On 16 March 2009, the
Alliance announced it was entering into technology transfer agreements for the
Ultra-wideband (UWB) specifications.
has transferred all current and future specifications, including work on future high speed and power optimized implementations, to the Bluetooth Special Interest Group (SIG), Wireless USB Promoter Group and the USB Implementers Forum. After successful completion of the technology transfer, marketing, and related administrative items, the
Alliance ceased operations.
Alliance developed reference technical specifications including:

transferred specifications, to the Bluetooth Special Interest Group (SIG), Wireless USB Promoter Group and the USB Implementers Forum. After the technology transfer the
Alliance ceased operations. In October 2009, the Bluetooth Special Interest Group has dropped development of UWB as part of the alternative MAC/PHY, Bluetooth 3.0/High Speed technology. A small, but significant, number of former
members had not and would not sign up to the necessary agreements for the intellectual property transfer. The Bluetooth group is now turning its attention from UWB to 60 GHz.

Alliance and MultiBand OFDM Alliance Special Interest Group (MBOA-SIG, promoted by Intel) merged into a single organization in 2005. The merged group operated as the

After the technology transfer, marketing and related administrative items, the

Ultra-wideband (UWB) wireless personal area network technology may also utilise OFDM, such as in Multiband OFDM (MB-OFDM). This UWB specification is advocated by the
Alliance (formerly by both the Multiband OFDM Alliance [MBOA] and the
Alliance, but the two have now merged), and is one of the competing UWB radio interfaces.
The President of the Mobile DTV Alliance, Yoram Solomon, is also on the boards of the
Alliance and Wi-Fi Alliance.
In December 2008, Ecma International released specification (ECMA-368 and ECMA-369) for UWB technology based on the
Ultra-Wideband (UWB) Common Radio Platform.
ultra-wideband (UWB) common radio platform incorporated MAC layer and PHY layer specifications based on multi-band orthogonal frequency-division multiplexing (MB-OFDM). It was intended for short-range multimedia file transfers at data rates of 480 Mbit/s and beyond with low power consumption, and operates in the 3.1 to 10.6 GHz UWB spectrum.
UWB was promoted for personal computers, consumer electronics, mobile devices and automotive networks.
After joining both the UWB Forum and
Alliance in 2004, in February 2005, it positioned its technology as a third alternative to the technologies promoted by the after groups.
The IEEE 802.15.3a did consolidate 23 physical layer specifications into two proposals: multi-band orthogonal frequency division multiplexing (MB-OFDM), supported by the
Alliance, and direct sequence - UWB (DS-UWB), supported by the UWB Forum.
OFDM is also now being used in the
/Ecma-368 standard for high-speed wireless personal area networks in the 3.1–10.6 GHz ultrawideband spectrum (see MultiBand-OFDM).
Alliance was a non-profit industry trade group that promoted the adoption, regulation, standardization and multi-vendor interoperability of ultra-wideband (UWB) technologies. It existed from about 2002 through 2009.
UWB is a general term for 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 February 2002. UWB is not specific to
or any other company or group and there are in fact a number of groups and companies developing UWB technology totally unrelated to
. Some companies use UWB for ground penetrating radar, through wall radar and yet another company Pulse~LINK used 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 Implementers Forum 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
Logical Link Control Protocol.
UWB platform was complementary to WPAN technologies such as Bluetooth 3.0, Certified Wireless USB, the 1394 Trade Group’s “Wireless FireWire” Protocol Adaptation Layer (PAL) (Non-IP Peer to Peer architecture) and Wireless TCP/IP - Digital Living Network Alliance. Different wireless protocols can operate within the same wireless personal area network without interference. In addition to these, many other industry protocols can reside on top of the
UWB platform. Those include Ethernet, Digital Visual Interface (DVI) and High-Definition Multimedia Interface (HDMI). The
PHY specification has an over-the-air uncoded capability of more than 1024 Mbit/s; the specification was promoted to support wireless video, operating at multiple Gbit/s data rates.
The high speed (AMP) feature of Bluetooth v3.0 was originally intended for UWB, but the
Alliance, the body responsible for the flavor of UWB intended for Bluetooth, announced in March 2009 that it was disbanding, and ultimately UWB was omitted from the Core v3.0 specification.
