Cisco Aironet 1552S Directional Antennas

Hi,
Have a project were there is a length of straight road about 800 meters long.
The 1552S comes with omnidirectional aerials and would like to know if directional aerials can be fitted to maximise range.
Regards
Darryl

Hi Amit,
The last one looks ok. Notice it has three connections so will have to have a closer look at this and see if there are any issues connecting to the 1552S.

  • CISCO aironet 1310 integrated antenna poor range

    Hi
    I am in Canada
    I am trying to configure an AIRONET 1310 with INTEGRATED antenna
    to work as an access point for clients on a campground
    The range I get is awfull (50 feet and I loose the signal completly)
    the aironet is outside and no tree are blocking it.
    I configured it all by default exept :
    -- in network interfaces : Radio0-802.11G Setting
    -- I changed DATA RATES from Default to Best Range

    Hi,
    1300 Integrated antenna model comes with a Vertically polarized 13dBi gain antenna. The beam width is 36° E-plane by 38° H-plane.
    Following is the range -
    Americas
    • 865 feet (260 meters) at 54 Mbps
    • 3465 feet (1055 meters) at 11 Mbps
    ETSI
    • 150 feet (45 meters) at 54 Mbps
    • 775 feet (235 meters) at 11 Mbps
    TELEC
    • 485 feet (145 meters) at 54 Mbps
    • 1095 feet (330 meters) at 11 Mbps
    So the range what you are getting is way too low.
    Please check the orientation of the AP, the antenna is Vertically Polarized.
    So the AP should be mounted vertically.
    Second make a note at the beamwidth 36° E-plane by 38° H-plane. Make sure that all your clients are only in this coverage area. If its an open area and you want coverage for client overall the area probably I won't go with this AP being a sector antenna not providing coverage in all 360° H-Plane.

  • Aironet 1552E with 8-dBi Directional Antenna AIR-ANT2588P3M-N

    Hello everyone,
    Im building a local wireless network and im going to use the Aironet 1552E outdoor cisco access point, with 2 patch-directional Antenna 8dBi (AIR-ANT2588P3M-N) at 2,4 GHz.
    The problem im facing is that i have to cover a specific area with really thick walls (about 80cm cement and stone made). That obviously decreases my signal a lot. (i currently use an indoor cisco aironet 1130 (2dBi) and its really hard for it to have more than 3-4 signal bars inside the room).
    So i would like to know, how can i calculate the distance that the new access point with the patch antenna's going to cover?
    Or where can i find any specifications about the stength of the signal and the coverage area in real enviroment?
    Thanks in advance for your answers and comments,
    Periklis

    Dear Scott,
    I understand what you say, so to make it easier for you to provide me with a “possible” answer, I will inform you about the situation. And I hope that you will be able to help me.
    We have already placed a local wireless network using the 1130AG cisco Access points. That Cisco as you know has a 2dBi omnidirectional internal antenna.  We placed them outside of the buildings, inside of electrological boxes to protect them from the environmental changes.  The walls that the signal has to penetrate are about 80cm of cement and stone. (pretty thick walls…)
    Still, their signal differs (for ipad’s and smartphones) to 2-1  and laptops 4-5. Pretty good for an indoor AP placed outside of the buildings!
    In order to increase our signal to the maximum that we can, we decided to change the 1130AG’s with 1532 E or 1552 E  AP’s.  And combine them with the 2,4GHz external 8dBi directional PATCH antennas.
    After thinking about a way to provide better signal of wireless to our customers, we decided that  increasing the signals power from 2dBi to 8dBi as well as changing the antenna’s from omnidirectional to patch directional , we will be able to achieve better penetration of the signal inside the buildings.
    What im questioning you is, IF that thought of ours has a logic and that IF is gonna work with the current situation.
    Also, I would like to know since we will propably go for this method, in which high and distance from the 1st building it should be for better coverage?
    Hope to hear from you soon, since I really need an expert’s help on this task.
    Thank you

