Most networking groups have a wireless guy, maybe two – you might be that person. For years, the rest of the campus network group hasn’t really had to think about what they plugged into the network. Give them a gig port, PoE, probably set up a VLAN and that’s it: wireless sorted.
Because when it all came down to it, it didn’t matter how many wireless users connected to the access point because only one device, the client or the access point, could transmit at one time. What’s more, a single wireless client is not going to tax a gig port. In fact, the more clients there are on an AP, the less traffic ends up on the wire since they spend more time trying to get a timeslot to transmit, like the seagulls in “Finding Nemo” yelling “Mine, mine, mine.”
