IEEE 802.11b). At the receiver, the Preamble and header are processed to aid in de-
modulation 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 com-
municate with stations implementing the original version of the protocol.

Additional security can be achieved by using the WEP (Wired Equivalent Privacy) encryption.
WEP encrypts each frame transmitted from the radio using one of the keys entered from this
panel.
u Encryption: Enable or disable WEP encryption.
u Auth. Mode:
Ø Open Authentication: With this setting, the station in the WLAN can receives and
transmits data from Access Point (null authentication).
Ø Shared Authentication: With this setting, allows communication only with other devices
with identical WEP settings.
Ø Auto Switch: With this setting, stations can communicate with the Access Point either with
or without data encryption. It will detect the AP that it connected is using which Authentication
mode and use the same mode to communicate.
u WEP Key options:
Ø Default Key: There are 4 keys available for the WEP function. Please select one of
them for WEP to operate.
Ø Network Key: You can define the WEP (Wired Equivalent Privacy) Key values by
yourself.
Ø Key Length – Please select which WEP key mode you want to use. There are
