Network signal strength measured while saving expressed in dBm (power ratio in decibels (dB) of the measured power referenced to 1 milliwatt (mW)). Doubling this value means a 10 times stronger signal strength. Values ​​closer to 0 indicate stronger signal.
测量的网络信号强度保存时以dBm表示（以1毫瓦（mW）为单位的测量功率的分贝（dB）功率比）。将该值加倍意味着信号强度增强10倍。接近0的值表示更强的信号。
