Preamble: Select Long or Short/Long (auto) 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 interoperates 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.
Support Band: There are three bands available for selection; 11B (11Mbps), 11G (54Mbps) and
11G Turbo (108Mbps).
Advanced
The Advanced settings help you to control the 108Mbps Wireless USB Adapter to adjust with
wireless devices in certain environment.
Auth. Mode: Five options are available: Disable, Auto, Shared Key, WPA/WPA2, and WPA-
PSK/WPA2-PSK. Select Auto, Disable for other authentication feature. If one of the two options is
selected, it is required to select the Encryption mode from the next dropping list.
