Abstract: A wireless network employs at least a base station (1 to 3) and a plurality of assigned terminals (4 to 14) for exchanging user data and control data. That base station (1 to 3) includes a device (21, 22) for correlating a signaling sequence transmitted by at least one terminal (4 to 14) to indicate the wish to use a contention channel and for detecting the pulse evolved from a received and correlated signaling sequence. After a signaling sequence has been detected, the base station (1 to 3) transmits a provision message over a contention channel to be utilized by the assigned terminals (4 to 14).

Abstract: The network has a central device for controlling connections between at least two terminals using several identifiers (LN). At least the terminals contain at least one compression block for reducing an identifier and the reduced total identifier (Mr) containing at least one reduced identifier (Lq-Nq) is provided for identifying a connection between at least two terminals. An Independent claim is also included for a terminal for a network with a central device for controlling network connections and for a central device for controlling connections between at least two terminals using several identifiers.

Abstract: The wireless network has at least one base station (1-3) and several associated terminals (4-14) exchanging control data. The base station transmits a start time point for at least one signaling sequence of at least one terminal. The base station correlates a received signaling sequence and detect the pulses arising from the received and correlated sequence. A terminal generates a signaling sequence by folding two code sequences.

Abstract: The network has several network clusters, each with at least one wireless network node (5-8) for wireless transfer of packet time slices of defined lengths using a time multiplex method whose variable length has at least one value smaller than the lengt a fixed predefined time slice. A wireless network node combines several packets into a super packet and transmits it via a point-to-point connection to all wireless nodes allowed for the data transfer. A wireless network node, after receiving a super packet, extracts a packet from it if the defined location for the packet lies within the associated network cluster An Independent claim is also included for a wireless network node.

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: The base stations (1-3) transmit the start time point of at least one signaling sequence of the terminals (4-14). The base stations contain a correlator of a received signaling sequence and for detecting of a pulse formed from a received and correlated signaling sequence. After reception of a signaling sequence, the base stations refuses or acknowledges the request of a terminal according to a channel capacity in one channel simultaneously used by several terminals.

Abstract: The network has several terminals and an associated central station for allocating time slices of a subsequent time multiplex frame for wireless transmission of packets after receiving a request for transmission of packets during a previous time multiplex frame. After receiving all requests the central station determines a first subset of all transmit terminals intending to send packets to several receive terminals and a second subset of the remaining transmit terminals, sequences the transmit terminals according to the number of receive terminals they intend to transmit to, divides receive terminals associated with a transmit terminal into a first group containing all receive terminals already used as transmit terminals and a second group with all other receive terminals, sequences the receive terminals in both groups according to the transmit sequence as transmit terminals and first selects the receive terminals in the second group. Independent claims are also included for the following: a central station in a wireless network.
