Green Field – to get the highest throughput, please choose
such mode. Such mode can make the data transmission
happening 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.
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.

WMM is an abbreviation of Wi-Fi Multimedia. It defines the priority levels for four access
categories derived from 802.1d (prioritization tabs). The categories are designed with
specific types of traffic, voice, video, best effort and low priority data. There are four
accessing categories - AC_BE , AC_BK, AC_VI and AC_VO for WMM.
APSD (automatic power-save delivery) is an enhancement over the power-save mechanisms
supported by Wi-Fi networks. It allows devices to take more time in sleeping state and
consume less power to improve the performance by minimizing transmission latency. Such
function is designed for mobile and cordless phones that support VoIP mostly.
WMM Capable To apply WMM parameters for wireless data transmission,
please click the Enable radio button.
