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.
