[edit] Reason for page

I'm adding this because this information is missing from wikipedia. 802.11a channel/frequency mapping is difficult to find and I expected to find it from Wikipedia. Information on channel/frequency mappings should be readily available. I'm hoping this article will find a better place or name, but still exist in wikipedia, preferably 802.11a/b/g/n channels all on one page. --Joneskoo 16:45, 22 September 2007 (UTC)

I'd also like to get references to some document that defines this channel naming scheme. Apparently on 5 GHz it is 5000 MHz + channel * 5 MHz, for example channel 36 = 5000 MHz + 36 * 5 MHz. I used http://www.moonblinkwifi.com/80211a_frequency_channel_map.cfm as a source but I'd really like some better reference to the article. --Joneskoo 16:48, 22 September 2007 (UTC)

[edit] France

Haven't the channel restrictions in France been removed in the meantime? 212.213.204.99 05:18, 2 November 2007 (UTC)

Find a verifiable source and change the text in the article. -- KelleyCook (talk) 20:51, 3 January 2008 (UTC)
Done - 82.123.102.83 (talk) 17:10, 13 March 2008 (UTC)

Maybe add Israel to the first table (channels 3-9)? 87.194.223.183 00:51, 4 December 2007 (UTC)

Give a definitive source (either a link to the Israeli law or an IEEE citation) and then it can go in. -- KelleyCook (talk) 22:04, 4 December 2007 (UTC)

[edit] Wrong information

Please be careful regarding assertions of legally approved channels... (in the first section) References to 802.11 standards do not help much (not even 802.11-2007) as even this document is actually about three years old since I and 300+ other 802.11 members wrote it. Regulators (esp Japan and a couple of EU countries) have made changes to the channels in the last three years. To be crystal clear referencing 802.11 is not proper as it is not a regulatory organizarion and it lacks any legal authority to set channels. 802.11 merely reports what the status is at the time of the standards draft which is three or more years earlier them the date... I tried to make updates but now it appears that I am blocked and I do not want to refer to myself as an authority reveling who i am, less the regulatory rnvironmrnt change and litigation happen do to the section not being updated... —Preceding unsigned comment added by 76.118.191.206 (talk) 03:48, 2 January 2008 (UTC)

You're changes are not being blocked. The message I left on your talk page simply was stating that Wikipedia demands verifiable sources. I realize that by its very nature of being a multiple committee driven multi-year process, the IEEE 802.11-2007 information is out-of-date. It would be more than welcome to have newer and correct information. But any changes that you add needs to be verifiable, such as was included with the recent change to the Japan 5Ghz section. A secondary problem is that you can't put a blanket "This is Wrong information" statement, even if it is true, as it both has a NPOV stance and breaks the Wikipedia:No disclaimers in articles policy. The article already states three times that "These regulations are subject to change at any time." Let me make try and compromise by make that more topical -- KelleyCook (talk) 20:51, 3 January 2008 (UTC)

[edit] Asia

Asia is not a regulatory domain!? Find me a country on this planet called "Asia" please remove it —Preceding unsigned comment added by 76.118.191.206 (talk) 18:28, 3 January 2008 (UTC)

Gone, next time please WP:Be bold -- KelleyCook (talk) 21:01, 3 January 2008 (UTC)

[edit] 5GHz Channels in the US

According to http://www.fcc.gov/oet/info/rules/part15/part15-9-20-07.pdf page 130 the bands 5.15-5.25 are available for unlicensed use at 50mW, 5.25-5.35 and 5.47-5.725 at 250mW and 5.725-5.825 at 1W. Is there another reason channels 52-64 are listed as No for the US? (I'm no expert in RF so not editing the article)

[edit] Spain has more channels

Spain, like the rest of Europe, allows channels 1-13 (instead of 10-11). I have found some places where it says it is only channel 10 and 11, and I don't know why.

According to note UN-85 in CNAF (spanish legal frequency table) you can use 2400-2483,5 MHz for indoor wireless data networks (100 mW EIRP). http://es.wikipedia.org/wiki/CNAF http://www.mityc.es/Telecomunicaciones/Secciones/Espectro/cnaf/

Moreover, any modern wifi equipment legally sold in Spain supports channels 1-13. —Preceding unsigned comment added by LatinSuD (talk • contribs) 15:56, 2 May 2008 (UTC)

I took out the two columns which someone edited back to the (out of date) 802.11 doco. Thanks for the reference. -- ~~
