Bridge Point to Point with AP 1552EU - Maximun Data Rate

Hi all, I have a question for you, and I need your help.!!!
I have two site (Central and Remote) and I did a link point to point between it. These AP are managed by a WLC 5508, the distance between this AP is 30 Mts or 98 feed, I have configured the channel width in 40Mhz in the WLC, and MCS-5 in the data rate sección of Bridge AP.  I did tests flooding the link and I only can transfer 40Mbps in both directions at the same time. This ap model is 802.11n capable. So how can I increase the data rate from 40Mbps to 100 o more Mbps.?
The antennas are directional with two ports (TX/RX) and are connected in the ports 1 and 3 of AP.
I hope your response.
Thanks,

Wow.  You're radios are only 100 feet apart and you have 14dBi directional panels hooked up to them?  Hopefully the TX power is configured properly and is turned *way* down.
You should certainly be able to get 802.11n HT rates between two 1550s with these antennas and 2 spatial streams.  You *should* be able to achieve HT MCS 15 at 40MHz with a PHY data rate of 300 Mbps.  Actual Layer 3 throughput would be approaching 100Mbps, but I think you are more likely to see ~80Mbps in actuality.
Best of luck!

  • Bridge 1300 building to building link for VOIP Data Rates settings and QoS

    Hi,
    What are the recomendations for data rates settings of wlan fo using voip in a link building to building.
    Default is

    OFDM is a physical layer encoding technology for transmitting signals through the RF. This method breaks one high-speed data carrier into several lower-speed carriers that transmit in parallel across the particular RF spectrum. OFDM, when used with various modulation types such as 802.11g and 802.11a, is capable of supporting data rates as high as 54 Mbps.

  • How do you mark your 'in' point with the keyboard?

    I know you can mark the first frame of your selection by hitting the mouse button but I find I press the spacebar to start previewing the source footage and stop the playhead at just the right point where my 'in' should be. Now as soon as I move the mouse the playhead jumps to a different part of the clip, this results in me losing my 'in' point.
    What I want to do is hit the spacebar to stop at just the right point, hit a key to mark my selection, hit spacebar to resume playing and then finally hit shift-A to mark my out. Any ideas?
    Thanks,
    Dave

    Could you describe your workflow in producing Quicknotes. 
    Basically I use a screen/system audio capture application to capture what I am doing in an application along with any audio being produced. There are many such applications available, but I tend to stick with Snapz Pro X which I have been using for years. My somewhat old PPC G5 limits me to captures of about 960x540 at 24 fps. This step, of course takes place in "real time." With iMovie '08, I would had to transcode the captured data to compatible compression formats, but with iMovie '09 it looks like I can go back to using the default Animation video codec which I prefer.
    Once the screen captured data is stored to a file, I bring it into iMovie for a quick edit -- usually just a quick trimming of the length, adding a title, and adding simple opening/closing cross-fades. When done, I output the edited content via the "Export Using QuickTime" option -- normally as AIC/AIFF but will likely try Animation/AIFF on my next one. The editing process takes only a few minutes but exporting adds additional time.
    At this point I import the edited file to GarageBand for a quick voiceover. I use this approach so I can keep a copy of the iMovie exported file for reuse at some later time. (My original intention was to eventually go back and correct my voiceover mistakes but I never seem to get around to doing this as some new project is always coming up.) For this step I generally use a Blu "Snowball" USB mic. In any case, the voiceover is also in real time. I normally export the finished file using the "Full Quality" mode so as to avoid a further transcoding of the video track. (It also saves time if no video re-compression has to be performed.)
    At this point it is merely a matter of targeting my final output. For my web content, I usually use MPEG Streamclip to convert the GarageBand file to an H.264/AAC file with a targeted video data rate of 1.0 Mbps. If I decide to post the file in an MOV file container, I then open the file in QT Pro and set the "poster frame" for iWeb use. If for any reason I wish to preserve the MP4 container, I use iTunes to "poster frame" the file.
    As previously implied, I use iWeb to actually post the file. In this case, the tutorials are posted to a separate "Podcast" page collection since the are easy to maintain; allow user comments, RSS notifications (which I've never tested), and searches (also untested). Primarily I liked the ease with which I can duplicate a previously posted video entry and simply drop in the new clip and modify the text changes. Posting the update is, of course, as simple as pressing an icon button and waiting got the upload to finish.
    I have completed the work flow in as little as an hour but my average is closer to 90-120 minutes since my wife and/or pets usually want some sort of attention during the process. You may have noted Gracie (a Congo African Grey) or Mango (an Amazon Orange Wing) in the background of some of my voiceovers. And that, as they say, is all there is...
    You should really consider posting these on YouTube.
    Not really something I ever wanted to do. I have my own MobileMe account, most viewers I'd want to reach are Mac owners and users, so I am not really interested in reaching out to the "world at large."

