Wireless Multimedia Alliance |
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 2009.
The Wireless Multimedia Alliance was founded by 2002.
The WiMedia Alliance developed reference technical specifications including:
The WiMedia 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. WiMedia UWB was promoted for personal computers, consumer electronics, mobile devices and automotive networks. WiMedia 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 WiMedia Alliance.
The ultra-wideband system provided a wireless personal area network (WPAN) with data payload communication capabilities of 53.3, 55, 80, 106.67, 110, 160, 200, 320, 480, 640, 800, 960, and 1024 Mbit/s. The WiMedia 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 - 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 WiMedia UWB platform. Those include Ethernet, Digital Visual Interface (DVI) and High-Definition Multimedia Interface (HDMI). The WiMedia 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.
