Currently I have a network with 6 APs 1242 and one controller WLC2106. I have identified at least three points were the coverage is not good enough and I will add more APs. My question is for problems or limitations I should care about to add a second controller and APs 1131.

The customer is a factory and the 1242 features are good for the hard environment into the factory, but the problems are in the offices area, also new offices will be built in the following months. I don't like to waste money adding more 1242 APs, antennas, cables, etc. if the APs would be installed into the offices.

Thanks in advance.
