An installer treats a 6 dB increase as only a tiny linear bump on a civic AP. What should the technician remember about dB at this depth?
Select an answer to reveal the explanation.
Short Explanation
Decibels are spicy log math — a handful of dB can mean a double or a much bigger jump depending on the step, not a cute +6 on a bathroom scale. Treat 6 dB like a real gear change in power ratio, not a rounding error.
Full Explanation
The decibel is a logarithmic relative measure of power ratios. Technician heuristics commonly associate about 3 dB with a factor-of-two power change and about 6 dB with a factor-of-four change, which is why dismissing a 6 dB shift as a trivial linear bump is incorrect. dB is not an absolute milliwatt count by itself and applies to RF power comparisons, not only PoE. Correct intuition prevents underestimating design power adjustments.
