Uncommon Thinking for the Common Good™Stay
Is a frustrating topic for sure. Even if you have a good wireless guest network, many vendors/visitors and even some faculty/staff/students just prefer to pull their own devices out and use “their own WLAN” anywhere and everywhere- it’s just part of their lifestyle. And yes, frustratingly our friends at Verizon and AT&T who make these units increasingly cheaper could give a rip about interference or policy of the places the gadgets get used. My own rant: http://wirednot.wordpress.com/2013/02/25/mi-fi-not-kind-to-wi-fi/
Prevention is great if you can effectively spread the word, but the need to have a mitigation strategy is inevitable- as is the occasional scenario where a class or meeting (or stadium event) has its campus wireless crippled by people “bringin’ their own Wi-Fi”. Sadly. Our lot in life is to bear the criticism that the WLAN sucks when we’re simply a victim of physics, until we can deal with getting the devices eliminated.
The move to 5 GHz by more devices helps, but doesn’t eliminate the problem as some Mi-Fis are showing up in 5 GHz as well. To me, this is just one of the negative (to us in the Enterprise WLAN business) effects of the general consumerization of IT, and of WLAN specifically. There is no fix, there is no answer, so you need a strategy that combines:
· Education- frequent and non-threatening messages of why these devices are problematic
· Get partners- IT staff/Deans, etc beyond the WLAN admins have to buy in and help with the message
· Enforcement- when you can without obsessing about it
· Tolerance- some you just have to let slide, either politically or because it’s just not worth the battle
And you have to be able to apply these in varying weights depending on the situation. Nothing with wireless is simple any more.
One man’s O-pinion.
