Preamble Type
The preamble type property controls the length of the preamble. The type of preamble allows
the user to trade off compatibility with pre-802.11b wireless LAN cards for some transmit
throughput increase on 802.11b wireless LANs. Set preamble type:
• Short: Only compatible with 802.11b wireless LAN networks. Allows faster
transmittal of data on 802.11b wireless LAN networks.
• Long: Compatible with 802.11b and pre-802.11b wireless LAN networks.
• Auto: Automatically choose short or long preamble type. Default setting.
Radio
Set this attribute to control your radio emissions. Some situations may require you to turn off
your Compaq 802.11b WLAN Mini PCI radio. Flying on an airplane is one example where the
radio is required to be turned off.
• On: Card can transmit and receive signals. Default setting.
• Off: Card cannot transmit and receive signals.
Rate
Sets transmit rate of the Compaq 802.11b WLAN Mini PCI card. Setting a fixed rate will force
the card to connect at only that speed to other 802.11b and pre-802.11b clients or access points.
Setting the speed to Auto allows the card to automatically select the optimum transmit rate based
on the capabilities of the other clients and access points
.
• Fixed 1 Mbps: Set transmit rate to 1 Mbps.
• Fixed 2 Mbps: Set transmit rate to 2 Mbps.
• Fixed 5.5 Mbps: Set transmit rate to 5.5 Mbps.
• Fixed 11 Mbps: Set transmit rate to 11 Mbps.
• Auto: Set transmit rate to auto adjustment. Default setting.
