Using different Wlans for Office & Warehouse environments

Hi everybody,
I'm working on a Wi-Fi project, and i would like to have your opinion on a design question.
I have two categories of buildings to cover : warehouses and offices
In warehouses i will have RF Scanners that communicate with a logistics application (local servers in the warehouses)
In office buildings, standard laptops that will be used in offices and meeting rooms and communicate with file servers, email servers, proxys for browsing etc...
I was wondering about the need to create 2 different wlans/SSIDs for the 2 environments. In the previous Wi-Fi architectures that i have seen there were often different SSIDs for Warehouses & Offices, but i can't really see the advantage of doing this.
The RF Scanners are quite recent and support the same security standards that we will use for laprops (i.e. WPA2 Enterprise with EAP-TLS authentication and AES encryption)
As there are many local servers in the buildings, the wlans will be H-REAP (or now "FlexConnect") local-switched, so devices will be put in different local vlans depending on their location.
I guess 2 wlans is always more complicated to manage than 1 unique wlan, so as of today I don't really see any advantage of creating 2 wlans.
What do you think about it ?
Thanks in advance for your help

I hope you will be running WLC that can support 7.2.110.0 because there's an option called RF profiles.  You may want to consider, for example, the WAPs in the warehouse to run particular RF profiles while your office run different RF profiles.

Sorry, but I would be apprehensive to believe what the marketing people say until you've personally tested the roaming of these scanners.  There are still some very expensive scanners which will only talk in 1 Mbps in 802.11 b, PSK, and SSID should NOT be broadcasting.

  • APs using different channels for the same SSID

    Hi,
    This might be a stupid question, but I am wondering why my Aironet 1602i and 2602i access points connected to the same controller would use different channels for the same network. Would this be to avoid interference? If so, I am planning to put 9 access points throughout the office and they will be fairly close to each other. Would this increase the risk of interference?
    Thanks,
    Tibet

    That is normal. The WLC is determining the best channel and being in different channels is the best. When you add more, the WLC will decide by the use if RRM what channels and power levels to allocate to each AP.

  • Using different templates for the desktop and phone versions of the same blog

    I have a site which was created in Adobe Muse and is hosted on Business Catalyst.
    I have created both a desktop and a phone versions of the site.
    I  want to know how I can integrate the blogs that I  currently have on the desktop site with the phone version that I just did, using different templates for the desktop and phone versions of the same blog. This is in order to ensure that visitors to the blogs on the website are directed to the templates that render correctly for the devices they are using.
    My current approach has been to create both a desktop and phone versions of the blogs. The problem with this however, is that the dates are different and the comments are separated between the two blog versions!
    I  have also tried enabling mobile templates in BC, but still couldn't find a way to specify the mobile versions of the templates for the same blog?
    To recap my problem, I basically  need a solution where the same blog uses different templates for desktop and mobile (both templates use different navigation headings and menu styles)
    Thanks.

    There can be few reason for this, including page contents links or contents used in phone/tablet version.
    Please provide the site url , also try to publish the site as a trial site in Business Catalyst with all layouts which would help to isolate the issue.
    Thanks,

  • WLAN for a Warehouse

    Hi,
    We are taking over a new warehouse in the next few months. The business has a requirement for total Wireless Coverage on the Warehouse shop floor for use by stock pickers (with mobile devices). The key challenge I see here is the fact that the racking will block/reflect the RF signal. This can be addressed by using many many APs with directional antennae. I was wondering if anyone out there has any other tips for deploying a WLAN in a warehouse environment.
    Cheers
    Marcus

    Hi Marcus,
    Jeff's got a good point.
    If I may be allowed to make some additions, how do you plan to power your AP's? Will you be using a Wireless LAN Controller?
    AP's (1240 for instance) require 15.4 watts of power. You can get a PoE switch, power brick/injector or a mid-span switch. The 1250, in Autonomous mode, requires 18.4 watts of power. If you are using a Wireless LAN Controller, the 1250 can operate at 15.4 watts of power.
    1240/1250 series are "ruggedized" version AP's. They have full metal enclosures and have multiple antennaes. During the pre-purchase stage, you have the option to choose a wide assortment of antenna to employ from Rubber Duckies to the rods and (the extreme) the dish.
    I am not sure if this has been brought up to you but with a Wireless LAN, you can also gain the optional benefit of two other functions:
    1. Wireless VoIP;
    2. Asset Location and/or Asset Tracking
    Hope this helps.

