Beacon Period (Kusec) Amount of time between beacons in
kilomicroseconds. One Kusec equals 1,024
microseconds, which is close to 1
millisecond.
DTIM Period (Beacon
intervals)
This setting, always a multiple of the
beacon period, determines how often the
beacon contains a Delivery Traffic
Indication Message (DTIM). A traffic
indication map is present in every beacon.
The DTIM notifies power-save client
devices that a packet is waiting for them.
If power save clients are active, the access
point buffers any multicast traffics and
delivers them immediately after the DTIM
beacon. Power-save nodes always wait for
the DTIM beacons. The longer the time,
the more buffering the access point does,
and the longer the multicasts are delayed.
If the beacon period is set at 100 (default
setting), and the DTM Period is set at
1(default setting), then the device sends a
beacon containing a DTIM every 100
Kusec.
Statistics Total amount in Transmission and
Reception of the following parameters
Bits The number of bits transmitted/received.
Bytes The number of bytes transmitted/
received.
Unicast Packets The number of Unicast Packets
transmitted/received.
Non-Unicast Packets The number of Non-Unicast Packets
transmitted/received.
Errors The number of errors that occurred during
transmission/reception.
Discarded he number of discards that occurred
during transmission/reception.
Total CCA Activity The relative amount of time (in
Percentage) in which Channel was busy.
The CCA (Clear Channel Assessment) is
the sum of successfully received packets
and invalid reception (false alarm)
