for long frames because sending them occupies the channel for a longer period of
time, increasing the chance that another station will transmit and cause collision.
Reducing Fragmentation Threshold results in shorter frames that "busy" the channel
for shorter periods, reducing packet error rate and resulting retransmissions.
However, shorter frames also increase overhead, degrading maximum possible
throughput, so adjusting this parameter means striking a good balance between error
rate and throughput.
Beacon Period
In wireless networking, a beacon is a packet sent by a connected device to inform
other devices of its presence and readiness. When a wirelessly networked device
sends a beacon, it includes with it a beacon interval which specifies the period of time
before it will send the beacon again. The interval tells receiving devices on the
network how long they can wait in low-power mode before waking up to handle the
beacon. Network managers can adjust the beacon interval, usually measured in
milliseconds (ms) or its equivalent, kilo microseconds (Kμsec).
DTIM interval
A Delivery Traffic Indication Message (DTIM) is a signal sent as part of a beacon by an
access point to a client device in sleep mode, alerting the device to a packet awaiting
delivery. A DTIM interval, also known as a Data Beacon Rate, is the frequency at
which an access point's beacon will include a DTIM. This frequency is usually
measured in milliseconds (ms) or its equivalent, kilo microseconds (Kμsec).
