Filed:

Oct 24, 2013

Appl. No.:

14/061931

Inventors:

Bryan Goldberg - Vienna VA, US
John Kim - Centreville VA, US
Praveen Srivastava - Ashburn VA, US
Ahmed Bencheikh - Fairfax Station VA, US

International Classification:

H04W 16/18

US Classification:

455446

Abstract:

A graphical user interface displays a proposed site plan of one or more new base stations with respect to existing network infrastructure in a geographical region. While in the field, an installation specialist can perform an in-person survey of the geographical region to determine whether a proposed location is suitable for installation of a wireless base station. The installation specialist may identify an obstacle that would inhibit a newly proposed wireless base station from providing desired coverage if installed at the proposed location. Via input to the graphical user interface, the installation specialist proposes an alternative location in which to install the new base station. A processor performs a validity check and provides feedback indicating whether installation of the new base station at the alternative location is acceptable. The graphical user interface also can support collection of site survey data to monitor progress of the installation.

Inventors:

Praveen Srivastava - Ashburn VA, US

International Classification:

H04W 88/08

US Classification:

370328

Abstract:

A wireless mesh network employs an integrated interface between a plurality of access points for mitigating throughput degradation of multiple consecutive “daisy chain,” or mesh, links. The mesh network employs a plurality of access points, each linked back to a root access point by a series of “hops” through other access points. The wireless mesh network, therefore, employs a plurality of access points operable for wireless links to subscriber, or user, devices, including cellular phones, smart phones, tablet and laptop computing devices, or any suitable portable or handheld computing device. Access points establish an integrated interface with an adjacent access point for direct coupling of the access points for message traffic. The resulting integrated access point establishes a wireless link to a root access point connected to a backhaul network from which media services emanate.

International Classification:

H04W 36/08

US Classification:

370332

Abstract:

Techniques disclosed herein include systems and methods for providing active mobility of Wi-Fi enabled devices within a given wireless local area network (WLAN). In general, techniques include dynamically commanding Wi-Fi enabled devices to disconnect from a corresponding access point in response to meeting predetermined conditions. A forced disconnect can be based on various criteria such as low-power or lost packet thresholds triggering the forced disconnect. Such techniques cause a Wi-Fi enabled device to disconnect from one access point and connect to another access point before a connection quality deteriorates to a point that causes noticeable interruptions in connectivity or a generally poor experience, thereby enabling a smooth transition among access points.

Praveen C. Srivastava - Ashburn VA, US

International Classification:

H04W 36/00

Abstract:

A first wireless access point receives communications from multiple candidate wireless access points in a monitored region in which the first wireless access point resides. The communications indicate presence of the multiple candidate wireless access points in the monitored region. A processing resource associated with the first wireless access point processes the communications to identify which of the multiple candidate wireless access points are trusted wireless access points belonging to a network in which the first wireless access point resides. To facilitate a wireless link handoff from the given wireless access point to one of the trusted wireless access points, the given wireless access point provides notification of identities of the trusted wireless access points to a communication device in communication with the given wireless access point. The communication device selects one of the trusted wireless access points in which to handoff the respective wireless communication link.

Abstract:

According to one configuration, an access point control resource receives channel allocation information indicating a change to allocation of channels in a wireless band currently used by multiple wireless access points to communicate with multiple communication devices in a network. The access point control resource uses the channel allocation information to identify a particular wireless channel (such as a de-allocated wireless channel) to be terminated from use by the multiple wireless access points. In accordance with the channel allocation information, when vacating use of the de-allocated channel, the access point control resource controls an order of terminating use of the particular wireless channel by the multiple wireless access points.

Rajesh Gangadhar - Ashburn VA, US

International Classification:

H04W 8/22

Abstract:

Sensor based information from a base station is received by a configuration management device and is used to determine orientation, altitude and/or location. In some embodiments, the configuration management device compares measurement based information to corresponding expected values in a deployment plan to determine whether or not the base station has been correctly deployed. In some embodiments, the configuration management device uses received sensor based information from a base station to control re-configuration of the base station, e.g., re-orient an antenna or change an antenna pattern.
