Omnidirectional antenna pattern and position

I have a number of internal AP models (3502i, 3602i, 3702i). I understand that they all have inbuilt omni-direction antennas (creates a 360 degree coverage pattern). My question is - does it matter which position the AP mounted? Does it makes any difference (coverage wise if I mount the ap horizontally or vertically? or the signal radiate to the same area no matter which position I mount the AP? Any feedback, reference or links would be greatly appreciated.

When mounting an access point on a horizontal or vertical surface, you must ensure that the access point is oriented with the LED indicators pointing down .This positioning allows the LEDs to be visible to someone on the ground below the access point.
You must also ensure the access point is mounted with the hinged access cover facing out.
Note : Omnidirectional antennas are vertically polarized and should be mounted vertically with the antennas facing down.

  • Help Creating an Antenna Pattern from Multiple Files

    Hello, I would like some suggestions on how to create a 3-D plot from mulitple data files. In my setup I measure a receive antenna using an HP 8510. The transmitter is stationary but the receive antenna is able to be positioned at different angles. For each angle we sweep the receive antenna in the azimuth axis. So for each azimuth sweep I generate a data file,  and each new sweep I roll the antenna in the phi direction. I would like some suggestions on how I would write an application where the user could select the multiple data files and then plot the data in a 3-D plot generating an antenna pattern or some call a volumetric plot.
    Thanks,
    joe

    Hi Joe,
        Attached are three vi's to get started with. AzElAntennaPattern generates a dipole antenna pattern (r = sin(theta)) in radius, elevation (theta), azimuth (phi) coordinates. It transforms the coordinates to Cartesian and puts every azimuth sweep into a new row in an array. This creates 3x 2D arrays, one for X, Y and Z, each row an azimuth sweep. These can then be plotted in a 3D parametric graph. Technically the parametric graph accepts spherical coordinates, but it won't draw axes or grids in spherical as far as I can tell. I'm sure it uses the normal spherical coordinates anyway, so best to transform to Cartesian yourself. DipoleWrite, generates azimuth sweep files and puts them into a folder you choose. Choose the folder by pressing the small folder icon before running it. AzElAntennaPatternFromFolder, shows how to read these files back in and plot them. If you post one of your files, I can help with a file reader.
    Good luck!

  • Hibernate, DAO pattern and tree hierarchy

    Hi all,
    I use Hibernate for a short period of time and now I'm facing a complex problem . I try figure it out what is the best practice for the following scenario:
    I have the following classes: Department, Team, Position, all of them inherited from a Entity class even there is almost no difference between them. But I wanted different classes for different entities.
    I try to create a tree hierachy, each object is with all others in a bidirectional one-to-many relationship. For example a Department can have Teams and Positions as children and a Position can have Departments and Teams as children.
    I created the mapping files and I don't know how to create all necessary methods without duplicating the code.
    Questions:
    1. Do I need a DAO pattern implemented for this design?
    2. Can you recomend some documentation or ideas that will help me find out what is the best approach in this case?
    Thanks

    Write the DAO for the class that is the root of the tree. Sounds like it should be DepartmentDao.
    I don't know of much better documentation than the Hibernate docs. Check their forum, too.

  • Object Size and Position values not being retained

    Hi,
           I'm trying to set the size and position of a picture object in a report. This logo, should appear on the top right corner of the report.
    The margins of the report are Left - .79 in, Right - 0.79 in, Top - 0.79 in and Bottom - 0.39 in.
    The size of the picture object should be 1.574 x 0.79 inches.
    I have ensured that File -> Page Setup -> dimensions are in INCHES.
    I right click the logo and select 'Size and Position'.
    I set 'Y' (distance between top of object and top margin) = 0. This is to perfectly align the object with the top margin.
    Now, i set the height of the object = 0.79 inches. Ok the dialog and close.
    The strange thing happening is, when i re-open the size and position dialog, i see that the values i set are not being retained.
    0.79 becomes 0.810
    and
    0 become -0.010.
    What am i doing wrong here? How can i make sure the values i specify in the size and position dialog are  retained.
    Thanks.

