Abstract: A method of determining a physical location of a device connected to a data network infrastructure including a plurality of connection points at different physical locations, the method including establishing a connection with the data network infrastructure via a cable-based transmission medium, wherein a communication signal passes via the cable-based transmission medium including at least one of the plurality of connection points. A connection point identifier is determined based, at least in part, upon the at least one of the plurality of connection points. A signal characteristic of the communication signal passing via the cable-based transmission medium between the device and the data network infrastructure through the at least one of the plurality of connection points is measured.

Abstract: A system that associates physical locations with network-linked devices in a network to which such devices are connected. This system employs a variety of techniques for establishing device location. The system configuration can vary and can include any type of data network, including LANs, MANs, Wide Area Networks (WANs), Personal Area Networks (PANs), and Home Networks. The system provides location information for particular devices to the network devices and management, and may be used in any of a variety of ways to improve configuration accuracy, control, and security. The location information may also be used to control or secure a device itself.

Abstract: An approach determining a physical location of a device connected to a data network infrastructure that includes multiple connection points at different physical locations makes use of measured signal characteristics. Operational signal characteristics from a device communicating with the data network infrastructure through one of the connection points are measured and a physical location of the device is determined from the measured characteristics. Stored associations of signal characteristics with connection points are accessed in determining the physical location. The device can connect to the connection point via a cable-based transmission medium.

Abstract: A system and method for enhancing Wireless Local Area Network (WLAN) security. The system and method include the generation of a pair of WEP-based encryption keys by a network access point. The key pair is transmitted to one or more clients associated with the access point after the client has been authenticated for access to the network. Each key is preferably randomly generated and the pair is further changed periodically. The timing of the changing of the keys is dependent upon the existing crypto analysis attack capabilities. Individual clients may have unique key pairs or a plurality of clients associated with an access point may share the key pair.
