Wireless Mesh/Backhaul question.

We have a customer who wants a wireless bridge/mesh link between two buildings. They want as much throughput as possible, better than 802.11b/g 54Mb for preference. We've identified Cisoc 1552E or I APs as suitable devices but we can't tell from the literature what sort of bandwidth we can expect over the backhaul link, will it use 802.11n speeds or are we stuck with b/g data rates? Any advice would be much appreciated.

22mb is the supported data rate I think. Why not look at the Cisco ExtendAir radio. It is 5ghz non-wifi bridge with up to 160mb of throughput and 5 9's of uptime.

  • Outdoor Wireless Mesh Design Question

    Hi,
    We have a wireless mesh network which currently is having some connectivity issues.
    One of the main issues we are seeing is with RRM configured the Mesh Access points seem to all select Channel 11 on the 2.4ghz frequency.
    I would ike to modify manually, although wondering if best practice is to use RRM or select manually.
    Thanks

    Hello Bradley,
    We'll, if you have WCS then a mismatch would happen with the cnofig template on WCS (if you have one).
    There could possibly be an AP template on the WCS to set the radio for the APs automatically.
    This is from Configure -> AP Configuration Templates -> Lightwieght AP.
    From this location you can configure a template with the AP settings and push it to the APs you want. You can also schedule the time at which the template will be applied. A recurrence also can be configured.
    So make sure that:
    - No mismatch between WCS and WLCS (you can go to Configure -> Controllers and try to audit differences between WLC and WCS).
    - Save your configuraiton on WLC if you apply it from WLC.
    - Make sure that there are no AP templates on WCS with recurrence configured.
    To avoide any mismatch in the future, I suggest you do all your configuration from WCS. This way you'll save time (if you have more than one WLC) and you'll also make sure configuration is consistent among all controllers.

  • Wireless mesh backhaul drop every 2 -3 minutes

    I have 4 1242 A/G (A is the backhaul and G is for clients, NO WLC) in a mesh with 1 as tha RAP and 3 and the MAP.  All aps have the same antenna 2.4 has patch 7.5dbi and the 5.0 has a 6dbi omni.  The syslog shows that the backhaul is dropping every 1-2 mintues because of maxreties.  The distance between the RAP and MAP is about 300ft, and the AP are about 12-15ft off the ground in a indoor parking garage for 100-40ft mass transit bus.(40 passangerbuses).  What could be causing the backhaul to drop?
    Thanks

    Was this working before and just now stopped working ?

  • Outdoor wireless mesh deployment for major events

    I am interested to hear if anyone here has any experience in setting up a large scale wireless mesh deployment that covers an area that are a few blocks.
    1. How do you deal with 2.4ghz interference as 2.4ghz and 5ghz band are unregulated. I'm not able to use 5ghz as the end devices are smartphones that do not support 5ghz.
    2. How do you deal with the backhaul capacity as each hop for Cisco Wireless Mesh would result in a 50% drop in network throughput.
    3. How do you deal with installation of the wireless mesh APs in public areas. Do you install this on a mast and leverage on the lamp post to provide power? Or do you talk to building owners to install the APs on the top of buildings? What are the challenges you face in installing wireless mesh APs in a public area.

  • 2504 WLC with 1552E AP's not able to wireless mesh

    Good day all,
    I'm seeking some assistance/help for a problem I'm havine with a WLC and 9 APs. I have a basic configuration on the WLC and I have configured one of the APs as the RAP. Now I try and add a second AP into a wireless mesh but it cannot see the RAP. They are sitting 5 feet apart but I don't see anything on the controller for the second AP. If I attach it to the wired network it can see the AP. RF-2 is solid green, RF-1 is dark, Uplink is dark, Status is orange. I understand that this means it's seeking for the RAP/MESH.
    I've tried some debug commands but to tell you the truth I am by no means a wireless expert.
    When the second AP boots this is what I see through the console
    *Mar  1 00:00:52.515: %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY

    Any assistance would be great.

    You still have two radios on the RAP just like the MAP.  As long as you are powering up the RAP/MAP with the correct power source, the radios should come up.  This means that you should have client access enabled by default on the 2.4ghz and 5ghz client access is optional.  Juat make sure that the AP/RAP/MAP is in the correct AP Group and that the WLAN is present in the AP Groups.  This will allow that WLAN to be broadcasted to the AP's in that AP Group.  If your using the default group, then by default, all WLAN's 1-16 will be broadcasted, WLAN 16 and higher will not be unless you define the WLAN in the AP Group.

