I am using two Cisco Aironet 1252 (cisco AIR-AP1252AG-A-K9) to setup a point to point link (one is configured as root bridge and is as a non-root bridge). Both Aironets are running software version Version 12.4(25d)JA.
Is there a way that I can that I can perform an antenna alignment test on the Aironet that is configured as a non-root bridge?executing the following command dot11 dot11radio 0 ? does not show the antenna-alignemnet option.
as per reading documentation, i only see the dual-band antenna option for this device. i am planning to use this for mulch-site bridging. can i substitute the dual-band antenna with a single-band high gain antenna for such deployment?
Looking at the WSSI datasheet it mentions internal antenna- unlcealr if this is just with 3602i or 3602e as well.We plan to deploy 3602e in enclusures- hence the external antenna- so the WSSI would be shielded.
Does the WSSI only use it's own internal antenna or is there any option to use external?
I have a Cisco Aironet 1242G and an outdoor omni 12 dbi antenna. I hooked it all up to day (antenna is connected with a 100ft cable). My signal is very disappointing. I have it behind a garage and can only get about maybe 75 foot away and the signal gets very weak.
Is there something that needs to be configured in the aironet? I have enabled external antenna and played with the settings. Is the 12 dbi antenna just too much?
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?
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.
I have a few 1142N Aironets with internal antennas in place, and I am not thrilled by its coverage. I want to extend my wireless network because of a new building which led me to the following question;Is there is any difference in wireless coverage when using external dipole antenna’s (the small ones, for example the AIR-ANT2524 for a new 2600 Aironet) versus the internal (dipole) antenna’s. I am aware you have more options when using external antenna’s, such as omni, directional, outdoor etc.
For an indoor office or warehouse deployment, where temperature is not a concern, why would I buy for example the 2600E with 4 dipole antenna’s over the 2600i?I have read most Aironet datasheets and their antenna options, but can’t find a word about the advantages of external dipole antennas. I would expect external antennas would give better coverage.. is this true?
I have a problem where clients cannot roam between Cisco 1231g-e-k9 and recently installed cisco 1242g-e-k9 access points.. On looking at the CDP option on the 1231 and 1242 access points they are all aware of each other. However if I use the Network View option I see a different picture. All the 1231 access points can see each other but not see the 1242's. Network View on the1242 shows all the 1231's but none of the 1242's. The 1231 are running ver. 12.3(8)JEB and the 1242's are running ver. 12.4(21a)JA1.
I've got a network of several AIR-LAP-1242G LWAPP access points controlled by a 2112 WLC. I assign static IP addresses to each LWAPP, but every few weeks, a couple of them (at random) revert back to grabbing a DHCP-assigned dynamic address for themselves, despite the fact that they're supposedly solidy configured to have static IPs. What's going on here? Is this a bug in their firmware or the WLC's firmware? If I reboot the APs, then they come up with their static IPs, but after running some random number of days/weeks, will spontaneously change their own management IP addresses and grab a DHCP address for themselves.
The 1242G APs version numbers reported by the WLC's web GUI are:
I need to update from older Cisco 350 Aironet 802.11a/b Wireless CardBus Adapters to Cisco cb21ag Aironet 802.11a/b/g Wireless CardBus Adapters in rugged tablet pc's. I need these without the antenna cap present to utilize the tablets antenna sytem. They are pictured on the Cisco website but Cisco partners I've contacted have been unable to assist me in purchasing them.
I have a AIR-LAP1242G-A-K9. I have several question:
1. Does the antenna is a MUST for it to work. 2. If I have a 1 unit of AIR-ANT2422DG-R (antenna) , does the wireless access still work? Do I need 2 antenna 3. If I have a 1 unit of AIR-ANT2422DG-R, does 802.11 b supported.
I connected an external 12dBi omni-directional antenna for Networks 2.4 Ghz (TL-ANT2412D) with LMR-400 cable 5M but my antenna "emits" nothing, I have no signal. With the two supplied antennas with WAP200 I signal but does not cover any desired area.
We are installing 1260 Access Point (AIR-LAP1262N-E-K9) with 2 sets of external antenna:AIR-ANT2460NP-R (2.4Ghz, Patch Wall-mount, 6dBi Directional) & AIR-ANT5160NP-R (5Ghz, Patch Wall-mount, 6dBi Directional).What would be the recommended separation of the 2 antennas if they will be mounted beside each other?
I recently checked the output of one of my AP 3502AGN which are connected to a WiSM with the current 7.0.240.0 software. There I saw the following output:
show ap config 802.11b 3502AGN-1100c-1 Legacy Tx Beamforming ..................... ENABLED Antenna Type............................... INTERNAL_ANTENNA
All antennas have to be in the same direction on the AP and I guess when the old 1230 is working well the 1262 will be only better . Attached u see how I plan to mount the new AP versus the old one...
