In radio networks having a plurality of access points, for example WiFi, a wireless audio end device like for example a microphone or headphones is connected to an access point, to which it sends its audio data or from which it receives same. Audio transmission should occur as far as possible in interruption-free manner and with low latency. If the audio end device is moved the connection quality in relation to the previous access point can decrease and require scanning or roaming. In that respect first another base station is sought and then the radio connection is redirected there. In order in that case to avoid disruptive signal interruptions portions of the audio signal which can be particularly well predicted are detected or predicted by means of short-term statistical methods, like for example speech pauses. Scanning and roaming are then carried out during the predicted portions, whereby interruptions which are perceptible to a user are avoided.

Apparatus for the configuration of a wireless radio connection and method of configuring a wireless radio connection

A method for receiving audio data streams with mobile devices in different rooms in which sound is emitted via loudspeakers. Each mobile device connects over a local wireless network to a server that controls the sound emitted in the rooms via loudspeakers. Each mobile device detects room information, emitted only in the corresponding room, that indicates the room the respective mobile device is in. The room information is transmitted from each mobile device to the server. The server associates each room information with an output audio data stream that corresponds to the sound emitted via loudspeaker in the respective room in which the mobile device has detected the room information. The server assigns to each of the mobile devices an output audio data stream corresponding to the respective room information, and transmits the output audio data stream over the local network to the mobile device, which receives and replays it.

Method for receiving audio data streams with mobile devices and correspondingly configured mobile device

An improved method for configuring an audio reproduction device for detecting sound and providing different output audio signals in a plurality of rooms where at least two wireless microphones connect via a local network to an audio streaming server. Each of the wireless microphones detects room information indicating the room in which it is located, and transmits it to the server, together with an input audio signal. The server compiles at least two different output audio signals according to the respective room information from the input audio signals, and assigns each to a room. The output audio signals are provided via the local network in the rooms such that each of the output audio signals may be received in all rooms, and may be replayed only in the room to which it has been assigned. Each wireless microphone may be used in each of the rooms.
