Wireless Advanced Setup
Band Select the frequency band to set whether you want to apply the wireless and security settings
to the default 2.4G Hz or 5G Hz wireless LAN.
RTS/CTS Threshold Data with its frame size larger than this value will perform the RTS (Request To Send)/CTS (Clear
To Send) handshake.
This field is not configurable and the EMG3435-Q20A automatically changes to use the
maximum value if you select 802.11n, 802.11a n, 802.11g n or 802.11bg n in the
Expe rt >
Wire le ss screen.
Fragmentation
Threshold
The threshold (number of bytes) for the fragmentation boundary for directed messages. It is
the maximum data fragment size that can be sent.
This field is not configurable and the EMG3435-Q20A automatically changes to use the
maximum value if you select 802.11n, 802.11a n, 802.11g n or 802.11bg n in the
Expe rt >
Wire le ss screen.
Intra-BSS Traffic A Basic Service Set (BSS) exists when all communications between wireless clients or between
a wireless client and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless clients in the BSS. When you Ena b le Intra-BSS, wireless
clients can access the wired network and communicate with each other. When you Disa b le
Intra-BSS, wireless clients can still access the wired network but cannot communicate with
each other.
Tx Power Set the output power of the EMG3435-Q20A in this field. If there is a high density of APs in an
area, decrease the output power of the EMG3435-Q20A to reduce interference with other
APs. Select one of the following 100% , 90% , 75% , 50% , 25% or 10% .
QoS Setup
WMM QoS Select Ena b le to have the EMG3435-Q20A automatically give a service a priority level
according to the ToS value in the IP header of packets it sends. WMM QoS (Wifi MultiMedia
Quality of Service) gives high priority to voice and video, which makes them run more
smoothly.
This field is not configurable and the EMG3435-Q20A automatically enables WMM QoS if you
select 802.11n, 802.11a n, 802.11g n or 802.11bg n in the Expe rt > Wire le ss screen.
