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 activ-
ity is detected, the equipment must automatically change frequency chan-
nel. 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.
RADWIN 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 installa-
tion 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 RADWIN Manager.
FCC/IC 5.4/5.3 GHz Link Activation
¾
To Activate a FCC/IC 5.4/5.3 GHz Link:
1. Install RADWIN Manager software as usual.
2. Connect the PC to the IDU-ODU pair to be used as the local site.
Note
The following procedure is generic to all relevant RADWIN radio products.
What you see on your running RADWIN Manager may differ in some details
from the screen captures used to illustrate this Appendix.
