Chapter 16
FCC/IC DFS Installation
Procedure
FCC/IC 5.4/5.3 GHz Links: Background
The FCC/IC regulation for 5.4/5.3 GHz allows unlicensed wireless data equipment, provided
that it does not interrupt radar services. If radar activity is detected, the equipment must
automatically change frequency channel. This feature is termed Dynamic Frequency Selection
(DFS). According to the standard, a channel with active radar is prohibited from use for 30
minutes. Before using a channel for transmission, the radio equipment must probe it for radar
signals for a period of 60 seconds.
Ceragon radio products support DFS as well as ACS.
An immediate consequence of the FCC/IC regulation for 5.4/5.3 GHz is that the standard
method of link installation using a single default fixed installation channel, cannot be used.
Instead of the installation procedure of Chapter 5, a link activation method is used.
The ODUs are either supplied from the factory ready for use at 5.4 GHz or 5.3 GHz FCC/IC or
alternatively, they can be set up for these bands using the FibeAir2000 Manager.
FCC/IC 5.4/5.3 GHz Link Activation
To Activate a FCC/IC 5.4/5.3 GHz Link:
1. Install FibeAir2000 Manager software as usual.
2. Connect the PC to the IDU-ODU pair to be used as the local site.
3. Run the FibeAir2000 Manager and log in as Installer. You will see the following win-
dow:
Note
The following procedure is generic to all relevant Ceragon radio products.
What you see on your running FibeAir2000 Manager may differ in some
details from the screen captures used to illustrate this chapter.
