802.11 Mode

Select 802.11b to allow only IEEE 802.11b compliant WLAN devices to associate with

 

the ZyXEL Device.

 

Select 802.11g to allow only IEEE 802.11g compliant WLAN devices to associate with

 

the ZyXEL Device.

 

Select 802.11b/g to allow either IEEE802.11b or IEEE802.11g compliant WLAN

 

devices to associate with the ZyXEL Device. The transmission rate of your ZyXEL

 

Device might be reduced.

 

If you push the AG switch to the A side on the rear panel, this field is read-only and

 

displays 802.11a to allow only IEEE 802.11a compliant WLAN devices to associate

 

with the ZyXEL Device.

This field is available when you push the AG switch to the A side on the rear panel.

802.11h

The IEEE 802.11h standard defines two mechanisms (DFS and TPC) for IEEE

stations

802.11a WLAN devices to avoid interference with other devices, such as satellites

 

and military radar.

 

DFS (dynamic frequency selection) allows the AP to detect other devices in the same

 

channel. If found it, the AP changes to different channel, so that the AP can avoid

 

interference with radar systems or other wireless networks.

 

TPC (transmit power control) helps reduce the wireless device’s transmission power

 

to avoid interference with satellites.

 

Select the check box to also allow the WLAN devices which do not support IEEE

 

802.11h to associate with the ZyXEL Device. Otherwise, clear the check box to allow

 

only IEEE 802.11h compliant WLAN devices to associate with the ZyXEL Device.
