Outdoor Enterprise Mesh 802.11n deployment

Hi
Is Cisco WCS mandatory when deploying an outdoor enterprise mesh solution?If I am goin to use the 1552E purely as an outdoor access point ,do I really need the Cisco WCS?
Sumesh

NO Not mandatory... WCS is a management software where in we can manage the wireless network.. if WCS is down network will not be down.. Lemme know if this answered ur question!!

  • 802.11n greenfield in a mixed environment

    we plan to have mixed 802.11n deployment coexistence with a/b/g clients. But we want to have some classrooms or labs to run greenfield only where people request 100Mbps bandwidth to transfer large images. What is the best practice to design some small greenfield areas in the mixed environment? And what is the best way to prevent 802.11a users to associate to our 1140s?
    Thanks!

  • Data and Voice separation with 802.11n

    Hi there
    I'm interessting in some design guides. I would deploy data in 2.4 GHz band and the voice in 5 GHz band. But aren't there problems with the 802.11n deployment, I thought that this works better in 5 GHz.
    What recommendations would you make and did you have some issues with this design?
    Thanks in advance.
    Dominic

    Hi Dominic,
    You can find all kinds of documentation on Cisco's 802.11n homepage: http://www.cisco.com/en/US/netsol/ns767/networking_solutions_package.html
    To answer your questions, there is no "problem" with running 802.11n in the 2.4GHz space, but there are limitations. You cannot use channel-bonding, which is the primary source of the added bandwidth that 802.11n offers. If you want to see 150Mbps data rates, you'll need to deploy it in a 5GHz implementation.
    Another advantage to running in 5GHz is that you can isolate your 802.11n traffic from your 802.11b/g traffic on the 2.4GHz radio. This will prevent slowdown that can occur when legacy clients coexist with 802.11n clients.
    So yes, you're correct to say that it does work better in 5GHz. The nice thing is that most 802.11n chips in laptops support this band.
    That said, it would be best if voice and data can both exist in the 5GHz space. You can accomplish this by creating different SSIDs for your voice and data networks. There is nothing wrong with deploying both in 5GHz.
    Let me know if you have anymore questions. Thanks!

  • More explanations about MESH and 802.11n

                       Hello,
    I just begin WiFi installations and I have some existential questions.
    I have 5 Cisco 1552-E APs. One of them is wired to LAN and act as RAP, the 4 others are MAP.
    On each AP, I use 1, 6, 11 channels as 2,4GHz non-overlapping channels.
    As I have a 802.11n network, I use 5GHz band with non-overlapping channels too. Because I'm in Europe and outdoor, I want to use 100, 112, 124, 136 and 140 channels.
    But all the 5 APs have a MESH backhaul 5GHz link to connect to LAN.
    Please clarify my mind, because I don't understand how it is possible for 2 APs, to communicate between themselves on a different 5GHz channel ??
    Thank you,
    Clement

    There is a new model which has 3 antenna ports for the 5ghz and 3 antenna ports for the 2.4ghz. This allows you to use one of the Cisco mesh patch antennas for a longer backhaul shoot to the RAP or even a MAP. It's hard to say what you can do but that gives you more options.
    Cisco Aironet 1552E/1552EU External Antenna Access Points
    The Cisco Aironet 1552E/1552EU Outdoor Access Points are the standard models, dual-radio system with external antenna ports that are compliant with IEEE 802.11b/g/n standards (2.4 GHz) and 802.11a/n (5-GHz). The 1552E has three external antenna connections for dual-band omni or directional antennas. The 1552EU has six external antenna connections, three for 2.4 GHz and three for 5 GHz antennas, that support omni or directional antennas. They have Ethernet and fiber Small Form-Factor Pluggable (SFP) backhaul options, along with the option of a battery backup. These models also have a PoE-out port that can power a video surveillance camera or other devices. Highly flexible models, the Cisco Aironet 1552E/1552EU are well equipped for municipal and campus deployments, video surveillance applications, mining environments, and data offload.

  • Enterprise MESH-Outdoor

    Has anyone used Enterprise Mesh in an outdoor application with 1242s.
    The plan would be to use 1242s inside buildings or in enclosures with external antennas.
    They are rated for high temps and humidty.
    All the Enterprise docs seem to only mention indoor applications.
    I think the 1242s and standard WLC would work, but would Cisco support it for Oudoors.

  • Cisco 802.11n Outdoor Access Point

    I have to propose to a client a 802.11n outdoor Acess point with external antenna, tha gain must be >8 dbi.
    Which cisco model should i use ?