    Please educate us on where to start, or the CISCO product we might need to purchase
    We are trying to branch out a new Internet wireless access and wireless phone service business in our company, and presently looking for the right Cisco product solution to purchase to enable us offer this service in LAGOS, NIGERIA.
    The service will be rendered in Africa, the country NIGERIA, and the city LAGOS.
    We would like to mount or install the product in Lagos, Nigeria.
    As we are new to this kind of service. We would appreciate if the Cisco wireless team can work with us in pointing or directing on the right product to purchase and what are required. We understand the Cisco Wireless Mesh Networking Solution, Cisco IP Generation Network, Cisco 12416 or 7600 Series Router might be the right products to purchase, but we are not sure on what needed or what are required to meet our service need.
    Possibly we would like to offer Wireless Internet Access to unlimited subscribers, and also Wireless or Mobile Phone service to unlimited subscribers in Nigeria.
    Anticipating your reply

    I suppose Cisco Wireless Mesh Networking would be a good choice.The Cisco mesh architecture makes it easy to scale coverage as capacity needs dictate, including increasing access point density; adding wired connections, controllers, and radios; and using dual high-powered, high-sensitive radios and a selection of high-gain antennas.Refer the document for IP NGN in the following URL http://www.cisco.com/en/US/netsol/ns537/networking_solutions_solution_category.html

  • Enterprise Wireless Mesh License needed for controller and AP's?

    If I have a 2112 WLAN Controller and 7 1240AG AP's what licensing do I need to purchase to enable enterprise wireless mesh? Do I need to get the license for the controller (AIR-AP-LIC-M-12)? A license for each AP? Both? Thanks for any replies!

    Hi Andy,
    You only require the Mesh license for the Controller not for the individual AP's :)
    Solution
    The Cisco EWM license is required for wireless mesh deployments for the indoor access point platforms, including the Cisco Aironet 1130 and 1240 Series. For the Cisco Aironet 1500 Series, these licenses are not required. These EWM licenses are required for all the WLAN controllers when mesh indoor acess points are associated with the controller. Each WLAN controller has a corresponding EWM license. The license entitles the user to configure as many mesh indoor access points as the controller allows.
    The license SKUs are as follows:
    • AIR-AP-LIC-RTU=, Cisco Advanced Feature License
    • AIR-AP-LIC-M-6, Cisco Advanced Enterprise Wireless Mesh, 6-AP Controller
    • ***AIR-AP-LIC-M-12, Cisco Advanced Enterprise Wireless Mesh, 12-AP Controller
    • AIR-AP-LIC-M-25, Cisco Advanced Enterprise Wireless Mesh, 25-AP Controller
    • AIR-AP-LIC-M-50, Cisco Advanced Enterprise Wireless Mesh, 50-AP Controller
    • AIR-AP-LIC-M-100, Cisco Advanced Enterprise Wireless Mesh, 100-AP Controller

  • *wireless mesh networking*

    can a wireless mesh networking application be built using the sun java wireless toolkit??if yes ...then plz tell me how to do it..

    The distance at 54 Mbps for 2.4 GHz side of the mesh (client access) is basically the same distance as it would be with most 2.4 GHz Access Points.
    That said the "indoor range" being 90-100 Ft and outdoors being further because there are no obstructions. Now the Cisco Aironet 1500 does have an amplifier and a higher gain 2.4 GHz antenna enabling it to transmit further but how far that goes at 54 Mbps depends on the client being used (and the Access Point's ability to hear same).
    remember just because the Access Point is improved (the client is typically operating at lower power and in some cases with an internal antenna so distance it really a matter of the client used and the environment it is used in. So there is no real exact answer as it varies but I'd expect to get at least 140 Ft or more outdoors at 54 Mbps. Again, you'd really have to test it with your specific client in your environment more more accurate numbers.

  • 1510 Mesh AP Secondary Backhaul question

    Our outdoor 1510 APs are currently a bit too far apart in some cases. Although I am currently planning fill-in nodes, I want to get something working on these nodes that are too far to mesh on 5.8.
    I have enabled secondary backhaul on the system, and was expecting performance similar to what I am used to on other mesh systems that mesh on 2.4. However I saw no improvement at all. I can't even find any statistics on the usage (if any) of 2.4. At the moment, I am pretty disappointed.
    It is almost like the feature doesn't work. I'm on 4.1.185.0 and am just a bit reluctant to switch to the mesh-only firmware until I hear some reports from actual users.
    Does this feature even work? Is there anything else I must do besides turn on the feature from the CLI?
    Thanks

    Hey! Thanks for the info.
    I have moved to the mesh firmware and the latest WCS since I posted this question. I received some info from the TAC as well, but always want to know from someone who actually has it working.
    The commands I was given were:
    config mesh secondary-backhaul enable (manual mode)
    config mesh secondary-backhaul enable force-same-secondary-ch (force mode)
    show mesh seconday-backhaul
    show mesh secbh-stats Will show you if the seconday is being used
    I'm not sure if the first two are either/or though, and also what the second one actually does.
    They also told me that RRM has to be disabled and the two radios have to be on the same B channel. That's a lot of management to have to do. I would have expected the B channels to listen ank know who and where their neighbors are and be able to handle this. If this is the case, I sure hope improvements are in the offing!
    I'll try to get the config posted, but in the meantiime please let me know any insight you have on getting it TO work. The person I spoke with at TAC had never actually talked to anyone with it working.

