I'm testing the 3700 p with the new Air-ant2513n4p-r right now in Spain, all I can say is this combination exceeds my expectations and design requirements in every category thus far. Can't wait to finish the test cases today and revise the density expectations. Based on what I'm seeing, we can get more channels closer together than we could just 3 months ago using the 3500 series and stadium antenna's. This is getting to be a lot of fun, can't wait for neighbor nulling to make it into the code, it will get better again.