    I have to propose to a client a 802.11n outdoor Acess point with external antenna, tha gain must be >8 dbi.
    DO NOT, under any circumstances, use 1260 or 3500e if you plan to use antennas > 6 dBi.  These two models DO NOT SUPPORT antenna gain higher than 6 dBi.  The only two 802.11n-capable WAP that can support high-gain antenna of > 6 dBi are the 1250 and the 3500p.
    Antenna Product Portfolio for Cisco Aironet 802.11n Access Points
    The 1250 is End-of-Sale (End-of-Sale Date:  12 January 2012) and requires 20.0w of PoE.  The 1250 can support antenna gain > 6 dBi.
    The 3500p was released around mid-2011 because people were howling/screaming about the lack of high-gain antenna support, thus the 3500p was developed alongside the AIR-ANT25137NP-R.
    Cisco recommends that the installation of the AIR-ANT25137NP-R should be done with proper sight-survey.

  • Aironet 1252 / 802.11n / Outdoor Use over 2.7 km (1.7 miles)

    Hi There,
    We are planning to use two Aironet's 1252 over an 2.7 km point to point link.
    One of the options we have it to install three HyperLink Parabolig Grid 5.8 MHz 27 dBi antennas in parallel for every 1252.
    I have some concerns because those antennas are not supported by Cisco. In fact, the most gain of Cisco supported antennas is 10 dBi Yagui for 2.4 GHz and 6 dB Omni for 5.8 GHz.
    The question is if the 3x 27 dBi antenna array on each side will work without self interferences and what would be the required separation of antennas to get 300 Mbps over the link.
    Has anyone tried something like this with the 1252's?
    Thanks in advance for any information.
    BR,
    Igor Sotelo.

    Hi Steve,
    I have seen the Q&A section for the Aironet 1250:
    http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps6973/ps8382/prod_qas0900aecd806b7c82_ps6973_Products_Q_and_A_Item.html
    states that both root and non-root bridge modes are supported.
    About that, may I ask if that means that the bridging can work over 802.11n, but is not supported for regulatory reasons. Or the bridging basically only functions in 802.11 a and g modes.
    Thanks for the information.
    BR,
    Igor Sotelo.

  • ASK THE EXPERTS - Update on 802.11n with Fred Niehaus

    Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to get an update on 802.11n with Cisco expert Fred Niehaus.

In addition to his participation in major deployments, Fred has served as technical editor for several Cisco Press books including the "Cisco 802.11 Wireless Networking Reference Guide" and "The Business Case for Enterprise-Class Wireless LANs." Prior to joining Cisco with the acquisition of Aironet, Fred was a support engineer for Telxon Corporation, supporting some of the very first wireless implementations for major corporate customers. Fred has been in the data communications and networking industry for more than 20 years and holds a Radio Amateur (Ham) License "N8CPI."

Remember that you can continue the conversation on the Other Mobility Subjects discussion forum shortly after the event. This event lasts through March 25, 2011. Visit this forum often to view responses to your questions and the questions of other community members.

    So there are two parts of this question, the latter part I cannot address as it is a future question.  Cisco does not comment on products that have not been released or on the strategy of next generation products.
    That said, Cisco was first to market with an 802.11n Access Point and well (we didn't all go on vacation after we did that)
    So let's talk a little about spatial streams in general and how it relates to what customers are doing today.
    The Cisco 1040, 1140, 1250, 1260 and 3500 Series Access Points are all two spatial streams (2SS).
    As of the time of this writing, a critical mass of 3SS and 4SS compatible clients have yet to be deployed, and the vast majority of WiFi clients that will be deployed over the next 18 months will be 1SS and 2SS clients.
    The higher SS clients are likely only show up in some higher end notebooks -- Why? well it is a given that smartphones and tablets are likely to continue to be 1SS and in some rare cases 2SS.
    This is because additional radios used in this technology consume battery life, add to the physical size of the device and increase the cost. Also many devices leverage the same single antenna for cellular as well as WiFi.  Therefore, it is my opinion that 3SS Access Points provide little if any performance benefit for smartphones or tablets in the enterprise today, and any real throughput gain is likely to occur with high end notebooks in close proximity to the Access Point and those are rolling out very slowly and we are monitoring this.
    Now we get to my favorite part of this..  I get to ask myself a question and then answer it..
    So Fred are you saying that there is no value in 3SS and 4SS?
    Of course not, 3SS performs similar to 2SS beyond a short distance, and with any multi-SS product RF interference must be addressed to capture the performance benefits of higher SS Access Points. Actual throughput in any WiFi environment is highly dependent on the presence of interferers and obstacles.
    Without the ability to mitigate the impact of interference, 3SS solutions will "downshift" to 2SS of 1SS and lose all the performance benefits anyway IMHO.
    I don't want to sound like a commercial, but you really do need Cisco cleanair technology in the AP and Cisco innovations deliver more and will go beyond the simple 3SS aspects of the 802.11n standard.
    IMHO it's more about CleanAir, good RF system design, and what we put into the AP with regard to performance "in the environment" and not what is on some spec sheet today.