  • Outdoor Wireless Mesh 1524 AP Power Question

    Hello Group,
    I curious, if I have a 1524PS AP that I would like to power from a power pole and the power pole does not have a street light or street light power control on it today but it does have 480V/277V power source, can I still use the power source directly by wiring the 40ft power cable in directly. I would think not, but I am getting a lot of questions about this lately so I am looking here for some help.
    From the cisco documentation it says we can use 480V power sources. However, its a bit ambiguous in some places stated that it can be done if you use a street light power tap - is this just a power cord or does it include some sort of transformer as well?
    My understanding is that most 480V systems in scenerios like this are 2-phase. However according to the cisco documentation for the 1524 AP you can power the AP via 90-480V power source. I am little nervous to try that here. I know 277V can be dangerous. Will the Cisco AP support cutting the existing power cord (40ft) and wiring it directly into a 277V/480v power source off the light pole? I have been getting conflicting reports from the documentation and others. Any help here would be greatly appreciated.
    Is the AP power supply capable (via a transformer of some sort) of converting direct 277/480V power to something usable via the AP? The 40 ft power cable supplied with the AP looks like its made for 110/240 only so cutting and rewiring it hot into the 277V source could be dangerous correct? 
    If someone could give me a definately answer here it would be greatly appreciated. We can't proceed until we figure this out.
    Thanks in advance

    Hello Bradley,
    We'll, if you have WCS then a mismatch would happen with the cnofig template on WCS (if you have one).
    There could possibly be an AP template on the WCS to set the radio for the APs automatically.
    This is from Configure -> AP Configuration Templates -> Lightwieght AP.
    From this location you can configure a template with the AP settings and push it to the APs you want. You can also schedule the time at which the template will be applied. A recurrence also can be configured.
    So make sure that:
    - No mismatch between WCS and WLCS (you can go to Configure -> Controllers and try to audit differences between WLC and WCS).
    - Save your configuraiton on WLC if you apply it from WLC.
    - Make sure that there are no AP templates on WCS with recurrence configured.
    To avoide any mismatch in the future, I suggest you do all your configuration from WCS. This way you'll save time (if you have more than one WLC) and you'll also make sure configuration is consistent among all controllers.

  • Mesh design question

    Dear Sirs.
    My customer plans to extend existing wireless coverage and upgrade to controller based network.
    Let me shortly describe the situation based on the attached network map.
    RAP points are installed on the buildings, they have wired uplink.
    MAP points are installed outdoors (in the IP66 sealed ABB boxes) on the poles (height 5 m), only power is present on the poles, no wired uplink.
    Now MAPs (Non root bridges) are connected to RAPs (Root bridges) via 5 GHz interface in bridge mode.
    Red points: already installed Autonomous APs, 1242AG model.
    Green points: APs planned for installation.
    1. In order to upgrage to controller base network I want to install two 2504-25 controllers in failover mode. I have AP-to-LWAPP-Upgrade-Tool and is familiar with the image upgrade procedure. However, I have a question: if I upgrade all existing RAPs and MAPs to LWAPP mode, how the MAPs without wired uplinks will connect to RAPs and then to controller? Should I have physical access to their console port to issue some CLI commands to connect to RAPs?
    2. Can 2504 controller be configured for operation in mesh network mode without additional licenses?
    3. For network expansion I plan to install 3502E access points in sealed boxes. I chose them due to separate 2.4 and 5 GHz antenna ports, in order to use omni antennas for 2.4 client coverage and 5 GHz directional antennas for wireless uplinks. The distance between APs is abou 100 - 250 meters. Is it recomended to use directional antennas for wireless uplinks or I can take 1602E (or 2602E) access points and dual band omni antennas and install a good working mesh network with 5 GHz uplinks on omni antennas?
    4. Can 2504 controller work together with 1242AG, 1602E and 3502E points?
    5. How should MAPs be preconfigured to begin working in mesh network after powering them up on the poles on site?

    > The MESH AP's along with your other access points (lightweight) will obtain their code from the WLC when they join. I would always stage the MESH AP's prior to mounting them to certify they work and they can form a link. You would need to purchase a power injectors for each RAP and get a AC power adapter for each MAP.
    The Upgrade tool is to only convert autonomous AP's to lightweight. They stopped supporting 802.11n access points in that tool.
    2. Can 2504 controller be configured for operation in mesh network mode without additional licenses?
    > With the newer code version you will be using, yes. You can have both MESH and traditional Local mode or FlexConnect mode access points.

