3502i radiation pattern

I am trying to locate the radiation pattern for a 3502 with an internal antenna. We have some high ceilings so the elevation pattern could impact our placement strategy.

Thanks

Go to this website:

http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html

When the page completes loading go to the bottom of the page until you reach the 1130 and the 1140.  The 3500 will share the same "signature" as the 1130 and the 1140.  Due to the design, the signal distributes closely like a ball and you can mount the 3500i either from the roof or flat from a wall.

Please don't forget to rate our useful posts.  Thanks.

The 1130 has a elevation Beamwidth of 50 degrees compared to 120 for the 1140. That is night and day for placement planing. Any ideas on where to find the actual pattern for the 3502 with the built in antennas?

tan 60 X ceiling height = Radius of floor coverage above 3db

tan 25 X ceiling height = Radius of floor coverage above 3db

For a 16 ft ceiling= ~28ft radius  for the 1140 vs ~7.

I'd like to second this request for 3502i radiation pattern info.  Anyone?


is this what you are looking for?

Integrated Antenna

• 2.4 GHz, Gain 4 dBi, internal Omni, horizontal beamwidth 360°

• 5 GHz, Gain 3 dBi, internal Omni, horizontal beamwidth 360°

No, this is what I'm looking for, but for the 3502i:

From the

Cisco Aironet Antennas and Accessories Reference Guide

http://www.cisco.com/en/US/customer/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html

I think the doc you reference may have since been updated as the plot you shared for the 1140 is now mentioned as being for the 'Cisco Aironet 1040, 1140, 3500i Series Integrated Antennas'.
