This page allows users to set advanced settings such as operation mode, channel bandwidth,
guard interval, and aggregation MSDU for wireless data transmission.
Available settings are explained as follows:
Item Description
Operation Mode Mixed Mode – the router can transmit data with the ways
supported in both 802.11a/b/g and 802.11n standards.
However, the entire wireless transmission will be slowed
down if 802.11g or 802.11b wireless client is connected.
Green Field – to get the highest throughput, please choose
such mode. Such mode can make the data transmission
happen between 11n systems only. In addition, it does not
have protection mechanism to avoid the conflict with
neighboring devices of 802.11a/b/g.
Channel Bandwidth 20- the router will use 20Mhz for data transmission and
receiving between the AP and the stations.
20/40 – the router will use 20Mhz or 40Mhz for data
transmission and receiving according to the station
capability. Such channel can increase the performance for
data transit.
20/40/80 – the router will use 20Mhz, 40Mhz or 80Mhz for
data transmission and receiving according to the station
capability. Such channel can increase the performance for
data transit.
Guard Interval It is to assure the safety of propagation delays and
reflections for the sensitive digital data. If you choose auto
as guard interval, the AP router will choose short guard
interval (increasing the wireless performance) or long guard
interval for data transmit based on the station capability.
Aggregation MSDU
Aggregation MSDU can combine frames with different sizes
.
It is used for improving MAC layer’s performance for some
brand’s clients. The default setting is Enable.
