Faster Wireless Multimedia Streaming
prostoalex writes "The Wi-Fi Alliance approved Wi-Fi Multimedia (WMM) technology that allows packet prioritisation to the multimedia data streamed wireless LANs. Broadcom already announced that one of their access points and one reference design are WMM-certified. Other news outlets report that WMM will accelerate Wi-Fi adoption in consumer electronics and mobile devices."
Isn't this just Quality of Service? Surely any decent wireless router manufacturer that doesn't already support QoS could add it with a firmware update. Or is this another scheme to get me to buy new wireless routing gear (first b, then g, now WMM)?
What am I missing here

I wonder what the RIAA/MPAA will have to say about this...will they require that the streams be encrypted?
It'll be interesting to see how this plays out with those lawyers.
Tell the truth and you won't have so much to remember.
I'd be interested as to how they define which packets are multimedia, and which are data/text-based. It seems to me that there would have to be some sort of identifier on each packet in order to set a priority. As such, it sounds like it could easily be streamlined into a DRM scheme, so I wouldn't think that the RIAA/MPAA would mind at all.
Of course, I'm not a packet expert, so this ability may be available already...
Doesn't this lead to a new type of DOS attack? Granted, this wouldn't be used in a corporate setting, but it could seriously much around with the enduser experience if all sorts of high priority packets shut off other traffic.

With all the discussion about city wide WiFi networks in Grand Haven, Philadelphia, Redmond, etc and disputes over WiFi right of ways at universities and stadiums, it is becoming more obvious that WiFi will be eroding the markets of tradition broadcast technologies... radio, television, cellular.
When I was at SXSW last year, not only could you listen to the authorized SXSW iTunes playlists, but hundreds of Mac using convention goers were sharing their playlists via Rendezvous.
With standards like WMM and applications like Skype, have we finally taken the airwaves back?
at least not 802.1p , It works on the radio level (PHY)a ckoff.pdf
:) You can do the same in Linux today. Hell, thats how 802.11 DOS works (small traffic occupy whole band, just send first and pretend you send something big)

all you have to do is make sure that multimedia sending device gets their backoff timers boundaries set lower than the rest of the wifi boxes on the channel. That way they will be the first to occupy the band if in need. Thats how Cisco handles QoS in VOIP WiFi phones of theirs. Its 100% compatible with the receiver, only transceiver has to support it.
google has it all
As some of you guessed before this whole certification is pointless
Go grab those torrents.
If you update your linksys wrt54g to the latest firmware, and use one of the many methods out there to access the wirless driver that runs on an embedded linux os you can execute /usr/sbin/wl
one of the supported commands returned is
wme Set WME (Wireless Multimedia Extensions) mode (0=off, 1=on)
I'm guessing that the included broadcom radio is the one that supports this.
Remember that you are unique, just like everybody else.
