20140334379 | SYSTEM FOR MANAGING MOBILE INTERNET PROTOCOL ADDRESSES IN AN AIRBORNE WIRELESS CELLULAR NETWORK - The Aircraft Mobile IP Address System provides wireless communication services to passengers who are located onboard an aircraft by storing data indicative of the individually identified wireless devices located onboard the aircraft. The System assigns a single IP address to each Point-to-Point Protocol link which connects the aircraft network to the ground-based communication network but also creates an IP subnet onboard the aircraft. The IP subnet utilizes a plurality of IP addresses for each Point-to-Point link thereby to enable each passenger wireless device to be uniquely identified with their own IP address. This is enabled since both Point-to-Point Protocol IPCP endpoints have pre-defined IP address pools and/or topology configured; each Point-to-Point Protocol endpoint can utilize a greater number of IP addresses than one per link. Such an approach does not change IPCP or other EVDO protocols/messaging but does allow this address to be directly visible to the ground-based communication network. | 2014-11-13 |

The processor may be configured to send a request to and receive a response from the communication partner via the communication port using modulated signals, measure a time period between sending and receiving using timings of modulated signals' symbols, and receive a secondary value from the communication partner. The secondary value may be verified to include at least a portion of the request and a portion of the response, and may have been sent with authenticating data to authenticate it. The time period may be compared with a predefined threshold calculated based on a predefined maximum allowed distance to the communication partner. In another aspect, an apparatus may be configured to ensure its proximity to a communication partner. | 2014-11-13 |

20140334470 | Fast Path to Capture Network Data to Disk Storage - A method and system for virtualization of access points are disclosed. According to certain embodiments, after the access point network processor captures the packets and stores the data on the direct memory access (DMA), the access point's OS is designed to call an access point kernel-space driver to directly transfer the data from DMA to the access point's hard disk and thus bypasses the access point's OS File System. | 2014-11-13 |
20140334471 | Cloud Controller Mobility Domain - A method and system for virtualization of access points are disclosed. According to certain embodiments, separate wireless mobility domains can be used to manage access points. | 2014-11-13 |
20140334472 | Network Access Method, Interface Device, and Mobile Network Access Device - A network access method, an interface device, and a mobile network access device are provided. The interface device may specifically include: a first network port, a first processor, and a first universal serial bus (USB) interface, where the first USB interface is connected to the mobile network access device; the first network port is connected to a wired wide area network; and the first processor includes a detection unit and an instruction unit, where the detection unit is configured to detect whether the wired wide area network is available and the instruction unit is configured to send, when the detection unit detects that the wired wide area network is available, first network access instruction information to the mobile network access device by using the first USB interface. | 2014-11-13 |
20140334473 | METHOD AND APPARATUS FOR MITIGATING INTERFERENCE IN A WIRELESS NETWORK THROUGH USE OF TRANSMIT BEAMFORMING - In a method for reducing interference in a first wireless communication network and a second wireless communication network, a first access point (AP) device of the first wireless communication network coordinates with a second AP device of the second wireless communication network with respect to utilizing transmit beamforming at the first AP device and transmit beamforming at the second AP device for the purpose of reducing interference in the first wireless communication network and the second wireless communication network. Based on coordinating with the second AP device, the first AP device uses a beamforming matrix to transmit, via a multiple input, multiple output (MIMO) communication channel, to one or more first stations in the first wireless communication network for mitigating interference between the first wireless communication network and the second wireless communication network. | 2014-11-13 |
20140334474 | ARCHITECTURE FOR SIGNAL AND POWER DISTRIBUTION IN WIRELESS DATA NETWORK - An architecture is provided for coupling wireless local area network (WLAN) signals between an internetworking device and a remotely located access point using a transport network. The access point is coupled to the transport network for communicating with the internetworking device. The access point includes a wireless local area network (WLAN) access point and an access point remote converter. The WLAN access point receives wireless local area network signals from wireless computing equipment and converts such signals to local area network compatible signals. The access point remote converter receives the local area network compatible signals from the WLAN access point and converts the signals to transport modulated format signals suitable for transmission over the transport network. | 2014-11-13 |
20140334475 | Association Update Message and Method for Updating Associations in a Mesh Network - An association update message for mesh networks according to the IEEE 802.11s standard provides the ability to include a plurality of associations in an association update message and thus ensure simultaneous updating of a plurality of associations of representative nodes with respect to the proxy nodes (proxy mesh stations) thereof. A threatened inconsistency in an association update in conventional systems, which provides for only one transmission of an association update message per association update, is thereby eliminated. The proxy information field has an identification field with a plurality of identification fields. The identification fields advantageously allow variable structuring of the proxy information fields, that is, dependent on the information transmitted, which also provides the ability to prevent redundant information in the proxy information fields. | 2014-11-13 |
