摘要： The present invention relates to an RF antenna structure that includes a planar structure and a loading plate, such that the planar structure is mounted between a ground plane and the loading plate to form an RF antenna. The loading plate may be about parallel to the ground plane and the planar structure may be about perpendicular to the loading plate and the ground plane. The loading plate may allow the height of the RF antenna structure above the ground plane to be relatively small. For example, the height may be significantly less than one-quarter of a wavelength of RF signals of interest. The planar structure may include two conductive matching elements to help increase the bandwidth of the RF antenna structure.

摘要： Secure access to inventory data concerning a supplier's product located at a seller's premises is provided by tagging units of product with a supplier identifier and a product identifier. The identifiers may be embedded in RFID tags or EPC labels. A secure VPN tunnel is established between a supplier and a seller. The VPN tunnel is associated with a particular supplier identifier such that only inventory data associated with the supplier identifier that matches the supplier is transmitted on the VPN tunnel, and inventory data associated with supplier identifiers that do not match the supplier are filtered out. Hence, the seller can provide the supplier with access to inventory data without exposing sensitive information related to the seller and other suppliers.

摘要： System and method for seamless roaming over scalable wide area Wireless LAN networks (WAWLAN) with clientless mobile subscribers. A preferred embodiment comprises a wireless gateway (WG) coupled to one or more access points in a wireless network to form a wireless cluster (WC), a network access gateway (NAG) coupled to a wired network, and a switch coupled to the WG and the NAG. Each wireless cluster is a Wireless LAN Network (WLAN) with homogenous or heterogeneous network architecture. The WG detects mobile nodes in a wireless cluster and tracks mobile node location in the wireless cluster. The NAG is an anchor point for mobile nodes in the WAWLAN and maintains a fixed source of information about each mobile node regardless of their mobility. The switch provides connectivity between the NAG and the WG. Seamless roaming across Wireless LAN network boundary by mobile subscribers without requiring special mobility enabling client software.

摘要： A commuter groups service (CGS) allows commuters to join commuter groups so that they are able to socialize while commuting. Through the commuter groups, the users may share commuting routes, traffic updates, road conditions, and other information. Group members may arrange car pools, short term riding arrangements, and may anonymously or directly contact each other. The CGS may collect group member position information, e.g. GPS information, to enable the CGS to calculate traffic conditions and to select location specific information for group members. The system may include an on-line service accessible through a computer or wireless networking device. The user may log into the CGS, create or modify a user profile, and join groups of their choosing. Groups may be associated with specific events or with getting to/from work. Commuter groups may be formed for commuters that use private vehicles and/or public transportation.

摘要： The invention relates to a method of estimating symbols carried by a digital signal that is received by a receiver over a communication channel (5), said symbols being multiplexed or orthogonal frequency sub-carriers. The inventive method comprises the following steps in relation to each symbol carried by the digital signal, consisting in: performing at least two transforms towards the frequency domain (8,9) on a portion of the received signal essentially corresponding to the symbol, said transforms being performed with a determined time lag (10) therebetween: estimating the parameters (r0, r1, . . . , rn, r′0, r′1, . . . , r′n) of the communication channel from pre-determined binary information contained in the digital signal; and estimating the symbol from a combination of the result of each of the transforms performed and the estimated communication channel parameters.

摘要： Described are a network, network device, and method for a method of distributing routing information for a virtual private network (VPN) application through a packet-switched network (PSN) having fully meshed provider edge (PE) routers through Provider Backbone Bridge (PBB) tunnels. Each PE router is configured to support at least one VPN and to run a BGP (Border Gateway Protocol) as an auto-discovery process for finding one or more other PE routers attached to the same VPN. A given VPN is associated with a PBB tunnel. A service instance identifier (I-SID), as defined in IEEE 802.1ah, is assigned to the VPN. Each PE router advertises membership in the VPN by including the I-SID assigned to the VPN in a BGP message issued during the auto-discovery process.

摘要： The present invention provides a centralized home controller that is used to coordinate a plurality of associated packet communication clients. The home controller provides a centralized and unified control and messaging system for the various packet communication clients. The home controller also allows the packet communication clients to establish and control packet sessions among the associated packet communication clients, as well as between any one of the packet communication clients and remote clients. The packet communication clients are provided in consumer electronics devices, and the associated packet sessions support data, voice, audio, or video content. In one embodiment, the home controller acts as a proxy for the various communications between the packet communication clients.
