Hello, i want to make a wireless link 5.8ghz, for wisp used, is the 532A powerful enough for handle 2 Ubiquiti Super Range 5, the unit dosen't has 400mhz processor speed.?

You can use 2 high power card with 48 Volt adaptor.
You need the high CPU clock rate when you need to pass more throughput.

thanks, but how do i high CPU clock rate?

it should already be at 400Mhz, that's max.

normis right, the new 532 series was already at 400Mhz.
for the old ones, you can try overclock it.

Will the Rb532a handle (4) Ubiquiti Super Range 5 cards? I plan on using (4) 90 degree sector antennas for backhaul.

IMO you should use two RB532A with 2 XR5 each one.
