You need to know the reason for that plan. If the clinic had a lot of shielded walls as is typical for clinics that had X ray machines then it takes more access points.
Also, if the owner DEMANDED that it always work in every corner, again, you blanket the floors.
In parting, some advice from my friends. Ready?
"Don't fix things that work."
So, there is this 2 floors clinic where they are using about 10 wireless access points, which is kind of too much for such a place !
is there any kind of way to reduce the number of those AP ?
And is replacing them with better ones will solve the problem ?
