cap3502e and number of antennas

Answered Question
Oct 31st, 2013
User Badges:

Hello!

Our customer needs to mount 3502e wap for 802.11g client devices only, thus he wants to buy 2.4GHz antennas - AIR-ANT2506.

So the questions are:

How many antennas he needs per AP?

Is the Clientlink technology supported with 2 antennas?

Is there benefit of using 3 AIR-ANT2506 for 802.11g?


Thanks for answers!

I would not use that if it was me to decide. Yes you can use it but then I would use all 3 ports. Your better off getting an omni with 6 leads. That way you have a single antenna per AP and you have 5ghz if later they want it.

Scott Fella, thx for answer.


AIR-ANT2440NV-R is an interesting solution, especially price


But I dont understand why you said, that its for 2.4ghz only?

I may be asking a stupid question, but what is the benefit of using one AIR-ANT2440NV-R antenna over 3 AIR-ANT2506?


At AP1310g it was 2 AIR-ANT2506 antennas (one - main, second - for diversity) so I understand this.


For what purpose the third AIR-ANT2506 antenna is used at 3502e?

Don't be stuck in the old ways. I too questioned it, but with all the feature these days, the antennas are more for ClientLink, spatial streams, etc. how I see it, why purchase a new AP if you plan on using it like an older generation AP. They will basically do the same thing. The newer antennas also have a better down tilt built in and having a single antenna is better since using separate antennas means you have to equally space the antennas properly. Use the recommended antennas for the access points and you will not be disappointed.

I agree.


However, I also don't recommend only getting a 2.4 Ghz antenna when you haven an AP with two radios.  Doesn't make sense.  You want to skimp on the cost of a dual-band antenna but your AP is dual band?


Look at the AIR-ANT2451NV-R instead.  Low profile, aesthetically pleasing to the eye and dual-band antenna in a single unit.

Thank you all for your answers.

I will try to apply AIR-ANT2440NV-R for this project.

Don't forget to disable your 802.11a/n radio.
