Cisco Wireless Deployment High Density

Hi my name is Ivan
I have a question
We need to work a network with high performance data applications, voice and video for a University. We have done tests with a user downloading files 4GB and simultaneous video calls with skype, and we note that the video quality is degraded, as well as the file is cutting and canceling the download, as we mobilize for campus. 
We would like to know if the problem coexists in performance or coverage or both. 
To what extent we can tune the configuration of the Cisco WLC for better service delivery. 
Any recommendation please 
Thank you. 
Ivan

1.  When the video calls was on-going, what radio was this being carried over? 
802.11a,g and n
2.  What is the model of your WLC? 
Cisco WLC 5508 in HA AP SSO
3.  What is the model of your AP?
73 Cisco AP 3600 and 17 AP Cisco AP 1552
4.  What is the firmware of the WLC? 
7.4.121.0
5.  Did you check for co-channel interferrence? 
Yes, exist co-chanenel inteferrence
6.  What is the speed of the APs wired Ethernet link?
1GBEthernet
7.  Did you check for speed/duplex issues of the wired Ethernet link? 
There is no  exist issues of speed/duplex
8.  What is the LAN backbone speed from the switch up to the WLC? 
1GBEthernet
9.  When doing the video calls, how many clients were associated to this AP?
We have  tested with  one user, using video calls, downloading of 4GB, sharing files by wireless network, and the conectivity is too long
Thanks for your answer.

  • Wireless high density - Cisco vs World

    For wireless environments with high density of clients many manufacturers (Meru, Xirrus, Ruckus, Trapeze, ...) have developed equipment and capabilities optimized to provide good performance, these features are mainly based on the use of a single channel, or the use of smart antennas and arrays. In theory, these features are quite reasonable.
    But Cisco is among the few manufacturers who think that with proper design (based on microcells) can obtain a better performance in dense environments, without necessary equipment or special features. I have had problems in high density environments with Cisco, but I could not prove in practice the solutions of other manufacturers.
    Has anyone been able to compare both methods in the same environment? Cisco is right? What are the most important considerations to take into account in a high density environment with Cisco equipment?
    Thanks

  • High density wireless deployment question

    Hi,
    I have read in some documents that we should have one Ap for more or less 50 clients.
    But i also read for example in ap 2600 specs that it support maximum 200 connections per radio.
    So for example in a conference room (10mx5meter) for 150 users in theory can i have just on Ap2600 for web surfing or i should have 3?
    Best regards
    MC

    The max that you see on the data sheet does mean you can have x amount connected, but doesn't guarantee any throughout. The rule of thumb is 25 clients per AP. High density in a school is having like one AP per room that may hold up to around 30 students. Also including APs in the hallway, etc. Office areas can be the same. One AP per 25 or less users. Auditorium or large open areas are difficult to do high density like what I mentioned above because of the signal bleed in open areas. It's harder to control that. In these areas, you might look at the stadium APs and the stadium antennas.
    Just remember, the amount of clients depend on the application that is being used on the wireless. If your doing video streaming, you may only have 8 devices connected before the user experience starts getting affected. Wireless is half duplex. So you take the max throughout on the 2.4ghz using. 802.11n and you divide that in half. So 144mbps is actual 73mbps throughout for one device. Now with two devices, you divide that again in half, so 36mbps for each and so one.
    Hope this helps you understand.

  • Wireless Site-Survey for High Density Environment

    Hi,
    I have done many Wireless SIte-Surveys in my career. But this will the first time, I am going to do a Site-Survey for High Density environment (School with Byod 1:1 design).
    Currently, the school has a Wireless network in place. The current wireless design includes 3502 APs, 5508 WLC and Cisco Prime. The customer has issues with sufficient bandwidth in classrooms which limiting the students and teachers to access the learning content.
    It is understood that there was no initial Site-Survey conducted, the AP positioning was made based on their knowledge.
    Now, I am not sure as how to conduct the Survey here?
    Do I need to conduct an Active Survey by connecting to the existing Wireless Network in the School? Or just passive Survey will be enough to determine the exact issues with the current design and provide the recommendations?
    I have gone through the Cisco High Density design and white papers to start with.
    Thanks,
    CJ