    Ensure File | Options | Layout tab has the following UNMARKED!!!!

      Guidelines
      Grid
    Ensure that "Snap to Grid" is turned off.
    Make your grid size larger (.5 inches for example)
    What is occurring (I suspect) is that your objects are snapping to the grid - thus changing the position and possibly size due to the Snap to Grid being turned on.

  • Can you change the units used for size and position in layout editor?

    Hello,
    In Aperture 3.4, does anyone know if you can change the units used for size and position in layout editor?  The page is set in inches, but the image size and position are given in centimetres and I would prefer to work all in inches to create custom layouts.  I can't see any way to change this.  If anyone knows how it would be much appreciated.  Thanks!

    Aperture uses the unit settings defined in the System Preferences.  Set the "Measurement Units" in the "Region" tab of the "Language & Text" preferences to "US"; the Aperture will display the Size & Position in inches, if it is the "Book" layout manager you are asking about.
    Merry Christmas!

  • Is there a way to remove the size and position readout when moving Lines in Keynote?

    When moving the endpoints of lines while creating a presentation, a size and position readout appears on the screen. This obscures details below it, often making it difficult to precisely position a line. Is there a way of disabling this? The option in Preferences for disabling this readout for objects does not work for lines. Is this a bug, or am I missing something?

  • Error while assigning the user to orgunit and position

    Hi,
    We are having the below issue :
    1.       Obtain the HR master record (P Ids) created by interface - ECC
    2.       Assign a valid user to this HR master record -ECC
    3.       Do the position/Org assignment against this P Id or personnel master record - ECC
    4.       Transfer the Org Id, then the position ID and then the personnel master ID (P Id) to SRM u2013 ECC
    5.       Check if the user is in SYNC in SRM  - Ideally he should inherit the mandatory parameters from the above Orgs in the structure without which he shall not be able to shop in SRM u2013 step executed in SRM
    Please let us know if this process is as per the expectation.
    If so, we are ending up with error in the third step where the assignment is not allowed since the personnel master record is created with prior date than the position and the Org units.
    Actually we are getting the idoc with user alone from other system, org and position ids are blank. So we are assigning the user in the system and we are getting above error.
    Is this the correct process to bring the users alone into the system and doing the position/organization assignment in ECC now?
    Or the Idoc comes with this data as well? 
    Regards
    Venkatesh P
    Edited by: Venkatesh Padarti on Mar 5, 2012 5:33 AM

    Thank you vikas for your reply.
    So we should bring all the data in the idoc(O,S,P). Even though O, S are present in the receiving sytem?

  • Creating a new job and position prompts customizing request...

    Dear All,
            I created a Job and Position through PP01 transaction. I am facing 2 issues while doing so...
    1. System prompts for Customizing request when i try to save the new entry.
        What table/settings do i need to maintain for turning of the customizing request promptings.
    2. Once i save the entries(after entering some dummy customizing requests), when i check the
        HRP1000 table for the new jobs and positions... The table entry shows 2 records for each Job and     
        position. One entry with Plan version '.:' and another with active Plan version '1'.
        I need to have just one entry in HRP1000 table for each job/position with ACTIVE plan version.
       I checked T77S0 table, it has active plan version maintained against the PLOGI-PLOGI entry.
       Please let me know what table i need to maintain to handle my requirement.
    Regards
    Nanda

    Hi Nanda,
    When you create new job or position in sandbox system it will not ask for the request number,since you generally dont transport the objects from sandbox to test system.
    When you create a new job or position in development system, it will always ask for request number. This is because, in most of the cases, you need to transport the job and position to test system and then to production system.
    Without a customizing request  you wont be able to transport those changes to next system.
    Thanks,
    Supriya.