  • Linksys WRT54G with Cisco Aironet antennas

    Hi Cisco users,
    I've got a small project:
    I need to provide a wireless network from a farmhous to a piggery:
    Distance about 40 metres, no obstructions
    Equipment:     Linksys WRT54G v3.1
    When i place the wrt54g to the most far point of the house (towards the piggery) i get a fairly stable signal of around 11Mbps
    I want to strengthen the signal via an external antenna, preferrably outdoor.
    i'm thinking of this antenna:
    Cisco Aironet 8.5-dBi Patch Antenna (AIR-ANT2485P-R)
    http://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2485.html
    or the same one as above only with 6 dBi.
    http://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2460.html
    Both the linksys and cisco aironet antenna's has RP-TNC connectors.
    My questions:
    1: Can cisco aironet antenna's work with a linksys wrt54G, based on the same connectors.
    2: Is the antenna strong enough? can i cover a distance of 40/50 meters with this antenna, or with the 6dBi version?
    3: it's a directional antenna. the piggery is straigh ahead of the farm house. How much beam width do i have on the end of the signal for coverage?
    4: maybe i need an extension cable. is this the right one?
    Cisco Aironet 5-ft, low-loss, 2.4-GHz RF cable with RP-TNC connectors (AIR-CAB005LL-R)
    http://www.comegacity.com/networking-wireless-b-bn/antennas-cables/cisco-air-cab005ll-r-aironet-5-low-loss-cable
    Thanks in advance.

    The connector has to be the same but also the impedance. Cisco APs are at 50 ohms. Not sure about linksys ...
    Otherwise if you put the antenna outdoor and there is no obstacle, 40/50m should be reached with those antennas. Take the lowest length of cable possible to put the antenna outdoor though as cable brings loss.
    I can't comment about if the 6dbi will be enough as this would require experience with the same hardware which I don't have.
    My 2 cents

  • Turning on cisco aironet bridge without any antenna

    I'm going to test two cisco aironet brigde with 21dB solid dish antenna to connect two buildings.
    But, as first test, I want to config everything in the office, without mounting antennas.
    Is it possible to turn on the bridge without antenna or this would damage it?

    According to Cisco documentation, you should not power up an access point without it being connected to an antenna, so as to not burn the antenna leads inside the AP. Other documentation suggests that if you are going to power an AP without an antenna being connected, the AP should be broadcasting its signal at no more than 5 mW. This is supposedly not enough power to burn the leads.
    It will not hurt the AP to be powered up for the configuration and testing phase. I would not allow it to run for more than one hour without antenna's connected though. I have configured over 800 AP's in the last year and 95% were not connected to antenna's during configuration.
    Also, you may want to consult Cisco's site for the wattage setting with using the 21 dBi dish. I think the max is 20 mW when using the dish, based on the 1W max specified by the FCC.
    Good Luck, I hope this helps.

  • Cisco Aironet 1300 series

    Hello,
    i have 2 cisco aironet 1300 series configured as root bridge and non root bridge, i managed to configure them and they are associating only when they adjacent , when i separate them them communication fail , could you please help me to solve this . thx 

    Those are very old bridges. So if they are still functioning okay, do they require external antennas or not and do you have external antennas if they do?

  • Configuration of a Point to MultiPoint link with Cisco Aironet 1310 bridges

    Hi All,
    The previous problem of which I started another conversation here:
    http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=General&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddba023
    somehow dissapeared. It could have been a problem of interferences.
    I have another issue with other (multipoint) wireless WAN link, which I hope has a solution.
    On the central node, we have an Cisco Aironet 1310 bridge configured as root-bridge. It has a panel of four vertical polarity 17 dBi panel 90? antennas, with more than enough gain (there is a 250 mWatts 802.11 b/g amplifier, before the 4-way splitter) and excellent line of sight to three remote bridges.
    The three (03) remote bridges are also Aironet 1310 models, confidured as non-root-bridges.
    The problem we have is that it seems that when the three remote links operate concurrently the amount of lost packets is huge. When I shutdown the radio interfaces of two bridges, the remaining bridge makes an excellent link with the central node.
    It seems that some hours are more critical than others, also the links operate much worse when there is some (small) network traffic in them.
    I have read the 1310 manuals, and I can't find a sample configuration for point to multi-point links.
    Does someone knows what radio interface configuration should I need to use to establish better quality communication?
    I mean, perhaps the 1 x root - 3 x no root configuration is not recommendable for the multipoint link configuration.
    Any hints will be welcome.
    Best Regards,
    Igor Sotelo.