    Before you do the site survey, I'd do the initial breakdown of the LAN.
    1.  What kind of switch ports are we talking about?
    2.  Are the APs connected AND negotiated to 1 Gbps ports?
    3.  What is/are the switch uplinks?  100 Mbps, 1- or 10- Gbps, Etherchannel?
    4.  Line errors on the links between the AP and the switch, uplinks and the link between the WLC and the switches?
    5.  WLC link?  How many are used?  Are they LAG or not?
    6.  Configuration of the WLC must be checked.
    Once you've checked these do I start talking about wireless:
    1.  What problems are the staff/students experiencing?
    2.  How many APs to a classroom?  How big is the class?
    3.  Determine what kind of traffic are each class trying to push?
    4.  Where are the APs located in relations to the staff/student?
    5.  Verify co-channel interferrence.  I know they have 3502 but I've seen people disable CleanAir.
    6.  Verify what kind of NIC cards are used and whether drivers have been updated or not.
    I'm in the middle of improving our wireless coverage in >98 schools.  This means I am now deploying 1 AP per classroom.  In areas where the students/staff converge, I put additional APs (both indoors and outdoors).

    You are correct, between the higher numbers of users with multiple devices the bandwidth requirements keep increasing.
    The limitation of three non-overlapping channels in the 2.4 GHz space is driving more customers to 5 GHz, it is important to have both bands when high density deployments are needed.  While many older devices only support 2.4 GHz, we are now seeing far more devices with 5 GHz as well.
    The recomendation of 20-25 clients and 8 voice calls on a given 2.4 GHz channel is still a good "rule of thumb" with actual customer data requirements driving those numbers higher or lower. You are right when you say "throwing Access Points" at the problem can degrade the wireless quality as co-channel interference and overall noise floor can rise with multiple Access Points that can all hear each other.
    A better approach to the problem is to throw more spectrum at this issue (using 5 GHz channels) and elements of 802.11n (20 MHz) bandwidth on 2.4 GHz.
    What we have been doing in high density deployments is to try to minimize the propagation of a cell and focus it in a given direction.  This can be done by
    1. Managing the RF power of the radios (Access Points) and in some cases the client's power (using elements of CCX).
    2. Using the right antennas to shape both Tx and Rx cell size to help isolate, we have recently introduced a new high gain antenna for stadiums that does this well.
    3. Limit supported rates, obviously the higher the data rate the less sensitive the receiver is and the smaller the cell size becomes.
    4. Enable 5 GHz (that adds far more channels for data throughput)
    5. Limit the number of SSIDs in use as each requires a separate beacon (adding to RF utilization)
    6. Co-locating access points with non-overlapping channels
    There are some challenges, for example; many dual -band clients prefer to connect to 2.4 GHz, and 2.4 GHz is more likely to be busier and subject to interference, so we also enable Cisco "Band-Select" which basically "nudges" those clients off 2.4 GHz and pushes them to 5 GHz so as to free up the 2.4 GHz band when we can determine the client has 5 GHz capability.
    So how is this done? well, we do this by listening to the clients and if we detect that the client is sending out probe requests on both bands we know the client can use 5 GHz so we essentially make the 5 GHz band "appear more attractive" to that client.
    Note: Client load balancing and Band select are features in the Cisco Unified controller menu.
    Also enabling client link (intelligent beam forming) helps direct the signal directly at the client and reduces same channel interference.

  • Outdoor High-Density/Mixed Environment Cisco AP/Antenna Choices for Data Coverage

    We are looking to upgrade our non production use wireless network, which is for providing users typical internet data services. We don't have any wireless engineers on our team, we are primary wired networking guys. We are upgrading our wireless network, because we have a lot more user joining and our AP's in place have too high a client count which has diminsed throughput speeds for our customers. We have two seperate areas that provide this coverage, and both of them are under 1sq mile in size (one is 417,000 sq ft in size/280 estimate users and the other is 590,000 sq ft in size/700-800 users estimate). The environment is rugged (hot/humid/sandy), but flat. The users occupy pods/trailers/tents, so no structure is higher than 15ft.
    Within the last year, more users are bringing in smart devices for data services, so our our network is a hybrid network now with a higher-density of users, and 802.11n AP's appear better equipped to handle this kind of load. We currently have a mixture of 1142AP's in side and 1252/1262 AP's outside place in NEMA enclosures, which are tied to two 3560/3750 PoE switches at each location. We don't have enough AP's in place to handle the additional client load to provide suitable data throughput speeds for typical internet data services, and are looking at possibly revamping the whole wireless network with different gear.
    We are looking at possibly removing all previous AP's, and putting in place Cisco 1552e AP's (AIR-CAP1552E-A-K9) in both areas, using 3 Cisco dual antennas (AIR-ANT2547V-N) per AP's. We've seen an excel doc floating around on the web to help plan for how many AP's we might need, but the minimum area size for the excel spreasheet calculator is 1sq mile, which is a lot more than what we are looking at for each area. We've attempted to use the WCS in planning mode to map out how many 1552e AP's we need for each area (with our maps we created using Google Maps, and fairly accurate), and reviewed the heat signatures created and it appears the AP count is too high. We got around 20 AP's for one area and 33-35 AP's in the other area, which seems very high. We are looking at mounting the 1552e AP's to poles in each area at a height of around 12-15ft.
    We don't know what the client load a 1552e AP can handle, for providing throughput speeds of 1.5Mbps to 5Mbps, to gauge how many AP's we really need, and whether going for using strictly 1552e AP's is the way too go. The 1552e AP's are geared for MESH networks, which is very different from what we have now. Can we set-up the 1552e AP's as stand alones? Do we have to use a different antenna for whatever AP is going to be the RAP? We are looking at using Power Injectors to provide power to the AP's.
    Thanks in advance for any suggestions.

