Abstract: A method for controlling the transmission of data via data connections associated with different applications, by means of a transmission medium in a local network having at least two stations for data transmission. Different priorities and different parameters characterizing a quality of service are associated with the applications. The establishment, by a first station, of a new data connection associated with a first application is limited according to the available free channel capacity of the transmission medium and the use of the transmission medium by existing data connections having associated applications containing a priority corresponding to the first application.

Abstract: The invention relates to a transmitter-receiver pair for improved data transmission in a multi-carrier system and to a corresponding method, according to which a chain coding is used. To this end, a transmitter has a first coding stage, a transmission-demultiplexer stage, a second coding stage, a modulator stage, a transmission multiplexer stage and a multi-carrier modulator, whereby said transmission-demultiplexer stage and the transmission multiplexer stage are controlled by a bit loading device. Similarly, the receiver has a multi-carrier demodulator, a receiver demultiplexer stage, a first decoding stage, a receiver multiplexer stage and a second decoding stage, whereby the receiver multiplexer stage and demultiplexer stage are in turn controlled by the bit loading device.

Abstract: A method and apparatus for operating a short-haul radio transmitting/radio receiving system conforming to a short-haul radio communication standard wherein a maximum number of devices able to communicate is exceeded. The devices exceeding the maximum number of devices communicating with a master device are switched to a park mode and, continually in keeping with a predefined strategy, parked devices are switched to active while active devices are switched to parked.
