SYSTEM FOR MONITORING, CONTROLLING, ANALYZING PERFORMANCE AND/OR TRACING MALFUNCTIONS IN WLANS

摘要

The invention relates to a system for monitoring, controlling, analyzing performance and/or tracing malfunctions in standard radio networks using the recording of the data exchange of a minimum number of channels available in each radio network, wherein at least the channel utilization and/or the number and/or the duration of channel changes and/or the number of clients and/or the number of packet retransmissions and/or the categorization of the traffic (management, data) is analyzed relative to the data exchange. According to the invention, a mobile, portable unit is provided, having a number of radio-frequency receivers covering all available radio channels or the channels identified by the system as relevant. The unit also comprises at least one adapter which prepares the data or data packets recorded by the RF-receivers and transfers them in the form of traffic data to a mass memory of an integrated computer or processor. The recorded, stored traffic data undergoes a statistical analysis according to predefinable characteristic values and the results of the analysis are filed with a high, freely definable temporal resolution in an intrasystem database, wherein if anomalies are detected, the data communication or the traffic data around the time of the anomaly is retrieved and made available for further analysis. The data is recorded in a lossfree manner on all relevant channels and permanently stored. The system allows customer data (MAC-addresses, names of relevant devices, statistics, logs or messages of other customer-specific systems) to be supplied. The system can contain one or more realtime spectrum analyzers which are controlled by the system. The data obtained, such as frequency spectra, time slices relevant to an event, identified radio systems, etc. are likewise stored and can be transferred to other customer-specific systems.
