Abstract

In a method for bidirectional transmission of data between a data processing device and a router data is transmitted over a plurality of sections. Data is transmitted over a first section between the data processing device and an access point via an air interface in accordance with a predefined first data transmission method. The data is transmitted over a second section between the access point and a central control unit via a cable-based connection in accordance with a predefined second data transmission method. The data is transmitted over a third section between the central control unit and the router in accordance with a predefined third data transmission method. The access point has a first layer for data transmission in accordance with the first data transmission method and layers hierarchically above the first layer for data transmission in accordance with the first data transmission method are disposed in the central control unit.

Claims

a) the data is transmitted over a first section between the data processing device and an access point via an air interface in accordance with a predefined first data transmission method;

b) the data is transmitted over a second section between the access point and a central control unit via a cable-based connection in accordance with a predefined second data transmission method; and

c) the data is transmitted over a third section between the central control unit and the router in accordance with a predefined third data transmission method;

d) with the access point having a first layer for data transmission in accordance with the first data transmission method and layers hierarchically above the first layer for data transmission in accordance with the first data transmission method being disposed in the central control unit.

2. The method of claim 1, wherein the first data transmission method is a method conforming to IEEE 802.11 and the second data transmission method is a method conforming to xDSL.

3. The method of claim 2, wherein the first layer in the access point is an IEEE 802.11 PHY layer, and wherein an IEEE 802.11 MAC layer is disposed in the central control unit.

9. The method of claim 2, wherein the first layer in the access point is an IEEE 802.11 PHY layer, and wherein an IEEE 802.11 MAC layer and higher layers are disposed in the central control unit.

4. A system for bidirectional transmission of data between a subscriber terminal, in particular a data processing device, and a router, in which system the data is transmitted over a plurality of sections, wherein
