CHAPTER 5: SYSTEM CONFIGURATION
Maximum Transmit Data Rate – The maximum data rate at which the access point
transmits unicast packets on the wireless interface. The maximum transmission
distance is affected by the data rate. The lower the data rate, the longer the
transmission distance. (Options: 54, 48, 36, 24 Mbps; Default: 54 Mbps)
Maximum Multicast Data Rate – The maximum data rate at which the access
point transmits multicast and broadcast packets on the wireless interface.
(Options: 24, 12, 6 Mbps; Default: 6 Mbps)
Beacon Interval – The rate at which beacon signals are transmitted from the
access point. The beacon signals allow wireless clients to maintain contact with
the access point. They may also carry power-management information.
(Range: 20-1000 TUs; Default: 100 TUs)
Delivery Traffic Indication Message (DTIM) – The rate at which stations in sleep
mode must wake up to receive broadcast/multicast transmissions.
The DTIM interval indicates how often the MAC layer forwards
broadcast/multicast traffic, which is necessary to wake up stations that are using
Power Save mode. The default value of 1 indicates that the access point will save
all broadcast/multicast frames for the Basic Service Set (BSS) and forward them
after every beacon. Using smaller DTIM intervals delivers broadcast/multicast
frames in a more timely manner, causing stations in Power Save mode to wake up
more often and drain power faster. Using higher DTIM values reduces the power
used by stations in Power Save mode, but delays the transmission of
broadcast/multicast frames.
(Range: 1-255 beacons; Default: 1 beacon)
Fragment Length (256~2346)– Configures the minimum packet size that can be
fragmented when passing through the access point. Fragmentation of the PDUs
(Package Data Unit) can increase the reliability of transmissions because it
increases the probability of a successful transmission due to smaller frame size. If
there is significant interference present, or collisions due to high network
utilization, try setting the fragment size to send smaller fragments. This will speed
up the retransmission of smaller frames. However, it is more efficient to set the
fragment size larger if very little or no interference is present because it requires
overhead to send multiple frames. (Range:
256-2346 bytes; Default: 2346 bytes)
RTS Threshold – Sets the packet size threshold at which a Request to Send (RTS)
signal must be sent to a receiving station prior to the sending station starting
communications. The access point sends RTS frames to a receiving station to
NOTE: When operating the access point using 5 GHz channels in a European
Community country, the end user and installer are obligated to operate the device
in accordance with European regulatory requirements for Transmit Power Control
(TPC).