  • Thinkpad Edge E535 only connecting at 72MBPS on 802.11n

    As I have a Thinkpad that supports 802.11n I purchased a Netgear WiFi router also capable of 300MBPS 802.11n expecting to get improved WiFi performance (over my existing 802.11g WiFi router). However it only connects at 72MBPS (and I'm less than 0.5m from the router).
    How do I enable the E535 to connect at the maximum router speed?

    Thanks for the reply Dennis.
    I probably should have given more details but the environment I am concerned with is an enterprise comprising hundreds of sites / tens of thousands of machines. Obviously any driver setting changes are not scalable across (pretty much any) enterprise environment. I would expect that scripting such changes would be a nightmare even on a single chipset, let alone many of them.
    I have a list of the almost 100 chipsets detected in our environment and so was planning to use this as the basis a script (not more than 10 of those chipsets would be 802.11n however). Of this 100, not more than 20 would be relevant to sites where this deployment it to take place. The script I am referring to would not change the band select of the driver (many drivers don't even seem to support it) but would detect the chipset and place the computer object in the correct OU, hence getting the relevant GPO and therefore SSID. I can't see a better solution than this at this point in time. Yes maintaining this would be a pain, but for the time being I see it as the best option.
    As you say, band steering is a very important feature but I can't see it steering 802.11a/g clients into the "preferred" band anytime soon but would love to hear otherwise. Preferred in this case, in most deployments where capacity is a major factor, is the 2.4 GHz band.
    Like you have mentioned, I have tested clients with a single SSID and the results were not pretty.
    My preferred solution is to prevent 802.11a clients on the 5 GHz radio by disabling all 802.11a rates. This obviously works to prevent 802.11b clients from connecting in 2.4 GHz so the same support would be nice at 5 GHz. I could then advertise the 2 x SSIDs in a GPO and the clients (should) connect correctly, with any luck. I have done this previously and it works with the 802.11n and 802.11g clients... just not the 802.11a clients.

    From the information above, my MBP doesn't access 802.11n network after install Mac OS X 10.6 Snow Leopard and all of updates.
    Snow Leopard changes Phy mode of 'Atheros 802.11n WL card' to 802.11g, and It works fine as 11n under 10.5.8 Leopard.
    What makes this situation?

    So by the virtue of my MacBook being compliant with the 802.11d standard I am open to these issues? And from the way you are explaining it it sounds like Apple is ahead of the curve with implementing 802.11d compliance?
    They're not ahead of the curve +per se+, but as an example many Windows XP machines are behind the curve if you will.
    Would it be legal to write an app or driver that you can set ignore certain problem country codes when you want it to? Because something like this would help my issue also rather than playing lotto each time I turn my MacBook on or wake it from sleep, hoping it will see my wireless network first.
    Unfortunately, I'm not a lawyer and not in Australia so I couldn't begin to guess at what is legal and what's not in this arena.
    However, there is no interface to the driver to be able to manually set a country code, so the point may be moot.
    I don't know what kisMAC can and cannot display, but the country code is broadcast within the 802.11 beacon frame and/or probe response frame if the frame's dot11MultiDomainCapabilityEnabled option is true, so you may want to try looking at its output of beacon frames.
    Three octets make up the country code - the two character country code and a third octet which is one of:
        * An ASCII space character (0x20) if the regulations under which the 802.11 station is operating encompass all environments in the country.
        * An ASCII ‘O’ character (0x4F) if the regulations under which the 802.11 station is operating are for an outdoor environment only.
        * An ASCII ‘I’ character (0x49) if the regulations under which the 802.11 station is operating are for an indoor environment only.
    The way the 802.11d standard specifies this all works is:
    9.9.1 Operation upon entering a regulatory domain
    A STA that is enabled for operation across regulatory domains shall default to passive scanning when it has lost connectivity with its ESS. Passive scanning is performed using only the receive capabilities of the station and is, thus, compatible with regulatory requirements. The timeout for determining the loss of connectivity is system dependent and beyond the scope of this standard.
    When a STA enters a regulatory domain, it shall passively scan to learn at least one valid channel, i.e., a channel upon which it detects IEEE Std 802.11 frames. The Beacon frame contains information on the country code, the maximum allowable transmit power, and the channels to be used for the regulatory domain. Optionally, the Beacon frame may also include, on a periodic basis, the regulatory information that would be returned in a Probe Response frame. Once the STA has acquired the information so that it is able to meet the transmit requirements of the regulatory domain, it shall transmit a Probe Request to an AP to gain the additional regulatory domain information contained in the Probe Response frame, unless the information was previously received in a Beacon fame. The STA then has sufficient information available to configure its PHY for operation in the regulatory domain.

    Note that this spec dates to 2001, so it's hardly something "new," just something that wasn't necessarily widely supported.

