Hey

Yes indeed the EAP110 Outdoor can work in a mesh mode, provided One (the root) AP is connected via a cable.   If that is the case then the mesh nodes can indeed run wirelessly.

More information is available here

Also worth noting that you will be required to have a SDN controller online to handle the mesh topology, this should be wired into the root node, version 4.2.11 of the SDN is recommended.  The controller can be Software if you have a spare PC, or alternatively buy a OC200 for around £50 / $70US

Awesome, thanks for the help. 

I have two EAP110's running in a warehouse with an OC200 controller already so that part should be covered. I can get a "root" station as well and then hop from there on up over the air. 

Is there a practical limit to how many can be chained in low performance environments? This is some form updating, no video streaming, gaming or anything like that. 

Thanks again for the help,

Corey

The physical limits for mesh are 4x Downlink APs over a max of 3 hops, cant see that being bad if the traffic is limited or low performance.   If you have 2x APs at moment, then they could be 2x roots and therefore you could have 8 downlink.    Examples below

                         /----  2    ------    4

ROOT   -----  1 

                        \----  3

ROOT   ------   1   ------ 2   ----  3

                                          \---- 4

Personally however.. ive only ever gone 1 to 2 hops max and performance for video was grand if that helps!!
