We currently have a lot of RB493AH out in the field at tower sites. When looking at the 2011 series, I see that they should be a fit faster, and cheaper as well.
But, I also see the description saying its an "indoor device". We use the 493AH in a normal case and inside a metal job box in the Florida sun that has fans but certainly gets warm. So, what makes the 2011 an "indoor device" ? Anybody of real world experience in an outside tower box as I have described?

I have had similar issues with the 751 and 951 units. Signal strength is sporatic and throughput is initially ok, then quickly drops off to zero. I switched to 2011 series and have never looked back. MT keeps avoiding questions about this on the support forums so it's highly unlikely that they will ever admit the root cause. My customers were unhappy with some of the units I deployed, so I just quit using them alltogether.
