Advance Options
The Advance configuration provides advance function about network environment if you want
to know more detail of the Advanced configuration. Please consults administrator.
The WLAN Utility also offers the advanced configuration for user to set the 802.11g Wireless
LAN PCI Card under certain network environment. These advanced options include Power
Management, RTS and Fragmentation Threshold. To enable the advanced configuration, go to
the Configuration tab and click the Advance button.
Power Management
The Power Save option is designed to conserve battery life of you computer. When Power Save
is enabled, your 802.11g Wireless LAN PCI Card will go into sleep mode to minimize power
consumption.
Warning: When power saving mode is enabled, the Access Points you use need
to support power saving as well so that the communication can be established.

RTS Threshold
RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. “Hidden
Node” is a situation in which two stations are within range of the same Access Point, but are not
within range of each other. The following figure illustrates an example of the “Hidden Node”
problem. Both stations (STA) are within range of the Access Point, however, they cannot hear
each other. Therefore, they are hidden nodes for each other. When a station starts data
transmission with the Access Point, it might not notice that the other station is already using the
wireless medium. When these two stations send data at the same time, they might collide when
arriving simultaneously at the Access Point. The collision will most certainly result in a loss of
messages for both stations.
