logical and not physical, which can simultaneously connect a host with a number of peripherals. The host divides the available bandwidth through a time-division multiple access (TDMA) strategy. It maintains the ability of USB to safely manage devices on the fly. Hosts can communicate with devices up to 10 meters away. Uses Wireless USB was used in game controllers, printers, scanners, digital cameras, portable media players, hard disk drives and USB flash drives. It was also suitable for transferring parallel video streams, using USB over ultra-wideband protocols. Development The Wireless USB Promoter Group was formed in February 2004 to define the Wireless USB protocol. The group consisted of Agere Systems (now merged with LSI Corporation), Hewlett-Packard, Intel, Microsoft, NEC Corporation, Philips Semiconductors, and Samsung. In May 2005, the Wireless USB Promoter Group announced version 1.0 of the Wireless USB specification. In June 2006, five companies showed the first multi-vendor interoperability demonstration of Wireless USB. A laptop with an Intel host adapter using an Alereon PHY was used to transfer high definition video from a Philips wireless semiconductor with a Staccato Communications PHY, all using Microsoft Windows XP drivers developed for Wireless USB. In October 2006 the U.S. Federal Communications Commission (FCC) approved a Host Wire Adapter (HWA) and Device Wire Adapter (DWA) wireless USB products from WiQuest Communications for both outdoor and indoor use. The first retail product was shipped by IOGEAR using Alereon, Intel and NEC silicon in mid-2007. Around the same time, Belkin, Dell, Lenovo and D-Link began shipping products that incorporated WiQuest technology. These products included embedded cards in the notebook PCs or adapters for those PCs that do not currently include Wireless USB. In 2008, a new Wireless USB Docking Station from Kensington was made available through Dell. This product was unique as it was the first product on the market to support video and graphics over a USB connection, by using DisplayLink USB graphics technology. Kensington released a Wireless USB universal docking station in August, 2008 for wireless connectivity between a notebook PC and an external monitor, speakers, and existing wired USB peripherals. Imation announced Q4 2008 availability of a new external Wireless HDD. On March 16, 2009, the WiMedia Alliance announced transfer agreements for the WiMedia ultra-wideband (UWB) specifications. WiMedia transferred specifications, to the Bluetooth Special Interest Group (SIG), Wireless USB Promoter Group and the USB Implementers Forum. After the technology transfer the WiMedia
