Channel Bandwidth — The AP options for channel bandwidth include 20, 40
80, and 160 MHz. The available channel bandwidth is dependent on the
802.11 Mode. (Default: 20 MHz on 2.4 GHz Radio, 80 MHz on 5 GHz Radio;
Options: 20 MHz, 40 MHz, 80MHz, 160MHz)
20MHz — For 802.11b+g+n and 802.11ax
40MHz — For 802.11b+g+n, 802.11a, 802.11a+n, 802.11ac+a+n
and 802.11ax
80MHz — For 802.11ac+a+n and 802.11ax
160MHz — (Supported only on EAP104, EAP111, and OAP101 5 GHz
radio) For 802.11ac+a+n and 802.11ax
Channel — The radio channel that the access point uses to communicate with
wireless clients. When multiple access points are deployed in the same area, set
the channel on neighboring access points at least five channels apart to avoid
interference with each other. For example, for 11g/n 20 MHz mode you can
deploy up to three access points in the same area using channels 1, 6, 11.
Note that wireless clients automatically set the channel to the same as that used
by the access point to which it is linked. (The available channels are dependent
on the 802.11 Mode, Channel Bandwidth, and Country Code settings.)
Selecting Auto enables the access point to automatically select an unoccupied
radio channel. (Default: Auto)
WME Configuration — Wireless Multimedia Extensions (WME), also known as
Wi-Fi Multimedia (WMM), is a Wi-Fi Alliance interoperability certification,
based on the IEEE 802.11e standard. It provides basic Quality of service (QoS)
features for IEEE 802.11 networks. Access priority can be configured for four
“Access Category”(AC) types using the following parameters:
CW Min (Minimum Contention Window) – The initial upper limit of the
random backoff wait time before wireless medium access can be
attempted. The initial wait time is a random value between zero and the
CWMin value. Specify the CWMin value in the range 0-15 microseconds.
Note that the CWMin value must be equal or less than the CWMax value.
CW Max (Maximum Contention Window) – The maximum upper limit
of the random backoff wait time before wireless medium access can be
attempted. The contention window is doubled after each detected collision
up to the CWMax value. Specify the CWMax value in the range 0-15
microseconds. Note that the CWMax value must be greater or equal to the
CWMin value.
AIFS (Arbitration Inter-Frame Space) – The minimum amount of wait
time before the next data transmission attempt. Specify the AIFS value in the
range 0-15 microseconds.
