Talk:IEEE 802.11

on channel bandwidth

As far as I know, the channel bandwidth in DSSS is 22 MHz (11 Mchips/s). The same channel structure is used for 802.11a and g (which mainly use OFDM modulation scheme). Thus, do not you think that in the table "protocols" we should put "22 MHz" on channel bandwidth OR "20 MHz (nominal bandwidth)"?. This last one could be appropiate, since the standard uses the term "channel spacing" for this issue. Waiting for your responses to edit the article.

Wi-Fi again

Egad, not even a wikilink to WiFi, which is the term most people (albeit not totally precisely) use for this family of technology? The split between the two articles makes sense, this one for IEEE technical standard and that for the trademark. But not even mentioning it here, let alone a short explanation of the relationship is quite odd. Any reason for this? W Nowicki (talk) 17:26, 9 June 2011 (UTC)

Or did you mean Wi-Fi, which is linked in the body of the article, and now the lead? --Wtshymanski (talk) 18:02, 9 June 2011 (UTC)

You are right, the dash seems precise, and thanks for stating what seems accurate: that these are the standards and Wi-Fi is the product name. That was quick. W Nowicki (talk) 21:46, 11 June 2011 (UTC)

Merge from Regdomain

Regdoman is a one-paragraph definition that might be better here in this article to give it context. --Wtshymanski (talk) 22:12, 14 November 2011 (UTC)

The modulation of 802.11ac is OFDM, same as 802.11n

This post is in reference to the table below the topic "Protocols" and specifically to the column labeled 'Modulation'. The 802.11g, n, and ac protocols all use OFDM as a modulation. They also all use QAM encoding to obtain multiple bits per symbol on each OFDM subchannel. The change in the column from OFDM for 802.11n to QAM for 802.11ac is misleading. I think that instead all references to OFDM in that column should read OFDM - QAM as they are both properly referred to as modulations.

This change was made on 1/27/2012.

802.11ac speeds in table are not using the same "data rate per stream" as the other IEEE protocols

Whereas 802.11n correctly calls out a max rate of 150Mbps per stream. The rates in the 802.11ac aggregate bandwidth from all of the streams. — Preceding unsigned comment added by Halichopter (talk • contribs) 02:08, 29 January 2012 (UTC)
