signal strength; signal intensity
Technical term used in contexts such as radio, Wi-Fi, and mobile networks to indicate the power level of a received signal.
The signal strength is weak in this area, so calls tend to drop.
Moving closer to the router improved the signal strength.
Refers specifically to radio wave intensity, while 信号強度 is a broader term for signal strength in any transmission system.
Means reception sensitivity, i.e., the ability of a device to detect weak signals, whereas 信号強度 is the actual measured power of the signal.
Compound of 信号 (signal) and 強度 (intensity, strength). A straightforward technical term with no obscure historical derivation.
