80 dBm: 100 kW: Typical transmission power of FM radio station with 50-kilometre (31 mi) range 62 dBm: 1.588 kW: 1.5 kW is the maximum legal power output of a US ham radio station. [12] 60 dBm: 1 kW = 1,000 W: Typical combined radiated RF power of microwave oven elements 55 dBm ~300 W: Typical single-channel RF output power of a K u band ...

Examples. 100 dBμ or 100 mV/m: blanketing interference may occur on some receivers; 60 dBμ or 1.0 mV/m: frequently considered the edge of a radio station's protected area in North America; 40 dBμ or 0.1 mV/m: the minimum strength at which a station can be received with acceptable quality on most receivers
The decibel originates from methods used to quantify signal loss in telegraph and telephone circuits. Until the mid-1920s, the unit for loss was miles of standard cable (MSC). 1 MSC corresponded to the loss of power over one mile (approximately 1.6 km) of standard telephone cable at a frequency of 5000 radians per second (795.8 Hz), and matched closely the smallest attenuation detectable to a ...
dBm = 2 × ASU - 113, ASU in the range of 0.31 and 99 (for not known or not detectable). In UMTS networks, ASU maps to RSCP level (received signal code power, see TS 27.007 [3] sub clause 8.69 and TS 25.133 sub clause 9.1.1.3). dBm = ASU - 115, ASU in the range of 0.90 and 255 (for not known or not detectable).

Cellular signal strength of -74dBm (or 66 asu) displayed on a smartphone.Also shown: signal bars of two cellular networks, and signal bars of a Wi-Fi network. In telecommunications, received signal strength indicator or received signal strength indication [1] (RSSI) is a measurement of the power present in a received radio signal.
