Abstract: A method of identifies an appropriate wireless communication channel in an audio receiving device, that comprises 1) a wireless receiver receiving an audio signal on a particular transmission channel selected among a predefined number of possible transmission channels, and 2) a microphone for picking up a sound in the environment of the audio receiving device. The method comprises a) selecting a channel as the receiving channel among a predefined number of possible transmission channels; b) analyzing the received signal received and the signal picked up by the microphone; c) determining whether a predefined criterion concerning the degree of similarity of the received signal and the signal picked up by the microphone is fulfilled; d) KEEPING the channel as the receiving channel, if the predefined criterion is fulfilled; and e) CHANGING the receiving channel to another channel if the predefined criterion is NOT fulfilled.

Abstract: The application relates to a stationary communication device comprising a housing and an antenna and a transceiver unit operationally coupled to the antenna, the housing being adapted for assuming a specific orientation relative to the surface of the earth when placed in an operational state. The application further relates to a communication system. The object of the present application is to provide a stationary communication device with an antenna that facilitates wireless communication to a portable communication device. The problem is solved in that the antenna is vertically polarized. An advantage of the disclosure is that a stationary wireless communication device with a small height can be implemented. The invention may e.g. be used for the hearing aids, headsets, ear phones, active ear protection systems, handsfree telephone systems, mobile telephones, and accessories to such devices.

Abstract: The invention relates to a method of pairing a first device with a second device, the first and second devices being adapted for wirelessly communicating with each other, the pairing of devices aiming at ensuring communication only between trusted devices. The invention further relates to a communication device, a system, a computer readable medium and a data processing system. The object of the present invention is to provide a simple and intuitive scheme for pairing two wireless devices.

Abstract: The invention relates to an assistive listening system comprising an audio transmitting device adapted for transmitting an audio signal and/or a control signal to a multitude of receiving listening devices and at least one receiving listening device adapted for receiving said audio signal and said control signal from said audio transmitting device. The invention further relates to a method of operating an assistive listening system and to its use. The object of the present invention is to provide an assistive listening system suitable for servicing a multitude of body worn listening devices in a wireless environment. The problem is solved in that the system is adapted to establish a digital link according to the DECT-standard from the audio transmitting device to the at least one receiving listening device, wherein the system is adapted to provide that said link is uni-directional.
