Works well if everyone has 802.11a/g card. That's been my biggest
concern
with deploying 802.11a recently.

The oft-overlooked 802.11a is great for this purpose when there isn't
enough wiring infrastructure to drop a RJ45 in all the necessary
conference rooms. Whereas 802.11[bgn] has only three (or four,
depending on who you quote) mostly non-overlapping frequencies -- even
less when MIMO is in use -- 802.11a has eight *completely*
non-overlapping standard channels. In nice open conference hall space
with at most two walls in the way, the rated shorter range of 11a is
actually not so noticeable because of the lack of radio noise.
2.4GHz is soooooo last decade. ;)
(The 802.11[bgn] density where I live is so high that I resorted to
installing 802.11a throughout my house. Zero contention for airwaves
and I can actually get close to rated speed for data transmission.)
