For indoor distribution coverage of WLAN, we need to choose the right coupler

Coupling degree: C = 10log, what is the meaning of this unit of log, can you introduce it?

Is there only a power difference between couplers? How should I select couplers that are appropriate for the current scenario

Seems a coupler is a more versatile power splitter, have more options than normal splitter.

You can understand it as a power splitter with unequal output power.
In the indoor scene, the length of each antenna feeder to the AP is not the same, and the coupler is needed at this time.

: Output port power

P3: Coupling port output power

Degree of coupling : C=10log(p1/p3)

Insertion loss：IL=10log(p1/p2)

The 5dB coupler has a coupling degree of 5dB and an insertion loss of 2dB. If the input signal power is 17dBm, the coupling port output power is 12dBm.

Output port power is 15dBm.
