Signal strength dbm

WebdBm stands for decibel-milliwatts; is a dimensionless unit used to define/measure signal strength (power level), with reference to 1 milliwatt. (i.e., the power level of 0dBm represents 1milliwatt). The dBm is a convenient unit; used in radio, microwave, audio applications, and fiber-optical communications networks to measure signal strength. WebSignal strength between -55 dBm and -75 dBm is acceptable, depending on how close or far away from your wireless router you happen to be. If you’re in the same room as your wireless router and have trouble achieving good network performance, the chances are that there is a lot of environmental noise from various electronic devices and other wireless networks.
