! CW Min/Max - The size of the contention window. The contention
window backoff algorithm is a method used to resolve contention
between different stations trying to access the medium. The valid
range is from 7 to 1023.
Defaults are 31 for CW Min and 1023 for CW Max.
! RTS Threshold - The minimum packet size required for an RTS
(Request to Send) to be sent. For packets with a size below the RTS
Threshold value, an RTS is not sent and the data packet is
transmitted directly to the WLAN.
! Short Retry Limit - The maximum number of transmission
attempts for a frame that is shorter than or equal to the RTS
Threshold. The default value is 8.
! Long Retry Limit - The maximum number of transmission
attempts for a frame that is longer than the RTS Threshold. The
default value is 4.
! Basic Rate - The maximum rate of multicast, broadcast and control
frames transmissions. Multicast and broadcast transmissions are
not acknowledged; therefore there is a chance that such
transmissions will not be properly received without the possibility of
using the acknowledgement mechanism for retransmission.
Therefore, it is recommended to use a lower rate for transmission of
broadcast, multicast and control frames, to increase the probability
that they will be received without errors. Enter the data rate at
which broadcast, multicast and control frames are transmitted. The
default value is 2 Mbps.
! Power – The transmit power level. The possible range is from –
12dBm to +24dBm.
NOTE:
The Basic Rate parameter should be changed only if you are sure that all units in the cell
can handle the defined rate. Use this parameter with caution, as it may bring the link down.
