Wi-Fi device IE-WL-VL-AP-BR-CL Web Console Configuration
3-39
NOTE
You can refer to the related glossaries in Appendix A for detailed information about the above-mentioned
settings. By setting these parameters properly, you can better tune the performance of your wireless network.
Transmission distance
Setting
Description
Factory Default
Distance or max. range
for transmission
(500 to 11,000 m)
Specifies the transmission distance or max. range between two
IE-WL-VL-AP-BR-CL devices. This parameter should be set
properly, especially for long-distance communication.
500
NOTE
Make sure the same Transmission distance parameters are set in both AP and Client. When this
parameter is greater than 500, an optimal algorithm will be enabled (only in the 5 GHz channel) to support
long-distance transmission.
Antenna
Setting
Description
Factory Default
A/B/Auto
Specifies the output antenna port. Setting “Antenna” to Auto
allows 2x2 MIMO communication under 802.11n and 2T2R*
communication in legacy 802.11a/b/g modes.
Auto
*Note: Different from 802.11n’s multiple spatial data stream (2x2 MIMO), which doubles the throughput, 2T2R
is transmits/receives the same piece of data on both antenna ports.
WMM
Setting
Description
Factory Default
Enable/Disable
WMM is a QoS standard for WLAN traffic. Voice and video data
will be given priority bandwidth when enabled with WMM
supported wireless clients.
Note: WMM will always be enabled under 802.11n mode.
Enable
Turbo Roaming (for Client mode only)
Setting
Description
Factory Default
Enable/ Disable
Weidmüller’s Turbo Roaming can enable rapid handover when
the IE-WL-VL-AP-BR-CL, as a client, roams among a group of
APs.
Disable
When Turbo Roaming is enabled, the following parameters will be shown:
• Roaming threshold: Determines when to start looking for new AP candidates. If the current connection
quality (SNR or Signal Strength) is lower than the specified threshold, the IE-WL-VL-AP-BR-CL will start
background scanning and look for next-hop candidates.
The following table lists the default threshold values for different RF types:
RF Type
RSSI
Signal Strength
Legacy 2.4G
30
-65
Legacy 5G
30
-65
N-mode 2.4G
40
-55
N-mode 5G
40
-50
NOTE
While the IE-WL-VL-AP-BR-CL is scanning the background, its wireless performance will be reduced by 1/3 of
its normal performance.
• Roaming difference: Determines if roaming should be executed. After background scan has been
triggered, the roaming will only occur if the AP candidate(s) provide a better (Roaming difference)
connection quality than the current connection. If multiple access points fulfill the criteria, the
IE-WL-VL-AP-BR-CL will pick the best one to roam to.
