Backhaul User Manual Draft for Regulatory Review
Configuration Page
The Configuration web page contains information and configurable parameters pertaining to the
operation of the product. The first line of information on the Configuration screen is a repeat of the
Device Type from the Status web page. The following are the parameters and their descriptions.
Timing Mode: choose whether this module will be a timing master or a timing slave. If the
operator is changing this mode, change only this parameter, save the changes and reboot. Upon
reboot different set of web based interface pages will present themselves and offer the operator
different manageable as well as configurable features.
Link Negotiation Speeds: choose the type of link speed desired for the Ethernet connection. The
default for this parameter is for all the choices to be checked.
Custom RF Frequency Scan Selection (SM) List: Choose the frequencies that the subscriber
module will scan when looking for a Backhaul – timing master. For 5.2 and 5.7 GHz modules, 20
MHz wide channels are centered every 5 MHz. The default for this parameter for 5.2 and 5.7 GHz
modules is to scan all available frequencies – all check boxes are selected by default, For 2.4 GHz
modules, 20 MHz wide channels are centered every 2.5 MHz. The default for this parameter for 2.4
GHz modules is to scan 2415 MHz, 2435 MHz, and 2457.5 Mhz – only those 3 check boxes are
selected by default.
Select 2.4 GHz scan frequencies at least 5 MHz apart. Do not simply select all
frequencies by checking every box, like you might do with the 5.2 and 5.7 GHz SMs.
Canopy gives you checkboxes in the 2.4 GHz band for channels centered every 2.5
MHz, so you have flexibility for RF engineering based on your local RF environment.
However, if you select scan frequencies only 2.5 MHz apart (in other words, if you check two boxes
in sequence), there is potential for the BHS to successfully register to an BHM that is actually
transmitting at a frequency 2.5 MHz higher as it scans up the selected frequencies. Registration
may be successful, but the link is not as good as if it had registered 2.5 MHz higher, on the actual
BHM frequency. The 5 MHz spacing for channels on 5.2 and 5.7 GHz BHSs are far enough apart
