FIELD: radio engineering, communication.
SUBSTANCE: Internet service providers are searching for ways to get a better understanding of the end-user's wireless environment including link quality and performance. The proposed method calculates a performance value based on measured round trip times which are sent at different modulation rates. Based the change of performance depending on the modulation rate, conclusions about the possible source of performance problems can be drawn, in particular it can be distinguished between [Bluetooth] (C and E) and distance between station and access point (B) being too large.
EFFECT: high accuracy.
