Abstract

A wireless communication link between a communication network and a communication terminal device positioned in a predeterminable region may be established and improve capacity for wireless communication. A line-bound communication link to the communication network may be established via a communication base device arranged in a fixed location, and an optically-based communication link to the communication terminal device may be established via an optical deflection device.

First claim

The invention claimed is:

1. A communication base device for a communication device for providing a wireless communication link between at least one communication terminal device positioned in a predeterminable region and a communication network, wherein the communication base device is configured to be fixedly arranged, wherein the communication base device comprises:
a network communication for connecting the communication base device to the communication network;
a light-based communication unit for providing a wireless light-based communication link to a light deflection unit configured to deflect light from the communication base device to the predeterminable region; wherein the light-based communication unit is configured to focus the emitted light onto the predeterminable region; and wherein the light-based communication unit is configured to emit the light in multiple light frequency ranges different from one another and to focus the light of a respective light frequency range onto an assigned one of multiple subareas of the predeterminable region; and
a converter unit for the communication coupling of the communication unit to the network connection.

2. The communication base device as claimed in claim 1 , wherein the communication unit is configured to emit and/or receive light in a predetermined light frequency range individually assigned to the communication terminal device.

3. The communication base device as claimed in claim 1 , wherein the communication unit comprises an optical emitter element configured to emit the light in an oriented manner to provide the wireless communication link.

4. The communication base device as claimed in claim 1 , wherein the communication unit is configured to orient the optical emitter element and/or an optical receiver element of the communication unit onto the light deflection unit.

5. The communication base device as claimed in claim 1 , wherein the communication unit is configured to provide a respective independent individual communication channel for each of a predetermined plurality of communication terminal devices.

6. The communication base device as claimed in claim 5 , wherein each communication channel comprises a predeterminable light frequency range and/or the communication unit is configured to emit the light into predeterminable subareas of the predeterminable region.

7. The communication base device as claimed in claim 1 , wherein the light deflection unit comprises at least one spectral filter element.

8. A communication device for providing a wireless communication link between at least one communication terminal device positioned in a predeterminable region and a communication network,
at least one fixedly arranged communication base device as claimed in claim 1 , and
at least one light deflection unit for deflecting light between the at least one communication base device and the predeterminable region, wherein the light deflection unit is in a fixed positional relationship to the communication base device.

9. The communication base device as claimed in claim 8 , wherein the light deflection unit comprises an orientation unit, so that the light deflection unit is oriented in such a way that the light is deflected into the predetermined region.

10. The communication base device as claimed in claim 8 , wherein the light deflection unit comprises at least one reflector element.

11. The communication base device as claimed in claim 10 , wherein the at least one reflector element is integrally formed with a delimitation wall of a room, which at least partially comprises the predeterminable region.

12. A method for providing a wireless communication link between at least one communication terminal device positioned in a predeterminable region and a communication network, in which a communication base device is fixedly arranged, comprising:
connecting the communication base device to the communication network;
arranging a light deflection unit deflecting light between the communication base device and the predeterminable region, wherein the light deflection unit is in a fixed positional relationship to the communication base device;
providing a wireless light-based communication link between a light-based communication unit of the communication base device and the light deflection unit;
wherein the light-based communication unit is configured to focus the emitted light onto the predeterminable region; and wherein the light-based communication unit is configured to emit the light in multiple light frequency ranges different from one another and to focus the light of a respective light frequency range onto an assigned one of multiple subareas of the predeterminable region; and
coupling the communication unit to the communication network with respect to communication.

13. A method for establishing a wireless communication link between a communication network and a communication terminal device positioned in a predeterminable region, wherein the method comprises:
establishing a wired communication link to the communication network via a fixedly arranged communication base device; and
establishing a light-based communication link via a light deflection unit to the communication terminal device, wherein the light deflection unit is in a fixed positional relationship to the communication base device and deflects light between the communication base device and the predeterminable region;
focusing the emitted light onto the predeterminable region; and wherein the emitted light is emitted in multiple light frequency ranges different from one another; and
focusing the light of a respective light frequency range onto an assigned one of multiple subareas of the predeterminable region.
