IAP 175 and Ant-90

Hello's

 

I'm looking to deploy IAP-175's with the Ant-90 antenna. Given that the 175 has 4 antenna's should I plan for "2" Ant-90 antenna's for every IAP-175 ?

 

thanks

Re: IAP 175 and Ant-90

It depends on how you are deploying your coverage.  The AP-ANT-90 is a downtilt omnidirectional antenna, so that means it is suitable for mounting 30 to 40 feet above in a warehouse where you need coverage on the floor.  It has two connectors, so you would only need a single AP-ANT-90 antenna for each band.  So if you only want 2.4ghz coverage, you will only need one AP-ANT-90 antenna.  If you want both 2.4ghz and 5ghz coverage, you will need two AP-ANT-90 antennas.  That is IF that is the antenna you need for that application...

Just to be extra clear....Colin is not saying that you can use one (1) ANT-90 and connect a pigtail to each radio  (leaving the other chain unconnected).

 

MIMO radios must have all chains connected.   So if you want dual band coverage, you need two (2) ANT-90s.

 

Also, ANT-90 is perfectly good higher than 30-40ft (10-15m).   In fact, the antenna was originally developed for seaport high mast lighting systems.  We have them deployed as high as 50 meters and they work great.

Re: IAP 175 and Ant-90

Thanks for your responses. I guess I was mistaken and maybe more confused after both posts. I apologize if the next few questions are dumb.

 

From the Spec sheet, I understand that the antenna is a dual band antenna.   To quote the sheet  ".....The Aruba AP-ANT-90 is a dual-band, spatial diversity....." . Am I misunderstanding this? And if it is dual band and only has two connectors in different bands and MIMO radios must have all chains connected does this not also imply that I require two Ant-90's? I must be overthinking this or simply not getting it. Please advise.

 

Also, what If i do not desire dual band coverage? What If i only want 2.4Ghz? The implementation is a warehouse, 50ft tall hence  the question.

 

thanks again for your time and expertise,

Blue,

 

Both connectors are dual band.

Re: IAP 175 and Ant-90

Thanks cl

So could I get one AP ant-90 and connect to Radio 0 and Radio 1? And does this not violate the "not all chains are connected?"

 

thanks,

Re: IAP 175 and Ant-90

no.   

 

you need 2 ANT-90s.

 

connect both pigtails on one to the 2.4GHz radio.

 

connect both pigtails on the other to the 5GHz radio.
