So I have a WIFI/client application which has some specific issues, in that several devices need to absolute priority.

Fortunately, i'm able to prevent MOST devices from joining the network, but I need to be able to further prioritize traffic, in order to avoid interference for the main priority app.

  1. are there particular methods in Wifi APs which would allow me to set a QOS level for particular MAC IDs, prevent lower priority devices from having any preference, etc?

  2. is there a particular class or series of AP which I should be considering to gain higher control over the network?

Currently we're running both 2.4 and 5ghz, are running on some ENgenius and Ruckus devices. However, I' wondering if there are different classes of APs which offer more 'under the hood' management?

    First, doing anything based on a MAC address is pretty pointless because it is so easy to spoof a MAC address. Second, You can set QoS on the layer-3 packet, but it sounds like you want a non-existent layer-2 frame QoS. The 802.11 protocol requires fair sharing of the airwaves, and it requires devices to yield to other devices wanting to use the airwaves. Only one device at a time can use a frequency. That medium belongs to everybody. – Ron Maupin Nov 13 '16 at 18:27

    There are QoS mechanisms for wireless, but only if the client agrees to use them. You are at the mercy of unmanaged clients who don't play by the rules. – Ron Trunk Nov 13 '16 at 19:05
  • How would one impliment the QoS for wifi? is this an app which the client needs to run? Is it something which can be implemented on iOS devices? – frank ankersly Nov 13 '16 at 19:34
  • Many (wired) APs at low power serving as few devices (small physical areas) as possible would be one approach to minimizing airwave contention. It's also general good wifi design practice. – Ecnerwal Nov 13 '16 at 22:51