  • Object Oriented Patterns and Visio

    Visio question:
    Does anyone know if there are established shapes for each (or any) of the object oriented patterns? If not, is anyone working on that or interested in that?
    Since they all have names (Momento, Proxy, Iterator, Mediator, Observer, etc.) it seems like they ought to each have their own shape. Since Object Oriented is all about communication of intent, each pattern having its own recognizable shape would go a long way toward a more meaningful communication through diagram. Also, if they each had their own shape, then the super-patterns (based on commonly grouped patterns and interactions) could also be easily represented.
    Blaine

    I'm kind of making an assumption here and if it's in error then feel free to disregard the rest of this post.
    Assumption that you're thinking terms of shapes for representing in UML the various patterns. Everything you need is right there in front of you already regardless of whether you use Visio, Rational, Poseidon or some other UML tool.
    Patterns are not individual constructs. One does not make a Mediator class. One makes a Java class that is an implementation of the Mediator pattern. As such you would see in the static class diagram the same grouping of classes for an X Mediator as you would for Y Mediator. That is the image you're looking for. It's not a single widget that you drag onto the screen, it's in the pattern itself.
    If, however, you're talking about something like a graphical representation to give to managers that says "Here be Momento patterns", then I would postulate that you're trying to communicate information that they don't need nor should they concern themselves with. Patterns are an implementation issue. They deal with, "How" we will solve a problem, not what problem will we solve. Mangaers, IMNSHO, need only concern themselves with what problems we will solve, not how they will be solved.
    Just my 2 krupplenicks on the subject, your milage may of course vary.

  • I've recently messed up my Mac OS X Lion by deleting Aperture, but I need to get my data out of the computer. And by the way, I've got an important project in Final Cut Pro X. Is there any way I can back it up (including fxs and positions of the clip) ?

    Hello everyone
    I've recently messed up my Mac OS X Lion by deleting Aperture, but I need to get my data out of the computer. I've tried to repair it using DU, but it said I needed to backup all my data and reinstall the OS. How do I backup my data to an external drive?
    And by the way, I've got an important project in Final Cut Pro X. Is there any way I can back it up (including fxs and positions of the clip) ?
    Hope you guys can help me!

    You need to back up 2 folders, Final Cut Events and Final Cut Projects which by default are located on your Movies Folder. You can always check by clicking on a clip inside Fianl Cut X and selecting Show in Finder in the contextual menu for the selected clip.

  • Extending the End Date of Relationship Org. Unit and Position

    Hi All,
    Please help me below.
    Problem: The end date for the relationship between org. unit and position should be set back to 31.12.9999. It was accidentally been set to 31.03.9999 and results to two records in infotype 0001, which the wrong record should be deleted.
    This can only be deleted by changing the relationship end date in PO13 but unfortunately, the user doesn't have any access to this transaction.
    Request: Can you explain to me on how the end date can be change in transaction PPOME or PPOM_OLD as these are the only transactions the user has an access. I'd already explored these transactions but I can't find on how it should be deleted here.
    Thanks!

    Hi Raju,
    Thanks for this information. This was a very helpful answer. But I only need to extend the end date of a particular infotype 0001 record of a particular employee. I think the report will extend all of the records of all the employees in the system. I can't find any parameter in the report wherein I can set the employee number I wish to extend the end date.
    Thanks!

  • Aarrrghh - can't find image size and position in captivate 8!

    I was using Captivate 8 and it was under a tab in properties (don't remember the name of the "sub-tab").
    Now, I'm using a newly downloaded version and cannot find size and position (x, y, width, length, etc.).
    This should NOT be so hard
    Any suggestions?

    Totally agree, don't like the UI change neither. One of the reasons I'm happy to know all moving and resizing shortcuts by heart, they still work in CP8. But wouldn't it be wonderful to have rulers?
    Shortcut Keys: Moving and Resizing Objects - Captivate blog
    It is not as simple neither, because it is in a different location for a normal and for a responsive project.
    For the normal project it is under the Options tab, for responsive projects you need the Position panel, both for Size and Location.
