Power Mode: There are 3 modes to choose.
•
Continuous Access Mode (default) – the USB Dongle is constantly
operating with full power and it consumes the most power.
•
Maximum Power Save – the USB Dongle consumes the least power and
only operates when there is wireless network activity.
•
Power Save – the USB Dongle 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 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
implementing the original version of the protocol. Click "Apply" for the changes to
