WiQuest Communications recently announced the availability of its WQST110 and WQST101 chipset, claimed to be the industry's first commercially-available, high-performance silicon delivering wireless communication speeds up to 1 Gbps. Based on the WiMedia UWB physical layer (PHY) and media access controller (MAC) specifications, the WQST110 builds upon and extends the performance capabilities of UWB communications systems to a new level, providing a solid foundation for high-speed wireless cable-replacement applications. The companion WQST101 RF transceiver chip combines with the WQST110 to provide the first complete UWB solution for manufacturers of PC and peripheral systems, consumer electronics, home entertainment, portable gaming, multimedia platforms, mobile devices and more. In addition to the new chipset, WiQuest is also announcing the immediate availability of the WQST100EVK, a complete UWB system evaluation kit which contains silicon and software for customer assessment, testing and product development.



The WQST110 is a wireless CMOS IC combining baseband PHY, MAC engine, high-speed security processor, quality of service (QoS) manager and a rich variety of host interfaces, all in one highly-integrated design. Designed to optimize the UWB system bill of materials, the WQST110 contains a complete high-speed USB subsystem including controller and transceiver, removing any additional USB component cost. The chip's versatile USB subsystem supports both host-side and device-side connectivity through firmware-controlled configuration management, allowing this chipset to enable a broad range of devices and applications. Coupled with WiQuest software drivers, the WQST110 is suitable for all Certified Wireless USB applications. Unlike other UWB implementations, the WQST110 eliminates the need for expensive external memory, and the chip's innovative architecture provides excellent power control and management for longer battery life in mobile devices. This IC also implements a tightly-coupled interface with the WQST101 RF transceiver to ensure best-in-class wireless chipset performance, robustness and reliability.



To assist customers with quick design support and system integration, WiQuest offers complete reference designs for Certified Wireless USB applications, including daughtercard modules, external plug-in 'dongles' and USB embedded device/hub implementations. These reference designs include schematics, layout details, bill of materials and design documentation. Software support packages including firmware and device drivers are available in conjunction with these hardware reference designs, which support host wired adapter (HWA), device wired adapter (DWA), dual role device (DRD), as well as Certified Wireless USB device implementations.
