Conclusions and Outlook
In this work, performance enhancements of IEEE 802.11a/h wireless LANs have been investigated. Two approaches have been discussed to achieve this goal: the first one is spectrum management including dynamic change of frequency channel, transmit power and physical bit rate, the other one is using a cross-layer scheduler at the access point to maintain the communication inside a radio cell to serve multiple users, by sequential or parallelised transmission of packets.
