Yes.  You must spread the XOs between channels to maximize the overall
system bandwidth, but you can't directly talk to people on different
channels because only have one actual radio.  Most places have APs
connected with ethernet on the backhaul, and so in the office or
wherever, they are already bridging between wired & wireless for you.
