ATPC Parameters in RB
ATPC Option
The ATPC Option enables or disables the Automatic Transmit Power
Control (ATPC) algorithm. The parameter takes effect immediately.
However, when changed from Enable to Disable, the transmit power
level shall remain at the last Current Transmit Power determined by the
ATPC algorithm before it was disabled. It will change to the value
configured for the Initial Transmit Power parameter only after the next
reset or following loss of synchronization.
The default is Enable.
Maximum Link distance (BU only)
The distance between the BU and the RB it should serve. The Maximum
Link Distance affects the maximum time that a unit will wait for a
response message (including acknowledgements of data frames and
response messages during the authentication and association process)
by taking into account the round trip propagation delay (the one-way
propagation delay at 5 GHz is 3.3 microsecond/km). This parameter is
configured in the BU, and the RB learns it during the association
process.
The range is 1-50,000 (meters) or 0 for No Compensation. No
Compensation means an acknowledge time-out of 138 microseconds.
The default is 0 (No Compensation).
Wireless Trap Threshold (BU only)
The Wireless Trap Threshold parameter defines the threshold for the
wireless quality trap, indicating that the quality of the wireless link has
dropped below (on trap) or has increased above (off trap) the specified
threshold.
The Wireless Trap Threshold is in percentage of retransmissions, and
the allowed range is from 1 to 100 (%).
The default is 30 (%).
