International Classification:
H04Q 7/20
US Classification:
455450, 4554521, 455464, 455 412, 455500
Abstract:
A multiple access wireless communications architecture provides selective, simultaneous communications with wireless devices located in different sections of a spatial area around a communications apparatus referred to as “sectors”. This includes communications between wireless devices in a single sector, between wireless devices in different sectors and between wireless devices and a wired network or wireless backhaul network. The wireless communications architecture generally includes two or more wireless antenna arrangements that are each configured to provide communications with wireless devices located in a particular sector. Each wireless antenna arrangement is further configured to determine whether signals are being communicated on a communications channel before transmitting on the communications channel. This may be implemented, for example, using a carrier sense or energy detection mechanism. Wireless devices within a sector may communicate on the same or different communications channels, depending upon the particular multiple access protocol employed.

System For Reducing Bus Overhead For Communication With A Network Interface
View pageUS Patent:
20020009075, Jan 24, 2002
Filed:
Jul 24, 1997
Appl. No.:
08/899435
Inventors:
NESTOR A. FESAS - AUSTIN TX, US
International Classification:
H04L012/56
US Classification:
370/363000
Abstract:
The present invention provides a method and an apparatus for transferring data between a computer system and a network interface card that avoids virtual-to-physical address translations. The computer system allocates blocks of memory during system initialization for storing data in transit between the computer system and the NIC, and the physical addresses of these blocks of memory are stored in a table on the NIC. Consequently, address conversion is performed only once, when the memory is allocated. When a request to transfer data to the NIC is received from the upper layers, the device driver copies the data from the upper layers into the next available memory block. The device driver then formats a command and passes it to the NIC for processing. Data transfer commands are communicated to the NIC through a packet descriptor command (PDC), which is a 32-bit value subdivided into fields that completely describe the data transfer operation. The PDC contains a small ordinal value that indexes a table in the NIC, which includes a set of physical addresses of buffers preallocated by the computer system in the computer system memory. These buffers are used for storing data in transit to the NIC. The PDC also contains the length of the buffer to be copied to or from the NIC. The present invention also allows for multiple packets to be formatted into buffers and then subsequently transferred to the NIC in a single I/O operation.

Managing Wireless Base Stations Using A Distributed Virtual Base Station Manager

20080020801, Jan 24, 2008
Filed:

International Classification:
H04B 1/38
US Classification:
455561
Abstract:
To manage a group of wireless base stations (WBS), a network administrator accesses one of the WBS, which serves as the management point. The management point WBS distributes parameters to each WBS to configure each WBS. Each WBS has logic thereon to that allows the WBSs to discover one another and self-organize into one or more clusters of WBSs. The WBSs cooperate to select one of the WBS as a master of each cluster. Furthermore, the logic on each WBS provides for a failure mechanism such that if the master becomes inoperable, another WBS is promoted to master. These self-organized clusters of WBSs collaborate to provide a variety of services, such as fast handoff of client devices, load balancing, and rogue device detection/mitigation. Based on the foregoing, there is no single point of failure.

International Classification:
H04Q 7/24
US Classification:
370338
Abstract:
According to an approach for mitigating the effects of rogue WAPs in wireless local area networks, a determination is made of one or more clients that are communicating with a rogue WAP. For example, messages may be intercepted and examined to identify messages that are sent by or to rogue WAPs. Information that identifies the one or more clients is then extracted from the messages and stored in a client list. Communications between the one or more clients and the rogue WAP are then disrupted. Embodiments of the invention include, without limitation, disrupting communications using deauthentication and by spoofing Address Resolution Protocol (ARP) responses.

International Classification:
H04Q 7/24
US Classification:
370338
Abstract:
An approach for providing wireless network services using a WAP group includes establishing a WAP group that represents a logical grouping of WAPs. Communications between WAPs in the WAP group and clients are performed using a shared BSSID. One of the WAPs in the WAP group is designated as a master WAP and the other WAPs in the WAP group are designated as slave WAPs. The master WAP assigns WAPs in the WAP group to provide wireless networking services to clients. The assignment is performed based upon the performance of communications channels used to carry communications between the clients and the WAPs in the WAP group and current loads of the WAPs in the WAP group. The assignments may be dynamically changed over time, based upon changes in the performance of the communications channels and/or changes in WAP loading.

International Classification:
G06G 7/48
US Classification:
703 7
Abstract:
A method and system dynamically generates virtualized configurations of sensors and signals used in drilling system equipment. The virtualized configurations may be used for novel operational testing of automation systems on drilling rigs. The methods and systems may be configured to virtualize actual drill floor equipment in order to have enhanced fault coverage of the automation systems. A control network that is a component of the automation systems may implement a testing loop that accommodates virtualized equipment in a manner substantially similar to actual equipment. In this manner, the testing loop may be configured to control elements specific to the equipment under control, and generate testing results for those specific control elements.