    Hi,
    We have a requirement to invoke different change attribute request workflows (change password ,change email etc..) from external JSPs..
    I want to apply different stylesheets for each workflow. In the workflow URL if i enter style=stylesheet-name its not using that stylesheet. Always its using the same base stylesheet (wf_changeattr.xsl). How can i use different stylesheets? Any pointers on this is appreciated.
    Thanks inadvance..

    Thanks for your response. Now i am able to invoke different xsls for different workflows.
    I did a mistake by entering style=stylesheet-name. I verified the same with xsl=stylesheet-name.
    Its working fine now..

  • How to Use different icons for JTree in the same level

    Hi guys, i come cross a problem with JTree. The module need a JTree which need to represent items in the same level using different icons. For example:
    [Icon for Root]Root
    |
    |_____________[Icon for Table] TABLES
    |
    |_____________[Icon for Index] INDEXS
    |
    |_____________[Icon for Views] VIEWS
    As i know, the default behavior for JTree is using the same icon for all leaves and
    the same icon for all node that has children. How can i achieve that?
    Thansk a lot!

    subclass DefaultTreeCellRenderer. if you overwrite the method below, then you can set the icon to whatever you want....!
        public Component getTreeCellRendererComponent(JTree tree, Object value,
                                    boolean sel,
                                    boolean expanded,
                                    boolean leaf, int row,
                                    boolean hasFocus) {
         String         stringValue = tree.convertValueToText(value, sel,
                               expanded, leaf, row, hasFocus);
            this.tree = tree;
         this.hasFocus = hasFocus;
         setText(stringValue);
         if(sel)
             setForeground(getTextSelectionColor());
         else
             setForeground(getTextNonSelectionColor());
         // There needs to be a way to specify disabled icons.
         if (!tree.isEnabled()) {
             setEnabled(false);
             if (leaf) {
              setDisabledIcon(getLeafIcon());
             } else if (expanded) {
              setDisabledIcon(getOpenIcon());
             } else {
              setDisabledIcon(getClosedIcon());
         else {
             setEnabled(true);
             if (leaf) {
              setIcon(getLeafIcon());
             } else if (expanded) {
              setIcon(getOpenIcon());
             } else {

  • How to use different iViews for variables and queries?

    Hi all!
    I need to use separtate iViews for storing variables and extracting queries.
    For example, I have one variable "Currency" for two different queries,  and I need that all of these queries (in separate iViews) would use the value of currency was put by user in the first iView with only one input.
    How can I do this task? Is it possible at all?
    Thanks for replies.

    Hello Alex,
    You have to use EP client framework (EPCF) in your development.
    I hope this idea will help you.

  • Multiple RAC databases on same GI using different subnets for Public i/face

    Hello. We are configuring a 2 node cluster. That cluster will host several RAC databases. For security reasons our networking team want to create separate subnets for the application traffic to each specific RAC database on the cluster.
    E.g. application 1 has 2 application servers that will connect to RAC database PROD1 via one subnet, application 2 has 3 application servers that will connect to RAC database PROD2 via a different subnet, etc.
    In addition the networking team want to configure a separate management subnet that DBAs etc. will use to administer all RAC databases and infrastructure in the cluster.
    Grid Infrastructure version 11.2.0.2. Database versions will vary from 10.2.0.x to 11.2.0.2. All databases will utilise RAC.
    We want to take advantage of SCAN listener functionality to support connectivity to all databases on the cluster. Forum thread 2199620 [https://cn.forums.oracle.com/forums/thread.jspa?threadID=2199620] suggests that 11gR2 supports multiple subnets, which looks to be exactly the feature we need. Please can you confirm how this works and point us to any documentation (standard docs, white papers, MOS, etc.) that might help us configure this.
    Document referenced in thread 2199620 was not exactly what we were looking for, and didn't translate too well in Google Translate.
    Any guidance much appreciated. Thanks, Rich.

