Create Hot Spot with multiple APX

I have many APX units (802.11g versions) providing individual coverage for corridors in an office building. I would like users to see a single hot spot (or at least fewer hot spots) that utilize multiple nodes. All APXs are ethernet connected (static addresses, same network) and currently 'create' multiple individual wireless networks. As long as users stay in one place it's not a problem, but they cannot move about without necessitating a change from hot spot to hot spot. WDS seems to revolve around avoiding the ethernet connectivity which I absolutely want to keep. Every definition I find on the discussions about 'extending' the wireless network seems to revolve around an APX being a client of a wireless network while providing wireless access at the same time. What I'm hoping to do is to have additional APX units 'bridge' a common ethernet network while presenting a single WiFi network that maintains connectivity if users roam to another part of the facility. Anybody pulled this off? Tips? Pointers?
Thanks,
Greg

Unless I'm missing something, it seems you want to create a "roaming network". Read about it in page 42 of Apple AirPort Networks.
You are correct... do NOT confuse a roaming network with "extending" a network, or creating a WDS. A roaming network is infinitely preferable to those alternatives.
Each Express must be configured to use the *exact same network name and security.* Users will be able to wander about the office and will enjoy seamless connections without having to join a different network. There are only minor caveats... if you're listening to an iTunes radio station for instance, streaming will stop as you go from one node to another.
In a roaming network, the Expresses will use different wireless channels. There are only three non-overlapping channels available in a "g" network. That's not as bad as it seems, though. For instance, if you've configured them to choose their wireless channels "automatically", one Express may choose Channel 1, a second Express will choose Channel 11, and a third will choose Channel 6. By the time you add a fourth Express, ideally it will be sufficiently distant from the first so it can choose Channel 1 again.
When you get them all configured, you may wish to manipulate their multicast rate to optimize your network's performance. Why? If one Express remains within range of a client as it moves away from it and closer to another, it may still be connected to the first Express even though its signal is relatively weak. Multicast rate is designed to address that problem.
Transmitter power is another parameter you can adjust in the event an Express's range is too great and you want to distribute the workload - an Express has a limit of ten wireless clients.

  • Creating Hot Spots in DPS

    I have a spot where I would like the same position to have both the open and the close button.
    For example, an image with a little “+” icon : when you tap the “+” icon, a box opens up with information, and the “+” icon changes to an “x” icon (the “x” is in the exact same place as the “+” was before)
    The image with the “+” icon is one state, the second state shows the information with the “x” icon – I would like it so that when you click on this “x” it brings you back to the first state.
    I know it can be done because I have seen it used in other digital magazine publications (for example, in Vanity Fair magazine)
    Can anyone explain me how to do it step-by-step? Tutorial link also be very helpful.
    Thnx.

    There are tutorials for creating hot spots and toggle buttons in DPS Tips > Advanced Overlays. Example:

  • How to create list items with multiple attachment files using rest api javascript

    In one of user form I am using javascript rest api to create a list item with multiple attachment files. So far I am able to create list item and once created uploading an attachment file. But this is two step process first create an item and then upload
    a file.
    It create an additional version of the item which is not desired. Also I am not able find a way to attach multiple files in a go. Following is the code I am using.
    createitem.executeAsync({
                    url: "/_api/web/lists/GetByTitle('UserForm')/items(1)/AttachmentFiles/add(FileName='" + aFile.name + "')",
                    method: "POST",
                    contentType: "application/json;odata=verbose",
                    headers: {
                        "Accept": "application/json;odata=verbose",
                        "X-RequestDigest": $("#__REQUESTDIGEST").val()
                    binaryStringRequestBody: true,
                    body: fileContent,
                    success: fnsuccess,
                    error: fnerror
    So somehow I need to combine item attributes along with attachment files in body: param. I visited https://msdn.microsoft.com/en-us/library/office/dn531433.aspx#bk_ListItem but no success.
    Appreciate any help.

    Thanks Mahesh for the reply and post you share it was useful.
    But this does not solve the core of the issue. You are uploading attachments after creation of item and multiple files are being attached in loop. This is kind of iterative update to an existing item with attachments. This will end up creating multiple versions. 
    What I am trying to achieve is to create an item along with multiple attachments in a go. No item updates further to attach a file.
    Please suggest how this can be done in one go. SharePoint does it when one creates an item with multiple attachment.
    Thanks for your reply.

