802.11D Operation - Fluke AIRCHECK User Manual

802.11d Operation

If an access point uses the 802.11d standard, it transmits an
ISO country code in its beacons and probe responses. When
the tester receives this code, it transmits only on channels
that are legal in the country, and uses only power levels
that are legal.
If the tester does not receive a country code, the tester
operates in "world mode":
• The tester uses only channels and power levels that are
legal in all countries. The channels are 1 to 11 in the
2.4 GHz band.
•
The tester will not transmit probes on channels 12, 13,
and 14 in the 2.4 GHz band.
• The tester will not transmit in the 5 GHz band unless it
sees access points that operate in that band.
• The tester uses the lowest transmission power that is
legal in all countries.
The bars at the bottom of the display and icons on the
networks and access point displays show the status of the
country code:
Green bars: The tester received a country code from
one or more access points. All country codes received are
the same, and they all agree with the setting in Tools > Set
country. The tester operates on channels and uses power
levels that are legal in that country.
White bars: The tester has not received a country code.
The tester operates in world mode.
Red bars: The tester received a country code that is
different from the setting in Tools > Set country. To identify
the network or access point that transmits the code, select
Networks or Access Points, then look for the red bars in the
802.11 column.
The Access Point Details screen shows the 802.11d country
code that the access point transmits. Appendix C shows the
countries for the codes.
