Antenna Diversity

vashishthavikas481 — Mon, 05 Jul 2021 15:20:05 GMT

I have seen that we can change the antenna diversity on WLC to left or right but dont know how access points would behaves after it?

Could anyone help me out?

There are some commands for diversity in Cisco docs but I never needed to play with that:

config 802.11{a | b} antenna diversity {enable | sideA | sideB} cisco_ap—To configure the diversity option for 802.11 antennas, use theconfig 802.11 antenna diversity command

config 802.11{a | b} antenna extAntGainantenna_gain cisco_ap—To configure external antenna gain for an 802.11 network, use theconfig 802.11 antenna extAntGain command

config 802.11{a | b} antenna mode {omni | sectorA | sectorB} cisco_ap—To configure the Cisco lightweight access point to use one internal antenna for an 802.11 sectorized 180-degreecoverage pattern or both internal antennas for an 802.11 360-degree omnidirectional pattern, use the config 802.11 antenna mode command

config 802.11{a | b} antenna selection {internal | external} cisco_ap—To select the internal or external antenna selection for a Cisco lightweight access point on an 802.11 network, use the config 802.11 antenna selection.

If you have Prime then you can use it to change antenna propagation in a graphic view.

Hi Flavio

Thanks a lot for the information you shared J

Yes we too have cisco prime but the problem is the below commands are global for 802.11a/802.11b bands.

Can we change the diversity/gain/mode of any single access point antenna?

I really need to know how they behaves.

Not sure. I believe not, my it is necessary to try, maybe the syntax can change.
