General settings
•
Profile active : Activate this checkbox to activate the profile. This in turn activates the
WLAN function for all RFPs that are assigned to the WLAN profile.
•
SSID : Enter a descriptive character string to identify the WLAN network (e.g.
“OurCompany”).The service set identifier is broadcasted by the RFP within “WLAN
beacons” in a regularly interval. The SSID identifies the WLAN network and is visible by
all WLAN clients. This is typically used with a scan function, e.g. from a WLAN client that
tries to establish a connection. The SSID should not exceed 32 characters and it is
advisable not to use unusual characters that may trigger WLAN client software bugs.
•
VLAN tag (number, 1..4094, default: off): You can separate VoIP and client data traffic
(transferred via WLAN) by using different virtual LANs, e.g. to prevent bulk data transfers
to interfere with VoIP. To use a separate VLAN for the client data traffic, activate the
check box and enter the desired VLAN number (see chapters 9.15 and 9.10).
•
Beacon period (milliseconds, 50..65535, default: 100 ms): Determines the WLAN beacon
interval. A higher value can save some WLAN airtime that can be used for data transfers.
•
DTIM period (number, 1..255, default: 5): Determines the number of beacons between
DTIM messages. These messages manage the WLAN wakeup/sleep function e.g. that is
critical for battery powered WLAN clients.
•
RTS threshold (bytes, 0..4096, default: 2346): If a WLAN packet exceeds this threshold,
it will be transferred with RTS/CTS handshake. This may improve transfer reliability if
several WLANs share the same channel. The default of 2346 byte switches off this
function because the IP-MTU is typically only 1500 byte.
•
Fragmentation threshold (bytes, 0..4096, default: 2346): If a WLAN packet exceeds this
threshold, it will be transferred in chunks. This may improve transfer reliability for a weak
connection. The default of 2346 bytes switches off this function because the IP-MTU is
typically only 1500 byte.
•
Maximum rate (list of rates in Mbps, 1..54, default: 54): Determines the maximum transfer
rate used by the RFP. You can limit the rate to increase the WLAN range, e.g. to prevent
WLAN clients in the vicinity of the RFP to disturb distant WLAN clients.
•
802.11 mode (RFP (L) 42 WLAN selection list: Mixed / 802.11b-only / 802.11g-only,
default: Mixed): Both the older and long-ranged B-Mode and the newer and faster G-Mode
are typically supported by WLAN clients. You can change this setting to prevent problems
with very old WLAN clients.
(RFP (L) 43 WLAN selection list: 802.11bg /802.11b-only / 802.11g-only /
802.11abg /802.11n, default: 802.11bg): On the new
RFP43 profile you can choose
additional 802.11 modes 802.11abg and 802.11n.
Mode 802.11abg 802.11n
Open yes yes
WEP yes no
Radius (802.1x WEP) yes no
WPA v.1 (802.1x + PSK) yes no
WPA v.2 (802.1x + PSK) yes yes
•
Hidden SSID mode (on / off, default: off): If switched on, the transmission of the SSID
within beacons is suppressed. This in turn requires a more elaborate and manual
connection procedure for WLAN clients.
