Interference Mitigation in a Hospitality Network?
I have a wifi deployment at a hotel that sees a large amount of noise, both externally and within my network (read: 168 reported rogues over 24 hrs in a 28 AP deployment, mix of 7982 and 7762). These APs are mounted relatively close to each other, so I can saturate the property, and turn down power to reduce internal interference. About 1/3 are root, and 2/3 are mesh, with no more than 1 hop, and all mesh links >20dB.
I'm looking to mitigate interference as much as possible. My needs are such: I don't care about legacy devices (.11b), and am primarily focused on mobile devices, though laptops shouldn't suffer.
I have 2.4GHz set to 20MHz channel width, and 5 set to 40. I'm using 1, 4, 8, 11 for 2.4, and everything over 100 for 5. I've adjusted power on 2.4 several times, but can't find a happy medium. 5 is set to full. I have bss-minrate set to 5.5, and smartroam set to 3 (should encourage roam at m looking for any input on this config, and things I should tweak. I apologize for the book. Thanks for any help!
