    • The RF coverage area of a heterogeneous home networking sys­ tem (100a) installed within a building which is constituted by a number of wired (102d) and/or wireless local area net­ works (102a,b,c,e) connected to a wired 'backbone (106) that comprises a number of wired-to-backbone bridges (109) and wireless- to-wired bridges (112a-e) to the backbone (106) is extended. A method comprises the steps of allocating (SOa) a number of wired and/or wireless transmission channels and bridging (SOb) between home network media elements of dif­ ferent multimedia data types on allocated transmission chan­ nels at a predefined layer of the underlying protocol stack. Using (SI) a common media access control (MAC) layer for the entire home networking system (100a) for accessing (S2) dif­ ferent backbone media (106) thereby allows simple integration (S2’) of different types of home network media elements in­ terconnected by said home networking system (100a). This me­ dia access control (MAC) layer is controlled by a central backbone controller (ųC) and appears to the outside world as one overall controlling instance. In contrast to the state of the art, the invention uses different physical (PHY) layers on the backbone media and the wireless local area networks (102a,b,c,e) for mapping (S4) the PHY-layer representation of an RF signal transmitted via an allocated RF transmission channel of a wireless local area network (102a,b,c,e) con­ nected to the home networking system to an IF signal on a backbone medium of the wired Ethernet LAN (106), combines home network media elements of different multimedia data types on the RF/PHY layer and thus enables an extension of the RF coverage area without 'the need of new frequency re­ sources or loss of bandwidth. Each wireless-to-backbone bridge (112a,b,c,e) thereby comprises a PHY-layer conversion stage (304) for mapping the PHY-layer representation of an RF signal transmitted via an allocated RF transmission channel of a wireless local area network (102a,b,c,e) to a signal on a backbone medium (106). The controlling instance of the backbone (104) and the wired ackbone (106) can be a Powerline communication system which is specially adapted to use the IF spectrum of an RF signal received via an allocated RF transmission. channel of a wire­ less local area network (102a,b,c,e) on the mains.

    • A first wireless ad hoc network with a certain available amount of bandwidth comprises a plurality of wireless terminals communicating via wireless connections with each other. Each wireless connection requires a certain amount of the available amount of bandwidth. A problem occurs, if a wireless terminal wants to set up a new wireless connection requiring bandwidth or requires more bandwidth for an existing wireless connection and the required amount of bandwidth exceeds the left amount of the available amount of bandwidth of the first wireless ad hoc network. In a state of the art wireless ad hoc network the requested bandwidth cannot be provided and a user application may not be possible. According to the invention, however, the required amount of bandwidth can be provided by splitting the first wireless ad hoc network such that a second wireless ad hoc network is spawned which operates in a different communication channel and thus provides additional bandwidth. The second wireless ad hoc network comprises wireless terminals of the first wireless ad hoc network and/or new wireless terminals.
