Scanning Available RF Spectrum

The MXW Wireless components operate in unlicensed
spectrum that is shared with other wireless devices
operating in the same area, such as cordless phones,
walkie-talkies and intercoms. The MXW control software
features a scanning tool that surveys the RF spectrum
for these devices. It calculates the percentage of Radio
Frequency Interference (RFI) in the area and provides
recommended channel count ranges. It provides the current
and peak percentages of RFI activity for up to 24 hours.
During a scan, any microphones Linked to that Access
Point are turned off in order to survey the area for
interference from other devices. The scan calculates the
current spectrum and the minimum spectrum available,
which provides the greatest level of safety in determining
channel count availability in a space. The Minimum
Spectrum Available data will persist until a new scan is
performed or the data is cleared.

Radio Frequency Interference (RFI)
The scanner analyzes the spectrum and divides the data
into three categories:
No/Low (Green): Clean RF available for MXW system.
Moderate (Yellow): Some moderate interference is
detected, still usable by the MXW system.
High (Red): Busy RF occupied by other devices.
Estimated Mic Channel Count
The scanner provides two estimate levels for MXW
microphones:
Conservative (More Robust)
Reference this channel estimate for maximum channel
stability. It includes extra usable spectrum for optimal
interference avoidance, allowing multiple microphones to
find available frequencies simultaneously.
Aggressive (More Channels).
Reference this channel estimate if a higher channel count is
necessary for the installation. It reserves only the minimum
required extra spectrum for interference avoidance. Be sure
to occasionally monitor the spectrum and make channel
adjustments if the RFI increases.
