Glossary

Access control
Allows for the assignment of PINs, which protect against unauthorized access to networked components from a computer running Wireless Workbench or other Shure control software.

Backup frequency
A frequency that is compatible with the RF environment and isn't assigned to a device. A backup frequency can be deployed in the event of interference. Frequency statuses:

• In use: A frequency that has been allocated to a device.
• Ready: A backup frequency that is ready to be used.
• Degraded: A backup frequency that is not suitable for use and is unavailable to be deployed. Compatible frequency

A frequency that does not conflict with other frequencies being used in your environment.

Compatibility level
Adjusting the compatibility level allows you to dictate the spacing between synthesized frequencies and other frequencies, including intermodulation products. Sometimes called compatibility settings or compatibility profiles. There are 3 compatibility levels:

• Standard: Uses the default channel spacing. Use this setting to achieve a balance between robust operation and number of frequencies.
• Robust: Uses large spacing between frequencies to avoid interference. Because this setting requires the greatest spacing between frequencies, fewer frequencies will be available in a given amount of spectrum compared to the Standard or More frequencies settings. If enough frequencies can be found, this is the best option.
• More frequencies: Uses narrower spacing to assign more frequencies. Use this setting when the greatest possible number of frequencies is needed. Because this setting allows the closest spacing of frequencies, the working ranges of the systems using them may be more limited, including transmitter to receiver antenna distance and minimum transmitter to transmitter distance.

Equipment profile
A group of coordination settings that apply to all devices of a certain make and model. Equipment profiles can be edited in Wireless Workbench. Sometimes called a device profile.

Exclusions
As part of frequency coordination, you can define single frequencies and ranges to avoid in the frequency calculation. These are called exclusions.

Frequency list
A list of available primary and backup frequencies calculated in Wireless Workbench or a Spectrum Manager. Sometimes called a compatible frequency list, or CFL.

Frequency pool
The frequency list is organized into pools, which are groups of frequencies that are compatible with certain devices. Frequencies in a pool share a common device series (ULX-D, QLX-D, etc.), band, and sometimes RF profile, inclusion group, or zone. Because of these commonalities, the frequency server can deploy any frequency from a device's pool to that device.

Frequency server
AD600 and AXT600 act as frequency servers to deploy compatible frequencies to devices and respond to device requests for new frequencies (for example, in the event of interference).

Intermodulation products
Small RF spikes that are a by-product of modulation and can potentially cause interference. Also called intermods, these are extra frequencies that take up space in your spectrum.

Managed device
A managed device is a device served by the Spectrum Manager. Monitor the device list in the Wireless Workbench properties panel to make sure your RF channels are operating on planned frequencies.

Monitoring threshold
The level at which a frequency is considered degraded (not suitable for use). Frequencies above this level are marked as degraded.

Re-calculate
Runs the calculation again to find different frequencies for your devices.

Re-deploy
Delivers coordination changes to your hardware.

RF zones
A tool that helps you maximize the number of available frequencies when you're coordinating RF across multiple areas in a large venue. They are commonly used in sports arenas, campuses, and corporate environments.

RF zones rely on distance between devices to allow for frequency reuse. For example, if you have systems in 2 buildings in separate parts of a campus, you can reuse frequencies as long as there is enough distance between them. Each building would be its own zone in a coordination.

AD600 is set up to manage a single zone. To coordinate multiple zones, use in conjunction with Wireless Workbench.

RSSI
Received signal strength indicator, or how much RF energy is present at a given frequency.

Scan peak threshold
The frequency at which the calculation will assume an active transmitter is present.

Shure control
Software from Shure that allows for control of devices, such as Wireless Workbench.

User groups
Predefined sets of frequencies designed to control where wireless systems can operate within a region or country.

Virtual channel
Virtual channels are created to represent offline devices that you plan to add to your network or non-networkable (and thirdparty) equipment that will never come online. A virtual channel acts as a placeholder during a coordination so that the offline device will have a frequency included for it in a coordination. Sometimes called virtual devices.
