RTS Threshold

0 – 4.096 Bytes

Unicast and management
frames exceeding the
threshold value specified
here are transmitted by
means of an RTS/CTS
handshake procedure.

Fragmentation
Threshold

0 – 4.096 Bytes

Unicast frames exceeding
the threshold value specified
here are fragmented.

Maximum Rate

1; 2; 5,5; 6; 9; 11; 12; 18;
22; 24; 36; 48; 54 Mbps

The maximum rate of
transmission between the
WLAN AP and the WLAN
client.

802.11 b/g Mode

Mixed, b-only, g-only

802.11 connection mode.

Hidden SSID

Yes / No

Suppresses transmission of
the SSID.

Interference
Avoidance

Yes / No

A procedure to avoid
interference.

Security Settings

Encryption settings (see
below)

MAC Access Filter

1 – 64

Authorized clients (white list)

BSS Isolation

Yes / No

Prevents the WLAN clients
from detecting one another.

Cipher Length

64 / 128 / 256 Bits

The length of the key used in
the security modes.

Distribution Interval Seconds

The interval between
exchanges of the key.

Radius Settings

IP Address, Port, Secret

Radius server settings.

Multiple SSID
Settings

SSID Name, VLAN and
Security Settings

1 to 3 additional SSIDs

You configure an open system, i.e. a system in which all authentication and
encryption procedures are deactivated, by selecting the item ‘Open System’.

The ‘BSS Isolation’ parameter prevents WLAN clients from contacting each
other via one and the same AP.

Note: The RFP L42 WLAN must connect to a 100BaseT Ethernet to become
the WLAN service operational.

3.3.5.1 Optimizing the WLAN

Beacon Interval

Transmitting beacons requires transmission capacity. Reducing the length of
the beacon interval increases the WLAN network's ability to detect signals,
thus improving its availability. At the same time, it increases the network's
ability to adjust the mutually negotiated signal strength. A higher value, i.e. a
longer beacon interval, indirectly reduces the power consumption of the
WLAN client.
