KPWL-0300 User's Manual 

45 

9.2  DFS 

This section explains how setting W52 (Ch 36 to Ch 48) or W56 (Ch 100 to Ch 140) as the relay circuit channel 
affects behavior. 
 
The frequency band prescribed by W56 overlaps the frequency band already used by various types of radar (such 
as meteorological radar, etc.) Because of this, a dynamic frequency selection (DFS) function is required to change 
the frequency to make sure wireless LAN communication is not affected by meteorological radar, etc. 

 

This also means that the W56 setting will result in behavior that is different from the W52 setting. When a radar 
wave is detected, the DFS function changes to a different channel, which generates the operation described below. 

 

Channel scan is performed to determine the new channel. During the channel scan, the POWER LED flashes 
and internet access from wireless terminals is disabled. This condition may continue for one minute or longer. 

 

Since the channel change is automatic, operation may be on a channel that is different from the channel setting.