  • Data rate of AAC file converted with iTunes 7.5.0.20

    I have just noticed data rate of files converted to AAC with iTunes revision 7.5.0.20 deviate slightly from preset converting data rate in random manner. For example browser shows files with preset 192kBit/s data rate as 193 or 195kBit/s data rate, ones with 320kBit/s preset as 321, 322, 325kBit/s etc.
    Is this a encoder bug or a music content dependent data rate adjustment?
    Anyone a suggestion?
    Thanks and best regards

  • How can I set up a guest access point with a Time Capsule and an Airport Extreme? I am using a Telus router with the Time Capsule used as a wireless access point (bridge mode). I don't want the guest access point to have access to my network.

    How can I set up a guest access point with a Time Capsule and an Airport Extreme? I am using a Telus router with the Time Capsule used as a wireless access point (bridge mode). I don't want the guest access point to have access to my network.

    The Guest Network function of the Time Capsule and AirPort Extreme cannot be enabled when the device is in Bridge Mode. Unfortunately, with another router...the Telus...upstream on your network, Bridge Mode is indicated as the correct setting for all other routers on the network.
    If you can replace the Telus gateway with a simple modem (that performs no routing functions), you should be able to configure either the Time Capsule or the AirPort Extreme....whichever is connected to the modem....to provide a Guest Network.

  • Is there any way I can control which specific access point I connect (and stay connected) to from amongst a set of access points with the same SSID?

    I'm working from a boat in a harbor in which the ISP has deployed numerous access points around the periphery.  All the access points share the same SSID and each is configured to use either channel 1, 6 or 11.   From my location, there are over a dozen of these access points "visible" (based on the the output of WiFi Scanner) with a range of RSSI and S/N values that vary over time.
    The ISP has told me that the quality of my connection should be "perfectly fine" for any access point with an RSSI value better than -75, but I know from experience that my connection quality is miserable (i.e. < 50Kbps download) for almost all of these, including those with RSSI values better than -75.  There is at least one exception, however, which gives me on the order of 2Mbps download, which is "great" in this context.
    I've tried using a more powerful USB antenna plugged into my MacBook Air (mid 2011), but as far as I can tell, it really doesn't make much difference.  Neither does my location within the boat.   The overriding factor seems to be which access point I happen to connect up to.
    I should point out that the closest access points are about 75 yards away, with many of them being several hundred yards away or more.  I'm guessing that even though the signal strength of some of the distant access points is causing them to get "chosen" some times, the results are unacceptable due to the distance.
    I'm hoping that I can determine, through experimentation, which access point(s) provide(s) acceptable performance and then configure my Mac to limit my connection to those points through whatever mechanism I need to use (e.g. channel, MAC id, etc.).

    Establishing a wireless connection with a client computer is left to the access point for various reasons. One reason that your Mac may not connect to the strongest access point is that it may have reached a limit of the number of clients it can serve, leaving it unable to accept a connection with another. The limit may not be very large.
    Suppose that happens, and your Mac establishes a connection with a more distant access point having a weaker signal. Then, suppose a client drops off the network. Doesn't this mean your Mac will switch to the stronger access point? Not necessarily. The throughput delivered to and from your Mac would have to drop below a threshold specified in the AP for it to drop the client, leaving your Mac free to connect with another one. The reason for this is to prevent rapid switching from one AP to another in an area in which two signals are of approximately equal quality. If that were to occur the frequent and repetitive handshaking between the two devices would slow throughput to zero.
    In an environment in which several access points are broadcasting the same SSID, Apple provides no insight as to how it determines which access point to choose. This is the reason I suspect this "choice" is a function of the router, or access point. The connection originates with it, not the Mac.
    Now, what would solve your dilemma would be to determine a way to control the access point with which your Mac connects, by specifying the access point's unique MAC address for example. In this happy circumstance, you could maintain an editable "whitelist" or "blacklist" of the harbor's access points and be able to choose which among them you prefer.
    I do not believe OS X maintains such a record of MAC addresses though, only those of the routers it uses. If I am correct about that, such a solution is unlikely to exist. Don't let that discourage you from searching for one though... I would concentrate on something like "selecting access point by specific MAC address".
    I did find this patent application though:
    Roaming Network Stations Using A Mac Address Identifier To Select New Access Point
    Perhaps it's a start

  • Wi-Fi Access Point with B Channel or Wi-Fi with B Channel

    What does Wi- Fi with B channel or Wi-Fi Access point with B Channel mean. Can someone explain me. I am confused

    I don't know what your asking.  if your talking about 802.11b, that is a standard and you can compare the difference of 802.11b, 802.11a, 802.11g, 802.11n and or 802.11ac. Wireless devices, that means client devices have to be able to support the standard that the access point is using.  So if an access point is 802.11b only, the wireless client device has to be able to support 802.11b.  If for example, the access point is 802.11b/g/a/n/ac, that means the client has to be able to support at least one of those standards to be able to connect.
    Just take a look at the standards,  here is a link to a quick comparison.

  • Create waveform from a set of points with differtent time intervals

    Hello,
    I would like to create a waveform from a set of points like this
    Time           Data
    0                 0
    0,5              1
    0,6              2
    1                 1
    2                 0
    5                 1
    The problem is that the time interval between each points are not the same.
    The only idea I found was to create a waveform for each doublet of points with the same rate (100ms) and than to append them together.
    Does anybody have a better idea?
    Regards,
    Risotto.

