  • Patent number: 8411649
    Abstract: 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.

  • Patent number: 7564878
    Abstract: A method of operating a wireless network, including detecting at least one signal of an external radio source, by a network device of the wireless network, during normal operation of the wireless network, in which while detecting, the network device does not send data to another network device of the wireless network, and changing a communication channel or frequency band, if the at least one signal overlaps with a currently used communication channel or frequency band.

  • Publication number: 20060112161
    Abstract: A network device for an ad-hoc established device network is described, which comprises a content detection layer for detecting the content type of external traffic received by said network device. According to the content type, the external traffic is routed to a content-specific convergence layer dedicated to handling the respective content type. Said content-specific convergence layers exchange network traffic with other network devices via content-specific connections that are suited to the requirements of the respective content type. On the part of a target network device, the received data stream can be routed to any external protocol. Thus, the device network allows interoperability between different external networking protocols.
