There's so much marketing coming out of wireless companies these days, because there isn't really much that distinguishes one WiFi manufacturer from the other.
The Ruckus device is a Wifi diversity switch, using multiple antennas (7 or more).
The truth is that they will have to sort this out at some point and I am of the opinion that it would. I envy the astronauts who will be going to live on Mars and the Moon soon. They will have very little competing signals and pretty damn good reception.
