A WLAN was installed at a high AP density. DTPC is lowering the transmit power of many APs too low. Which change m the DTPC transmit power threshold must be made to allow APs to globally increase AP…

Changing the threshold from 70 dBm to 73 dBm uses positive dBm values, which are not typical for RSSI thresholds that are usually negative.

Changing the threshold from -70 dBm to -73 dBm would lower the threshold, causing DTPC to potentially decrease AP transmit power further as clients would appear to have stronger signals relative to the new, lower threshold.

Changing the threshold from 70 dBm to 67 dBm uses positive dBm values and represents a decrease in the threshold, which would not result in an increase in transmit power.

DTPC uses a receive signal strength indicator (RSSI) threshold; increasing the threshold from -70 dBm to -67 dBm makes APs perceive weaker signals relative to the threshold, thereby commanding them to increase their transmit power by 3dBm to compensate.
