About the wireless LAN standards (Continued)
Bandwidth and Channel
Wireless LAN unit for both the internal and external antennas are built into the AP-90M.
As the default setting, Wireless 1 (internal antenna) is set to 2.4 GHz, and Wireless 2 (external antenna) is set
to 5 GHz.
Set the desired “Frequency Band” or “Bandwidth.”
• The channels written in the table below are the channels used in the world.
However, the channels and bandwidth that can be used differ, depending on the country, or the local regulations.
When setting multiple access points with the 80 MHz bandwidth on 5 GHz, or 20/40 MHz bandwidth on 2.4 GHz, set the
channels away from each other, to prevent signal interference.

1
Wireless 1 and 2’s frequency bands cannot be used when both of them are set to 2.4 GHz or 5 GHz.
*
2
80 MHz bandwidth can only be used in Wireless 2.
(80 MHz bandwidth cannot be used, depending on the country.)
*
3
For Wireless 1, when 5 GHz is selected for “Frequency Band,” and 40 MHz is selected for “Bandwidth,” the
DFS function channels cannot be used.
