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. -Brian From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Jeffrey D. 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.
