1140 AP's internal antenna radiation pattern

Is it right or not?
1. Cisco Aironet 1040, 1140, 3500i Series Integrated Antennas Diagrams show Azimuth Plane Radiation Patterns and Elevation Plane Radiation Patterns when AP is mounted vertically on the wall (red LED above Cisco logo). So "Zero" on Azimuth Plane points to direction rectangular to AP's case plane (mounting wall plane), "Zero" on Elevation Plane points to ceiling and "180 degrees" points to floor?
2. Radio waves polarization in this case would be linear, in direction from ceiling to floor?
3. If AP would be mounted horizontally on the ceiling, then polarization would be in direction parallel to floor axis X and rectangular to floor axis Y? So induced signal on notebook integrated antenna, oriented rectangular to floor axis X, would be near zero?

Hi Valentine,
Here is Cisco Antenna Pattern Guide:
http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/prod_white_paper0900aecd806a1a3e.html
I had same problem on that, because the antenna pattern of 1130, 1140 and guides are not so clear.
From the guide you can see plate antenna forward direction which means Cisco logo direction ( if you place on wall it pointing horizintol, looking front) is Y, vertical Z, horizintol X(Left and right side), then if you see the 1130, 1140 antenna pattern. Azimuth is almost 360degrees which means doesn't matter Y and X (Ф), the problem Y and Z(Ө) , from the guide there mentioned most of the antenna Y(direction front) is 0degree, and some of them 90degree showed. So now if you trying to understand 1140 antenna Ө pattern, it would be no wave directing to front, you can see from 20-30degree till 90degree to tilting down side, and up side is like this, and pattern is 180degree waving to back side of antenna , which sounds crazy, so it is making complicated.
I have 1130, if you see 1130, from that point front radio pattern of that antenna tilting down side around 45degree(from 15-60) and also 180degree to backside .
I am confused and maybe what i think is true because on 1130 Elevation beamwidth is 50degree so it would be almost.
But other hand if Y front side is directing 270degree on the antenna pattern elveation there is no need worry we all, it is almost 180degree which means covering whole front of antenna Ө tangle.

Antenna Radiation Pattern Concern

We currently have a 1200 series with a AIR-ANT2506 covering a mid size area outdoors. We are looking to be able to connect to a new 1300 bridge that is slightly too far for the current antenna, we were considering replacing with a AIR-ANT24120 but the 7 degree vertical plane is concerning.
The antenna is mounted on rooftop and the concern is the signal may be weak on the ground do to the low vertical plane. Is this a valid concern, I'm still working through my understanding of radiation patterns.

Radiation pattern for 1140?

Hello!
I tried to find the radiation pattern for the 1140 AP, but no luck so far.
Anybody knows where to find it or can send me a copy?
Thanks
Mike

The radiating pattern of the 1140 should be the roughly the same with the 1130. Please refer to the following documents and scroll down to the 1130 for further information:

Radiation pattern for 1140 - need readable file

Hello,
I need a legible radiation pattern graph for the 1140 AP -- the antenna pattern
This is for a wireless deployment application which models signal strength.
It needs to be specific for the 1140 AP as the antenna has a Maximum gain of 3 dBi which is different than the antenna gain on the 1130 AP.
Can anyone help?
Thanks in advance
Some manufacturers will provide a file of the the antenna plot coordinates - that would ideally be what I need.

I found this file previously, but I can't read it. It seems like there should be an image of the antenna pattern that has better resolution than this. The application I use requires that 360 numbers be entered for the E-plane and 360 numbers for the H-plane.
So a file of the antenna plot coordinates would really be what I need. Does cisco provide these?
Thanks....

1300 Series w/ Internal Antenna

We have installed several external antenna 1300's but this is the first with an internal antenna. Which direction is the wireless radiating? The mount that we have places the front (grey side) against a wall with the rear facing outward. Thanks.

Hi Michael,
You probably want to reverse this mounting, the radiation patterns for the 1300 are shown (at the very end of this doc)

AP mounting options versus internal antennas

Hi All,
I have previously used the 1232s and 1242s with external antennas so I could wall mount them (ceiling mounted hardware is not always an option) and have the antennas oriented correctly. I'm now looking at the newer APs with 802.11n some of which have internal antennas and are more cost effective, e.g. the 1040. The 1040 has internal antennas but it is apparently wall mountable - from http://www.cisco.com/en/US/docs/wireless/access_point/1260/quick/guide/ap1260getstart.html#wp42683
"Cisco Aironet 3500, 1260, 1140, 1130, and 1040 series access points can be mounted in several configurations, including on a suspended ceiling, on a hard ceiling or wall, on an elecrtical or network box, and above a suspended ceiling. Click this URL to browse to complete access point mounting instructions: http://www.cisco.com/en/US/docs/wireless/access_point/mounting/guide/apmount.html "
How does wall mounting an AP with internal antennas affect the coverage? Surely the antennas will be oriented the wrong way to provide the correct coverage pattern. Or are the antennas able to provide the same coverage no matter what way up they are?
Many Thanks,
Scott

Hey Scott,
The 1040, like the 1140 can be mounted on the wall. The horizontal and vertical footprint is almost similar. Like a ball. So it won't make any severe difference at all.