    Hi All,
    Thank you for the information. I configured the distance on the root bridges, but the links showed instability.
    I'm using a bi-directional amplifier. It has two pieces. According to the manuals, one is installed indoors, the other outdoors. I'm not sure if the indoors piece has the transmition module or it's only the injector.
    We could establish connection at 7 km (around 4 milles) distance from the central point, using 24 dBi antennas on the other side.
    However, we have issues with a near located point that is only 1.2 Km (around 0.8 milles) away and has a 13 dBi integrated patch antenna. The signal strenght value we get there is in the -62 to -68 dBm range, and is noticiably (5-10 dBm) lower than the strenght we get at other points of the link. And I have trouble establishing a high quality link with that point, using OFDM modulation. I tend to think that if I remove the amplifier I'm not going to reach that point at all. The EIRP on the central iste is 34 dBm / 2.5 watts, without amplifier it would be 26 dBm / 0.4 watts.
    On the opposite sites the EIRP is 33 dBm / 2 watts using CCK or 28 dBm / 0.63 watts using OFDM.
    When one looks at the central site from that point, an Motorola Canopy with passive reflector (EIRP 48 dBm or around 64 watts) can be seen. It doesn't have the same direction, but the opposite site must be large distance and could interfere with my wireless network. Attached is an amplified photo of the view. It's safe to assume that the Canopy operates in the 2.4 GHz frequency range.
    Once I connect the point at 1.2 Km, the multipoint link loses its quality, and soon the lost packets get too frequent.
    The CCK seems to be much more interfered than OFDM, I guess because of that canopies.
    Another thing I'm wondering about is if the Aironet 1310 can continuosly switch CCK-OFDM over the same point - multipoint link, without losing packets.
    What other parameters should I tweak? Is there a way to avoid interferences fromt the canopy?
    I would like to apply 100 mWatts local power using the radio with OFDM, but it seems that's not possible.
    Best Regards,
    Igor Sotelo.

  • Cisco Aironet 1200 wireless network very slow

    I have a simple wireless network set up, 2 - Cisco Aironet 1200 AIR-AP1220B-A-K9 wireless access points with 2 dBi Diversity Omni directional Ceiling Mount Antennas. They are the only devices connected to a Multitech Routfinder router, the WAN side the router is connected to a dedicated DSL connection. They are powered by AIR-PWRINJ3 power injectors. The WAP get the IP address from the DHCP in the router.
    When connecting to the wireless network it runs very very slow, the signal strength is excellent and the connection speed is 54 mbps. But when opening a web browser it takes for ever to load a simple page like msn.com. If I connect the notebook directly to the router it runs very fast. We have tested with several notebooks and have the same problem. When I view the available wireless networks in range the only two that show up are the two Cisco 1200 WAP.
    I have done the following with no improvement:
    Change the channels from auto to 6 on one and 11 on the other.
    Reset to factory defaults.
    Update the firmware to c1200-k9w7-tar.123-7.JA2.tar

    Thanks for the info.
    The documentation say not to switch from auto to full duplex or half duplex when using inline power, well I think it says the AP may reboot. I may have tried half duplex before I upgraded the firmware.
    While upgrading I disconnected the AP, used a patch cord to connect it to the router and pluged the power directly into it to make sure the wiring to the AP was not the problem and it did the same thing.
    However, when trying to upgrade the firmware it took ~ 45 minuets to upload the image and filed a couple of times retrying. I connected the AP to the notebook directly with a crossover cable and it uploaded in about 45 seconds.
    That got me to thinking that there may be a problem with the router so I have replaced it with a Linksys.
    In the mean time the DSL went down yesterday so I have not been able to test the new setup.

  • Cisco Aironet 1310 series

    hello all,
    I have a cisco Aironet 1310 series which am having problem with the signal strength. This box came with 8 dbi Omni antenna gain and am told this can go upto 5km raduis. After configuring this equipment, i could not get a link when i move 500 meters. Please find attached the configs on the box. Any help given would be very much appreciated. Thank You

    This 5KM distance is only going to be applicable in bridging situations. The following link shows how to use the distance calculations based on devices: http://www.cisco.com/en/US/products/hw/wireless/ps458/products_tech_note09186a008009459b.shtml
    In theory, if you had a really strong direction antenna on your client you'd be able to get the 1310 as an access Point from 5km, but you'd need perfect line-of-site and you wouldn't be mobile...
    As others had mentioned, if you're looking for an access point situation with that kind of range, then you need WiMax....
    but if it is bridging you want, its just a matter of getting the other link to see this one (with a good enough antenna)

  • How to change default admin password on Cisco Aironet 1040

    How do I change the default username and password on the Cisco Aironet 1040. There is a default set and I want to change that to secure the device. I've checked the manual and can't seem to find the directions. Any ideas?

