Abstract: A scanning module within a non-AP station receives first scan parameter values for performing a first type of scan to obtain a first type of information, and receives second scan parameter values for performing a second type of scan to obtain a second type of information. From the first and second parameter values the scanning module determines combined scan parameter values that satisfy scan requirements for both types of scans.

The 20/40 parameters and locally-generated background scan parameters are used to determine parameters for performing combined background and 20/40 scans. Reducing the number of scans using combined scans has advantages including increasing data throughput, freeing processing resources, and reducing power consumption.

Abstract: The invention relates to a method for automatically finding an AM radio program, by which an AM radio receiver is tuned through in discrete steps, such that, for each set AM frequency, the reception quality at the currently set AM frequency is determined, the field strength of the neighboring frequencies is measured. If a significant field strength is detected at the neighboring frequencies, these are taken into account in determining the overall reception quality, in that the reception quality is reduced by a noise value, and subsequently the overall reception quality is compared with an upper quality limit. If the upper quality limit is exceeded, the program search is interrupted, and the AM radio program with this high overall reception quality is played. This method succeeds in reducing the number of misjudgments of AM radio programs with actually poor quality, and thus improves the reproduction quality of an AM radio receiver.
