iPECS SBG-1000 User Manual (DATA Features)
6.4.5.5.5 Wireless QoS (WMM)
Wi-Fi Multimedia (WMM) is a Wi-Fi Alliance certification, based on the IEEE 802.11e draft
standard. It provides basic Quality of Service (QoS) features to IEEE 802.11 networks. If your
gateway’s wireless card supports WMM, you can enable this feature by checking its ‘Enabled’
check box. The screen refreshes.
Figure 6.79 Wireless QoS (WMM)
Note: When working in 802.11n mode, this feature’s check box is not available as WMM is
already enabled..
6.4.5.5.6 Transmission Properties
Use this section to define the wireless transmission settings.
Figure 6.80 Transmission Properties
Transmission Rate The transmission rate is set according to the speed of your wireless
connection. Select the transmission rate from the drop-down menu, or select ‘Auto’ to have iPECS
SBG-1000 automatically use the fastest possible data transmission rate (the only option when
using 802.11ng). Note that if your wireless connection is weak or unstable, it is best to select a low
transmission rate.
Transmit Power The percentage of maximum transmission power.
CTS Protection Mode CTS Protection Mode boosts your gateway’s ability to intercept 802.11g
and 802.11b transmissions. Conversely, CTS Protection Mode decreases performance. Leave this
feature disabled unless you encounter severe communication difficulties between the gateway and
802.11g products. If enabling, select “Always”. Select “Auto” to have iPECS SBG-1000
automatically decide whether or not to use this feature.
CTS Protection Type Select the type of CTS protection—cts-only or rts-cts.
Beacon Interval A beacon is a packet broadcast by iPECS SBG-1000 to synchronize the
wireless network. The Beacon Interval value indicates how often the beacon is sent.
