AP-1131AG radiation pattern

Hi All
How should I mount an AP-1131AG for the best coverage area? vertical(wall) , Horizontal(ceiling).
Thank you.

The 1131AG AP is meant to hang horizontally on the ceiling. The radiation pattern is an omnidirectional "donut", which extends out from the LED ring in the center.

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.

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.

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....

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

3502i radiation pattern data points

Is there any way to find out the exact 360° data points for the 3502i internal antennas? The patterns are found on page 69 of:
http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.pdf
but I need the specific data points to be able to enter it in my modeling software.
Thanks!

Best mounting location for a 1131AG AP with intergrated antenna

Hi Guys.
Im deciding on the best mounting location and height to mount a aironet 1131AG Access point with intergrated antenna. Can anyone tell me the beam spread/angle that comes from these access points ?
thanks.

Hi Jason,
Just to add a note to the good info from Andrew. The Radiation pattern for the 1131 is shown nicely in the doc (towards the very end);

I want to hide my time capsule so a burglar cannot find it (we were broken into last week and our imac taken).

So, I would like to keep it separate from my BT wireless router. Is this stupid? Will my wireless connection be weaker as a result?
I would like my BT router to sit in the downstairs study with my macbook and replacement imac connecting wirelessly to it. Then I would like my time capsule to be hidden away elsewhere out of sight in the event of another break in. It seems silly connecting it to the router so that a thief could easily swipe it if they try to come in again - and then my backups are gone. But on the other hand, don't apple recommend that the time capsule is your main wireless hub rather than simply annexing it to your existing network?
Will the backups be much slower if the time capsule is stored elsewhere?
Will I be unable to connect my printer to the wireless network?
Thanks, all advice appreciated

Interesting post.. first of its kind I have read.

Not stupid in the circumstances.. i hope you had contents insurance and got it replaced and had backups of your files.
You cannot wireless link the TC to the BT router.. you can ethernet connect them.. or use ethernet replacement like EOP adapters.

You can use it in bridge as a wireless access point plus hard disk. That will not affect the network.
Backup speed will depend on the wireless connection to your BT router.. that will be the issue. Unless you do some tricky stuff and use a secondary wireless client in the computer.. a usb stick could be plenty for the internet access but stick with TC for local lan.. but this might be getting too complicated.
Is the printer a wireless network printer or needs to be usb connected?
If the printer is wireless type then no issues.. but even that can be worked around.
The TC doesn't have wall mount holes, unlike the old discus version.. which was very neat.. On the other hand you can remove the rubber mat easily with a hot air gun and easily remove the bottom aluminium cover so to add wall or ceiling mount holes.. ceiling mount is excellent as a thief will probably never look there. or find it too hard to reach and if you screw it down well.. which you have to as it weighs a bit, then the rf radiation pattern is near ideal. Stupid apple for removing design features from one model (eg POE as well) in the old model for aesthetics only design.

Snow Airport and G5 Losing contact.

The have been working well. No big changes in environment. But the G5 can't see the Airport Base Station v4.0.9 unless I haul the G5 out of the closet and put it on a table.
tried cleaning off the airport card contacts in the G5.
The airport seems to work fine with my laptop.
Anyone with similar experiences and solutions? External antenna for the G5? Which one?
The Snow Airport is mounted on a wall with the sockets pointed up. Does anyone know the radiation pattern? Would orienting it differently solve the problem?
Thanks,
Ty Ford

Have a 2 GHz DP G5 equipped with an Airport Extreme wireless card (802.11b/g) and a stubby airport antenna hanging out the back -- used to have signal strength issues with older snow base station (802.11b only), as well as complete drop outs, causing my cable modem connection to disappear for 30 seconds at a time, every now and again. Even tried an external antenna on the old snow base station unit -- did not help much.
Bought an Airport Extreme base station, and signal strength on DP G5 stays strong and no more dropping of cable modem connection. Don't need an external antenna for Airport Extreme base station, either -- internal antenna works fine.
I have the DP G5 in the basement -- Airport Extreme is one floor up (in the same location where older snow airport base unit used to sit), and over to the other side of the house from the G5 location -- 50-60 ft distance.
Your solution may be to upgrade your wireless base station unit.

Deploying internal and external wireless users

what i have npw AP1232AG, WLSM and SUP720. i,ve implemented wlan for our internal users, via fast secure roaming. Now i want to setup the connection for external users. i have a seperate internet connection for external users
. what is the best method to deploy wireless for external users?

Best from the perspective of antennas and radiation patterns, or best from the perspective of integrating the indoor / outdoor systems?
Or "external" meaning guests?
Please clarify the question ...

RF Predictions in WCS

So I am adding access points to WCS 6.0 and I am using a specialty antenna. When I choose other for the antenna type and I enter the dbi of the antenna when I hit save to place the APs it tells me it cannot give em the rf prediction for those APs. How do I get around this other than selecting a cisco antenna?

Azimuth and Elevation) for the antenna needs to be known not just the power.
Therefore, as WCS doesn’t have the detail for the antenna you’re using it can’t perform the prediction, this is a limitation of WCS but it guarantees the accuracy of the coverage prediction.
It also enforces the point of buying Cisco antennas!

WCS AP Setting - Antenna Mode - What does it do?

Hello,
I'm working configuring our wireless networking. When setting up AP templates in WCS I came across a setting that I'm not sure of and haven't been able to find anything about.
What is Antenna Mode and what does it do? There are three options that I've seen..
Sector A
Sector B
OMNI (Sector A and Sector B)
Does anyone know what these settings do?
Thank You!
Eric

Sector A = "Front"
Sector B = "Rear"
Omni = Front + Rear radiation pattern
Good Luck
