A method of reducing power consumption of a first wireless communication device is described. A charge level of a battery associated with the first wireless communication device is monitored. A wireless communication session between the first wireless communication device and a second wireless communication device is maintained. Based at least in part on the charge level of the battery being within a low battery threshold range, a wireless signal strength associated with the wireless communication session is monitored. Based at least in part on the wireless signal strength reaching a power saving threshold that is above a minimum connection threshold for maintaining the wireless communication session, a power saving action associated with a wireless interface that supports the wireless communication session is performed.

System and method for reducing power consumption

Techniques for reducing latency between terminal stations in a wireless local area network. In an aspect, two stations in close proximity may be configured to associate with a common access point, by causing one or more of the stations to disassociate from a current access point and reassociating with the common access point. The identity of the common access point may be independently derived at each terminal station using simple broadcast messaging procedures, without the need for extensive communications or handshaking between the stations. In an alternative aspect, a terminal station may repeat the disassociation and reassociation procedures without knowledge of the other station's BSSID, until a measured latency drops below a threshold.

Reducing latency in wireless networks

A client device may obtain a first measurement corresponding to a serving WLAN access point that uses a first channel. The client device may also obtain a second measurement corresponding to a target WLAN access point that uses a second channel. To facilitate intelligent wireless channel selection, the client device may weight at least one of the first measurement and the second measurement based on channel selection settings to obtain at least one weighted measurement. The client device may determine whether to roam from the serving WLAN access point to the target WLAN access point based on the at least one weighted measurement.

Intelligent wireless channel selection

Techniques are described for providing and accessing network services via a peer-to-peer wireless network connection which is established between a first computing device and a second computing device. The first computing device has an additional network connection that allows it to access network services via external networks (e.g., the internet). The second computing device is only connected to the peer-to-peer wireless network connection and has no Internet access. A primary data channel is established between the first and second computing devices over the peer-to-peer wireless network connection (e.g., for streaming audio and/or video content). A secondary data channel is negotiated between the first computing device and the second computing device. The secondary data channel is used by the second computing device to access the network services via the first computing device which performs relay and/or proxy operations for the second computing device.

A method of controlling wireless communication performance in an electronic device includes accessing data containing material properties relating to a plurality of materials, transmitting a first test signal on a first transmission channel with a first antenna at a first location in the electronic device, receiving the first test signal on the first transmission channel with a second antenna at a second location in the electronic device, determining a housing material of the electronic device based on a measured attenuation of the first test signal received by the second antenna based upon the data containing transmission properties relating to a plurality of materials, and adjusting a transmission power of one of the first antenna and the second antenna based upon the material properties of the housing material.

Systems and methods to adjust transmission power in electronic devices

A computing device is able to communicate wirelessly with other devices using different types of wireless networks, such as infrastructure networks and peer-to-peer networks. Situations can arise in which a computing device is connected to different types of networks at the same time. In such situations a check is made as to whether the computing device can connect to a first of the wireless networks using the same channel as is used by the computing device to connect to a second of the wireless networks. If so, then the computing device connects to the first wireless network using the same channel as is used by the computing device to connect to the second wireless network, resulting in the computing device sharing the same channel for the multiple wireless networks.

Roaming to share a communication channel

Smart channel selection for autonomous initiators of peer-to-peer groups is disclosed. A device acting as an initiator device of a peer-to-peer group may configure the group by selecting a channel for the peer-to-peer group, where the selected channel is also the best channel available for potential group member devices to connect to a network having a coverage area in which the initiator device operates. Group member devices operating, or potentially operating, on the peer-to-peer connection will then select the best channel if they connect to the network, and use the same channel for both the peer-to-peer and network connections. Group member devices will then not be required to operate in a multi-channel mode. In embodiments, the best channel may be selected by the initiator device, for example, by determining that the channel has the highest signal strength or the fastest data rate of channels as measured at the group initiator, or by other suitable criteria.

The present invention extends to methods, systems, and computer program products for domain controller safety-features and cloning. Embodiments include cloning virtual domain controllers. Cloning permits virtual domain controllers to be rapidly deployed by copying/cloning the entire operating system state of an existing virtual domain controller. Other embodiments provide safety features protecting domain controllers running within virtual machines from introducing distributed corruption into a directory services data system. Protection is facilitated by detecting when a hypervisor or Virtual Machine Manager ('VMM') uses features that cause a virtual machine to be rolled back in time outside of an operating system's awareness. In response to detecting a feature that causes rollback, safeties can be implemented to compensate for otherwise divergent state and prevent the introduction of duplicate unique identifiers.

Domain controller safety-features and cloning

The present invention provides for an automated, user friendly way of constructing and using a binding object. A developer is presented with and selects binding elements that will ultimately be used to create a runtime communication channel for transporting a message between a client and service endpoint. After receiving the user input, metadata, a channel factory and listener factory are created. The metadata describes binding elements and provides an abstract representation of a protocol stack that implements communication aspects at runtime. The channel factory is configured to use the collection of metadata at runtime to generate the runtime communication channel. Further, the listener factory is configured to accept the runtime communication channel for de-multiplexing the communication aspects in order to process the message at a service endpoint. The present invention also provides for groupings of binding elements and standardized binding objects organized based on industry need.

System and method for building and using communication binding objects

The present invention extends to methods, systems, and computer program products for reliably and securely transferring queued application messages. Application messages are (e.g.,. binary or text) encoded and then encapsulated in transfer messages, enqueue messages, and dequeue responses such that composable protocol elements used in application messages can be reused in the transfer messages, enqueue messages, and dequeue responses. Transfer message headers are encoded and then encapsulated along with encoded application messages such that composable protocol elements used in transfer headers and application messages can be reused in the store and forward messages. Application messages, transfer messages, enqueue messages, dequeue responses, and store and forward messages can all be configured in accordance with the same messaging protocol, such as, for example, Simple Object Access Protocol. Since encapsulated elements are encoded, the encapsulated elements do not interfere with configuration of wrapping messages.

A web services namespace pertains to an infrastructure for enabling creation of a wide variety of applications. The infrastructure provides a foundation for building message-based applications of various scale and complexity. The infrastructure or framework provides APIs for basic messaging, secure messaging, reliable messaging and transacted messaging. In some embodiments, the associated APIs are factored into a hierarchy of namespaces in a manner that balances utility, usability, extensibility and versionability.
