The table below describes the available settings:

Field

Value

Beacon Period

Beacon Period is the amount of time between beacon
transmissions. Before a station enters power save
mode, the station needs the beacon period to know
when to wake up to receive the beacon (and learn
whether there are buffered frames at the access
point). The default value is 200.

DTIM Period

DTIM stands for Delivery Traffic Indication Message.
A DTIM is a countdown field informing clients of the
next window for listening to broadcast and multicast
messages. When the access point has buffered
broadcast or multicast message for associated
clients, it sends the next DTIM with a DTIM Period
value. Access point clients hear and awaken to
receive the broadcast and multicast messages. The
default DTIM period is ‘2’.

RTS Threshold

The 802.11 standard includes the RTS/CTS (Request
to Send/Clear to Send) function to control access
of the wireless stations to the wireless medium. If
two wireless stations are transmitting packets to the
access point at the same time, the access point will
not be able to handle both, and one of the stations
will have to repeat the transmission.
If the RTS/CTS function is enabled, the station will
initiate a handshake with the destination device
(access point). After the access point finishes all
pending operations, it confirms that the station can
send the packet. This improves performance by
avoiding repeat transmissions of the same data.
The threshold value is the maximum size of a packet
which can be sent without activating the RTS/CTS
handshake. Sending a packet with a size larger
than the threshold value will activate the RTS/CTS
handshake before transmission can begin.
By default, the RTS/CTS function is disabled– the
threshold is set to 2347 bytes.
