Controllerless Networks

I need to configure a Mesh between two points, one it's outside and the other inside, so it is posible to do this using one IAP 175 and one IAP 105 or one IAP 275 and one IAP 205.

Mesh is not supported on the 200 series APs till near the end of the year.

You can do Mesh between an IAP-175 and IAP-105.  Setting up Mesh is described in the Users Guide. Your results; however, by placing one AP inside and one outside will vary depending on construction materials.  You may be better off placing both APs outside.  Generally, it is also a good idea to match antennas between the two nodes.

Is this just for a point-to-point connection?  If yes, have you considdered the MST200?

 It's not a  point to point connection so the MST200 is not what we need. so I'll use IAP 175 and do a site survey to know the best way to interconect.

Thanks for your answer,
