Wifi replace fixed cabled systems no way!
Why tie up limited air space when you have fixed systems that need power anyways and with POE your security cameras just need 1 cable and it makes it harder to jam them.
and 8 GIB max is that per AP when 1 device is getting all of the bandwidth? Will the AP have 10 GB-E ports? USB 3.1 wifi sticks? PCI-E X4 wifi cards? SFP ports?
or what about just wiring systems gig-e to an switch that can have GB-E 10 or even fiber up links.
