| Certifications | Note: Due to new FCC WiFi June 2016
regulation (FCC rules for part 15.409), the
WLAN radio used in the ISR's (specifically
C819 –A WiFi Domain with AP802
dual 802.11 radio) Cisco will be issuing a
new grant for the 5GHz dual 802.11n radio.
The specific reason for the change is due
to the inability of the radio to detect the various
radar pulses (DFS function) over the entire
bandwidth of the channels in the 5250-5350
and the 5500-5700 A radio channel bands
(which will be disabled). As a consequence
the radio will now operate from 5150-5250
and 5745-5850 A radio bands. This will
provide a total of nine channels in the 5GHz
range. |
