Advanced - Planet Networking & Communication WL-3560 User Manual

u
Preamble: There is two options can be selected: Short & Long Preamble, Long
Preamble. 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 802.11), and an optional Short Preamble and header
(as described in IEEE 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.
u
Support Band: The supported bands of WL-3560 are 11B, 11G, and 11G Turbo (11A and
11A Turbo are preserved for future usage). With all options selected, WL-3560 can keep
the highest flexibility when making connection to AP. If you fix the WLAN band for both
AP and WL-3560, it can skip the initial negotiation time.

3.3 Advanced

Additional security can be achieved by using any of the following encryption methods: WEP
(Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA-PSK (Pre Shared Key).
When "Enable" is selected in "Encryption" field, WEP encryption is activated. Please enter
the appropriate parameters to these fields.
u
Auth. Mode:
Ø
Auto:
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.
