While I agree with all the justifications offered below, I don’t recommend going there if you can avoid it. If somebody wants to challenge a business case based on those things there will be plenty of opportunity to do that. I value a good business case more than most, but a determined bean-counter will always get their way if you make it about counting beans. Remove them from the equation if you can.
Instead, it’s pretty easy to convince IT leaders that administrative approaches to these problems rarely work and frustrate the user community. The network has to work, and we want our users to be happy, so administrative approaches aren’t desirable. Once the leadership has agreed to that general principle, you don’t have to weigh the tradeoffs between technical and administrative approaches each time a new challenge emerges. Challenges with technical solutions get the technical solution and the network just costs what it costs. Challenges without technical solutions get administrative stop-gaps until a technical solution emerges.

Sessler Sent: Thursday, October 19, 2017 1:39 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Wireless printers and other devices in residence halls 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.

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.

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.
