GRE Wireless LAN
•
Fragmentation threshold: The size at which packets will be fragmented. Choose a
setting within a range of 256 to 2346 bytes.
•
RTS Threshold: Minimum packet size to require an RTS (Request To Send). For
packets smaller than this threshold, an RTS is not sent and the packet is transmitted
directly to the WLAN. This is the option for the RTS Threshold activation.
•
Authentication Type: Select Open System, Shared Key, or Both Open System: With
this setting any station in the WLAN can associate with an Wireless Bridge and
receive and transmit data (null authentication). Shared Key : With this setting only
stations using a shared key encryption identified by the Wireless Bridge are allowed
to associate with it. Both: With this setting stations communicate with the Wireless
Bridge either with or without data encryption.
•
Preamble Type (Short/ Long): Preamble is the first subfield of PPDU, which is the
appropriate frame format for transmission to PHY (Physical layer). There are two
options, Short Preamble and Long Preamble.
•
Rate: By default the unit adaptively selects the highest possible rate for transmission.
Select the basic rates to be used among the following options 1 -2 -5.5 -11 (Mbps).
•
Auto Rate Fall Back: When this is enabled the transmission rate is the optimum
rate. In case of obstacles or interference, the system will automatically fall back.
•
Regulatory Domain: The value of this field is already set and can not be modified.
If you press the "Advanced" button on the following three operational modes are available.
For each mode you can either view or modify the Wireless LAN parameters of the Wireless
Operational Settings window.
•
Access Point: This mode provides access from wireless stations to wired LANs and
from wired LANs to wireless stations. Furthermore, wireless stations within the range
of the AP device may communicate with each other via the AP.
•
Access Point Client: This mode allows the connection of one or more remote LANs
with a central LAN, creating thus an extended single virtual LAN. In this way, any
