He added: "With a variety of Certified Wireless USB silicon and end-user products available, we expect to see other OEMs and ODMs follow suit in the coming months as Wireless USB continues its march to broad adoption." The first certified products are: the Dell Inspiron 1720 notebook; D-Link–wireless USB adapter (DUB-1210) & 4-port wireless USB HUB (DUB-2240); IOGEAR's wireless USB hub & adapter kit; and Lenovo ThinkPad T61/T61p 15.4-inch wide screen notebook. These products include certified silicon from Alereon, Intel Corporation, NEC Electronics Corporation, Realtek Semiconductor and WiQuest. Certified Wireless USB is claimed to be the first high-speed wireless personal interconnect technology combining the speed and security of wired Hi-Speed USB with the ease-of-use-of wireless technology. It is backward compatible with wired USB, allows users to connect up to 127 devices and delivers a bandwidth of up to 480Mbps at three metres and 110Mps at 10 metres. It is based on the WiMedia Alliance Ultra-wideband Common Radio Platform. The Wireless USB Promoter Group, consisting of seven companies - Agere Systems, Hewlett Packard, Intel, Microsoft, NEC, Philips Semiconductors and Samsung - defined the core Certified Wireless USB specification with the support of more than 100 contributor members. The group has now transitioned the specification's management to the USB-IF, the supporting governing body of USB specifications. Wireless USB joins a growing family of personal area networking technologies that includes Bluetooth, Zigbee and Wibree. However all have different performances and different applications. The aim of Wibree, developed by Nokia , is to provide short range wireless communications for small very low power devices such as wrist watches. Zigbee is a relatively low speed technology designed for sensor and monitoring applications and with meshing capabilities enabling devices to be interconnected over a wide area. Wibree was initially a competitor to a planned low power version of bluetooth, but the two sides have agreed to combine their efforts into a single technology.{moscomment}
