If you are starting from no 5.7AP's you could get away with with no sync, but without a baseline you will not know how much not having sync will hurt you. Having been running 3 5750AP's on a mountain top for over 5 years my recommendation is to use sync.
If you only have one tower and no other Canopy AP's within earshot, you can do it the cheap and easy way by setting one AP to generate sync, and the other two to receive sync on the timing port. Tie the 3 timing ports together on all three AP's and they will be in sync with each other.

Since you have 6 non-overlapping channels that you can use, with only three radios, you do not need the CMM timing. You can have each radio generate sync. This changes if you have other canopy 5.7 gear on the towers. Marco Coelho On Sat, Aug 21, 2010 at 11:03 PM, Josh Luthman <[email protected]> wrote: > You can use a parasitic thing from Packet Flux.
