1. Can I have mesh setup without using the Omada controller?

2. If I use the Omada controller just to setup the mesh then turn it off completely. Will there be any consequences?

3. As EAP 225 is dual band, can i have it use the 5ghz frequency for the mesh connection or it chooses automatically between 2.4 ghz & 5ghz?

1. No. A mesh network needs to be configured using the controller which oversees the topology of the mesh.

2. Yes and yes. You can set up a mesh network and then shut down the controller. The consequence is that the mesh will not be re-configured automatically if a node fails (not relevant if you use only two EAPs).

3. A mesh always uses the 5 GHz band for links between nodes. It could not work over 2.4 GHz since the bandwidth in the latter is much smaller than in the 5 GHz band.

Further notes:

• To work reliably, a mesh node needs a free line of sight to the uplink node.
• A mesh will reduce data bandwidth for 5 GHz clients by roughly ½ per mesh node (data sent from a client must be sent to the uplink node).
• A mesh will not increase total user capacity; the capacity of all mesh nodes linked to a root node together is the same as the capacity of only one EAP.
