With recent advances in wireless technologies, wireless LANs are becoming increasingly widespread as an alternative to fixed access technologies. The IEEE 802.11 standard has gained the most popularity among the different standards and is currently being deployed both within enterprises as well as being used for public access. One of the weaknesses of the basic medium access in the 802.11 standard is its relatively poor support for real-time traffic. In order to provide this support, the MAC layer implements a Point Coordination Function (PCF). In order to reduce the waste and increase the channel utilization this paper presents a modified version of the standard PCF.
