Field Description
802.11g protection mode Enable this rate limit to prioritize 802.11g (ERP-OFDM)
transmission allowing the 802.11g device to transmit
unhindered. Protection is used when the packet rate is greater
than the configured protection limit rate. For example, if the
protection rate is set to 11Mbps, protection will be used when
sending at rates greater than 11Mbps, which means 802.11g
rates.
To maintain compatibility between the older (802.11b (HR-
DSSS) and the newer 802.11g (ERP-OFDM) ) technologies, a
mechanism was devised to allow the older 802.11b device to
understand the newer 802.11g device without significantly
lowering the data rate of the 802.11g client. The 802.11g device
sends an RTS/CTS frame sequence (Request To Send/Clear To
Send) that should be heard by all stations, it may also use only
"CTS-to-self." This sequence is understood by the 802.11b
station that reads the duration field from the frame and sets its
NAV timer to hold o the medium until this timer expires. This
allows the 802.11g to transmit unhindered. An AP notifies all
clients within its service area that there are 802.11b devices
present via a bit set in its beacons. Note: It is the newer
protocol (802.11g) being protected from the older (802.11b)
protocol.
The protection rate limit threshold determines when to use
protection.
Minimum Basic Rate Defines the minimum data rate that must be supported by all
stations in a BSS (Base Station Subsystem):
• Select 6, 9, 12, 18, 24, 36, 48, and 54. The default value is 6.
Aggregate MPDUs Determines MAC Protocol Data Unit (MPDU) aggregation.
Enable to increase the maximum frame transmission size,
providing a significant improvement in throughput.
Aggregate MPDU Max # of Sub-
frames
Maximum number of sub-frames of the MAC Protocol Data Unit
(MPDU) aggregation. The value range is 2-64.
DTIM When any single wireless client associated with an access point
has 802.11 power-save mode enabled, the access point buers
all multicast frames and sends them only after the next DTIM
(Delivery Trac Indication Message) beacon, which may be
every one, two, or three beacons (referred to as the “DTIM
interval”).
