Antenna Questions for the Wireless Gurus

Unanswered Question
Aug 27th, 2010

I am reviewing a design for a Hospital Campus environment with approx. 400 "1252AGs".  These APs have the AIR-ANT2430V-R (for 2.4GHz) and AIR-ANT5140V-R (5 GHz) antennas installed in them.

But, here is the kicker.

Checking their configurations in WCS I noticed that they are all configured for the AIR-ANT2460 (2.4GHz) and AIR-ANT5135D-R (5GHz) Antennas?

My question is, what are the effects toward the client if the wrong Antenna is selected in the configuration?  According to the configuration, if those antennas are selected, they are non-MIMO.  Is there a good way to test the effects of not having the correct Antenna configured?  I do have the Cisco Spectrum Expert.  I'm looking for ways to test for MIMO too if possible.

I'm also checking to see if MIMO functionality is related to software level.  I am planning to upgrade the environment to 6.x or 7.x in the future, but would like to know if MIMO is availabily on 4.2.  I do know that Client Link/ Beamforming does not look to be available on the 4.2 release.

I am also looking for a way to run a report that shows the Antennas configured per AP.  Right now I have WCS/WLC and have not found a way to do it.  If anyone does know, I would appreciate it.



I have this problem too.

If you are using 1250, then stay AWAY from 6.X and difinetly don't even touch 5.X.  Go to the 7.X.

Yeah I heard 5.x is not worth going too.  I'm thinking of upgrading straight to 7.x, otherwise I have to upgrade twice just to get to the 6.x Assurewave tested release.

If you are running " or later 4.2 release" then "You can upgrade directly to"

Just make sure you upgrade the boostrap while you are at it.
