Is There a Place for 802.11a? - Computerworld

I've started writing a column for Computerworld. My first article has been posted to their site. I'll be covering the wireless field and hope to cover a lot of topics in this forum. Of course if you have ideas for me to write about, or feedback on my articles please feel free to email me.

I hear it all the time: "802.11g gives you the same throughput as 802.11a, so there is no reason to upgrade to 11a hardware." But that statement doesn't take into account a fundamental advantage of 802.11a: radio frequency diversity.
