LevelOne WPC-0301 - Manual (Page 21)

WARNING: Country domain can't be choosing by end-user, because the incorrect region may be in
violation of applicable laws.
Power Mode:
There are 3 modes to choose from.
• Continuous Access Mode (default) – the wireless LAN adapter is constantly operating with full
power. This mode consumes the most power.
• Maximum Power Save – the wireless LAN adapter consumes the least power. This mode only
operates when there is wireless network activity.
• Power Save – the wireless LAN adapter consumes 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 two modes the user can select, including 11B and 11G. The default setting
is 11B and 11G are enabled, which is interoperable with both 11B and 11G devices.
Note: user must select one of 11B or 11G at least; otherwise the wireless connection will not function.
