Abstract: A client device encodes data into an audio signal and communicates the audio data to an additional client device, which decodes the data from the audio signal. The data is partitioned into characters, which are subsequently partitioned into a plurality of sub-characters. Each sub-character is encoded into a frequency, and multiple frequencies that encode sub-characters are combined by the client device to generate an audio signal. Frequencies encoding sub-characters may be above 16 kilohertz, so the sub-characters are transmitted using frequencies that are inaudible to humans. The audio signal is communicated to an additional client device, which decodes frequencies from the audio signal to sub-characters, which are then combined into characters by the additional client device to generate the data.

Abstract: A disclosed method includes preventing a first mobile device from connecting to configured networks having connectivity information stored in a configured networks list stored in memory of the first mobile device, establishing a peer-to-peer connection with a second mobile device, performing a data transfer from the first mobile device to the second mobile device over the peer-to-peer connection while continuing to prevent the first mobile device from connecting to the configured networks, and enabling the first mobile device to connect to the configured networks after completion of the data transfer.

Abstract: Disclosed are methods and systems for devices in peer-to-peer networks to form a new group using information sent by a group owner in a previous group session. In some embodiments, a method of delegating group ownership from a first device to a second device for the formation of a new group includes: determining the second device will be the group owner of the new group during a current group session; broadcasting to devices in the current group session that the second device will be the group owner of the new group; dissolving the current group session; and forming a new group with the second device as group owner.

Abstract: Disclosed are methods and systems for broadcasting and scanning for a service simultaneously. The present disclosure provides a solution for devices utilizing Bluetooth and Wi-Fi.

Abstract: The present disclosure describes methods and a wireless mobile device for selectively granting or denying mobile applications (“apps”) access to a cellular network. In various implementations, a wireless mobile device having both WiFi capability and cellular data capability receives a data packet from an app executing on the wireless mobile device. If the app is not whitelisted and the wireless mobile device is not connected to a WiFi network, the wireless mobile device drops the data packet. If, on the other hand, the app is whitelisted, the wireless mobile device transmits the data packet over the cellular network.
