Abstract

An interface device for a communication network comprises a plurality of first communication nodes and a plurality of second communication nodes, wherein the interface device comprises a switching unit and a transmit-/receive aerial. The switching unit is capable of being coupled, so as to be able to communicate, to each of the first communication nodes and to each of the second communication nodes, and is configurable for transmitting a communication message between one of the first communication nodes and a second communication node, which may be unambiguously allocated to said first communication node. The switching unit may be coupled to the transmit-/receive aerial for wireless communication with each of the second communication nodes by way of the transmit-/receive aerial that may be shared for communicating with each of the second communication nodes.

Claims

a switching unit;

a transmit-/receive aerial;

wherein the switching unit is capable of coupling to each of the first communication nodes and to each of the second communication nodes, and is configured for transmitting a communication message between one of the first communication nodes and a second communication node, which second communication node is allocated to the first communication node;

wherein the switching unit is coupled to the transmit-/receive aerial for wireless communication with each of the second communication nodes by way of the transmit-/receive aerial that is shared for communicating with each of the second communication nodes.

2. The interface device of claim 1, wherein the switching unit is equipped for wire-bound communication with each of the first communication nodes.

3. The interface device of claim 1, wherein the switching unit comprises:

a plurality of transmit connections; and

a plurality of receive connections;

wherein in each case one of the transmit connections and in each case one of the receive connections are capable of coupling to one of the first communication nodes;

wherein each of the transmit connectors is equipped for transmitting a communication message to be sent by one of the first communication nodes; and

wherein each of the receive connections is equipped for transmitting a communication message to be sent to one of the first communication nodes.

4. The interface device of claim 3, wherein the switching unit comprises:

a first signal processing unit,

wherein the first signal processing unit is coupled to the plurality of transmit connections; and

wherein the first signal processing unit is equipped for processing signals to be sent by the transmit-/receive aerial, and the signals are capable of being conveyed to the first signal processing unit by at least one of the transmit connections.

5. The interface device of claim 3, wherein the switching unit comprises:

a second signal processing unit,

wherein the second signal processing unit is coupled to the plurality of receive connections; and

wherein the second signal processing unit is equipped for processing signals received by the transmit-/receive aerial, which signals are conveyable to at least one receive connection by the second signal processing unit.

6. The interface device of claim 1, wherein the transmit-/receive aerial is divided into a transmit aerial for wireless transmission of signals to the second communication nodes, and into a receive aerial, provided separately from the transmit aerial, for the wireless receiving of signals from the second communication nodes.

7. The interface device of claim 1, further comprising:

a plurality of transmit-/receive aerials, each of which is provided for communication with each of the second communication nodes in a shared arrangement.

8. A communication network, comprising:

an interface device of claim 1;

a plurality of first communication nodes; and

a plurality of second communication nodes;

wherein one of the second communication nodes is allocated to each of the first communication nodes such that allocation of the second communication nodes is unambiguous;

wherein the switching unit is coupled, so as to be able to communicate, to each of the first communication nodes and to each of the second communication nodes, and is set up for transmitting a communication message between one of the first communication nodes and a second communication node, which is unambiguously allocated to said first communication node by way of the transmit-/receive aerial that is shared for communicating with each of the second communication nodes.

9. The communication network of claim 8, further comprising:
