802.11 Radio Profile - Smart Antenna

Just looking for clarification:


Under the 802.11a and 802.11g radio profile in 6.5.x - advanced, there is a setting called "Smart Antenna". Is this option the one that handles the AP-335's understanding whether they are mounted horizontally or vertically dynamically? Couldn't find this option in the User Guide.

same question for 303h. What does Smart Antenna Feature exactly do? 


Re: 802.11 Radio Profile - Smart Antenna

The "smart antenna" feature applies to AP-335 only.

It does not affect antenna patterns, and does not change the fact that the 335 is optimized for horizontal (ceiling) mount.

It simply enables a feature on the AP-335 where the software will dynamically select between a vertically and horizontally polarized antenna element for each of the four radio chains of the 5GHz radio.

The antenna patterns for these elements are roughly the same, but by selecting the optimum combination, we can improve the signal quality (SNR) in both transmit and receive direction, which may result in a higher sustained datarate (MCS) for a given link.

That's all.

Will turning this option on an ap-group with mixed models of APs have issues?  We're adding a few AP-335s in areas, but don't really want to put them in their own ap-group if it isn't required.

Nope, no problem.

The feature will improve SNR for connections between the 335 APs and their client devices. It does not affect anything else.


Re: 802.11 Radio Profile - Smart Antenna

Is this feature supposed to be enabled by default? We just upgraded to and the feature is enabled.  We are running 205 and 305 AP's.  Any issues running with this enabled?

No, because it will only be used by 335s.  On other models it should have no effect.
