Thanks to all of you for your help with my question. Considering the budget, I wanted to go for IAP-93, but then based on my understanding from the responses the computers with capability of accessing only 2.4 band won't be able to connect if a new computer has already connected itself on the 5 band; as both bands won't work together - right?
On another note, could I deploy both IAP-93 and IAP-105, one each?