  • How to create a table with multiple select on???

    Hi all,
            I am  new to webdynpro and my requirement is to create a  table with multiple selection on.I have to add abt 10 rows in the table but only 5 rows should be visible and moreover a verticalscroll should be available to view other rows.Can anybody explain me in detail how to do that.Please reply as if you are explaining  to a newcomer.Reply ASAP as i have to do it today.
                                                                           Thanxs

    Hi,
    1. Create a value node in your context name Table and set its cardinality to 0:n
    2. Create 2 value attributes within the Table node name value1 and value2
    3. Goto Outline view> Right click on TransparentUIContainer>Apply Template> Select Table>mark the node Table and it's attributes.
    you have created a table and binded its value to context
    Table UI properties
    4.Set Selection Mode to Multi
    5.Set Visible Row Count to 5
    6.ScrollableColCount to 5
    In your implemetaion, you can add values to table as follow:
    IPrivate<viewname>.ITableElement ele = wdContext.nodeTable().createTableElement();
    ele.setValue1(<value>);
    ele.setValue2(<value>);
    wdContext.nodeTable().addElement(ele);
    The above code will allow you to add elements to your table node.

  • Is it possible to create a form with multiple form fields on a single line?

    Is it possible to create a form with multiple form fields on a single line?  I can't find anything in the documentation or a template that does this.
    I am trying to create a "documents received" checklist with a check box on the left margin, a date-received field to the right of the check box and and a description of the document (Formatted Text) on the far right.
    In the past I have entered the Fixed Text with a word processor, published it to a PDF file, then added the check box and date fields with the Acrobat Forms editor.  I would prefer to use FormsCentral if it is possible.

    We now support multiple fields on one line. This post provides a brief overview.
    Give it a try and send us your feedback.
    Sorry it took so long.

  • I need your expert opinion on how to create a map with multiple conditions.

    Hello.
    I need your expert opinion on how to create a map with multiple conditions.
    I have a procedure (which i cannot import or re-create in OWB due to the bug), so i am trying to create a map instead :-(
    How can i create a cursors within the map?
    My function creates table and cursor.
    Then it will have to check for duplicates in the tables (the one created and another table) - the criteria for finding duplicates is a number of fields.I then need to place few different conditions (if some attributes are not available) and it has to load cursor based on this conditions. The next step is to fetch the data into the cursor based on what attributes are missing.
    The next thing it will do is insert the data into table (if record doesn't exist), output the error in separate table is record is corrupted, or update the record with changed information.
    In short i need to re-create match / merge but with conditions, iterations etc 'built into' it.
    I can read up on available functions - it's just what would be the best options? and what would be the best approach to do so?
    In my function i use %rowtype - but cannot use it in owb - so what would be the alternative? i don't really want to create a lot of variables and then have a nightmare of maintaing it. are there any tips regarding this?
    having looked through Oracle dedupe - it's not really what i need because it is just DISTINCT.
    I would appreciate any help / advise on this.
    Thank you very much

    thanks a lot for your reply - i will look into this option :-)
    it is a bit more complicated now as i have to re-create the match / merge and then somehow 'tweak' it to achieve the result i need.
    At the moment i am looking to breakdown the package into smaller chunks 'functions' and try creating the map that way.
    Anyway, thank you very much for your suggestion.

  • Creating a report with multiple Y-axes on one graph

    I currently have a script that will create a report with either 1, 2, or 3 graphs and has the ability to have four graphs per plot.  I would like to add functionality to this script by making the Y-axis on the graphs have multiple Y-axes.  How can I programmatically create a graph with multiple Y-axes?

