Spectrum Management (Fixed Frequency And Wimax); Table 9: Spectrum Management Time Series Key - Motorola Canopy 300 Mbps Backhaul User Manual

Figure 57 shows an example time series plot. A time series plot displays the previous 145
measurement quantization periods. If the Canopy 150/300 Mb BH unit has not been running
for 145 quantization periods then only the number of measurement quantization periods that
are available are displayed.

Spectrum Management (Fixed Frequency and WiMAX)

The Canopy 150/300 Mb BH software allows a user to optionally fix transmit and receive
frequencies for a wireless link. Once configured, the spectrum management software will not
attempt to move the wireless link to a channel with lower co and adjacent channel
interference. Therefore this mode of operation is only recommended for deployments where
the installer has a good understanding the prevailing 5.8 GHz interference environment. (See
section 8.3.4.3 "Wireless Configuration" - Fixed Transmit Frequency, Fixed Receive
Frequency). Care must also be taken to ensure that the frequency allocations at each end of
the link are compatible. To help the user when identifying the mode of operation Spectrum
Management uses two visual cues. See Figure 58. The main page title identifies the mode of
operation using the "Fixed Frequency Mode" postfix and the selected channels are identified
by a red capital 'F'.
