The demands for high-speed, high-capacity, low-cost indoor wireless communications have been raised rapidly in recent years. While the IEEE 802.11a/b/g/n standards are proposed for the wireless local-area networks (WLANs), the IEEE 802.15.3a standard is now developed to fulfill the needs of wireless personal-area networks (WPANs). The WPANs, mainly serving as cable eliminators in personal multimedia equipments, feature much higher data rates but shorter transmission range than the WLANs, which aim at managing the outgoing data communications over the Internet. Instead of competing with, the WPANs actually complement the WLANs to satisfy the diverse requirements in indoor wireless applications.
