WiMedia Alliance

Bluetooth Ultra-wideband 1 The high speed (AMP) feature of Bluetooth v3.0 was originally intended for UWB, but the WiMedia 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.

Bluetooth Ultra-wideband 1 After the successful completion of the technology transfer, marketing and related administrative items, the WiMedia Alliance will cease operations.

Wireless - Categories of wireless implementations, devices and standards 1 *Wireless sensor networks: ZigBee, EnOcean; Personal area networks, Bluetooth, TransferJet, Ultra-wideband (UWB from WiMedia Alliance).

Wireless USB 1 Wireless USB was based on the (now defunct) WiMedia Alliance's ultra- wideband (UWB) common radio platform, which is capable of sending 480 Mbit/s at distances up to and 110 Mbit/s at up to. It was designed to operate in the 3.1 to 10.6 Gigahertz|GHz frequency range, although local regulatory policies may restrict the legal operating range for any given country.

Wireless USB - Development 1 After the technology transfer the WiMedia Alliance ceased operations.[ ooth/Technology/Technology_Transfer/ ] 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 solution

Extremely high frequency - Telecommunications 1 As reported in incisor.tv monthly magazine, the WiMedia Alliance is looking at using the 60GHz range in their road map.[ le=124july2008.pdf Incisor.tv]

IEEE a - History 1 Direct Sequence UWB, which was promoted by the ZigBee Alliance, found its home with TG4a, while Multi-Band OFDM UWB was adopted by the WiMedia Alliance which published ECMA-368 (ECMA is another telecommunications standardization body that is similar to the IEEE).[ 071/episode/14/ Part 5: Ultra Wideband Update: IEEE a and Ecma-368 Podcast]

Orthogonal frequency-division multiplexing - Wireless 1 * The wireless personal area network (PAN) ultra-wideband (UWB) IEEE a implementation suggested by WiMedia Alliance.

Orthogonal frequency-division multiplexing - Ultra-wideband 1 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 WiMedia Alliance (formerly by both the Multiband OFDM Alliance [MBOA] and the WiMedia Alliance, but the two have now merged), and is one of the competing UWB radio interfaces.

WiMedia Alliance 1 The 'WiMedia 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

WiMedia Alliance - History 1 The WiMedia Alliance developed reference technical specifications including:

WiMedia Alliance - History 1 WiMedia Alliance and MultiBand OFDM Alliance Special Interest Group (MBOA- SIG, promoted by Intel) merged into a single organization in The merged group operated as the WiMedia Alliance.

WiMedia Alliance - History 1 On March 16, 2009, the WiMedia Alliance announced technology transfer agreements for WiMedia ultra-wideband (UWB) specifications. WiMedia transferred all 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.

WiMedia Alliance - IEEE 1 The most commendable achievement of IEEE a was its consolidation of 23 Ultra wideband|UWB PHY specifications into two proposals using: Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB, supported by the WiMedia Alliance, then adopted by the USB-IF for Wireless USB and by the Bluetooth SIG for high speed Bluetooth, while the Direct Sequence - UWB (DS-UWB) approach, supported by the UWB Forum, was abandoned.

UWB Forum - History 1 That standardisation attempt failed due to contrasting approaches between the WiMedia Alliance and UWB Forum. On January 19, 2006 IEEE a task group (TG3a) members voted to withdraw the December 2002 project authorization request (PAR) that initiated the development of high data rate wireless standards.

UWB Forum - History 1 The IEEE a did consolidate 23 PHY (chip)|physical layer specifications into two proposals: multi-band orthogonal frequency division multiplexing (MB- OFDM), supported by the WiMedia Alliance, and direct sequence - UWB (DS- UWB), supported by the UWB Forum.

List of UWB channels 1 This List of Ultra-wideband (UWB) Channels describes the physical bands and TFC codes defined in the WiMedia Alliance's PHY specification,[ pecs.asp?id=specs WiMedia Alliance downloadable MAC and PHY specifications] as well as their link to the logical channels used in the higher layers such as the Wireless USB driver.

List of UWB channels - Spectrum Definition 1 Many countries have allocated spectrum for UWB use, with various restrictions and power output limits. The standardized output level for UWB communications is The WiMedia Alliance has defined fourteen 500-MHz bands to divide up the GHz spectrum allocated for Ultra- Wideband communications in the U.S. in