EIRP for Internal Antenna APs

Hello everyone
I understand EIRP for external Antenna APs but does the transmit power of internal APs will be considered as EIRP or we will add antenna gain to get it? For Example 1131 and 1142 have different antenna gais so keeping tranmit power same 25mw will have same EIRP ro diffe

It's exactly the same with internal antenna.
The difference of antennas is not big enough to actually matter on EIRP here.
Let me explain.
The AP will adapt the transmit power by steps of 3db of gain of the antenna.
Example : the AP transmits at 17dbm and you have a 3dbi gain antenna, the EIRP is 20.
If you increase the antenna gain to 4, nothing will change. Only when arrived at 6dbi, the AP will lower the transmit power to 14dbm to stay at EIRP 20.
So it's not granular enough to matter if the 1130 has a 3dbi antenna and the 1140 a 4dbi :-)

Radiation Pattern of WAP561

Hi all
After replacing a AIR-AP1231G and a WAP200 (which both had external antennae) with cluster of two WAP561, I noticed that Wifi Analyzer (https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer) on my android phones shows lower values than before.
Wifi is usable and performance is acceptable when near the AP, but there's some potential for optimization. Less than 10m away and through 2 wooden doors (almost straight line-of-sight to the AP), signal strength drops well beneath -70dBm.
I do have the possibility to move the APs around and mount them flat, upside-down or vertical in different places. However, I'd like to base the optimisation on well-informed guess instead of sheer trial-and error.
I've been trying to find a radiation pattern diagram for the WAP561 (relative to it's shape), like there is for other Cisco Wireless antennae (http://www.cisco.com/en/US/partner/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html) or APs with built-in antennae (http://www.cisco.com/en/US/partner/docs/wireless/technology/apdeploy/7.5/Cisco_Aironet75.html#wp44985), so I could determine the best position and orientation for the APs.
Neither Admin Guide nor Quick Start Manual have a word to say about the characteristics of the internal antennae of the WAP561, the mounting instructions just say that the device can be mounted horizontally or vertically.
Is there another document or reference guide I could consult?
Thanks a lot for your thoughts, comments or pointers.
Marc

In the meantime, I assumed that the pattern would have to be roughly the same as for the 1600i/2600i/3600i as described in
http://www.cisco.com/en/US/partner/docs/wireless/technology/apdeploy/7.5/Cisco_Aironet75.html#wp44985 (Fig 40-44).
After rearranging the APs accordingly (in extenso: ceiling-mounted), wireless coverage across the whole flat has improved. I did not perform a full site survey, but the improvement is obvious, less for the laptops, but more so for the smartphones in areas where WLAN was practically unusable before.
cheers

Broken internal antenna!

Hi all! First time I post here :P
It's like this. I broke my internal antenna on my PowerBook G4 12" when I was going to check which airport card I had. I'm kind of.. violence of myself but anyway. I was going to check which card I had and the antenna.. Popped of the card. Or atleast I think it is the antenna.
Well, it broke and now I CAN still found the card, but no connections (:P). Am I able to reconnect the cable in some way? Because there is some metallic thing sticking out from the card and the cable is.. Loose, and it's now harder to shut that little door to the card. Well.. I think that's all I can say for now.
Here's two pic's of the thing ^_^ (Photo's taken with my mobile)
Thanks for now! I hope you are able to help me!
I can take pic's with my real digital camera if anyone wants better quality.
PowerBook G4 12" Mac OS X (10.4.7)

Welcome to the discussions
You have one of 2 choices you can either take it to an Apple store or contact Applecare, if you have it.
Or if you want to attempt it, look at the link and you will see you can unplug the connecter to the card and twist the cable and insert it and either crimp it or solder it and then re attach it.

An AP500 with internal antennas?

Is there any chance that an AP500 might be developed with internal antennas?
I have at least one deployment where the AP541N might have been seriously considered, except for its external antennas, which for that site are too vulnerable... of being moved, tampered, etc.
So in that case the AP1142 with its internal antennas and smaller footprint, is a better fit. But the 1142 is a lot more expensive, doesn't do clustering, etc.
If a new model of AP500 were developed to fit into the casing of an AP1140 that would be, for some customers, quite an enticing product!
But I'm not holding my breath... it seems Cisco made a decision to use only external antennas with these.

Rich,
Thank you for your feedback, its great to hear from end-users about how we can make our product lines fit your needs better. These boards are HIGHLY visible to Cisco. Therefore, I'm sure your concerns will be heard and addressed accordingly.

Best direction for internal antenna on 1602i

Can anyone suggest best direction for internal antenna on 1602i when placed on a wall, as i am aware that best location for these AP's is to be placed on ceilings with antenna direction at 90 for best results.
I have done this with the majority of AP's but some need to be mounted on walls, so looking for some info on antenna direction for best results in coverage.
Thanks

Hello, tavery.
Check table 5, 6, and 7 on this link for several antenna options for a 1600 AP. Will you be needing an Omnidirectional antenna for your application?

8600 luna internal antenna strength

I have the above phone on the orange metwork and find it very difficult to get a signal downstairs in my house even though Orange network says i am in a good coverage area.
I do not have lead lined rooms or a big house and signal strength outside of the house is good, a friend has an old sony phone which has a good signal is ther a Nokia make that has a good internal antenna . i like the 6500 Classic :-)

I always found my Luna to give good signal !
My 8800 arte hangs onto signal in the most fringe areas.
