[edit] disambig

"Note: this WDS is different from the WDS implementation by Cisco, which stands for Wireless Domain Services."

I think that deserves a disambiguation note at the top of the page, but don't think it should be on the wds page.

I looked all over but couldn't figure out how to do it, and couldn't find a page that used it. http://meta.wikimedia.org/wiki/Meta:Disambiguating_pages http://meta.wikimedia.org/wiki/Special:Disambiguations http://meta.wikimedia.org/wiki/Disambiguation http://meta.wikimedia.org/wiki/Special:Search/Disambiguating_pages None of those helped at all.

I don't see a need for disambiguation here. First, the link to Cisco's Wireless Domain Services is an external link, not a wikilink; second, disambiguation is already happening at the WDS page. I've left the clarification in, but IMHO there's no ambiguity to disambiguate. DoctorElmo 06:35, 14 July 2006 (UTC)

[edit] WPA

"WPA cannot be used due to the dynamic nature of the encrypted key."

It really seems like there are a lot of opinions (!) regarding WPA and WDS. Wikipedia mentions that WPA cannot be used. Apple states in http://www.apple.com/support/downloads/airportexpressfirmware611formacosx.html that a firmware upgrade (from december 2004) solves this. http://wrt-wiki.bsr-clan.de/index.php?title=WDS_Linked_router_network currently mentions that it doesn't work between DD-WRT and Airport Express (which might be expected with different vendors). http://rgbdream.com/?p=44 mentions (a bit down) that it actually currently is working in different setups...

[edit] Relay vs Remote

So the difference is that one relays data, and the other "passes on connections"? What does that mean?

Connections between "clients" are made using MAC addresses rather than by specifying IP assignments

Why is the word clients in quotation marks? Is this an ironic usage of the word? —Michael Z. 2007-03-03 17:28 Z

[edit] multiradio and throughput

The article currently states, "Wireless throughput is cut approximately in half for each WDS repeating 'hop'." Www.meshdynamics.com has a bunch of glossy advertising literature that talks about using multiple radios to increase bandwidth and decrease latency and jitter. Basically, they say that with a dual radio access you point, you can have one radio handling the client services and the other radio handling the backhaul (the mesh infrastructure). If you add a third radio, you can have a full duplex connection for the backhaul (one radio transmits, the other receives).

This is clearly something that should be mentioned in the article, but I am not very knowledgable about WDS and even if I was, I wouldn't want to cite meshdynamics advertisements as if they were fact. I assume there is some real reference documentation, perhaps a published paper, which describes WDS with multiple radios. Could someone who is actually an expert in this field please edit the article so that it references that document? Thanks. 71.231.66.55 00:46, 23 July 2007 (UTC)

About the Wireless troughput cut in half for each hop, I really doubt this, this is only true if you have one hop, if you use 2 hops, then it is divided by 3, and 3 divided by 4. This makes more sense, since one radio channel is divided by time sharing between these units.

[edit] Throughput

I also don't get the inversely proportional to 2^hops bit. Once it has halved, because the first hop can only receive and send half it's throughput at the same time, the second hop receives (assuming the same capacity) only half it's capacity, and so can send all of it simultaneously. Why does it not just half, once, and the whole network can send, at any large hops, half the Acess Point's capacity??? —Preceding unsigned comment added by Jan.groenewald (talk • contribs) 14:27, 13 September 2007 (UTC)

[edit] Implementations

This list has become unencyclopedic. Its value is debatable and I'd like to clean it up after hearing some input. E_dog95 ^Hi 05:32, 25 November 2007 (UTC)

[edit] Wi-Fi Alliance Certification

Why don't they certify it? I'd at least would like to see a citation for that. WDS isn't mentioned anywhere on Wi-Fi Alliance either. --ArtifexCrastinus (talk) 02:42, 10 April 2008 (UTC)
