Techniques are described herein that are capable of establishing multiple infrastructure connections to multiple access points via a single wireless network interface controller (WNIC). Capability information is analyzed to determine combination(s) of identified frequency bands over which the WNIC is capable of communicating simultaneously. Availability information is analyzed to determine signal qualities associated with respective available frequency bands. A primary infrastructure connection is established to a first access point via the WNIC based at least in part on a first frequency band associated with the first access point being included among the identified frequency bands and being associated with a relatively high signal quality. A secondary infrastructure connection is established to a second access point via the WNIC based at least in part on a second frequency band associated with the second access point being included among the identified frequency bands in a combination that includes the first frequency band.

Establishing multiple infrastructure connections to multiple access points via a single wireless network interface controller

The present disclosure discloses automated discovery of and seamless connection to wireless receivers for mirroring, extending, and/or projecting images, audio, and/or video from a computing device to the wireless receivers. A smart discovery program discovers a specific wireless receiver that matches a location for a meeting and provides the user with an option to wirelessly connect to the matching receiver during the meeting. The smart discovery program may also use a current location of the computing device to provide a user with a list relevant wireless receivers. Relevant receivers may include those receivers that are both available and located near the computing device. When a computing device connects to a wireless receiver, it may store the receiver ID for the connected receiver in a local receiver log so that the computing device may use this information to connect to the same receiver at a later time.

Smart discovery of wireless receivers

Methods and apparatus are disclosed for device discovery, pairing, and transmission of audio and video media, using two or more communication paths between a media sender/source node and a media receiver/sink node. In one example of the disclosed technology, a method performed with a sink node adapted to receive data via a peer-to-peer communication and a different, second communication path, includes selecting at least a portion of a second communication path to the sink node, determining whether the second communication path is secure, and, if the second communication path is determined to be secure, then accepting connections via the second communication path.

Discovering and protecting data streams in multi-path communication environments

The disclosure herein describes receiving wireless signal strength data and detecting movement of a computing device relative to wireless access points based thereon. The computing device receives a signal strength data stream based on a wireless signal from a wireless access point. A signal strength range is determined based on the signal strength data stream during a learning time period while the computing device is within a defined area. The signal strength range indicates that the computing device is within the defined area associated with the wireless access point. During a detection time period, signal strength values outside of the signal strength range are detected and, based on the detected values, a notification is provided that indicates the computing device has moved outside the defined area. The described movement detection method provides rapid detection of movements of a computing device using already-obtained data that does not rely on interaction with other devices.

Detecting movement of a computing device based on wireless access point signal strength data and adaptive thresholds

Methods and apparatus are disclosed for device discovery, pairing, and transmission of audio and video media, using preference data shared between a media sender/source node and a media receiver/sink node. In some examples of the disclosed technology, a sink node sends, via a peer-to-peer wireless communication path, a discovery message to a source node comprising a preference indication including an indication of a first one of two communication paths to use for the establishing a connection. The sink node receives a request to establish a connection between the sink node and the source node based on the indicated preference. Based on the received request, the sink node establishes a connection between the sink node and the source node. A selected communication path (e.g., peer-to-peer wireless or wireless infrastructure) can be indicated as preferred, along with additional parameters for the media connection.

Dynamic identification of network connection preferences

The disclosure generally relates to identifying a Bluetooth Low Energy (BTLE) enabled Wi-Fi network receiver and automatically connecting to the BTLE-enabled network receiver via a Wi-Fi signal without using a Wi-Fi scanning operation. In some aspects, an initial connection may be established between the network receiver and a BTLE-enabled device during which the Wi-Fi scanning operation of the device is disabled. Thereafter, the device may automatically detect the BTLE-enabled network receiver via BTLE signal and automatically connect to the network receiving using a Wi-Fi signal without using the Wi-Fi scanning operation. In this way, the battery life of the device may be conserved by disabling the Wi-Fi scanning operation. Although the electronic device may be within the Wi-Fi range of the network receiver, the device may not search for or connect to the network receiver if it is outside of the BTLE range of the network receiver.

Method for connecting a network receiver with one or more devices while minimizing power usage

In embodiments of wireless radios managed based on proximity, a mobile device, such as a mobile phone, tablet computer, or other portable device can be implemented for multiple, different wireless communications. A mobile device can include a first radio system for a first wireless communications technology, and a second radio system for a second wireless communications technology. A connection manager determines, based on the first wireless communications technology, whether the mobile device is in an area that is proximate an endpoint implemented for the second wireless communications technology. The connection manager can turn-on the second radio system to enable wireless communication with the endpoint when the mobile device is in the area proximate the endpoint. Alternatively, the connection manager can turn-off the second radio system and conserve power that would otherwise be utilized to scan for the endpoint when the mobile device is not in the area proximate the endpoint.

Wireless radios managed based on proximity

The described method and system enables a client at a branch office to retrieve data from a local hosted cache instead of an application server over a WAN to improve latency and reduce overall WAN traffic. A server at the data center may be adapted to provide either a list of hashes or the requested data based on whether a hosted cache system is enabled. A hosted cache at the client side may provide the data to the client based on the hashes. The hashes may be generated to provide a fingerprint of the data which may be used to index the data in an efficient manner.

Method and system of using a local hosted cache and cryptographic hash functions to reduce network traffic

This document describes management capabilities for a wireless docking experience. A wireless dock is configured to connect to multiple peripheral devices, such as a monitor, a keyboard, and a mouse. Mobile devices can connect to the wireless dock, via a short-range wireless connection, to utilize the multiple peripheral devices. When deployed with other wireless docks, the wireless dock can be configured to provide management information with a broadcast signal that is usable by the mobile devices to manage the wireless connection to, and experience with, the wireless dock. The management information can include one or more of a do-not-automatically-connect indicator, an in-use indicator, an Internet-available indicator, or a group identifier.

Storage and communication de-duplication are described. In one or more implementations, a system comprises one or more modules that are implemented at least partially in hardware, the one or more modules configured to utilize one or more algorithms to calculate hashes of chunks of data, the hashes used to replace the chunks in the data for storage locally in the system as well as to communicate the hashes in response to a request received via a network for the data to avoid communicating at least one of the chunks of the data via the network.

Storage and communication de-duplication

To improve upon existing Winsock implementations, the claimed system and method adapts an existing Winsock system to use out-of-process NSP services. The claimed method and system provides asynchronous Winsock Next calls to provide client application processing flexibility. Further, the claimed method and system provides additional structures for passing additional NSP specific information for a result set to enable further client functionality. One embodiment of the claimed system provides additional client Winsock API functions to aggregate and manage asynchronous calls to multiple NSPs and/or multiple namespaces.

Winsock APIs

A system, apparatus, method, and computer-readable medium are provided for resolving a name to a network endpoint. According to one method, naming providers are registered with a computer system that are operative to resolve names to network endpoints for one or more domains. A provider can claim to be a primary provider or a secondary provider for a domain. A provider can also register as a wildcard provider. Once the providers have been registered, requests may be received to resolve an e-mail address into a network address of the corresponding computer system. In response to such a request, one or more of the registered providers are identified as being able to resolve names in the domain to network addresses. Requests are transmitted to the identified providers requesting that they resolve the e-mail address to a corresponding network address. The manner in which the requests are made depends upon whether authoritative results are required. Once the results of the name resolution have been returned, the results are utilized to establish a network connection to and communicate with the computer system identified by the returned network address.