    That setup is your best bet. What you have to look at is the number of hops. I would typically don't have more than two hops. That is map to map to rap. Remember that the 5ghz is your backhaul and you are basically daisy chaining your mesh. What you need is to make sure your 5ghz can link IP with a good backhaul speed. The 2.4ghz will of course cover more area so when you place these mesh AP's, make sure your backhaul has coverage to meet your backhaul requirements. Antennas will be the same for a map or rap. You will need a WLC to actually do mesh and it would be better that way. Even though you can get an autonomous version, it would be a dumb ap per say. Stick with mesh and a WLC and you should be fine.

  • High density wireless

    hi all,
    does cisco have a wireless solution for a high density, 1-2000user wireless enviroment? 802.11n in the 5ghz spectrum with the appropriate design obviously... but does cisco make an access point designed to handle several hundred associations?
    thanks

    i've successfully used the 1242aps, with a wlc4404... using both 802.11a, and 802.11b/g... though b/g can be miserable when the mass of laptops converge and step all over the 2.4GHz band. luckily about half the laptops that come in default to using 802.11a, and see no issues.
    using these aps, i've found that allowing the wlc to dynamically adjust the power down to create smaller "cells" tends to help.. but there's no way around all the noise the large number of laptops create... at least in my experience.

  • Inline Posture deployment for non Cisco Wireless Controler

    Hi all of you
    I have to deploy an Inline Posture to manage non Cisco Wireless Controler ( ZoneDirecteur 1000 Ruckus), It seem easy but I don't know from where to start. All documentation I rode it's about Inline Posture for VPN. I want just to use this Inline Posture to manage Wireless user through ZoneDirector wirelss controler. Thank you.
    Regards
    Kouassi

    So what is the solution for this scenario?
    remote site has non-cisco autonomous wireless AP. NAC is centralized. I can not use OOB since there is no support for non-cisco AP in OOB mode. As a result I use InBand mode. This means that local wireless trffic in remote site must travel to central site, go through NAC Server and go back to remote site. Is this correct?

  • Wireless Internet Access (Cisco IP NGN or Cisco Wireless Mesh Networkin)??

    Dear Cisco Wireless Team
    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

  • High density WLAN scenario

    Hello,
    Next week I'm facing a high density WLAN scenario, so I'm gathering info related to WLAN config advices, expected issues, etc. I've read Cisco WLAN High Density WLAN guide, but I'm still having questions about how my WLAN network will react to a high density scenario, i. e. auditorium with 800 seats. I'm planning 4-5 APs, maybe one in each corner and one in the middle.
    My gear is Cisco WLC 5508 v7.4.100 with a mixture of 3600, 2600 and 1142 APs. I'm a bit doubtful about certain issues, related to high number of devices (specially iPhones and Android phones) trying to get connected to WLAN network. Regarding radio frequency planning, allow only high modulation levels, is there any other config I can set in order to force wireless clients to stop trying to associate to a certain AP? Is client-balancing setting working well with iPhone and Android phones?
    My other concerns are about what info and graphics should I watch in real-time in Cisco Prime. Certanly, number of clients per Ap, but, anything else?If I get AP saturation, how should I react? Moving or adding APs? Rising modulation level?
    Any advice will be greatly appreciated.
    Kind regards,
    Libera TAC team.

