Pre-n or not Pre-n

[Dan]

Well, that depends on what pre-n/n manufacturer's gear you are using.  Not
all of the current pre-n MIMO chipsets use beam-forming.

Check out: http://mrtmag.com/mag/radio_vendors_not_waiting/

"The Wi-Fi MIMO market has separated into different technology camps. For
instance, Belkin and Linksys offer MIMO products based on Airgo's chips and
its spatial multiplexing technology, and Netgear is incorporating both
Airgo's chips and additional smart antenna technology, known as sectorized
antennas, from Video54. However, D-Link is using chips from competitor
Atheros Communications, which is incorporating beam-forming smart antenna
technology."

I'm thinking it would be OK to modify or replace the antennas on the
Airgo-based boxes at least.

Cheers,

Dan
