II. Configuration
This is the page where changes the basic settings of the PC card with the minimum
amount of effort to implement a secure wireless network environment.
SSID: Service Set Identifier, which is a unique name shared among all clients and
nodes in a wireless network. The SSID must be identical for each clients and nodes
in the wireless network.
Wireless Mode: There are two types available for selection
●Infrastructure – to establish wireless communication with LAN and other wireless
clients through the use the Access Points.
●Ad-Hoc – to establish point-to-point wireless communication directly with other
wireless client devices such as wireless network PCI Card.
AdHoc Band: There are two bands available for selection- 11B and 11G
Channel: The value of channel that AP will operate in. User can select the channel
range of 1 to 11 for North America (FCC) domain and 1 to 13 for European (ETSI)
domain.
Tx Rate: Select the data rate for data transmission.
Power Mode: There are 3 modes to choose.
●Continuous Access Mode (default) – the PC card is constantly operating with full
power and it consumes the most power.
●Maximum Power Save – the PC card consumes the least power and only operates
when there is wireless network activity.
●Power Save – the PC card consumes the moderate level of power.

Preamble: Select Long or Short Preamble type. Preamble is a sequence of bits
transmitted at 1Mbps that allows the PHY circuitry to reach steady-state
demodulation and synchronization of bit clock and frame start. Two different
preambles and headers are defined: the mandatory supported Long Preamble and
header, which interoperate with the 1 Mbit/s and 2 Mbit/s DSSS specification (as
described in IEEE Std 802.11), and an optional Short Preamble and header (as
described in IEEE Std 802.11b). At the receiver, the Preamble and header are
processed to aid in demodulation and delivery of the PSDU. The Short Preamble
and header may be used to minimize overhead and, thus, maximize the network
data throughput. However, the Short Preamble is supported only from the IEEE
802.11b (High- Rate) standard and not from the original IEEE 802.11. That means
that stations using Short-Preamble cannot communicate with stations implementing
the original version of the protocol. Click "Apply" for the changes to take effect.
Support Band: There are three functions for users select, including 11B, 11G and
eXtended Range. The default setting is 11B, 11G and eXtended Range enable,
which is interoperable with both 11B and 11G devices, and provide more than
500m connection ability.
Note: user must select one of 11B or 11G at least, otherwise the wireless
connection will not function.
III. Advanced
This is the page to configure Security settings of 108Mbps wireless LAN PC card.
Encryption: 4 options are available: Disable, Enable, WPA/WPA2 and WPA-
PSK/WPA2-PSK. Select Shared Key or Auto for WEP data encryption feature.
