Power Saving
Power Saving mode allows to using reduced power during idle time by going into “sleep” mode, saving
energy costs.
•
Disable –The card will always set in active mode.
•
Enable(Fast) –Enable the card in the power saving mode when it is idle, but some components of the
card is still alive. In this mode, the power consumption is larger than “Max“ mode.
•
Enable(Max) –Enable the card in the power saving mode when it is idle.
Preamble Type
defines the length of CRC block in the frames during the wireless communication.
•
Long –“Long ” can provide more reliable communication.
•
Short –“Short ” is suitable for high traffic wireless network.
•
Auto –the card will auto switch the preamble mode depending on the wireless networks card is
connecting to.
Fragment Threshold
The value defines the maximum size of packets, any packet size larger than the value will be fragmented.
If user have decreased this value and experience high packet error rates, user can increase it again, but it
will likely decrease overall network performance. Select a setting within a range of 256 to 2346 bytes.
Minor change is recommended.
RTS Threshold
Minimum packet size required for an RTS (Request To Send). For packets smaller than this threshold,
an RTS is not sent and the packet is transmitted directly to the WLAN. Select a setting within a range of
0 to 2347 bytes. Minor change is recommended
Receive Antenna
Define the receive antenna. If “Diversity” is selected, the card will auto switch to the antenna with high
signal strength to receive data.
