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.

Abstract: In a method for operating an RLAN arrangement (1) having a plurality of communication units (10, 20), wherein a step of monitoring the presence or occurrence of signals from external radar sources (100) is performed by at least one of said communication units being not in a transmission state as a monitoring unit, thereby realizing a continuous and uninterrupted monitoring of a presence of signals of external radar sources (100) over the complete operation time of the RLAN arrangement (1).

Abstract: For a connection of a network requiring a certain quality of service (QoS), i.e. a QoS connection, generally a fixed amount of bandwidth is allocated. In prior art networks this fixed amount of bandwidth cannot be used by other connections. Therefore, in case the QoS connection does not require all of the allocated fixed amount of bandwidth, bandwidth may be wasted. The present invention provides a method that enables the use of bandwidth, that is currently not used by a QoS connection. This currently unused bandwidth is temporarily freed, such that other connections may use this freed bandwidth. In case all or parts of the freed bandwidth is needed again by the connection, the bandwidth is re-allocated to the connection immediately.
