    Title:
    Re-deploying a Solution to a Spectrum Manager
    Description:

    Overview

    A powerful feature of Wireless Workbench is the ability to perform pre-show planning and frequency coordination without having access to your networked devices. Offline, you have full access to WWB6's frequency calculator, as well as the ability to configure a majority of the settings for your Shure wireless gear.

    This topic will describe how to take a coordination performed offline, and redeploy it to an online network of gear, including an AXT600 Spectrum Manager, when you arrive on site.

    Prerequisites

    This topic's content assumes that you have already performed and saved an offline coordination using Wireless Workbench 6. Consult the Frequency Coordination tutorial video for more information on how to get to this point.

    After a coordination has been performed, the offline versions of your devices and backup frequencies will be holding the frequency values that you'll likely want to maintain and deploy to the hardware. To get to this stage, you will have had to deploy coordination results to inventory without a Spectrum Manager available (ie: on the RF Coordination Results window, you will have selected the "None" option as the managing Spectrum Manager for each zone in your coordination).

    Furthermore, the Compatible Frequency List (or CFL) that Wireless Workbench created as a result of frequency coordination can be sent to an available Spectrum Manager, which can then manage that list (dispatch frequencies to Axient receivers experiencing interference, and monitor backup frequencies for all devices). You want this. Let's walk through how to get there.

    Discover a Spectrum Manager

    You've run a frequency coordination offline, or online with gear at a previous time. You now show up to the venue, and want to push your perfect frequency list to the Spectrum Manager to take advantage of backup frequency monitoring, and automated frequency dispatching to AXT400 receivers.

    Launch Wireless Workbench and load your coordination (from a Show File). Notice that the devices in your inventory will be holding their frequency values from your calculated solution.

    Connect your computer to the same network as the Spectrum Manager you will want to utilize. Ensure the Spectrum Manager is powered on, and that it shows up in your inventory view as an online device.

    Fake a Coordination

    The next steps will walk you through "faking" a coordination in order to perform deployment: the essential step to transfer frequencies to your Spectrum Manager.

    In the Frequency Coordination tab, select "Manage Channels..." from the right sidebar.

    The Channel Summary dialog will open. This dialog shows all frequencies that will be input into the next calculation. You want to tell the calculator that all channels (both active devices and backup frequencies) should maintain their current frequency values. To do this, uncheck all rows by selecting "None" from the Select section.

    Press "Save" to close the Channel Summary dialog. On the bottom of the right sidebar of the Frequency Coordination tab, select "Calculate New Frequencies".

    The RF Coordination Results dialog will open, but with slightly different content than usual.

    In bottom of the Summary section, notice that it says "None" in the space where the number of frequencies found are usually listed. This is because we did not calculate any new frequencies (all channels were left on their current frequency values).

    Here is the critical step: In the Zone/Spectrum Manager section, we will now assign a Spectrum Manager to manage the frequencies for a given zone. Selecting a Spectrum Manager for a given zone tells Wireless Workbench to deploy the full CFL for that zone to the specified Spectrum Manager.

    For More information on zones, check out the How do I create and utilize Zones? FAQ page.

    NOTE: Only one Spectrum Manager can manage frequencies for a given zone. Also, you will only be able to assign a Spectrum Manager to manage a zone which the Spectrum Manager is currently in. To change the zone of a Spectrum Manager, change it's zone assignment from the Inventory view.

    Press "Deploy to Inventory" to send the CFL.

    The Deployment Summary dialog will open, showing the success of the deployment.

    To confirm that the CFL from your last coordination was successfully sent to the Spectrum Manager you specified, lets open the device's properties panel and view the CFL live from the device. Navigate to the Inventory view, and right-click on the Spectrum Manager, and select "Properties...".

    The Spectrum Manager properties panel shows a view of the CFL being monitored by the device (if any). The CFL view will show the in-use active device frequencies in the top portion, and the backups being monitored in the bottom section.

    Confirm that the frequency list for the specified zone is tracked in the Spectrum Manager you designated in the RF Coordination Results dialog.

    Review Concepts

    As a quick primer, let's cover the basics of how the CFL fits in with your coordinated devices and Wireless Workbench.

    When Wireless Workbench performs frequency coordination, frequencies are either calculated for or analyzed around all channels in your inventory; this includes requested backup frequencies as well.

    The solution that results from frequency coordination is the Compatible Frequency List, or CFL. The list is significant to two entities: Wireless Workbench, and the Axient Spectrum Manager.

    Both Wireless Workbench and the Spectrum Manager can host a CFL. The Spectrum Manager, however, has a few extra capabilities enabling more control and automation with regards to the CFL. Namely, these capabilities include:

    • Editing the CFL (adding, changing, removing frequencies)
    • Monitoring backup frequencies (maintaining rank of all available frequencies)
    • Automatically dispatching backup frequencies to AXT400 receivers when interference occurs

    A CFL hosted by Wireless Workbench will not exhibit any of these features. It is for this reason that you would want to re-deploy a CFL coordinated offline to a Spectrum Manager once one is on your network.
