We have about 250 2.4 SMs deployed with pretty good success.  Where we have had 
some issues are...

1) direct competitor interference in the band.  It does "OK" but FSK seemed  to 
do much better at it, but probably because of the lesser SNR requirements as 
much as the modulation.  One tower out of 10 has this issue for us.
2) highly concentrated neighborhoods where the neighbors house with his 
wiz-bang overkill home router causes gried.

TIPS:
1) Use Mikrotik routers EVERYWHERE, EVERY customer... to control the 2.4 
"local" environment as much as possible, scan for problems etc.
2) Be conscious about what Frequency boxes are checked in the SMs.  Obviously 
avoid the frequency you have the router at.
        If you don't have a second AP that has a good enough signal (-65 or 
less) and the customer is NOT on the edge of a sector, you can keep the second 
frequency checked
        If you have a poor "second AP" signal OR you have a customer installed 
on a sector edge, check ONLY the one frequency of the "good" (proper angled) AP

Doing this, your eDedects will be happy, and you give yourself the best chance 
for success.  We actually are writing some SNMP backend stuff to help point out 
problems in all these areas, and proactively "fix" them

Haven't even bought any. We're thinking about not even buying any more
2.4 450. It's just too noisy. All the wifi in neighborhoods, customer's router 
interfering with the SM, etc. It's pretty much as horrible as 900 these days.

And if we don't get to keep 5.7 ISM.. things are gonna get shitty. 3GHz is the 
only place to go, so we're gonna be doing a bunch more of it this year.
