The present invention provides a new and unique method and apparatus for detecting in a short-range communication device, such as a WLAN station (STA), the trend in WLAN signal strength based on one or more characteristics, e.g. received signal strength values and current time of their observation, by fitting a generalized linear model to the values. Based on the detected trend, three things can be inferred: 1) WLAN radio coverage available for STA is strengthening, 2) WLAN radio coverage available for STA is stationary, or 3) WLAN radio coverage available for STA is weakening.
