Early comment

Certified Wireless USB can operate in two way:

Coexistence Wireless USB operates on top of Wimedia UWB PHY - Wimedia UWB MAC - Convergence Layer. Pure Wireless USB operates directly on top of Wimedia UWB PHY.

I wonder where this distinction comes from. Currently there's only 1 Certified Wireless USB implementation. This seems to be the one referred to here as Coexistence Wireless USB.

Probably this refers to current CWUSB model where CWUSB devices can be WiMedia MAC&PHY aware and participate to the WiMedia MAC beaconing and other channel management or CWUSB device may be not aware of this and are only understanding CWUSB related data transfer (sending WiMedia beacons according to instructions sent by host or not sending WiMedia MAC beacons at all). CWUSB hosts are always WiMedia MAC&PHY aware to faciliate coexistence with other PALs using WiMedia UWB.

Feel free to add a UWB column to the OFDM#OFDM system comparison table. Mange01 11:57, 17 July 2007 (UTC)[reply]

Dead Technology ?

WiQuest was an early player in Wireless USB.
Wisair chipset looked promising, but products are near-impossible to find at the end of 2011.
Google Shopping finds 3 items from Q-Waves, but only in brokers probably not stocked.
Cables Unlimited was taken over by Cables To Go who still list WiMedia VGA/HDMI links, but their USB-USB link is 2.4GHz - not this standard.
Wimedia also seems to have been overshadowed by 2.4GHz for audio - many wireless headphones, microphones , E-mu Pipeline etc.

Just spotted Warpia ConnectHD - a new product announced yesterday ! Perhaps it's the start of a deluge ?

Wireless USB FAQ is intesting - not sure it's a Reliable Source (blog).

"The first such flavor was released by Cypress Semiconductor in 2003 and is technically the only version that can be called WirelessUSB [tm] because it is trademarked. It is a very low-speed, limited "variant" of USB that was primarily targeted as a replacement for Bluetooth. Its key application lies in the wireless connections of human interface devices (HIDs) such as mice and keyboards. It uses a proprietary 2.4 GHz radio with a datarate of only 62.5 kbps."

Interesting!

Disbanding

There were earlier reports that WiMedia alliance was to be disbanded by end of 2009. However their website contains neither the disbanding announcement, nor any new developments since end of 2009. What is the current operational state of WiMedia Alliance? --Dmitry _{(talk•contibs)} 10:40, 10 January 2012 (UTC)[reply]

Common Signaling Mode

The term "Common Signaling Mode (CSM)" is used in this article as a potential solution to the two PHY problem. However, there is no link to an article on CSM. I was also unable to find an article on CSM through disambiguation. Can anyone help?