    I disable 1,2,5.5,6,9 and 11 Mbps, 2 to 54 are supported, TPCv1 is enable, but I´m using fixed power because the WLC assigned low power and clients get low signal. Now I´m testing an area using 1-24 Mbps as disable and 36, 48 Mbps as supported and 54 Mbps as mandatory, do you think that with this set up will we be able to manage high power level?
    Here, we have serveral clients into small areas, so we have lot of APs for the amount of clients.

  • Interoperability of cisco wireless products?

    I've been doing a lot of research on various Cisco wireless products and the options are kind of confusing.
    I'll start with my deployment; I have two locations both of which have a manufacturing and warehouse environments (no climate control) and regular offices.
    Location 1 needs 3 APs on the production floor and 1 in the offices.
    Location 2 needs 5 APs on the warehouse floor and 4 for the offices.
    I was thinking about using the Cisco 521 APs for both the production floor and offices and the Cisco 526 Wireless Controller for Location 1.  I figure that will give them room for expansion and keep the costs low.
    For location 2 I was thinking about the Aironet 1240AG APs for the warehouse floor, Aironet 1140AG APs for the offices and then a Cisco 2112 Wireless Controller to manage all the APs.
    Both locations require WPA (or WPA2) encryption and roaming.
    My questions are:
    Will the 521 APs work with the 2112 controller?  For that matter, what sort of interoperability is there with the APs and controllers?  Can I manage any Cisco AP with any Cisco Controller?
    Are there any cheaper APs than the 1140AG that will work with the 2112 controller?
    Is the 1240AG a good choice for a non-climate controlled warehouse environment?  The APs are going to be mounted on the ceiling which is roughly 50 feet high and I'm going to be very upset if I deploy these APs and then have one fail during the summer 6 months later because it wasn't made for volatile environments.
    The 521 APs are only going to be about 15 feet up so they can be accessed with a ladder so I'm not so worried about them.
    Thanks!

    Will the 521 APs work with the 2112 controller?
    No.
    Are there any cheaper APs than the 1140AG that will work with the 2112 controller?
    You could try the 1130.  1140 supports 802.11n while 1130 is a/b/g only.
    Is the 1240AG a good choice for a non-climate controlled warehouse environment?
    The 1240, like the 1130, supports a/b/g only while the 1250 supports a/b/g/n.  The newer 1260 is controller-based only.  The 1240, 1250 and 1260 use external antennae that's an OPTION.

  • MacBook Pro will not connect to Cisco Wireless Network

    I have just bought a brand new MacBook Pro, running Leopard (OSX 10.5.1) and I just cannot get it to connect to the Wireless Network at my workplace.
    The MBP connects to wireless network and authenticates just fine, but will not obtain an IP address from the DHCP server.
    The wireless network consists of 16 Cisco Aironet 1200 Access Points controlled by a Cisco Wireless Network Controller. It does not broadcast its SSID and is WEP 128-bit hex protected.
    Changing the network from WEP to WPA is out of the question for me as this is under the control of my customers IT Department and they do not have any problems with their PCs connecting to the network. It appears to be an Apple issue.
    For reference, my old Vaio PC, my Nokia N95 and my iPod Touch ALL connect to the same wireless network without any problems whatsoever, first time, every time!
    If I boot into Windows XP from my Boot Camp partition, XP can connect wirelessly to the network without any problems, so it is not MacBook hardware related...
    It has to be a bug in Mac OSX... doesn't it?!?
    Things I have already tried (following suggestions on many forums):
    * Switching Airport off/on
    * Deleting various network-related Plist files and rebooting
    * Manually assigning an IP Address (not really permitted but doesn't work anyway!)
    * Disabling all network adaptors except Airport
    AP Grapher shows that the MBP is connected to the wireless network, at good strength, and packets are being sent and received, but Internet Access is not possible as no IP Address has been assigned. Instead, my MBP shows a 169.* IP Address (self-assigned). It should be a 10.1.255.* address.
    Can anybody please help? Thank you.

    i posted this same reply elsewhere because it worked for me for my Buffalo wireless router: try manually setting your IP address instead of relying on DHCP, which sometimes (I don't know why) doesn't work well with Macs. It's a good get around. I am a happy Mac user but nothing is perfect on earth, and when the Mac gives problems, it does give a lot of frustration. Macs are not as easy to troubleshoot as Win because a Mac is built to be user friendly(and it works most of the time), meaning a lot of the background computing stuff is hidden away from users to avoid user accidentally upsetting some settings.
    Unfortunately, the highly automated troubleshooting wizards provided by OS X are not perfect so when these software wizards fail to resolve the problem, like my Network Diagnostics, I have to spend more time tinkering around. There's "Terminal" of course but then most of us, especially PC converts to Macs, don't know how to use it.
    You should also try updating your MBP, see if there are any new updates being released.

