Podstawowym parametrem sieci WLAN jest przepustowość transmisji. Zdefiniowane w standardzie przepustowości maksymalne teoretyczne są w warunkach rzeczywistych ograniczane z jednej strony jakością kanału transmisyjnego, a z drugiej sposobem działania samego standardu. W przypadku standardu IEEE 802.11 zastosowana metoda komunikacji DCF wprowadza obowiązkowe przerwy w nadawaniu – interwały czasowe IFS, które powodują zmniejszenie przepustowości osiąganej w jednostce czasu. W artykule omówiono różne ulepszenia metody DCF, zaproponowane w wyniku prac naukowo-badawczych. Porównano je pod względem przydatności w rzeczywistych zastosowaniach.

The basic parameter of the WLAN is transmission output. The defined in the standard of output capacity maximum theoretical values are in the real conditions limited, on the one hand, by the transmission channel quality and, on the other hand, by the way in which the very standard acts. In the case of standard IEEE 802.11, the applied method of communication DCF (distributed coordination function) introduces the obligatory pauses in broadcasting – temporal intervals IFS which cause a reduction of the output capacity achieved in a time unit. In their article, the authors discussed various improvements of the DCF method proposed in result of research works. They are compared in terms of their usefulness in the real applications.
