Wireless :: Which AP And Antenna To Use For Wireless Bridge (3 APs)
Jun 2, 2012
I would like some recommendations on which hardware to choose for my network. What I will need is 3 access points that can act as a wireless bridge between 3 buildings. I do not need (or want) clients to connect to the APs, so it is not a repeater i'm looking for.Currently i'm using 3 dlink dap-1353 for this, but there are several problems with this model, so I need to replace it.What I need is: 3 AP's that can act as a wireless bridge 2 Directional antennas I already have a omnidirectional antenna with RP-SMA connector for the main building, but it can be replaced with another omndidirectional antenna if needed.Some specific AP requirements: Wireless bridge Support ONE external antenna WPA or better security while in bridge mode 54Mbps or preferably better. A minimum stable connection of 3 Mb/s is required.Very important: The AP needs to work after a power outage, as they are common. This was the main problem with DAP-1353, as when they lost power the clock reset to 1970, and thus could not authenticate with the other AP's.
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.
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 looking for a router with an external antenna connection so I can attach an outside antenna to extend my wi-fi signal signal around my farm.Right now I have Hughes net internet service running to a Belkin 750 router, which is descent around the house, but has no connection for an external intenna.
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've just purchased an Genius ESR750H router which features two external and removable antennas. I know the range on this router is pretty decent but I'd like to find a set of antennas that would further increase the range for both the G and N wireless modes.
My question is how can I use this existing wi-fi as input to a router to make a sub wi-fi for four computers and a wireless printer. Some of my computers may need to be wired into the router.

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.
I have a customer using 1250 AP with monopole antenna, he face frequent disconnection for voice clients during roaming. Phone is forced for reregistration to call manager during the hand off. Same customer has dipole antenna in a different floor with 1250 AP and there is no issue observed for voice clients.
Is this an issue with monopole antenna ? Which is the best antenna to recommend for Cisco APs or wht is the occasion I need to use a dipole or monopole antenna ? How to understand the difference between them.
We have a campus with both office and industial areas with various propagation problems. Historically I have been installing and maintaining access points in the 1200 range, the latest being the 1242. All these have a similar antenna setup based on diversity pairs.Since Cisco seems to be dropping the old series any week now I have been looking at the 2602 as a replacement.I can find no good documentation on antenna selection and mounting suggestions for these.If I want a proper omni coverage pattern with dual band antennas, do I just set them to a H form assuming the unit is sitting on a wall?
The 3502e has 6 antenna connections, 3 for each band, 5GHz band is marked in blue. The antenna pigtails are only marked with the matching color - 3 blues or 3 blacks. No A,B or C. Does it matter which pigtail goes to which of the 3 terminals so long as the band is correct?
