A network array () comprises a first network () having a plurality of first nodes (), comprises a second network () having a plurality of second nodes (), and comprises a forwarder node (). The forwarder node () constitutes one of the first nodes () and constitutes one of the second nodes () to form a communication interface between the first network () and the second network (). The forwarder node () has an implemented data transmission scheduling management function capable of distinguishing between data to be transmitted between the first network () and the second network () and data to be transmitted within the first network () or within the second network (). The forwarder node () is adapted to communicate with the first network () using a first operation frequency and is adapted to communicate with the second network () using a second operation frequency which is different from the first operation frequency.

Network array, forwarder device and method of operating a forwarder device

A network array () comprises a first network () having a plurality of first nodes (), comprises a second network () having a plurality of second nodes () and comprises a forwarder node (). The forwarder node () constitutes one of the first nodes () and constitutes one of the second nodes () to form a communication interface between the first network () and the second network () in such a manner that the forwarder node () functions as a slave in the first network () and as a master in the second network (). The forwarder node () is adapted to communicate with the first network () using a first operation frequency and is adapted to communicate with the second network () using a second operation frequency which is different from the first operation frequency.

Interconnection of wireless networks using a master/slave node

In a wireless mesh network, an algorithm is used by mesh points in the network to predict the success of and interference created by a new transmission opportunity. In particular, it is provided a method for mesh points, in a mesh network, to determine whether to transmit to another mesh point simultaneously while another transmission is taking place on the same communication link. A mesh point should not transmit to another mesh point if the mesh point's transmission interference disturbs a simultaneous transmission from another mesh point. Furthermore, a transmitting mesh point should not transmit to a receiving mesh point if the transmission will be disturbed at the receiving mesh point from interference from a simultaneous transmission from another mesh point.

Distributed learning method for wireless mesh networks

A fast method for allocating those channels or subcarriers of a multicarrier network to an ahead lying transmission is to let a transmitting terminal and a receiving terminal which intend to access the medium determine the status of the channels or subcarriers that are within their reception range and send a signal indicating the determined status to the corresponding terminal which will select those channels or subcarriers for the eventual transmission which fit best. Other terminals within the transmission range of the transmitting or the receiving terminal respect the reservation and wait for the current transmission to find out which channels or subcarriers are actually used.

Method for reservation of a medium in a radio communication network for data transmission between stations (A-E) of the network comprising at least one station (A, B, E) operating according to a first protocol (DRP) and a second station (C, D) operating according to a second protocol (802.11), the method comprises the steps of: providing a contention free period () within the first and second protocol; performing the reservation of the medium for the first station (A, B, E) according to the first protocol; and performing the reservation of the medium for the second station (C, D) according to the second protocol, announcing the contention free period for the first and second protocol by use of the same signal (). In particular a beacon signal is used, wherein the beacon includes a signal () which is recognized and accepted by the second stations (C, D). Further information () is added into the beacon frame () for reserving reservation periods () for the first stations (A, B, E).
