LABEL DESCRIPTION
Hide ESSID Select this check box to hide the ESSID in the outgoing beacon frame so a station
cannot obtain the ESSID through passive scanning using a site survey tool.
Tx Power
Set this field if you need to conserve power consumption (especially for notebook
computers). This control changes the strength of the ZyAIR’s antenna gain or
transmission power. Antenna gain, measured in dBm (decibel relative units compared to
milliwatts), is the increase in coverage. Higher antenna gain improves the range of the
signal for better communications.
Select Level 0 (Maximum Power) to set the ZyAIR’s antenna to transmit at 17-dBm.
Select Level 1 to set the ZyAIR’s antenna to transmit at 15-dBm.
Select Level 2 to set the ZyAIR’s antenna to transmit at 13-dBm.
Select Level 3 (Minimum Power) to set the ZyAIR’s antenna to transmit at 11-dBm.
This allows for the least power consumption.

Fragmentation
Threshold
The threshold (number of bytes) for the fragmentation boundary for directed messages.
It is the maximum data fragment size that can be sent. Refer to Section 2.3 for more
information.
It is the maximum data fragment size that can be sent. Refer to Section 2.3 for more
information.
RTS/CTS
Threshold
Data with its frame size larger than this value will perform the RTS/CTS handshake.
Setting this attribute to be larger than the maximum MSDU (MAC service data unit) size
turns off the RTS/CTS handshake. Refer to Section 2.4 for more information.
Setting this attribute to zero turns on the RTS/CTS handshake.
Setting this attribute to be larger than the maximum MSDU (MAC service data unit) size
turns off the RTS/CTS handshake. Refer to Section 2.4 for more information.
Setting this attribute to zero turns on the RTS/CTS handshake.
Preamble
