802.11b, 802.11g and 802.11b/g Mixed mode
There are 11 (13 for ETSI) channel numbers that
may be assigned. Because the 802.11b signal
bandwidth is 22MHz, there are 3 non-overlapping
channels for 802.11b at 2.4GHz ISM band. To
reduce the interference problem, you may be able to
establish up to 3 wireless networks at the same area.
If you need establish 3 wireless networks, you may
assign channel number 1 to the first wireless network.
Then the channel 6 will be better for second wireless
networks and channel 11 will be the third one.
y
802.11g Super
The 802.11g Super mode occupies larger frequency
bandwidth. To avoid interfere another wireless
network operation, it is fixed at channel 6.
y
802.11a and 802.11a Turbo
The frequency band of IEEE 802.11a will vary
according to individual country regulations. The FCC (U.S) has allocated three bands,
UNII1(5.15~5.25GHz), UNII2(5.25 ~ 5.35GHz) and UNII3(5.725~5.825GHz). Each band has 4
non-overlapping channels. For Pan-Europe, there are the 5.15GHz~5.35GHz, 5.425GHz ~ 5.725GHz.
At Taiwan, the 802.11a device use the 5.725GHz ~ 5.875GHz frequency band. Refer to Appendix A to
get more information.
6.1.5 TX Power Mode
The Tx Power Mode let you can set the radio
power as you wanted. It defaults to Auto,
giving the larger range of radio transmission
available under normal conditions. As an
option, the AP’s cover range can be limited
by setting the TX Power Mode to Fixed and
choosing from 1~5 for fixed power level (1
being the shortest distance.) Finally, if you
want to prevent any radio frequency
transmission, set Tx Pwr Mode to off.