    Thanks Levi. Your advice is very much appreciated.
    Your statement that we can only have one SCAN listener listening on one public network is actually the clarification I was looking for.
    For anyone else reading this thread I believe this gives us 3 options:
    1) Configure a SCAN listener and have all applications, and all management/administration, connecting to the corresponding database on the same cluster via that SCAN listener, all on the same subnet.
    2) Configure a SCAN listener for use by all applications connecting to the corresponding database on the same cluster, and use TNSNAMES/VIP for management/administration traffic, both on separate subnets (by configuring the LISTENER_NETWORKS parameter)
    3) Configure a SCAN listener for use by applications connecting to one of the databases on the cluster via one subnet, use TNSNAMES/VIP for all other applications connecting to other databases, each using their own subnet. Plus, the management/administration could be via another subnet utilising TNSNAMES/VIP.
    From our perspective we will work out the best one for us and implement accordingly.
    Thanks again for your timely and comprehensive response.

  • Use different Layouts for Summary and Details in Drill down report

    Hi All,
    I have a 2 level drill down report in ALV.
    The summary report has certain fields and the Detail report has different fields. Now my problem is that when i use a default layout (with all fields of summary report) for the summary report, and drill down to the detail report i'm missing the fields on detail that are not in Summary. And if i save the default layout as default (with all fields of Detail) and go back to sumary, I'm missing the some other fields on summary (which are not on detail report).
    Is there a way to make different default layouts for each of those summary and detail reports:
    Also as the layouts are choosen by the user, i cannot hardcode any particular layout;
    So if the user chooses a layout for detail; it has to stay the same layout for the detail report if he goes to summary and then back to detail; unless the user changes the layout again.
    I'm using two different Layout types for each report. but i still cannot get the desired effect.
    Data:
          gt_layout_s             type slis_layout_alv,
          gt_layout_d             type slis_layout_alv,
      call function 'REUSE_ALV_GRID_DISPLAY'
        exporting
          i_callback_program       = g_repid
          is_layout                = <b>gt_layout_s</b>
          i_callback_top_of_page   = g_top_of_page
          i_callback_user_command  = g_user_command
          i_callback_pf_status_set = g_status
          i_save                   = g_save
          is_variant               = gs_variant
          it_fieldcat              = gt_fieldcat[]
          it_events                = gt_events[]
        importing
          es_exit_caused_by_user   = gs_exit_caused_by_user
        tables
          t_outtab                 = it_summary.
      call function 'REUSE_ALV_GRID_DISPLAY'
        exporting
          i_callback_program       = g_repid
          is_layout                = <b>gt_layout_d</b>
          i_callback_top_of_page   = g_top_of_page
          i_callback_user_command  = g_user_command
          i_callback_pf_status_set = g_status
          i_save                   = g_save
          is_variant               = gs_variant
          it_fieldcat              = gt_fieldcat[]
          it_events                = gt_events[]
        importing
          es_exit_caused_by_user   = gs_exit_caused_by_user
        tables
          t_outtab                 = it_detail_disp.

    Here is how you differentiate between the layout of two different grids. There is the parameter, IS_VARIANT in the function. You usually leave it empty or pass only the report name and username. <b>What you need to do is to pass unique string for each grids to the HANDLE field of the parameter IS_VARIANT.</b> You can probably hard code it as HEADER and DETAILS in your case. Once that is done, system identified that these two different layout for different grids.

    Ravi