  • 802.11n: wireless APs configuration limited to 54Mbps

    Hi,
    I have been deploying a new wireless network using 5508 WLC (running 7.0.98) and 3502 APs.
    I followed the configuration guide found on:
    http://www.cisco.com/en/US/customer/products/ps6366/products_tech_note09186a0080a3443f.shtml
    When I try to chek my access-points, maximum speed supported seems to be 54Mbps.
    Testing the same client on a standalone AP configured for 802.11n shows 144 Mbps.
    Any hint?
    TIA

    Solved.
    WMM was not enabled.

  • Suggested 802.11n/ac minimum data rates

    Good evening,
    We presently have some minimum data rates setup for our 802.11 deployment (.11b/g disabled below 9Mbps, required at 11Mbps and supported at 12Mbps+ and for .11a/n/ac  below 12Mbps disabled, 12Mbps required 12+Mbps supported).  Currently in the high throughput section all MCS indices are supported.  Are there are recommendations on the .11n/ac minimum supported MCS index?
    We are supporting both 1142 and 2702 access points.
    Thanks!

    You should disable upto 11  Mbps  (including 11 Mbps) & make 12 Mbps mandatory in 2.4GHz band. This will stop performance degradation due to protection mechanism enable when 802.11b client present in the network. (if you still have to support 802.11b legacy clinets then you cannot do this) 
    Are there are recommendations on the .11n/ac minimum supported MCS index?
    leave all MCS indexes enabled. Depend on the RSSI & SNR, it will dynamically set a suitable rate. Refer this for detail

  • AEBS 802.11n 5GHz gives "invalid password" - need a solution!

    After an update to 7.2.1 I've been trying for the past 4 hours to get back on my 5GHz network, but no success. I hope someone can resolve this, because it's getting extremely annoying.
    - 802.11n (b/g compatible) 2.4GHz, pass or no pass -> works
    - 802.11n only 2.4GHz, pass or no pass -> works
    - 802.11n 5GHz, no password -> works
    - 802.11n 5GHz, WPA2 Personal pass -> invalid password
    I tried everyting. First setting it to b/g compatible at 2.4GHz (when it works in Leopard), then to 5GHz -> invalid password. Added it to my preferred networks, hard reset of the AEBS, downgrade to 7.1.1 and a hard reset, new names for the networks, different passwords, deleted everything from the keychain to avoid any mixups, countless reboots...
    No results. I just cannot connect to a 5GHz network, because Leopard claims the password is invalid.
    I have no clue what to do next. It worked fine until I upgraded to 7.2.1, and now even when I downgraded to 7.1.1, it still won't work. And 5GHz works fine without a password. But as soon as you set a WPA2 Personal (this or WPA2 Enterprise, which I don't want), Leopard says invalid password.
    I also noticed that when I setup a preferred network in Leopard, and insert a WPA2 Personal password, it changes it to simple WPA, without the 2, when I save it. Although this is strange, it shouldn't matter. Because when I setup a 802.11n 2.4GHz instead of 5GHz network with a WPA2 Personal password, it works great with my WPA(no 2)-preferred-network settings.
    I'm completely lost here. Who can help me out?
    (Just a tip: do not, I repeat, do not ! update to 7.2.1).

    Hi guys. "Good" to know we're not the only ones. I reported it also, let's hope an update follows soon.
    I still don't know where the problem lies exactly. Mainly because it did work for me in Leopard, after I did a completely clean install last friday. It just picked up the network and it worked. I tried 7.0, 7.1, 7.1.1 and 7.2.1 about 5 times each now. All along with complete hard resets, powerdowns and all the possible settings I could think of, nothing works. First I'd say it's probably the AE firmware, but since nothing works anymore, I'm leaning towards Leopard now...
    Maybe the password isn't being sent correctly to the AE, or the respons of the AE doesn't get received properly. There already was a Keychain update right after the release, maybe there are still more updates in that area, and they'll be included with the next big update.
    If anyone finds a way to fix it, let us know! I'll keep trying, although I don't think it'll do much good

  • Need Help with extending Airport Extreme w/802.11n

    I would like to find a way, if there is one, to extend the coverage of my Airport Extreme w/802.11n. My object is to be able to share my home network with a 2nd house on my property which is approx. 90-100' away from main house and Airport Extreme w/802.11n base station. This home base station is connected to my iMac and I would like to extend it to allow my Dell PC w/ Win XP in 2nd house to connect to the internet/share files/share printer.
    Is this possible and what would I need on the PC side to accomplish this wirelessly?
    Thank You in advance for your help.
    Daniel

    Is the 2nd house on a the same electrical box as the main house? If it's the same, then you can try the powerline ethernet solution.

    You will find it cheaper than most outdoor point-to-point bridge solutions.
