distance from each other. The merge filter operates, in one implementation, to merge closely spaced parallel lines to, for example, adjust the vector file to correctly model a wall with a single vector object. In one implementation, the output resulting from the invention is a vector file that has each wall accorded a given wall type, and is optimized for use in connection with an RF prediction engine.

摘要： A distributed network is provided with mobile user devices, a virtual “Virtual Private Network” (VPN) server, and a plurality of physical VPN servers, wherein the virtual VPN server allows all mobile user devices to be configured with a single VPN server address, namely that of the virtual VPN server. The plurality of physical VPM servers all recognize and intercept network traffic sent to the virtual VPN server address, so that traffic can be distributed throughout the network. Specifically, each real VPN server responds to network traffic sent by a mobile user device to the address of the virtual VPN server and communicates with the mobile user device using the virtual VPN server address in preference to the individually assigned address of the real VPN server.

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 on 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： A wireless node location mechanism that dynamically adapts to changes to a surrounding physical environment that affect the propagation of radio signals. The wireless node location mechanism assesses radio signals from transmitters associated with a wireless node location infrastructure to adjust one or more parameters used to estimate location of a wireless node. In one implementation, path loss exponents are re-computed based on the signals transmitted between infrastructure radio transceivers. These path loss exponents are used, in one implementation, to compute the distance between a wireless node and a given infrastructure radio transceiver and, ultimately, to determine the location of the wireless node based on triangulation. In one implementation, path loss exponents are computed on demand based on the signals observed between infrastructure radios that detect the wireless node whose location is to be estimated.

摘要： In a fixed channel wireless network system with a limited number of channels, assignment of the fixed channels between remote client elements and access elements is made systematically according to a set of criteria accounting for network loading and interference, then channel assignments are dynamically updated according to a priority to maintain optimal network performance with changing conditions of load and interference. The channel utilization problem is address at a system level rather than at a local level by treating the system as a three dimensional color mapping problem. All noise is treated as having a source in virtual access elements with an appropriate performance metric. The performance metric is used to select a channel set that minimize chances of interference and maximize user performance. Specifically, there are several parameter matrices which are managed and updated by a central resource management element, namely signal strength between elements, interference, and load. These matrices are used to find the optimal channel assignments for a predetermined limited set of assignable channels.

摘要： Methods, apparatuses and systems enabling real-time analysis of coverage and other performance attributes of distributed or networked systems, such as wireless computer network environments. In one embodiment, the present invention utilizes information obtained from monitoring wireless communications in a wireless network system from remote client elements to access elements in relation to at least one attribute, such as signal strength and signal-to-noise ratio (SNR). Although the present invention has application to a variety of wireless network architectures, in one embodiment, the present invention is implemented in a wireless Local Area Network (WLAN) system having a hierarchical architecture comprising a central control element associated with at least one access element. The access element encapsulates data packets received from remote client elements including protocol and other information (such as attributes of the detected signal associated with the data packets), and tunnels the encapsulated data packets to the central control element. The central control element maintains and analyzes the information contained in the packets to analyze the coverage of the wireless network environment.

摘要： Methods, apparatuses and systems directed to refreshing signal information in an infrastructure wireless node location mechanism. The wireless node location mechanism selectively terminates connections with wireless clients to refresh signal strength information used to compute an estimated location for the wireless clients. The wireless node location mechanism terminates the connection between a WLAN and a given wireless node, causing in typical WLAN protocol implementations, the mobile station to transmit frames or packets on all available operating channels in a given band. This allows access points and other WLAN elements, operating on different frequency channels, to detect frames transmitted by the mobile station and provide refreshed signal strength information to a wireless node location mechanism.

摘要： Methods, apparatuses and systems directed to a wireless network interface supporting directional antenna diversity. Directional diversity, in one embodiment, makes use of antennas with higher gain and non-overlapping patterns to provide communication over a greater area and select the best antenna to receive signals transmitting wireless frames or packets. Certain embodiments optimize wireless network systems using Orthogonal Frequency Division Multiplexed (OFDM) signals where spatial diversity protection provided by spatially-separated, omni-directional antennas is not required. In other embodiments, use and selection of directional antennas allows for sectorization resulting in performance gains such as extended coverage areas, noise reduction, enhanced efficiency, and increased throughput.
