Hello Jim,
But there is no way that 8 802.11 cards in a single system is useful.
Four, perhaps, with a lot of work, and only if all but one of them runs in 5GHz.
But *8*? NFW.
Allot of people have written that they are interested in six -- it isn't much difference for us to make an eight port. NFW for you, but others need this. It does appear a bit extreme, but people said the same when we made the four port mpci to pci -- and they sell quite well.
John - Unfortunately selling to happy and excited buyers is absolutely no guarantee that these buyers won't discover the limitations at layer 1 (the wireless layer) once they deploy and load up their radios with moderate-to-heavy "real-world" traffic. I think you take (and I mean no disrespect to you - IMHO Mikrotik makes some GREAT products and I frequently recommend Mikrotik products to my clients) an unacceptable business risk in representing that a WISP can run 8 radio cards in one box. This can easily come back to "bite" you. These same happy buyers can quickly become bitter because they did not understand (and you did not explain) the consequences of putting this many transmitters so physically close to this many not-very-selective receivers.
None of your happy "quotees" indicates that they've got a many-radio router actually deployed and successfully handling real-world traffic loads.
Again, please keep up the good work making the great Mikrotik products but please (PLEASE!!!) look furhter into the layer 1 consequences of cramming so many inexpensive radios so closely together.
Respectfully,
jackThe reduction in available power to each slot is also ... troubling.
What "power" are you talking about? PCI standards support this amount of power -- read the specs. The onboard power controller changes 5V to 3.3V -- and very efficiently.
Below are four cut and paste from the equipment-l and isp-wireless list -- just so you know that I am not making it up!

Guess all we would need to do is mount a Micro-ATX 2ghz processor board at
the top of the tower, and be done with all the extra radios now! Thank John!
Who else in the US aside from Eje carries your products please? Can you list
all sources ?

John,
That is absolutely wonderful :-) but what do you suggest we use to power that puppy with? Do you have something with enough CPU horse power to push those 8 cards as I have started putting all my gear on the towers?
Thanks, Mac

RouterBOARD 18 -- 8 port mPCI to PCI board (Extreme)

I think it's great to see this out now... If you've got sectors and
pass-through back-hauls, you've got 6. Then you've got a couple extra ports
for redundant backhauls or extra capacity.

John, Can I trade in my unused 4 port version :)
To think I just recently bought a 4 port and needed 6.
