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.

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 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.
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.
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.
