Long Retry Limit The maximum number of transmission attempts of a frame, the length of
which is greater than dot11RTSThreshold, that shall be made before a
failure condition is indicated. The default value of this attribute shall be 4.
Fragmentation
Threshold
The current maximum size, in octets, of the MPDU that may be delivered
to the PHY. An MSDU shall be broken into fragments if its size exceeds
the value of this attribute after adding MAC headers and trailers. An
MSDU or MMPDU shall be fragmented when the resulting frame has an
individual address in the Address1 field, and the length of the frame is
larger than this threshold. The default value for this attribute shall be the
lesser of 2346 or the aMPDUMaxLength of the attached PHY and shall
never exceed the lesser of 2346 or the aMPDUMaxLength of the attached
PHY. The value of this attribute shall never be less than 256.
Max. Tx MSDU Lifetime The elapsed time in TU, after the initial transmission of an MSDU, after
which further attempts to transmit the MSDU shall be terminated. The
default value of this attribute is 512.
Max Rx Life Time The MaxReceiveLifetime shall be the elapsed time in TU, after the initial
reception of a fragmented MMPDU or MSDU, after which further attempts
to reassemble the MMPDU or MSDU shall be terminated. The default
value is 512.
Table 5-34 Tx Power Parameters
Parameter Description
# Supported Power
Levels
Five or fewer power levels, depending on operator preference.
Tx Power Level
(1, highest through 5,
lowest)
The transmit power level of the access point where
1 = Maximum power allowed per Country Code setting, 2 = 50% power,
3 = 25% power, 4 = 6.25 to 12.5% power, and 5 = 0.195 to 6.25% power.
Note that the power levels and available channels are defined by the
Country Code setting, and are regulated on a country by country basis.
Tx Power Configuration Globally controlled or Customized for this access point.
Current Tx Power Level Displays the operating transmit power level from the transmit power table.
