To get appropriate transmit power and achieve the best performance, you could adjust 3dBm each time for checking, cooperate with the Speed Test tool of Pharos to find the best performance. For example, based on the current transmit power at 12dBm, decrease it to 9dBm, 6dBm..., also increase it to 15dBm, 18dBm..., record the test results with Pharos Speed Test tool and select the most suitable value for transmission power.

I wondering how to optimize transmit power on the CP510 to find the proper balance of the lowest transmit power while retaining a high quality link.  Mine are about 100m apart so a short distance and are LOS mounted on two roofs with no obstruction.  They are currently set at 12dBm transmit power on both ends, which seemed about a 50% reduction.  I just do not want to be "blasting" any neighboring signals and just want to optimize power levels while maintaining great signal quality.
