Should I go for 802.11n WAPs keeping in mind the traffic expected?
802.11n & 802.11ac (wave 1 & wave 2).
I understand that enterprise WAPs do not function independently and require WLAN controllers to work.
Not necessarily. Autonomous IOS can still work but one must know the cost vs benefit of running controller-based AP and autonomous AP.
And if I am not wrong then they can be made to function independently after BIOS flash or something, correct?
Conversion from autonomous IOS to controller-based IOS (and vice versa) is very simple.
Each user has two connections (one for laptop, other for mobile phone).
Pffft! Old school. Nowadays one must cater for 3.5 wireless device per person.
