Described are techniques and systems for service discovery on a network. A media device on the network generates a signature indicative of a particular set of one or more services available for execution on the media device. The signature may be distributed on the network using beacon transmissions from the media device. A receiving media device compares the signature with previously stored service data which associates signatures with service sets. The stored service data may include a local signature indicative of a local service set. Determinations of a match result in the receiving media device using the previously stored data. Unmatched signatures may result in the receiving media device sending a request for service set data. The received service set data may then be used to provide service availability information. The received service set data and associated signature may be added to the stored service data.

Service discovery using a network

Described herein are systems and methods for reducing power consumption in a device while maintaining a wireless local area network connection. An interface processor of a wireless interface is configured to maintain a network connection while an application processor is in a low power mode. The interface processor may awaken the application processor to a high power mode upon receipt of a wakeup signal, loss of network connection, detection of a network suitable for connection, or other pre-determined event.

Power efficient wireless connectivity

Described herein are systems and methods for secure configuration provisioning of network credentials to configure a device to join one or more networks. One implementation provides for distribution of network credentials to associated devices without user intervention while maintaining security and avoiding distribution of the network credentials to external devices, such as a third-party server. Devices may be associated by purchase from a common merchant, registration to a common account, and so forth.

Secure device configuration

A network device may include first and second processors and a wireless transceiver under control of the second processor. The network device may further maintain one or more signatures and a wake-up module executable by the second processor. The wake up module may receive a multicast wireless communication while the first processor is in a low-power sleep mode. The wake up module may determine whether a data portion of the multicast wireless communication includes a signature. If the data portion of the wireless communication includes the signature, the wake up module may cause the first processor to leave the low-power sleep mode and process the multicast wireless communication.

Wake on one-to-many communication

A user device establishes a wireless connection with a wireless local area network using a first radio. The user device then deactivates a second radio of the user device based on establishing of the wireless connection with the wireless local area network. Subsequently, the user device determines whether to activate the second radio based on at least one criterion associated with the wireless connection.