  • Cisco Wireless Location Appliance

    dear
    i have WCS with 500 ap License
    i need to have Cisco Wireless Location Appliance what lisens i need for 500 ap
    please explain to me that

    Hi Ahmed,
    This is the upgrade License SKU for upgrading WCS to WCS Location;
    WCS-LOC-UPG-K9
    Supports deployment of Cisco WCS on a single server only.
    For customers upgrading from their existing Cisco WCS base licenses to equivalent Cisco WCS location licenses running Cisco WCS Software Release 4.1 or later.
    Available as Cisco WCS location in increments of 50, 100, or 500 lightweight access points.
    Customers currently using this license with Cisco WCS Software Release 4.0 are encouraged to upgrade to Cisco WCS Software Release 4.1, but they are not required to do so.
    Order the Correct Cisco WCS SKUs
    The process to order Cisco WCS SKUs for WCS-STANDARD-K9, WCS-LOC-UPG-K9, WCS-WLSE-UPG-K9 and WCS-ENT-K9 is presented below. To request help with ordering, please contact Cisco Customer Service: http://www.cisco.com/go/customerservice.
    1. Login to the Cisco Ordering Tool.
    2. Enter the family SKU of WCS-STANDARD-K9 or WCS-LOC-UPG-K9 or WCS-WLSE-UPG-K9 or WCS-ENT-K9 into "Enter Product" in the Ordering Tool and then press "Enter."
    3. The family SKU will display in the ordering area. (Figure 6).
    4. Select the "Line" for the family SKU
    5. Once you have been taken to the configuration screen, select one of these options from the left side (Figure 7):
    For WCS-STANDARD-K9 select one of the sub-SKUs based on the following:
    Base: WCS Standard AP Base Option
    Location: WCS Standard AP Location Option
    For WCS-WLSE-UPG-K9 select one of the sub-SKUs based on the following:
    Base: WLSE to WCS AP Base Upgrade Option
    Location: WLSE to WCS AP Location Upgrade Option
    **For WCS-LOC-UPG-K9 select the sub-SKU:
    **WCS AP Location Upgrade Option
    For WCS-ENT-K9 select the sub-SKU:
    WCS Enterprise AP Location Option
    For the WCS-STANDARD-K9 or **WCS-LOC-UPG-K9 SKU families, customers are prompted to order the optional CD (WCS-CD-K9), for a nominal charge, during the ordering process. The WCS-CD-K9 contains one software image of Cisco WCS Software Release 4.1 on a CD for Windows and Linux. This CD is shipped by U.S. mail to the purchaser's address. The optional CD is not available for WCS-WLSE-UPG-K9 because this SKU family already ships in CD format.
    6. The right side of the screen will display the licenses available (Figure 7). The price for each SKU is displayed in the Ordering Tool.
    7. Each license is orderable in a quantity of one (1) for the quantity blocks specified. To add multiple quantities of license blocks, you must go back to the main screen and order additional family SKUs and then select the sub-SKU option and license quantity block required. Repeat this process as needed, until the correct quantity of license blocks for your sub-SKU have been ordered.

  • Best wireless deployment at Remote Sites - designe

    Dears,
    I have many remote sites with Hub and Spoke topology, and I have Cisco wireless controller 5508 on our HQ serve the wireless network at HQ (approximate 25 Aps)
    The business need to deploy the wireless on RSs for public customer (not for employees).
    I have concerns about security if we going to terminate the SSID - for public- at Remote sites toward HQ over WAN connections (viruses, malware, sniffing … etc.) to control it using our Cisco wlc even if I terminate the vlan represented this SSID toward our firewall (on dedicated DMZ), and congestion will happen since this SSID will be used by the public (Non-employees persons).
    Please your kind suggestion.
    Thanks in advance

    Hi,
    For you scenario.
    Below deployment will work

  • Cisco Wireless Implementation

    Hi,
    We are in process of deploying cisco wireless infrastucture using WLC 5508 and AP1252. However, just curious to know what are Cisco best practices regarding VLAN design for these components. Can they belong to same VLAN or we need to provision separate VLANS for WLC and APs.
    Appreciate your early response.
    -> Ripu

    500 APs will be fine.  The number of clients isn't an issue here, it becomes more of an issue depending on the setup of your wireless infrastructure, you probably wouldn't want 1000s of users on one big flat network.
    Hope this helps,
    Thanks
    Chris