    To create an new axis system use the command GraphObjNew, eg:
    Call GraphObjNew("2D-Axis","2DAxis1")
    Call GraphObjOpen("2DAxis1")        
      D2AxisBackColor = "blue"  
    Call GraphObjClose("2DAxis1") 
    Call PicUpdate
    If you have DIAdem Version 10 you can also create a new y-axis using GraphObjYAxisNew. This command is not available in versions 9.1:
    Call GraphObjOpen("2DAxis1")
    AxisNo = GraphObjYAxisNew("left")
    If AxisNo>0 Then
      Call GraphObjOpen(D2AxisYObj(AxisNo))
      D2AXISYTXT ="My new axis"
      D2AXISYTXTFONT ="Arial"
      D2AXISYTXTCOLOR ="red"
      Call GraphObjClose(D2AxisYObj(AxisNo))
    End If
    Call GraphObjClose("2DAxis1")

  • Creating SVG Chart with multiple lines

    Hi All,
    I want to create a chart with multiple lines.
    Ex: I have one emp table with empno, sal and deptno columns.
    I want to print deptno in x axis and no of employees on y axis.
    I want to print one line for employees with sal > 15000 and one more line for employee with sal =< 15000
    So one line will show no of employees with sal more than 15000 for each dept. Similar case for the other line and these 2 lines should be in different colors.
    For one line the query will go as
    select link, deptno, count(empno)
    from emp where sal > 15000 group by null, deptno
    Is this possible to draw this chart?
    Thanks,
    Manoj

    I wasn't able to do something like what you describe, but I was able to do this:
    I defined column A of the table as a Header Row, selected the cells in the table, and chose this chart type (2D 2 Axis):
    Then I clicked the chart and in the pane at the right checked 'Axis Name' in the Axis tab and added the axis names.
    Maybe this can give you an idea of how you can illustrate the relationships that you want to show.

  • I just purchased an extreme.  I have an express.  The sales guy recommended setting up a hot spot with the express and use the extreme as a base station.  What does he mean and how do I do this?  What are the advantages?

    I just purchased an extreme.  I have an express.  The sales guy recommended setting up a hot spot with the express and use the extreme as a base station.  What does he mean and how do I do this?  What are the advantages?  How do I set this up?????

    I think he means to set up the main extreme as the main router or "main base station", and then use the express to "extend" the network.
    You can look up the manual for your express here for more details:
    http://support.apple.com/manuals/
    Extend the range of your network by adding AirPort Express to your existing AirPortExtreme or AirPort Express wireless network (this is called a Wireless DistributionSystem, or WDS). "
    Extending the Range of an Existing AirPort Extreme or
    AirPort Express Network
    You can extend the range of an existing AirPort Extreme or AirPort Express wirelessnetwork by setting it up in a WDS. Wireless computers can connect to the network andshare the Internet connection, share files, and play network games. If you connect yourAirPort Express to your home stereo, computers on your wireless network can useAirTunes to play music on the stereo from iTunes. If you connect a USB printer to yourAirPort Express, all of the computers on the network can print to it.
    n Open the AirPort Setup Assistant on a Macintosh, or the AirPort Express Assistant on acomputer using Windows XP. Follow the onscreen instructions to extend the range ofyour AirPort Extreme or AirPort Express network.
    Note: Extending the range of a network using WDS may reduce overall networkperformance.

    Hi,
    The FM you are using is a perfect one. This FM is bit tricky to use. You need to perfectly pass the Reference number field. which links various input table parameters of this FM.

  • How to create Item Codes with multiple Item Description

    Hi,
    for one of my client, we need to create Item Codes with multiple Item Description.
    e.g.,
    Item Code - M00285
    Item Description 1 - Blue Paint
    Item Description 2 - Red Paint
    Is that possible in SAP Business One? If "Yes" kindly provide a solution. Else recommend an alternative method.
    Regards,
    Ammheya U. Naaik

    Ammheya,
    I just wanted to add that there is an Add-On that handles "Style, Color, Size" situations like yours.
    It allows you to define a "master" item, (Paint, for example) and then setup the various styles, colors and sizes it comes in. 
    This creates sub-items for each with the master in the ItemCode (Paint-Blue, Paint-Red, etc)
    It's called MatrixOne from Navigator.  You could find it on the partner portal with other Add-Ons.
    Hope thathelps,

    How does create a server with multiple Clients ?
    Thanks

    For a multithreaded server you will need a thread to listen and at least one thread per client. If the conversation is half duplex, one thread per client works very well, if it's full duplex you will find one thread to send and one to receive much easier to program.
    I posted a Simple Socket Server that uses 1+2*clients threads.
