Later in 2007 Belkin, Dell, Lenovo and D-Link began shipping products that incorporated WiQuest technology. These products included embedded cards in the notebook PCs or Hub/Adapter solutions for those PCs that do not currently include Wireless USB. Host wire adapters, device wire adapters, and dual-role devices The WUSB architecture allows up to 127 devices to connect directly to a host. Because there are no wires or ports, there is no longer a need for hubs. However, to facilitate the migration from wired to wireless, WUSB introduced a new Device Wire Adapter (DWA) class. Sometimes referred to as a "WUSB hub", a DWA allows existing USB 2.0 devices to be used wirelessly with a WUSB host. WUSB host capability can be added to existing PCs through the use of a Host Wire Adapter (HWA). The HWA is a USB 2.0 device that attaches externally to a desktop or laptop's USB port or internally to a laptop's MiniCard interface. WUSB also supports dual-role devices (DRDs), which in addition to being a WUSB device, can function as a host with limited capabilities. For example, a digital camera could act as a device when connected to a computer and as a host when transferring pictures directly to a printer. Relation to ultra-wideband (UWB) A common source of confusion is about the relationship between WUSB, WiMedia, and UWB. The UWB and WUSB technologies are not the same, and the terms WUSB and UWB are not synonymous. UWB is a general term for a new type of radio communication using pulses of energy which spread emitted Radio Frequency energy over 500 MHz+ of spectrum or exceeding 20% fractional bandwidth within the frequency range of 3.1 GHz to 10.6 GHz as defined by the FCC ruling issued for UWB in Feb. 2001. UWB is NOT specific to WiMedia or any other company or group and there are in fact a number of groups and companies developing UWB technology totally unrelated to WiMedia. Some companies use UWB for Ground Penetration RADAR, through wall RADAR and yet another company Pulse-LINK uses it as part of a whole home entertainment network using UWB for transmission over both wired and wireless media. WUSB is a protocol promulgated by the USB-IFUSB Implementers Forum The USB Implementers Forum, USB-IF, is a non-profit organisation to promote and support the Universal Serial Bus.... that uses WiMedia's UWB radio platform. Other protocols that have announced their intention to use WiMedia's UWB radio platform include Bluetooth and the WiMedia Logical Link Control Protocol. WUSB vs. Bluetooth Wireless USB and Bluetooth are two different protocols trying to accomplish two entirely different goals. Wireless USB is a high bandwidth wireless protocol with a smaller range than WiFi (and larger bandwidth, and a much reduced power profile), but with higher transfer rates than Bluetooth (though both share a similar range and may be able to use the same PHY/Transceiver hardware much like combo Bluetooth+WiFi devices). Theoretically, a single 2.4 GHz radio device could be constructed that works with all three protocols seamlessly, with any necessary decoding/encoding performed within software. Bluetooth specification 3.0 is currently ongoing and has the goal to also use UWB. In parallel also WiFi shall be seamlessly integrated. There will be negligible differences in throughput when the 3.0 specification is finished. Bluetooth has advantages compared to Wireless USB when it comes to connection establishment. Wireless USB does not have service level security and service discovery. Bluetooth has long experience with connection establishment so a connection can be established from any device. In Wireless USB connection establishment can only be done from the device side.

UWB Other forms of USB over wireless exist, such as those based on the competing direct sequence UWB technology by (Cable-Free USB). The same is also true for other radio frequency based wire replacement systems which can carry USB. The result is that the name 'Certified Wireless USB' was adopted to allow consumers to identify which products would be adherent to the standard and would support the correct protocol and data rates.
