1140 vs 1260 vs 3500

It seems that the only difference between the 1260 and the 3500 is the CleanAir capability. But what is the difference between the 1140 and the 1260? The only thing I can find is that the 1140 supports OfficeExtend.

wIs there any hardware differences at all between these three APs? Same chipset, same RF receivers, same performance in lab testing?

Thanks.

1140 vs 1260 vs 3500

Hi,

Here is the datsheets for all the 3 APs.. 1260 needs 12.4(25d)Ja1 as the minimum software but 1140 runs on old image as well!! 3500 does not come with the Autonomous mode of operation..

1140 does not come with a external antenna model.. where in 3500 have 2 variance internal and external antennas.. 1260 just with external antenna.

Thank you.

So what is the differnece between the 1260 and 1140 that requires them to use differnet software?

The 3500 has interal and external antenna options but I assume everthing else is virtually exactly the same between the internal and external models. But the 1260 and 1140 are different product lines to some degree becuase of the change in product number and different requirement in software so "something" is different.

Other than the CleanAir capibilities what are the technical difference beween the 1140 and 3500? Would they benchmark the same in a lab? Is the chipset different?

(I thought the 1260 was the internal antenna version to the 1250 which it is not so thanks for that).

The 1140 was released around 2009 while the 1260 was released 2010 so this is why the 1260 requires a newer software.  The main difference as to why you'd choose the 1260 over the 1140 is whether or not you want to use an external antenna.  The 1260 has a metal casing and it's designed to take a few knocks here and there.  Because the antenna is internal the 1140 is built around a hard-shelled plastic.  Mind you, both units are not waterproof.  The 1260 is meant to replace the 1250 (I think) but there's one major weakness of the 1260 (and the 3500i/e):  The 1260 (and the 3500i/e) support antennas that has a maximum gain of -6 dBm while the 1250 doesn't have one.  The 1250, optimally, requires 20.0 w of PoE power but the 1140, 3500 and 1260 is happy to chug along at 15.4 w PoE.

Yes the 1140 support OfficeExtend and the 1260 doesn't.

The only thing that makes the 3500 stand out among 1140 and 1260 is the CleanAir.

By the way, did hear about the new 3500p?  This AP answers the shortcoming of the -6 dBm gain antenna limitation.  This new AP, designed to be installed in stadiums, can support the new AIR-ANT25137NP.

"By the way, did hear about the new 3500p ?  This AP answers the shortcoming of the -6 dBm gain antenna limitation.  This new AP, designed to be installed in stadiums, can support the new AIR-ANT25137NP "

Thanks for the reply. Yes I was aware of the 3500p and the new antenna and am wondering why you would be limited to 6dBi on a 3500e but not on a "p". At first I just thought the "P" was for marketing to help emphasise the launch of the new 25137NP antenna, but yeah on the antenna sheet http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/at_a_glance_c45-513837.pdf it specifically says "p" model only.

So does anyone knows why a 3500E would be limited to 6dBi antennas but the 3500p could use 13dBi? The only things I can think of are:

1) The 3500p has automatic UL attenuation to help prevent possible UL RX saturation or overloading due to the extra gain. But this is a bit of a streatch and would only effect APs where the antenna would be very close to a client, and clients are all "low" output power devices.

2) It's a software issue in that the 3500e does not have a 10dBi antenna option in the settings to then allow it to limit the TX power to meet local regulations. Again, a strech becuase it would just be a software update required not a seperate HW product.

Thanks in advance.

Only Cisco wireless engineering department will know the answer.  I can hazzard a guess to say that they've never heard of anyone wanting anything higher than -6 dBm.  The "p" suffix, again I am only guessing here, is because Cisco engineering/marketing can't call it "improved" because the "i" is already being used.  Nor can it be called "enhanced" because "e" has been taken.  Therefore the next letter they can use is "high performance".

Again, a strech becuase it would just be a software update required not a seperate HW product.

Nope.  It's hardware controlled.

Just FYI, after speaking with a regional Cisco wireless engineer, there is absolutely no difference between a 3502e and a 3502p as far as the access point is concerned. You can use any antenna that you want with the 3502p, but Cisco TAC will not support that configuration. Unless you really have a need for the 3502p, stick with the 3502e, it will be cheaper. We just finished an outdoor deployment with 75 of them with terrawave omnidirectionals, works like a champ.
