Abstract
Provided are systems and methods for communicating between mobile devices. Such methods involve establishing a communication session between the mobile devices using a local network, such as a Wi-Fi network. The methods also involve transmitting data streams from one mobile device in the group to all other mobile devices using this local network. The data streams may include audio and/or video data generated by the mobile devices. For example, mobile device users may conduct a teleconference through the local network and/or share media. The mobile devices may be interconnected using a star or ring topology, which may depend on distances between participants and/or alarm features that reflect connection losses between the mobile devices. Each mobile device may be equipped with one or more microphones for collecting audio signals from its user. A mobile device may also include an audio processing system for noise suppression and/or echo cancellation.
