Method for analysing a wireless link of a Wi-Fi node, respective circuit performing the method, and application
First Claim
1. A method for analyzing a wireless link of a wireless node of a customer premises equipment (CPE) device, comprising:
- performing a first test, during which a data transmission is forced through the wireless link, to obtain a first set of parameters comprising at least a measured data rate with a RSSI value andperforming a second test, which is a monitoring mode during which a data transmission of the wireless link is monitored, to obtain a second set of parameters,wherein if the measured data rate with the RSSI value is an uncertainty zone of a reference data, said reference data comprising two sets of data rates with RSSI values measured at two different times in an interference free environment and for two different conditions of path loss, an observed decrease in the measured data rate is assigned to Physics effects or to a Far End Interference based on the second set of parameters.

Abstract
A method for analyzing a wireless link (3) of a wireless node of a customer premises equipment (CPE) device (1) during operation of the CPE device comprises: performing an active test, during which a data transmission is forced through the wireless link, to obtain a first set of parameters, and performing before or after the active test a passive test, which is a monitoring mode during which a data transmission of the CPE device is monitored, to obtain a second set of parameters. In particular, based on the first set of parameters, it is determined whether and to which extent the wireless link is in an uncertainty zone, and based on the second set of parameters, the decision is made to assign an observed decrease in a measured data rate to physics effects or to interference effects.