    Hi Brian,
    If this AP is already registered with a WLC then you can change it via WLC.
    In WLC GUI, go to Wireless -> Select the AP -> Credential -> Override Global Credential-> Update username/pw/enable pw
    In WLC CLI, you can configure it like this. If it is for all APs, then select all, otherwise AP name.
    (WLC3) >config ap mgmtuser add username admin password Cisco123 secret Cisco123 ?
    all            Applies the configuration to every AP that does not have a specific user name.
         Enter the name of the Cisco AP.
    (WLC3) >config ap mgmtuser add username password secret
    (WLC3) >save config
    Are you sure you want to save? (y/n) y
    If it is Autonomous AP you can configure using the "username xxxx password xxx" IOS command

    Firmware 12.3(8)JEB
    Hello,
    I want to control client associations when AP load is high.
    Is there an MIB object that enables/disables client associations?
    I have searched the supported MIBS, but i could not find anything.

    An improper combination of power level and antenna gain can result in equivalent isotropic radiated power (EIRP) above the amount allowed per regulatory domain. Here is the URL which indicate indicates the maximum power levels allowed with the Cisco integrated antenna for each regulatory domain and also contain configuration setting.

          I have two buidlings acroos the street from each other.  I have two Cisco Aironet 1250 wireless AP's with the first one going in the main building with network backbone.  The Second AP goes across the street with the other wired network segment.  Both AP's have long range antenas 2.4 GHZ on top of each building.  I have configured the 1st one as the Root Bridge.  The one across the street is configured as non-root bridge.  I have both AP's configured with the same WEP key and also with the same SSID name with both set to broadcast it.   I am still unsure and confused as to how I get the non-root bridge to talk to and use the root bridge to get on the main network.
            1- It’s main to use the Root parent Mac address.
            2-  Is there another config that I am missing to get the signal? 
    Note: I still not getting any signal from the root although distance between root and non-root is 330m
    My root antenna is AIR-ANT24120 and non-root antenna is AIR-ANT1949 and attached files is my configuration files
    Thank you.

    1.  How are the AIR-ANT24120 and the AIR-ANT1949 installed?
    the AIR-ANT24120 is connected virtically on tower far 11m from the earth and AIR-ANT1949 is connected horizontally on tower far 10m from the earth
    2.  What is the distance between both APs?
    350 m
    3.  Do you have clear line-of-sight between the two?
    there is one tanker in the middle between them but it's far 7m from the earth
    4.  Is the two APs properly aligned?
    i think yes and changed the aligned many times without any news (I don't have any tools for alignment)
    5.  Which point are the antennas connected to?  Primary, Secondary or middle?
    I tried in the primary and secondary but never tried the middle antenna
    Thanks

  • Unstable Cisco Aironet 1231

    I have one Cisco Aironet 1231 access point. It does not use any kind of (server) functionality outside the Cisco device.
    I have one SSID and uses WPA-PSK (TKIP).
    The configuration seams wary straight forward, but something is wrong.
    The access point seams to be unstable. The clients use long time to connect to the access point and it looses connection a lot of times a day. Can I do something to speed up the ?negotiation process? ?
    What could be the course of instability?
    The configuration was made with the ?web configurator?, but I have a SSH/telnet dump:
    Best Regards

    A "stronger" (more gain) antenna probably won't help. An antenna that transmits with more gain also receives with more gain ..(basically, the same situation, but all of the signals are "louder")
    The general remedy, aside from the obvious of going to the least populated channel or moving to the 802.11a band, is usually to add more access points, all using some flavor of "sector" antenna (and / or "patch" antennas) to localize the area of interest.
    Because the antennas are covering a more specific area (and usually smaller area), it is usually the case that more APs are needed.
    "Seeing" 20 APs is not that alarming ... check the signal strength of each, many will usually be well-below the level that would cause serious interference. The specific level will vary, depending on the location relative to the AP<->client relationship.
    If you're seeing 20 APs, and their signal strength is roughly the same as your APs or a little lower, then you've got a problem that only a sectorized antenna system can cure.
    Good Luck
