The coexistence of IEEE 802.16 (WiMAX) and IEEE 802.11 (WiFi) in shared radio spectrum is an acute problem. In license-exempt frequency bands, the frame-based medium access of 802.16 requires rigorous protection against interference from wireless local area networks in order to operate properly when sharing spectrum. We focus here on the unlicensed U-NII(More)
In 2003, interests in the Institute of Electronics and Electrical Engineering (IEEE) 802.11 Working Group (WG) led to the formation of Task Group (TG) "S". 802.11s develops a Wireless Mesh Network (WMN) amendment. Unlike existing Mesh products, 802.11s forms a transparent 802 broadcast domain that supports any higher layer protocols. Therefore, 802.11s(More)
Description: Throughout the next decade, 802 wireless systems will become an integral part of fourth generation (4G) cellular communication systems, where the convergence of wireless and cellular networks will materialize through support of interworking and seamless roaming across dissimilar wireless and cellular radio access technologies. IEEE 802 Wireless(More)
Distributed quality of service support in wireless networks that are sharing unlicensed frequency bands is an increasingly significant research problem. The spectral coexistence of dissimilar radio systems has to be addressed in the near future in concerning the widely deployed IEEE 802.11 wireless local area networks and other future radio systems(More)
In recent years, remarkable market competition and economy of scale has resulted in the price erosion of wireless devices for consumer electronics. Especially for wireless data networks, IEEE project 802 provides the standards for mass markets. With ever-growing usage, the demand for ubiquitous wireless networks increases. However, the achievable data rates(More)
