GRE Wireless LAN
•
Eth_ SubMask: The Ethernet Station and the Wireless Point must be on the same subnet.
The IP address for the Wireless Bridge must correspond to the Subnet Mask. Subnet Mask
consists of four sets of three digits that divide a network into subnetworks.
•
Wirel_ ESSID: The ESSID (up to 32 printable ASCII characters) of the unit is a string used to
identify a WLAN. The ID prevents the unintentional merging of two co-located
WLANs.
•
ESSID Length: The length of the ESSID (number of characters).
•
AutoRateFallBack: Select Enable or Disable. When this is enabled the transmission rate is
defined by the past transmission status.
•
Wirel_ Channel: Select the channel to be used. The channels differ from country to country.
•
WEP key: The WEP key if the WEP option is enabled in order to activate WEP encryption for
transmissions between the stations and the Wireless Point
•
WEP type: The Wired Equivalent Privacy Algorithm (64 or 128 bits)..
•
Wire less Fragmentation Threshold: The size at which packets will be fragmented. Choose
a setting within a range of 256 to 2346 bytes. This is the option for the Fragmentation
Threshold activation.
•
Wireless 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.
•
WEP Keys #1 -#4: The default key that will be used. May be edited only if WEP type is 64
bits.
•
Preamble Type: Select Short or Long Preamble Type. Preamble is the first subfield of PDU,
which is the appropriate frame format for transmission to PHY (Physical layer). There are two
options, Short Preamble and Long Preamble. The Short Preamble option improves
throughput performance.
•
Authentication Type: Select Open System or Shared Key Authentication Type.
a. Open System: With this setting any station in the WLAN can associate with an Wireless
Bridge and receive and transmit data (null authentication).
b. Shared Key: With this setting only stations using a shared key encryption identified by
the Wireless Bridge are allowed to associate with it.
c. Both: With this setting stations communicate with or without data encryption.
•
Access Point Name: Type the Wireless Bridge's name.
•
Operational Rate Set: By default the unit adaptively selects the highest possible rate for
transmission. In case of obstacles or interference, the system will step down. Select the basic
rates to be used among the following options: 1 -2 (Mpbs), 1 -2 -5.5 – 11 (Mbps). Select the
Operational Rate set among the following options, 82 84 8B 96 (1 – 2 -5.5 -11 Mbps) or 82 84
0B 16 (1 -2 Mbps).
•
Beacon Period: Set the Beacon Period parameter, which specifies the duration between
beacon packets (milliseconds). The range for the beacon period is between the range 20-
1000 with a typical value of 100.
