Outdoor APs back-to-back installation

Hello Team,

 

Is it possible to install two AP277 (directional antenna )or AP275 (omni antenna )back-to-back having in mind that they will be in different channel and maybe to neighboor channel for example 36,44.

 

 

Thank you

You plan on both of them being wired to the network?

 

You cannot back to back AP-275s, even if you put them in two different channels, even two different UNI bands, they will still be too close and will interfere. You can put directionals back to back (ala AP-277s) but you still should have ~1m spacing between them.

Yes both of the will be in wired network.

 

The spacing can be also if i put them in a different height for example the one at 3 meters and the other at 4 meters ?

 

Thank you

Not at all for a pair of 275s. For the 277s it will depend on the heading, but because the 277s have coverage up/down they generally need to be in opposing directions, 1m vertical separation would be fine in opposing directions. If they were at 90deg oppositional heading, spacing more like 3-4m would be required. And in all cases you want at least 40-80Mhz separation between channel boundares (so generally different UNI bands).