    If you use a Wave From data type, re-sampling is not required.
    When using a WF datatype the chart (graph) will pick-up the X value from the t0 of the waveform.
    The trick is to just build an array of the single update value and make sure the t0 value is correct.
    Re-create this example
    and try it for yourself.
    Ben
    Note: make sure the data you pass is consistant with the data already displayed. If you post a t0 value that is older than what is already displayed, the chart will clear the display and start over.

    Another option is to temporarily change your view to outline mode, when your done switch back to preview mode. Ctrl-Y or View>Outline {View>Preview} The menu option will change depending on which mode you are in.
    And another option, double click on the object in question to place it in Isolation mode. You can now edit to your hearts content. When done, click on the gray border at top of document.
    So as you can see there are multiple ways of accomplishing the same thing.

  • How to play a cue point with mixer

    I know how to play a cue point of sound with the method:

    I need to have any hint about this because I must use both cue

    1) I can't use "playrate" with  "sound(1).play()" method.
    With this method I can use cue point;
    2) I'm trying to know If I can use cue point with   mixer method.
    With this method I can use "playrate" .
    It is also for me important to know if it is possible or

    iPhone 3gs, 4 or 4s?
    With the former two, just drag the videos to the desktop iTunes and sycnhronize to your iPad. They will be synched to the stock Videos.
    With the latter, you can either resize the video to 720p (or less) OR use a third-party app (It's Playing, AVPlayerHD, GoodPlayer being the best choices) to play it back. I'd go with the latter to avoid quality degradation and long-lasting reencodings.

  • Cfchart CFmx8 charting points with no data

    We are having a problem with <cfchart> in CF 8. It
    worked fine in CF7.02 with all hotfixes installed. Basically it
    plots points where there is no data. some lines have data for 15
    points and some for maybe only 13 or 14 points. It fills in teh
    missing points with data from the last point that had data.
    Notice the last three lines on this chart. At the end of the
    line--- where the line goes straight across it is charting data
    that doesn't exist.
    http://www.bikersites.com/SL/raceSL/secondsbehind.cfm?RHID=31:1
    This gets to be a real problem when you look at the following
    chart. It gives the races lap times for laps they never completed.
    http://www.bikersites.com/SL/raceSL/laptimes.cfm?RHID=31:1
    Any ideas? Anyone else having this problem?
    This works fine on our development server which had CF7. But
    at hostmysite they have cf8.

    Having same problem here, with CF9.  I have 5 monthly data points for Jan-May 2012.  But CFCHART will extend the LINE in the line chart for the June - December 2012 with all ZEROs.  This only happens when I'm plotting multiple series, for example if I add a CFCHARTSERIES for all 12 months in 2011. 
    If I remove 2011, CFCHART only displays the 5 monthly data points for 2012.  I'm using two CFQUERIES (Q of Q), one with 12 monthly data points for 2011, and one with 5 data points for 2012 year-to-date.  Individually (with 1 CFCHARTSERIES) they plot fine.  But when you have TWO CFCHARTSERIES, the 2012 extends the 2012 line with all ZEROs for June-Dec 2012.  So you don't get a good year-over-year chart, and I need one that scales, since all the values are between 90% and 100%.  Thanks for any help/advice.

  • Mimo access points with Static WEP security do not allow connection speeds above 54mbps

    I am getting this message:
    Access Connections - Mimo access points with Static WEP security do not allow connection speeds above 54mbps
    If I switch from WEP to WAP i do not get the message but I still only get 54mbps speed.  I have a Linksys Wireless-N Broadband Router.  Is there a setting that I am missing???

    Yes you need to use WPA-AES or WPA2-AES, or no encryption, to go faster than 54Mbps. This is part of the 802.11n spec.
    That's not so bad, because if you have the right 802.11n card and use the right settings you can go up to 300Mbps!
    What bites is that the 802.11n card which comes with X-Series ThinkPads is the Intel 4965AGN. It does not support the broader 802.11n 40MHz channel width option, limiting the top speed to 130Mbps .
    The new ThinkPads based on the Montevina/Centrino 2 platform will most likely use the Intel WiFi Link 5100/5300 802.11n/WiMax cards, which I hope will fix this, coz I'm going to buy one!

  • Can pulse measurement.vi measures 2M points with 10ns time interval?

    Hi,
    I used pulse measurement.vi to measure the pulse duration of waveforms when the waveforms exceed certain threshold level. The data file has 2 millions data points with 10ns time interval.  But I got error message saying that
    "The waveform did not cross the mid reference level enough time to perform this measurement. Check the signal length, mid reference level, and reference level unit."
    I was wondering if pulse measurement.vi is capable of handling such large file or it was due to my paramenter errors.
    Thank you for your help in advance.

    I realized that I can't really modify the percent level settings or specfication of the pulse measurement.vi. For instance, I changed the percent level setting to peak instead of the default auto select. After running the VI unsuccessfully and I reopened the pulse measurement.vi, I saw the percent level setting was set to auto select again instead of peak method. I have attached the image of the block digram and a very small part of the waveform data. I hope you can open both.
    Thank you.