When we take a look at the internal antennas on the 1142 AP, we notice the 5ghz pointed all the same way, but for the 2.4ghz we can see each offset by 45/120 degrees. It was my understanding that all antennas are omnidirectionals on the 1142, why are those 2.4ghz antennas not all pointed the same way? onfiguration advantage and that each antenna is indeed omnicadirectional? Example, if I shut just one antenna off, do I lose a sector (120degree)?
i want to install a 3500e. I have a hole in my wireless network where this AP will be a perfect fit. I do have a wireless controller running code 6.x, so I think I will need to upgrade to 7 which is not a big deal.
The problem I have is the antenna selection. Since the AP has MIMO multiple-inputs multiple-inputs I’m perplexed on the type of antenna to choose. Since the environment is a warehouse the Omni directional would be preferred - should I also add the dipole antenna for close proximity to the AP. Also, I noticed in the getting started guide the 3500e has 6 external connection points 3 for 2.4 and 3 for 5 GHz. The antenna documentation says to use dual-band antennas, but this contradicts what is shown in the getting started guide. So what antennas should I get to make the 3500e work in a warehouse environment.
I am still new to wireless. I have been studing for my CCNA Wireless for about 6 months now so I still have a lot of questions.
Right now I have to deploy some new APs. We are using 3502e APs. I have a qustion on how to mount antennas for these access points. I have to make a mounting bracket the new installations. What was done with the previous APs was to mount a unistrut beam to an I beam in the building. There is 2 AIR-ANT-1728's and 2 AIR-ANT-5160V-R antennas mounted straight out on the unistrut. Then they put a T bracket on the unistrut and mounted a second bar 90 degrees from the main bar and connected the third 1728 and 5160 antennas on the second mounting bracket. So we have 4 antennas in a row, and two off to the side 90 degrees from the other 4 antennas.
My question, is this OK to have them this way, or would it be better to have all 6 antennas in a straight line when I fabricate my new AP brackets?
Here is a picture of what I am talking about. This would be looking at it from above. Current New Proposal __________o__o__o__o_ _________o__o__o__o__o__o | AP AP | |o | |o
The 3502e has 3 antenna terminals for each band. Is the order of connection to the antenna pigtails significant? The antenna pigtails are not marked ABC (just blue boots for 5GHz.)
I have a DWA-547 wireless adapter in my PC and only get 1 to 2 bars....I was thinking about getting another wireless adapter or getting wireless antennas to boost the signal if it works?

I'm going to install a Cisco Aironet 1310g (ap mode) with external antenna in a warehouse (contain many metal surfaces), and I need to install this antennas on ceiling (distance from floor to ceiling is about 13 metres). I need to get at least 1Mbps performance. AP clients are Motorola MC9190-G mobile computers.
mounting for the above antenna types. see figures below.
The figures above, are the antenna mounting correct? For figure 1, can the two antennas be separated by 4" or more? For figure 2, the two antennas will be side by side.
We have 3 3602Es connected to a 2504 WLC. I was wondering for best practices for antenna placement. They are all mounted on the side of a wall, near the ceiling (above everyone's head).
When using dipole antennas such as AIR-ANT 4941 with the 2.4 Ghz 1250 AP, must the antennas be spaced EXACTLY as far apart as the antenna connectors on the AP, or can the dipoles be spread further out, say to 4" spacing.
Currently have access points located throughout our warehouse that use the AIR ANT5160V-R antenna's from Cisco. These AP's are 25' in the air. However we have a lot of voice quality issues off of the 5Ghz band, we do no other services on this band as we keep data on the 2.4Ghz.This was all installed by a vendor but from what I am seeing on the documentation [URL] the cover is extremely poor for these antennas despite AP's everywhere. They cover side to side but aren't a well rounded AP at all.it seems like the AIR-ANT5145V-R would be better suited even though this is a warehouse.
I have a small building which has two levels. I have a 1230 on the top floor and about 10 people. Below that floor is another office with 10 people. They don't all use wireless, infact its only used for guests and smartphones, tablets of which there aren't many.I was wondering instead of sticking another unit in the downstairs office, Can I either use two anntenna's, one on each floor connected to the one controller or is there a good antenna which will do both floors?The floor is concrete, I have one antenna attached to the right hand connector of the 1230 and can get 2 or 3 bars in the lower office. Thou as its a flat antenna this doesn't cover the part of the office directly beneath it.
