I've added more detailed info about 802.11 frame types, which I think would be too long and too detail to be crammed in single subsection of the article. Currently it is not linked to this article (orphaned), but IMHO should be linked.

Part of the history section of this article reads:

802.11 technology has its origins in a 1985 ruling by the U.S. Federal Communications Commission that released the ISM band for unlicensed use.

And references source [1]. Neither the current nor archived version of source [1] actually references 802.11 or any court ruling by name. Should the reference be removed? Trickypr ( talk) 11:43, 31 May 2022 (UTC) reply

What exactly is a "spatial stream" ?

The term appears in every one of these Wikipedia 802.11 articles, 802.11n,ac,ax, and referenced MIMO links, &tc. (and everywhere else on the internet). But invariably, the only definitions of the concept are just substitutions of other words, like "multiplexing". And some hand-waving about doing it with separate antennas.

That doesn't explain even fundamentally what it is and how it's accomplished. For later 802.11 variants (802.11ax) it's easy to understand segregation of OFDMA subcarrier bands, much like channel bonding, that's a good starting point for the concept. Otherwise, for earlier 802.11 levels where "spatial stream" originated, what is it, how is it accomplished.
