Just as a followup as I didn't really explain very well before, the rate control doesn't actually affect the WLAN connection speed (i.e. clients still connect at up to 11mbps), it actually enforces a maximum data throughput rate to each client once they are associated which is where it becomes very useful.

I use Denso over S/A tape for permanent installs, it's horrible messy stuff to deal with when you have to take it apart again in a few months though.
