    Abstract: The present invention relates to the connection of subnets which operate on different frequency channels and are connected by wireless forwarder stations. According to the present invention, a forwarding station periodically switches to the other frequency channel to remain there for a pre-defined presence duration, whereby jitters of the presence time caused by overlapping packet transmissions are compensated. According to the present invention, a presence and absence time of the forwarder station in the respective subnet is indicated by using signals relating to a power saving mechanism.

    Abstract: The local network has a bridge terminal (57-60) that is connected to the sub-networks (53-56) alternately for the exchange of data. The bridge terminal has a temporary storage medium for the temporary storage of received data for a non-connected sub-network. The bridge terminal transmits temporarily stored data for a sub-network in the order of receipt once connected into that sub-network. An Independent claim is also included for bridge terminal for a local network.

    Abstract: In an Access Point controlled wireless network, wherein one channel communication is ruled by an identifier associated with the Access Point, a method for direct communication between a first station and a second station, comprises the steps of: generating a second identifier by said first station, different from the identifier associated with the Access Point, and optionally choosing a different channel; sending, by said first station, an invitation message for direct communication carrying said second identifier and optionally said second channel to said second station; sending, by said second station, a response message acknowledging the invitation message; setting up direct communication between said first station and said second station using said second identifier and optionally said second channel.

    Abstract: Receiver for receiving a data stream via a data bus, which receiver samples the bits of the data stream in an over-sampling process, in which n bit strobe offsets are used and n data sets with i bits are sampled, - applies a decision criterion for identifying those data sets with correct bit values, selects one of the identified data sets with correct bit values and uses the bit strobe offset, which was used for receiving the selected data streams, for receiving the data stream.
