As Brian said, it is nice in theory; the reality is you don’t get the capital 
increase or the personnel.

Or, spend 30+% in capital investment vs adding more workload to existing staff 
to track down rogue devices – which is probably more on par with what the bulk 
of our realities are.

I am being pressured to support IoT devices over the previous -72dB/2.4GHz 
AP-in-hallways design with little to no funding to upgrade more areas to our 
current -50ish/5Ghz more localized radio design.  CapEx goes to admin systems, 
not infrastructure.

The way to present that 30+% increase in capital investment is to talk about 
the FTE resources it frees up, caps, or eliminates i.e. by increasing density 
the need for residential life/IT to police personal devices is significantly 
reduced/eliminated, freeing up or eliminating [x]FTE for other mission-aligned 
activities. There isn’t a CBO/CFO alive that doesn’t react well to proposals 
that cap/reduce FTE investments in exchange for capital investment. Hardware 
doesn’t require 34% benefits, raises, and so on.

Spend $10,000 for 20 more APs, or spend $650,000 in salary/benefits over five 
years to hire an RF engineer to go out and find these problems. Even when 
pitted against a $20/hr user support position, it’s still $10,000 for 20 APs, 
or $265,000 salary/benefits over five years for that person to do policing.

In other words, you have to add a lot of APs before you get close to the cost 
of a single FTE.

You’re correct, but it just sucks that we now have to justify a 30+% increase 
in capital spent on wireless infrastructure for something that (at least 
according to those who manage the budgets) worked fine 5 years ago, AKA why do 
you need to put 50 APs in a building that once had 30?

If you move your design planning toward dense 5GHz and designate 2.4 as a 
legacy wasteland, these devices have little impact. Even if these devices more 
toward 5GHz, the abundance of channels coupled with low signal propagation and 
vendor channel management e.g. DCA in Cisco speak, greatly enhance coexistence. 
Since you mention Cisco, use of CleanAir equipped APs in residence halls (even 
in small quantities) provide significant RF visibility, and you’ll know exactly 
what’s out there and impacting your environment.

That’s a long way of saying you will never legislate these devices out of 
existence, and it’s far better to invest resources in technology that help with 
coexistence vs expending energy on confiscating/banning them.

Subject: [WIRELESS-LAN] Wireless printers and other devices in residence halls

I wanted to get an idea how everyone is handling students bringing in all types 
of wireless devices, which are basically access points.  We have so many 
printers, TVs, Roku devices, game systems and who knows what else out there in 
the student rooms and these devices are causing issues with our campus wireless 
network.

Do you allow these devices on your network?  If not, how do you prevent the 
students from having them?

I have Cisco wireless controllers where I can block rogue APs but that keeps 
the APs which are containing the rogue AP from servicing the clients and I 
don’t have dense enough coverage to be able to do this for every rogue device.

Thanks in advance
