Looking online, I haven't found any real or direct answers to this question, but if anyone knows or knows where to find, would an 802.11n router or access point be able to enhance transmission even if it's only client was an 802.11g client because of the N device's "spatial multiplexing"? Thanks.

Assume that I already did an Internet search.

Take a look at wikipedia for the 802.11n standard.

Thanks, Paul, but that did not answer the question.

I think it does, because 802.11n is backward compatible but nothing more.
The enhancements can only be use with hardware, that can handle such things.

E.g. 802.11g doesn't support multichannel transmission, so how should this feature speed up a 802.11g client?

Not to be rude but, 802.11n is not yet a standard. Chances are, we're a year or two away from it being standardized. Which is why, at present, I wouldn't touch "n" with someone elses wireless network. Since it's not a standard there is not guarantee of interoperability between manufacturers equipment.

No, 11n will not "enhance" 11g. The "g" standard is what it is and "n" won't enhance it any more than "g" enhances "b".

Thanks for the replies, and sorry for such late followup on my own posting- life gets in the way sometimes.
I've read some allusions that since a "standard" of N is spatial multiplexing, that N hardware may enhance communication with G devices (not speed up, because you can't transmit any faster than the slowest device, and by enhance I mean improve signal quality) because the N hardware is a better listener and transmitter because of the Spat'Mul'and multiple antennas.
But like Curt says, N is not officially standardized yet.
I should have asked the question better and specified that the object was better signal transmission and not faster data speed.
