Chapter 7: Operation Spectrum management
X axis and Y axis
The X-axis shows a stylized view of the selectable wireless channels. Adjacent channels on the
display have a 10 MHz overlap. Channels are displayed separately for clarity. The axis is labeled
using the channel center frequencies in MHz.
The Y-axis shows the interference power levels from –100 to –40 dBm.
Channel states
The active channel (channel 5 in Figure 117 ) is always marked using hatched green and white
lines. The width of the hatching is directly proportional the channel bandwidth spectral occupancy
of the channel.
The individual channel metrics are displayed using a colored bar and an “I” bar. The colored bar
represents the channel state (
Table 105 ).

Color State Meaning
Green Active The channel is currently in use, hosting the Point-to-Point
wireless link.
Orange Interference The channel has interference above the interference
threshold.
Blue Available The channel has an interference level below the
interference threshold and is considered by the Spectrum
Management algorithm suitable for hosting the
Point-to-Point link.
Grey Barred The system administrator has barred this channel from use.
For improved visibility, an additional red “lock” symbol is
used to indicate that a channel is barred.
