Hawking Technology HWC54D - Manual (Page 12)

Parameter Description
Network Type Infrastructure – This operation mode requires the presence of an
802.11 Access Point. All communication is done via the Access
Point or Router.
Ad-Hoc – Select this mode if you want to connect to another
wireless station in the Wireless LAN network without going
through an Access Point or Router. Peer to Peer.
Transmit Power If you wish to lower the transmit power of the card to save the
power of your system, you can select the lower percentages from
the list.
11B Preamble Type The preamble defines the length of the CRC block for
communication among wireless stations. This option is only active
in the Ad Hoc network.
There are two modes including Auto and Long Preamble. If
“Auto“ mode is selected, the card will auto switch the preamble
mode depending on the wireless stations which the card is
connecting to.
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 wireless network. Select a
setting within a range of 0 to 2312 bytes. Minor change is
recommended.
Fragment Threshold The value defines the maximum size of packets; any packet size
larger than the value will be fragmented. If you have decreased
this value and experience high packet error rates, you can
increase it again, but it will likely decrease overall network
performance. Select a setting within a range of 256 to 2312 bytes.
Minor change is recommended.
Channel This setting is only available for Ad Hoc mode. Select the number
of the radio channel used for the networking. The channel setting
should be the same with the network you are connecting to.
