Continuous monitoring of performances is necessary to detect critical situations in the radio interface of digital mobile telephone networks. This paper presents a measurement tool that analyzes Transmission Control-Protocol (TCP) level packet traffic and detects the effects of variations in the radio-channel conditions of a wireless network. The analysis algorithm considers the wavelet coefficients of the aggregated-traffic process at a suitably selected number of time scales. Variations in the energy of wavelet coefficients are detected by a statistical test, from which a score is calculated. This indicator reveals changes in the performances of the monitored network.
