LABEL DESCRIPTION
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 Zyxel Device automatically changes to use the maximum
value if you select
802.11n , 802.11gn or 802.11bgn in the Wireless LAN > General 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 Zyxel Device automatically changes to use the maximum
value if you select
802.11n , 802.11gn or 802.11bgn in the Wireless LAN > General 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 Intra-BSS is enabled, wireless
clients can access the wired network and communicate with each other. When Intra-BSS is
disabled, wireless clients can still access the wired network but cannot communicate with
each other.
Green AP Select Enable to reduce the power consumption by adjusting the output power. The Zyxel
Device reduces the output power of the transmitter from about 260mA to 188mA when there
is no IEEE 802.11 wireless clients associated with the Zyxel Device wireless network.
Tx Power Set the output power of the Zyxel Device in this field. If there is a high density of APs in an area,
decrease the output power of the Zyxel Device to reduce interference with other APs. Select
one of the following
100% , 90% , 75% , 50% , 25% or 10% .
Beacon Interval When a wirelessly networked device sends a beacon, it includes with it a beacon interval. This
specifies the time period before the device sends the beacon again. The interval tells
receiving devices on the network how long they can wait in low-power mode before waking
up to handle the beacon. A high value helps save current consumption of the access point.