    > If these are going to be exposed to the outdoor elements, then you need an outdoor antenna. It's hard to say what antenna you need, but if your using a 3502e, make sure you get an antenna that is a 3 lead so you can utilize all 3 antenna ports. Patches are directional, so if you are going MAP to MAP to MAP to RAP for example, you would need an omni. Patch works if your going Fromm MAP to RAP.
    4. Can 2504 controller work together with 1242AG, 1602E and 3502E points?

  • Essential items to create a wireless mesh network

    I want to create two independent wireless networks (2 different SSIDs)
    with 3 APs each one of the cisco 1552 series (outdoor Accesss Points) in a mesh topology.
    The one network will have 3 1552s APs and the other 3 1552e APs
    My question is which cisco items I need plus to the APs (except the antennas)
    1. Wireless LAN Controller (which type? one or two?)
    2. Wireless Control System Software (Is it essential?)
    3. Other...

    You would get two wlc to provide redundancy.  You can look at the WLC2504 for smaller environments or else look at the WLC 5508 if think you will be growing.  The WCS is end of sale and you would need to look at Prime Infrastructure 1.3.  This is optional and is not required to have a wireless system up and functional.  It does help in larger environments and for troubleshooting purposes.

  • Wired/wireless traffic general question

    I originally set up my Airport Extreme without much expertise on WiFi or routers, but I want to raise my knowledge base now.
    My current question: In general operation with both ethernet and wireless clients, obviously all the traffic with wireless clients is broadcast over RF to anything out there that can receive them, but is any of the traffic between the base station and the ethernet clients also broadcast over the RF signal? To put it another way, can eaves dropping on the RF traffic also allow eaves dropping on the ethernet traffic?
    Are there any good educational books like a Missing Manual or such on WiFi or Airport?

    A lot of very interesting aspect of "others experience w/airport". I'm also in a suburb w/a lot of WiFi, other variation's of the same, and Airport traffic. One early concern I had was the  Rf-AP system starting up, as it does right out of the box. Not knowing this, (at least at first) was for me an embarrassing  wake-up call. As for near-by WiFi/and other "dish, etc" systems, A few thing's I noticed, and thanks to associate's who know WiFi/Rf tech very well, a few observations, for what it's worth. Regarding "Ghosting" of certain signals, it is almost inevitable for many reasons. It's a bit like (usually and harmlessly) being at a crowded party, where you "hear" many people jabbering away, but don't really know "what they're saying, other then 'something."
    Oddly enough, I have an associate who calls that (a bit like a cheap hearing aid) "Rf, or harmonic din". As for it being problematic from a security point-of-view one needs to isolate "sections" from one "broadcast" which I'm told is rather low tech, as a first step to having one "borrow your specific signal,' for say either sub-Walmart (cheap bas******) access to the net thanks to your WiFi AP. As you mentioned, w/so much depending on the chronic pain that's all based on passwords, well, we know the issue w/that.
    Several aspects of trying to maintain some dignity in not getting hacked for whatever intent present repeated problems. I was hacked, and it was (unfortunately not benign). Believe me. Since , I have done everything short of active EW suppression (FTC, and anyone in range would be understandably ******-off.) Your comment about "flat signal strength" I'm told is screaming, "I'm blending in, move on." Varying sig strength is one way to blend in yourself, but only a bit. 
    But WiFi signal structure has certain quiescent properties reported in the literature (I read it on physorg.com, or technology review I think) that makes that soft engulfing-Rf nature of WiFi useful, Ex: for those who want to know, or really just be aware "someone, a pet", etc; who is moving around a room, compared w/the stuff in a room, building, etc. That attribute provide's a technical/mathematical  yardstick that is at least one reproducible and exploitable aspect of the technology. As with that noisy background "party din," it's why noise in general can be cut through as long as you get even a small piece of a conversation.
    I've looked at passive material "blankets" that smother Rf. Certain conductive polymer's woven in the density of a gym mat are somewhat useful if its something serious enough. Naturally, (pricey) and by no means perfect. Beyond that one can use old power company techniques developed to know where a line goes down, for example if using a hard line. Since ac can be modulated, it can also be run through what looks like a small old desk-top pc cpu tower. ****, anyone can buy a plugin, looks a small 120vt-12v transformer you plug in the wall ac, and that turns ones household wiring  into a local, house/office Rf wireless network.
    In the end it can get surreal, silly, paranoid. or just sad. Been there too. Anyway, best of luck. Bob.
