AP-ANT-35A Split Across Two Radios on IAP-228-US

Hello Airheads,

 

I have a customer that is trying to provide coverage to a freezer in a warehouse as well as a small portion of the warehouse floor itself. He's not trying to cover a lot of area/sqft, but he is trying to accomplish this with a single AP (IAP-228-US) and two antennas.

 

Now, he doesn't want to have to do 2.4Ghz in one area (say, the freezer) and 5Ghz in the other area (the warehouse floor)... instead, he hopes to use two AP-ANT-35A antennas BUT NOT connect them each to a SINGLE radio... instead, he wants to connect each AP-ANT-35A to BOTH radios - then, place one AP-ANT-35A in the freezer and one on the warehouse floor.

 

So, AP-ANT-35A #1 would have one antenna cable connected to the 2.4Ghz radio and another to the 5Ghz radio - the third pigtail would remain unused. 


Then. AP-ANT-35A #2 would have one antenna cable connected to the 2.4Ghz radio and another to the 5Ghz radio - again, the third pigtail would remain unused. 

 

Hope this makes sense.

I know this is a poor design choice, but will it work?

And, if so, what issues may he expect?

Ultimately, I hope to have him purchase a second access point, but he's in a pinch due to budget. 


Thanks in advance!

This won't work, or at least is a really bad idea.

You should not have signal pointing in different directions like that.  In the very least you will get 'hidden node' issues.  There will be many other issues due to the mimo nature of the radios.

 

It would be much better to have separate APs covering each area.  If the warehouse area is normal temperature, then you could possibly mount the AP for the freezer there, and then put the antenna inside the freezer.  If it has to be a 3x3:3 radio specs, then 2 x AP214 and 2 x AP-ANT-35A should do it.  Otherwise, you could use 2 x AP204 and 2 x AP-ANT-25A if 2x2:2 radios are ok.

 

Either way, it is much better to spend a little more and get it right the first time.
